Quote:A benchmark run of AMD's forthcoming Renoir APUhas appeared in the SiSoftware database. Well-known hardware leaker @TUM_APISAK provided a screenshot of the details on Twitter.
...
The iGPU reportedly ran up to a clock speed of 1.75 GHz. It's unknown if it was running at the reported speed during the entire benchmark or is 1.75 GHz is the peak boost speed. Either way, it's pretty impressive, since you would normally see such high clocks in discrete graphics cards, not on an APU with integrated graphics.
Like the previous Renoir chips, the one spotted today also appears to work on a "Celadon" motherboard. This is the second time that we're seeing that codename, so we suspect it's for the Renoir platform. The continued use of DDR4 memory implies that Renoir might not support LPDDR4x memory, as previously suggested.
AMD will be launching fresh 7nm Ryzen mobile chips early next year. AIDA64 recently added support for Renoir, suggesting that the new APUs might be arriving soon.

Quote:An adventurous Redditor has reportedly uncover the graphics configurations for AMD's next-generation Renoir APUs (Accelerated Processing Units). The juicy details were hidden deep inside the December 2019 edition of the AMD Bootcamp Drivers.
...
Starting with the desktop, Renoir will seemingly come in 65W and 35W flavors. There are mentions of six 65W and eight 35W Renoir APUs. The 65W models are equipped with 6 CUs (Compute Units), eight or nine CUs and 10 or 11 CUs. The 35W models, on the other hand, will start at three or four CUs, 6 CUs, 8 CUs and max out at 10 CUs.
Renoir on the mobile will allegedly adhere to the 45W and 15W TDP (thermal design power). Apparently, AMD could launch six 45W and eight 15W SKUs. The 45W chips could come with eight or nine CUs, 10 or 11 CUs and 12 or 13 CUs. The 15W models will be available with the aforementioned configurations along with the addition to the entry-level chips that start with six CUs.

The leaked Renoir chip is part of the upcoming Ryzen 4000-series APU lineup that's expected to land early next year and could paint a devastating picture for Intel's low-end processors. As it stands already, AMD's APUs put consistent pressure on Intel's lower-end parts, but moving forward to the Zen 2 microarchitecture, not to mention an eight-core die, puts Intel's Core i5 series firmly in the crosshairs.
...
The model name alone is a hint that the Ryzen 7 4700U is most likely the successor to the existing Ryzen 7 3700U. The new APU shows up on PCMark 10 with a whopping eight cores but lacks SMT (Simultaneous Multi-Threading). The Ryzen 7 4700U flaunts a 2 GHz base clock and 4.2 GHz boost clock. Being an unreleased processor, the final specifications may vary.
Even more fascinating is that the Ryzen 7 4700U allegedly continues to operate within a 15W envelope despite having double the cores of the Ryzen 7 3700U. This just goes to show that AMD's Zen 2 microarchitecture and TSMC's 7nm FinFET manufacturing process are a powerful combination that shouldn't be taken lightly.
Sadly, PCMark 10 misreported the Ryzen 7 4700U's iGPU (Integrated Graphics Processing Unit) clock speed. However, the software help us confirm Renoir's continued usage of Vega as the exhibited by the GFX902 ID. At this point, it's uncertain if the Ryzen 7 4700U will arrive with 10 or 11 Compute Units (CU).

The unidentified processor's core and thread count is currently unknown, but it reportedly runs within the 35W envelope.

It's weird seeing the words "Extreme Edition" in an AMD processor name. That naming is more of an Intel practice that dates all the way back to the Northwood Pentium 4 days.
In terms of design, the obscure Ryzen 7 APU checks in with eight CPU cores and 16 threads. It appears to operate with a 1,800 MHz base clock and 4,291 MHz boost clock. The low base clock is a hint that the APU is probably based off one of AMD's Ryzen 4000 U-series parts that run with a 15W TDP.
...
There's a strong possibility that one, or maybe both, of the mysterious APUs were designed exclusively for Microsoft. AMD has produced custom-made APUs for Microsoft's Surface devices in the past. The personalized APUs were nearly identical to the original SKUs, but Microsoft's variant had one additional Vega Compute Unit (CU). Ryzen 3000 U-series (codename Picasso) chips originally maxed out at 10 CUs, and Microsoft's tailored-made APUs bumped the count up to 11.
Howerver, AMD labeled Microsoft's APUs as "Surface Edition," not Extreme. By removing the Surface moniker from the APUs, AMD could potentially offer them to other customers as well.

Quote:It’s been obvious that AMD would bring this APU family to desktop as well, but it looks like the CPU in question may be fairly aggressive. Rumors suggest that the Ryzen 4700G is an 8C/16T CPU with a base clock of 3.6GHz, a boost clock of 4.45GHz, 4MB of L2, 8MB of L3, and a 2.1GHz maximum GPU clock, all packed into a 65W TDP.
Could it be true? It could be. Grain of salt, etc. But a move like this isn’t crazy, relative to how AMD has been evolving the overall Ryzen product family.
...
This rumor suggests that AMD could make graphics standard on all parts below the 16-core level. It’s not clear how much of a value-add this represents to modern users. APU graphics are unquestionably valuable for two reasons: You cannot lose access to a system simply because your GPU dies, and you can run multi-monitor configurations more readily if you have a built-in GPU. Relatively few people, however, find themselves in dire need of either capability on the regular.
Supposedly, the GPU onboard the Ryzen 7 4700G would be an 8-CU Vega chip with 512 cores in total, clocked at a blazing 2.1GHz. That’s incredibly fast for an onboard APU, even if clocking up that high can only make a limited amount of sense due to memory bandwidth limitations. The Ryzen 7 4700G will undoubtedly shine with high-speed memory — APUs always do — but the relatively high price of RAM as you move up the clock charts always makes this investment an uncertain proposition.
Depending on how AMD distributes and prices for the new Vega graphics core, these new APUs could be a noteworthy performance improvement on the old, especially for people who are primarily CPU-focused. AMD could also be planning a preemptive response to any changes Intel might make to its own desktop graphics with future CPU launches.

Quote:It's been a long wait, but early benchmarks of AMD's Ryzen 4000-series (codename Renoir) Zen 2 APUs are finally out in the wild. Rising dataminer @_rogame dug up 3DMark submissions for the Ryzen 7 Pro 4700G, Ryzen 5 Pro 4400G and Ryzen 3 4200G parts.
...
The Ryzen 7 4700G delivered up to 9.9% higher processing performance than the Ryzen 9 4900HS, which is the flagship chip for mobile Renoir. On the graphics end, the Ryzen 7 4700G's iGPU performed 5.3% better than the Ryzen 9 4900HS. The latter has the same number of CUs as the Ryzen 7 4700G, albeit with a slower 1,750 MHz clock.
One of the Ryzen 7 4700G's best assets is the greatly improved core count over the Ryzen 5 3400G, last generation's flagship SKU. The Ryzen 5 3400G system also employed 16GB (2x8GB) of DDR4-3200 memory, so it's pretty much a level playing field for both processors.
The 3DMark results revealed that you can expect a performance uplift up to 91.2% from the Ryzen 7 4700G in terms of processing power. The iGPU performance between both flagships was pretty close. The Ryzen 7 4700G has three less CUs than the Ryzen 5 3400G. However, AMD makes up the deficit by clocking the CUs more aggressively – up to 2,100 MHz to be exact. The Ryzen 5 3400G's iGPU, which ran at 1,700 MHz, outperformed the Ryzen 7 4700G's iGPU by 1.2%.
The Ryzen 5 Pro 4400G deserves a bit of the spotlight as well. The hexa-core APU performed up to 56.2% faster than the Ryzen 5 3400G. The iGPU performance inclines in the Ryzen 5 3400G's favor as the APU was up to 7.9% faster in the graphics test.
...
The preliminary results for desktop Renoir look very encouraging on the processing side. This much is to be expected since Zen 2 and the 7nm process node opened the doors to octa-core APUs. It's a shame that the iGPU performance didn't exhibit the same level of gains. That said, overclocking is still on the table, so perhaps it's still possible to squeeze some more performance out of the iGPU in that aspect.

SMM Callout Privilege Escalation, which security research Danny Odler discovered, enables an attacker with physical or administrative access to the victim system to manipulate the AMD Generic Encapsulated Software Architecture (AGESA) microcode inside the motherboard's firmware. This allows for the execution of malicious code that's not detectable by the operating system.
Luckily, this vulnerability can be mitigated with a simple microcode update, which seemingly doesn't bear a performance impact on the system. AMD has already distributed updated versions of its AGESA microcodes to its motherboard partners and will deliver the remaining versions by the end of this month.

Quote:VLSI engineer Fritzchens Fritz, famous for high-detail EM photography of silicon dies and annotations of them, recently published his work on AMD's 7 nm "Renoir" APU silicon. His die-shots were annotated by Nemez aka GPUsAreMagic. The floor-plan of the silicon shows that the CPU component finally dwarfs the iGPU component, thanks to double the CPU cores over the previous-gen "Picasso" silicon, spread over two CCXs (compute complexes). The CCX on "Renoir" is visibly smaller than the one on the "Zen 2" CCDs found in "Matisse" and "Rome" MCMs, as the L3 cache is smaller, at 4 MB compared to 16 MB. Being MCMs with disintegrated memory controllers, it makes more sense for CCDs to have more last-level cache per CCX.
We also see that the iGPU features no more than 8 "Vega" NGCUs, so there's no scope for "Renoir" based desktop APUs to feature >512 stream processors. AMD attempted to compensate for the NGCU deficit by dialing up engine clocks of the iGPU by over 40% compared to those on "Picasso." What caught our eye in the annotation is the PCI-Express physical layer. Apparently the die indeed has 20 PCI-Express lanes besides an additional 4 lanes that can be configured as two SATA 6 Gbps ports thanks to SerDes flexibility.
This would mean that "Renoir" can finally spare 16 lanes toward PEG (PCI-Express graphics, or the main x16 slot on your motherboard), besides 4 lanes toward the chipset-bus, and the final four lanes allocated to the M.2 NVMe slot that's wired to the AM4 socket, on a typical desktop platform. On the mobile platforms, "Renoir" processors spare no more than 8 lanes toward PEG (discrete graphics), including when paired with discrete GPUs such as the GeForce RTX 2060 (mobile), which is capable of gen 3.0 x16. Previous generation desktop APUs such as "Picasso" and "Raven Ridge" spare no more than 8 PCIe gen 3.0 lanes toward PEG, even on the desktop platform. x16 PEG capability would bolster the credentials of desktop "Renoir" processors for premium gaming PC builds, using some of the top SKUs such as the Ryzen 7 4700G.

As of this writing, on Intel’s own site, a NUC with a Core i3-10110U, 1TB HDD and 16GB of Intel Optane memory along with 4GB of RAM and Windows 10 is $587.26, more expensive than even the most expensive version of the DMAF5. However, the NUC is also available as a barebones kit to bring your own storage, RAM and OS. That NUC as a kit is $299.00. Intel also has a clear warranty, while Minisforum is less proven.
If the choice comes down to price, the Minisforum is a winner here. It is giving Intel some much-needed competition in this space with similar levels of upgradeability. Hopefully, this leads to options with more tiny computers with a larger variety of AMD processors, including the latest ones. The company told Tom’s Hardware that it is in contact with AMD and plans to start developing computers based on the Ryzen 4000 series.
It’s hard to say what final shipping models will be like. After all, the company already changed the specs once before the Indiegogo to fund and sell it even began. They should be shipping sometime soon, as our unit came in near-final packaging.
But if mini PCs are your thing, there’s room for the space to get more interesting.

...
The Ryzen 7 Pro 4750G scored 1,239 points in the single-core test and 8,288 points in the multi-core test. The Ryzen 7 3700X scored 1,242 points and 8,276 points in the same tests. The difference between the results is less than 1% so it's safe to assume that the Ryzen 7 Pro 4750G and Ryzen 7 3700X perform the same, at least in Geekbench 5. By all means, only a thorough evaluation can really decide for us, and that won't be possible until desktop Renoir is out.
Dutch retailer Centralpoint listed the Ryzen 7 Pro 4750G for $370. As always, we should take the pricing with a bit of salt for various reasons. Hardware is more expensive outside the U.S. and retailers often use placeholders for pricing. The Ryzen 7 4700G is the non-Pro Variant of the Ryzen 7 Pro 4750G and should arrive with similar performance albeit a cheaper price tag.
The Ryzen 7 3700X debuted with a $329 MSRP, but the processor is selling for as low as $273. We expect the Ryzen 7 4700G to launch with a bit higher price tag because of Vega iGPU. For now, the Ryzen 7 4700G appears to be a Ryzen 7 3700X with integrated graphics. Let's not forget that the Ryzen 7 3700X has quadruple the L3 cache, which will ultimately help it beat the APU in workloads where cache matters.

Quote:AMD has been building APUs for nearly a decade, and the chips have spent much of that time with a hand tied behind their back. AMD has almost always led in integrated graphics — the launch of Ice Lake was the only brief window that disrupted its leadership — but the CPU situation was varying degrees of bad from 2011 – 2017. The Ryzen 2400G dramatically improved the situation with a vastly superior CPU core, but buying an AMD APU meant being stuck on four cores, tops. Now, for the first time, you’ll be able to buy an eight-core Ryzen CPU with a solid integrated GPU attached to it.
...
This slide is a blowout win for AMD, but it’s also not surprising. The iGPUs on Intel’s 9th Gen chips are essentially the same solutions it’s been shipping since 2015. Intel has newer graphics on Ice Lake and Xe coming on Tiger Lake, but we haven’t gotten an updated GPU core for desktop yet.
Let’s talk about how these numbers would look if 10th Gen chips were used instead. The 1T CineBench numbers wouldn’t change much, because most of Intel’s clock increases were small, on the order of 100MHz. In MT, many of the listed Intel CPUs gained Hyper-Threading when they moved from 9th to 10th Gen, and HT is typically worth some performance. A decent rule of thumb is to assume HT will boost performance between 1.10x and 1.25x for an Intel CPU. Even if you mentally tack those performance improvements on, however, AMD still wins this single multi-threaded comparison.
...
Zen and Zen+ were desktop/HEDT launches first, while their APU laptop variants dipped a proverbial toe in the water, demonstrating that AMD could build far more competitive systems, but not immediately driving a lot of sales. AMD winning a spot in the Surface 3 Laptop last year was a big deal because so few OEMs have committed to building first-class AMD mobile systems.
In retrospect, the SL3 looks like a harbinger of things to come. One of the things I predicted when desktop Zen 3 launched last year is that we’d see the CPU truly shine in mobile. This spring proved the truth of that. We’re now seeing AMD’s APUs moving much closer in overall performance to their CPU cousins on both desktop and laptop.
I suspect AMD’s newfound technical ability to combine an improved IGP with an eight-core CPU indicates we’ll see a much smaller gap between CPU and APU launches on a given Zen version. AMD’s current manufacturing strategy is to minimize the number of different die designs it has to build while maximizing the markets it can sell its hardware into. One reason AMD might not be planning a big consumer launch for these parts is that the Zen 3 APU variants may be closer than we think.

Quote:The Ryzen 4000-series (codename Renoir) processors might not be available on the U.S. retail market. However, Asian retailers are already selling the new Zen 2-powered APUs like hotcakes. Tech publication CoolPC got its hands on the trio of Renoir APUs and has published the respective review.
Identical to AMD's modern offerings, Renoir sits on the Zen 2 microarchitecture and TSMC's 7nm FinFET process node. More importantly, Renoir brings the core count for APUs from the previous four cores up to eight cores with simultaneous multithreading (SMT) enabled. Unlike other Zen 2 chips, Renoir is still on a monolithic die, which is a good thing in certain scenarios. On the graphical end, the APUs featured revamped Vega compute units (CUs) that top out a 2,100 MHz.
...
It's fair to say that the Ryzen 7 Pro 4750G's performance is similar to the Ryzen 7 3700X. In comparison to the competition, the Ryzen 7 Pro 4750G is generally faster than the Core i7-10700K. Out of the six benchmarks, the Ryzen chip beat the Intel part in four of them. In certain workloads, the Ryzen 7 Pro 4750G even managed to get within a hair of the Ryzen 7 3800XT.
As expected, the Ryzen 5 Pro 4650G performed closely to the Ryzen 5 3600X. The difference in performance is negligible, depending on the type of workload. Thanks to the SMT, even the entry-level Ryzen 3 Pro 4350G blows the previous Ryzen 5 3400G flagship out of the water.
The Ryzen 7 Pro 4750G's eight Vega compute units (CUs) at 2,100 MHz pushed the APU to the top of the charts on both the Fire Strike and Time Spy benchmarks. The Zen 2 APU was faster than the Radeon RX 550 graphics card, which was quite impressive.
The Ryzen 5 Pro 4650G and Ryzen 3 Pro 4350G weren't any slouch either. Both APUs outperformed Nvidia's GeForce GT1030 graphics card. Unsurprisingly, the Core i7-10700 with the Intel UHD Graphics 630 iGPU came in at last place.
The Ryzen 7 Pro 4750G, Ryzen 5 Pro 4650G, and Ryzen 3 Pro 4350G delivered average frames rates of 29 FPS, 32 FPS and 35FPS on an intensive title, such as Assassin's Creed Odyssey at 1080p resolution with low settings.
Once again at 1080p, the trio of APUs put up average frame rates above the 60 FPS mark on the lowest settings in Tom Clancy's Rainbow Six: Siege. On very high settings, the APUs couldn't manage 60 FPS but outputted frame rates above 45 FPS, nonetheless.
Renoir performed amazingly on League of Legends with the highest settings. The three APUs provided average frame rates above 130 FPS at 1080p, 100 FPS at 1440p and 85 FPS at 4K.

Quote:Hot on the heels of a June story of a 11th Gen Core "Tiger Lake" processor's Gen12 Xe iGPU playing "Battlefield V" by itself (without a graphics card), Tech Epiphany bring us an equally delicious video of an AMD Ryzen 7 4700G desktop processor's Radeon Vega 8 iGPU running "Doom Eternal" by itself. id Software's latest entry to the iconic franchise is well optimized for the PC platform to begin with, but it's impressive to see the Vega 8 munch through this game at 1080p (1920 x 1080 pixels) no resolution scaling, with mostly "High" details. The game is shown running at frame-rates ranging between 42 to 47 FPS, with over 37 FPS in close-quarters combat (where the enemy models are rendered with more detail).
With 70% resolution scale, frame rates are shown climbing 50 FPS. At this point, when the detail preset is lowered to "Medium," the game inches close to the 60 FPS magic figure, swinging between 55 to 65 FPS. The game is also shown utilizing all 16 logical processors of this 8-core/16-thread processor. Despite just 8 "Vega" compute units, amounting to 512 stream processors, the iGPU in the 4700G has freedom to dial up engine clocks (GPU clocks) all the way up to 2.10 GHz, which helps it overcome much of the performance deficit compared to the Vega 11 solution found with the previous generation "Picasso" silicon.

Quote:AMD's desktop Ryzen 4000 "Renoir" APUs mark a big step forward in application performance thanks to the 7nm Zen 2 architecture, while the integrated Radeon RX Vega graphics enable smooth FHD gaming if you're willing to accept lower fidelity settings and a limited selection of titles. The chips also deliver comparatively exceptional performance in 1280x720 gaming.
AMD's decision to target the OEM and SI pre-built markets with these chips makes good business sense, but enthusiasts and DIY'ers pining for more powerful APUs can't help but feel left out. As usual, supply will typically pop up where there's plenty of demand, so we were able to score a Ryzen 7 Pro 4750G at a distributor.
...
If you're after the utmost in integrated graphics performance, the Renoir chips are undoubtedly the new king of the hill. At stock settings, the 4750G's Vega graphics engine performs roughly in line with the overclocked previous-gen Ryzen 5 3400G. After overclocking, the tuned 4750G beats the OC'd 3400G by 23% at the FHD resolution, and by 20% at 1280x720. Meanwhile, the stock Ryzen 7 4750G destroys the Core i7-10700K's UHD Graphics 630 with roughly three times as much performance with the tested FHD and 1280x720 games. After overclocking, the 4750G stretches that advantage to roughly 3.5X.
Turning to performance in desktop applications, the Ryzen 7 Pro 4750G offers 32% faster performance in single threaded workloads than the 3400G, and trails the Core i7-10700F by a mere 1%. In threaded workloads, the Ryzen 7 Pro 4750G delivers more than twice the performance of the Ryzen 5 3400G and trails the 10700F by 2.6%. Overall, Renoir represents a massive generational leap for AMD APUs in both multi- and single-threaded performance, and Intel doesn't hold any clear wins in applications that would drastically impact the purchasing decision for most users.
However, enthusiasts interested in pairing a Ryzen 4000 Renoir APU with a discrete GPU are better served looking elsewhere. AMD's own Ryzen 3 3300X provides more performance at a lower price point. Ultimately the 4750G suffers at the hands of its comparatively small 8MB cache, while the 3300X benefits from 16MB. AMD's "GameCache" marketing may seem hokey, but L3 cache capacity clearly has a big impact on Zen 2's performance in latency-sensitive workloads, like gaming. The 3300X makes a better fit for low-end systems with discrete graphics, and you could pick up a Ryzen 5 3400G for a mere $147 if you're after a less-expensive APU alternative.
Renoir makes a compelling part for small form factor and HTPC builders, and it's also the only option for pairing an APU with a B550 motherboard. Unfortunately, the chips currently sell for inflated pricing through distributors, and warranty support might vary. For instance, while the Ryzen 7 Pro 4750G unofficially commands a $309 price point, we paid $353 for our chip. As such, you can expect to see higher pricing in the grey market than we have listed in the charts, especially if price gouging takes hold. And unlike most of AMD's retail chips, it likely won't come with a bundled cooler without an upcharge. That certainly muddies the value proposition.
...
The combination of leading integrated graphics and very competitive application performance makes for a compelling part for OEMs and system integrators. Whereas the previous-gen Picasso APUs topped out at four cores, Renoir allows AMD to counter the Intel Core i3, i5, and i7 families with competitive parts in a critical part of the high-volume pre-built consumer desktop market. Meanwhile, the professional features with the Pro series address the needs of professional organizations.
For the rest of us, outside of a narrow cross-section of SFF and HTPC builders (and fanatical tuners), the Renoir desktop APUs don't make a lot of sense — largely because they aren't available at retail at reasonable prices. For dedicated GPU use, you'll often get better performance out of the Ryzen 7 3700X, thanks to its large 32MB L3 cache, at a lower price.
AMD says it has "next-gen" APUs for 400- and 500-series motherboards coming in the future, and Zen 3 processors will come later this year. It would be great to see Zen 3 launch with integrated solutions as well, but that's probably asking too much. Either way, it's probably best to wait and see what comes next rather than buying an OEM-only Renoir desktop chip right now.

https://www.techpowerup.com/270810/as-amd-ryzen-4000g-kept-out-of-diy-retail-channel-bootlegging-of-oem-parts-takes-over
Quote:AMD's decision to not launch its Ryzen 4000G "Renoir" Socket AM4 processors in the DIY retail channel has baffled many in the PC enthusiast community. The parts are now exclusively in the OEM channel, however bootlegging of these chips out of the tray is rampant in Asia. A Hong Kong based eBay seller listed several 4000G SKUs, such as the flagship Ryzen 7 PRO 4750G, at a premium.
Apparently trays of 4000G chips - which aren't even supposed to end up with SI (system integrators), and only with big OEMs (think Compal, Foxconn, Dell, Lenovo, HP, etc), have somehow made their way to Asia's PC retail malls, where they're sold piecemeal, and at a premium. You pay for a chip, and the storekeeper pops one out of the tray and hands it over to you, straight up. Don't want to deal with its pins? Why not bundle it with a compatible motherboard from the same retailer, who will install the chip on the socket for you? Listings such as this one, are fraught with all the risks of bootleg commerce - the chip comes with no warranties, and the seller accepts no returns. Your only protection against getting a paperweight in your box is PayPal. It's time AMD put an end to this bovine defecation with a retail launch.
RE: Ryzen APU Thread - SteelCrysis - 09-24-2020
https://www.tomshardware.com/news/amd-ryzen-7-5700u-materializes-in-new-benchmark
Quote:The AMD Ryzen 7 5700U (via @TUM_APISAK) has emerged in an Ashes of the Singularity submission. The model name makes it pretty clear that the chip hails from AMD's next-generation lineup that succeeds the Ryzen 4000-series (codename Renoir) APUs.
Where the Ryzen 7 5700U's belongs is currently a mystery, but there are two prospects that are being thrown around: one is Lucienne and the other is Cezanne. AMD's affection for using famous painters' surnames as the codenames for its processors is well known, and sometimes the chipmaker's selection might provide some clues.
...
According to the submission, the Ryzen 7 5700U comes equipped with eight cores and 16 threads. At first glance, the name suggests that it's the direct successor to the existing Ryzen 7 4700U, however, that doesn't seem to be the case.
While the Ryzen 7 4700U is indeed an octa-core chip, the chip lacks simultaneous multi-threading (SMT). The Ryzen 7 4800U, on the other hand, comes with a eight-cores, 16-thread design, therefore, the Ryzen 7 5700U is closer to the Ryzen 7 4800U than the Ryzen 7 4700U. It's interesting though that AMD seemingly decided to unlock the full configuration on the Ryzen 7 5700U.
The anonymous submitter tested the Ryzen 7 5700U on Ashes of the Singularity with the 1080p Low Preset on the Vulkan API. Unfortunately, there aren't any Ryzen 7 4800U or Ryzen 7 4700U submissions that match those parameters so an apples-to-apples comparison wasn't possible. Furthermore, the Ashes of the Singularity submissions don't expose the clock speeds for the processor. For now, we'll just have to wait for another leak to get a glimpse of the potential performance uplifts that AMD's Ryzen 5000-series APUs could bring to the table.
