  DDR5 Discussion Thread
Posted by: SteelCrysis - 09-23-2017, 04:46 AM - Forum: General Hardware - No Replies


Quote:DDR5, the natural successor to today's DDR4 memory that brings with double the bandwidth and density versus current generation DDR4. along with delivering improved channel efficiency, is expected to be available in the market starting 2019. JEDEC, the standards body responsible for the DDR specifications, says that base DDR5 frequencies should be at around DDR5-4800 - double that of base DDR4's 2400, but a stone throw away from today's fastest (and uber, kidney-like-expensive) 4600 MHz memory kits from the likes of G.Skill and Corsair.
On this, Rambus' vice president on product marketing, Hemant Dhulla, had this to say: ""To the best of our knowledge, we are the first to have functional DDR5 DIMM chip sets in the lab. We are expecting production in 2019, and we want to be first to market to help partners bring up the technology." On the time still ahead before market introduction of the technology, Dhulla said"(...) it's just a couple quarters, not a couple years…Everyone wants a fatter memory pipe."

  Asetek vs. Cooler Master: Asetek Loses
Posted by: SteelCrysis - 09-22-2017, 08:42 AM - Forum: General Hardware - No Replies


Quote:However, The Hague's court has accepted Cooler Master's argument that they too have a similar patent to Asetek's, through a so-called "utility model" that already exists in China, which describes (and patents really show their problems here) the "operation of a water pumping engine device with chamber". The The Hague judge also invalidated Asetek's patent lawsuit on the basis that there was not enough inventiveness to it. Asetek and Cooler Master's legal battles aren't anything new; in 2015, a US-based court ordered Cooler Master to pay Asetek $600,000 for patent infringement. This time, it's the other way around, even though it was still Asetek that started the legal battle: the company now has to pay Cooler Master for their legal expenses, which amount to around €113,000 (~$134,204)

  TechSpot's Review Of The A12-9800
Posted by: SteelCrysis - 09-22-2017, 02:13 AM - Forum: General Hardware - No Replies


Quote:If you can't already tell, we're not impressed with the A12-9800 and we strongly recommend you avoid purchasing any of the Bristol Ridge CPUs. We've thought long and hard and we can't come up with one valid reason or situation where these CPUs make an ounce of sense.

You wouldn't buy any of them as placeholders, which makes about as much sense as using a Kaby Lake-X CPU as a placeholder. Sure the Athlon X4 950 is cheap at $60, but it delivers the exact the same performance as the A12-9800 with a discrete GPU. The G4560 can be had for around $90 and it's worlds better in every single way when compared to the Athlon.

In order to use the Athlon X4 950 or the A12-9800 you need to buy a new AM4 motherboard along with some new DDR4 memory. Let's say you go with an ultra cheap A320 board for $50 and 8GB of DDR4 for $70, that means the A12-9800 upgrade package will set you back $230. The same motherboard and memory combo with the Ryzen 3 1200 plus the GeForce GT 1030 will cost $300, so that's 30% more money for over twice the CPU power, and twice the GPU power.

Meanwhile, if you opt for the Athlon X4 950 and GT 1030 combo instead, that's even worse as the Ryzen 3 1200 with the same discrete graphics card costs just 20% more.

We haven't touched on overclocking and frankly we're not going to bother. Even if you could push the A12-9800 to something insane like 5.5GHz it would still suck. Of course, it can't operate at that frequency. We've heard of people getting up to 4.8GHz and at that rate it would still struggle to keep pace with the G4560 while consuming three times more power.

Faster memory will no doubt help, assuming the memory controller can handle it, but even DDR4-4000 memory isn't going to save these Bristol Ridge CPUs. With the same DDR4-2400 memory as the G4560, we saw less than half the available bandwidth.

There's simply no saving grace here. AMD's intention was to feed the OEM channels with these rubbish chips and now they're buying a little time before the Zen-based APUs arrive next year. In our opinion they've just tainted the AM4 platform with an architecture we'd all like to forget about and I would have thought AMD felt the same way.

Anyway, our advice is to not buy these chips and instead wait for the real deal. We expect the Zen-based APUs to be something quite special and they will no doubt give Intel quite a few headaches.

  AMD Going To 12nm
Posted by: SteelCrysis - 09-21-2017, 06:50 AM - Forum: General Hardware - No Replies


Quote:At the Global Foundries Technology Conference, AMD’s CTO Mark Papermaster announced that the company will be transitioning “graphics and client products” from the Global Foundries 14nm LPP FinFET process it uses today to the new 12nm LP process in 2018. Global Foundries also announced that 12LP will begin production in 1Q18.

We followed up with Papermaster in person and confirmed directly that the company will transition both Vega GPUs and the Ryzen line of processors to the 12nm LP process. However, it’s still not clear whether or not he meant that 12nm LP will be a shrink of Ryzen in 2018 (a "tick" equivalent if you will) or if Zen+/Zen 2 will also be using the 12LP process. Previously, AMD has implied that Zen 2 will use the 7nm process. The company has used both "Zen+" and "Zen 2" to refer to its next-generation die.

We expected AMD's next-generation 7nm Zen products to slug it out with Intel's 10nm Ice Lake processors next year, but it appears we will see 12nm LP against Intel's 10nm instead.
The transition to 12nm LP also reaffirms AMD's commitment to its partnership with Global Foundries. The companies signed a five-year wafer supply agreement recently, but there has been speculation that AMD might seek other partners for its forthcoming product generations.

We're digging in deeper for more information and will follow up as required.

  300-Series Motherboards Won't Work With Kaby Lake CPUs
Posted by: SteelCrysis - 09-20-2017, 07:54 AM - Forum: General Hardware - No Replies


Quote:The upcoming Intel 300-series chipset, and LGA1151 socket continues to be a source of chaos for PC builders. While the 100-series and 200-series chipset based motherboards support both 6th generation Core "Skylake," and 7th generation Core "Kaby Lake" processors, they will not support the upcoming 8th generation Core "Coffee Lake" chips. What's more, the upcoming 300-series chipset motherboards, which were earlier believed to feature backwards-compatibility for "Skylake" and "Kaby Lake" chips, will not support them, according to a Hardware.info report.

Exclamation The DRAM Shortage Is Only Going To Get Worse
Posted by: SteelCrysis - 09-16-2017, 12:11 AM - Forum: General Hardware - Replies (2)


Quote:According to IC Insights, even though DRAM prices have more than doubled (+111%) over the last 12 months, they will only continue to increase. IC Insights predicts that by the end of the calendar year the DRAM's price per bit will have jumped a record 40% (or more).

Things change quickly in the DRAM market; just last year we were amid an oversupply that brought low prices for your favorite kits. Unfortunately, IC Insights claims the oversupply was one of the contributors to the latest price hikes. Greedy wholesalers gobbled up stock during the oversupply at low prices, but then sat on the stockpiles as the shortage deepened. Now, the wholesalers are cashing in on their bets and reaping the benefits. Meanwhile, enthusiasts can expect to pay top dollar for the latest blinky RAM kits.

Of course, the record pricing levels are great for our friends at the major foundries. Samsung, Micron, and Sk Hynix are also raking in their own record piles of cash and enjoying healthy margins. We have both DRAM and NAND shortages occurring at the same time, which is great for the foundries, and unless a player breaks ranks to gain market share, we can expect more foot-dragging before any of the foundries increases output.

The booming mobile industry and server markets are exacerbating the issue, so you would expect that the fabs would boost DRAM output. Unfortunately, the three primary fabs (Micron bought Elpida, reducing the number of players) don't share the same vision.

Micron indicates that it will not increase production capacity to satiate our RAM desires, instead relying upon mundane improvements in yields and shrinking down to smaller nodes to boost its DRAM bit output. Sk Hynix has expressed its desire to boost DRAM output but hasn't set a firm timeline for fab expansion (unlikely to occur in the near term). Samsung is as tight-lipped as usual, so we aren't sure of its intentions.

In the 1980's there were 23 major DRAM suppliers, but cutthroat pricing and continual oversupplies eventually led to the wave of consolidation that left us with the current three suppliers. Due to the nature of the DRAM oligarchy, Sk Hynix's plans could be the catalyst for future DRAM expansion at Samsung and Micron. Unfortunately, due to the complexity of today's latest DRAM nodes, these capacity expansions usually require an extended amount of time before the price reductions trickle down to us. We can expect a six month ramp time for an existing fab to reallocate space to DRAM production, or a two year process to build an entirely new fab.

In other words, if you plan on a new build in the near future it might be best to grab a RAM kit now before the prices increase further. Unless the dynamics of market demand change drastically we can expect the shortage to worsen over the next six months, and possibly longer.

  Compute Server/Space Heater Combo
Posted by: SteelCrysis - 09-15-2017, 04:22 AM - Forum: General Hardware - No Replies


Quote:Update: Qarnot has updated their page with AMD Ryzen 7 support for its 3 computing units, so it's not limited to Intel offerings. You can see the before and after screenshots on the bottom of this article.
In a move that is sure to bring the cozy, homely warm feeling back towards the space heater concept of yore - who doesn't remember AMD's mocking videos of NVIDIA's Fermi architecture - french company Qarnot has announced their third-generation iteration of a product which is sure to change the Kelvin and Celsius degrees in the computing space. The French company has decided to not let go to waste the (until now) waste heat generated by computing hardware on execution of workloads, and has instead decided to capitalize on those "wasted", byproduct degrees as means of reducing company's and users' heat bills. Their Q.rad concept takes what is usually seen as a drawback in hardware (the amount of waste heat it generates) and turns it into a net positive, by making sure that the heat generated is put to good use in increasing the otherwise chilly temperatures you might be facing.

Their Q.rad sensor makes use of three cloud-enabled Intel Core i7 processors @ 4 GHz frequency - perhaps Ryzen didn't make the cut since it is comparatively more energy efficient per core - as a way of building computing blocks that double as radiators. As Qarnot crunches data (typically, 3D rendering and VFX for film studios), its Q.rad provides up to 500 W "soft heating power" to your home. Reusing heat in such a manner reduces Qarnot's carbon footprint and provides free heating for homes and offices, and also reduces Qarnot's server space overhead, so both parties benefit. This is basically a company thinking outside the box at an old problem, and figuring out an elegant, Columbus-egg-type solution that is obvious, but hadn't been thought of yet.

  Guru3D's View Of SSD Speed
Posted by: SteelCrysis - 09-15-2017, 01:37 AM - Forum: General Hardware - No Replies

I read this and thought its conclusions about SSDs speed are good material for discussion: http://www.guru3d.com/articles_pages/ada...ew,19.html

Quote:Going from a HDD towards an SSD is made such a huge difference. Going from a fast SATA3 SSD towards NVMe M.2 again is a faster step, but admittedly a far less less to notice one, as a regular SSD is already loading your data in a split second. Access times with HDDs always have been the biggest bottleneck, that mechanical head positioning itself on the platters was eliminated. With the introduction of SSD that massive latency issue was completely killed off, and that's where 90% of the performance benefit was found. So the big question remains how fast do these SSDs really need to be ? It is a discussion that will be interesting to see in the coming years. Honestly I think the trend will be NVMe with more capacity, 99.999% reliability and endurance (TB Written) as main factors being decisive.

  Rumored GTX 1070 Ti
Posted by: SteelCrysis - 09-14-2017, 07:52 PM - Forum: Video - Replies (11)


Quote:NVIDIA is readying a new GeForce GTX 1070 refresh graphics card, according to well-placed sources. Positioned between the current GTX 1070 and the GTX 1080 11 Gbps in performance, the refreshed GTX 1070 could at least displace the current GTX 1070 from its price-point, if not replace it. NVIDIA could carve the new chip out of the latest stepping of the GP104 silicon, and give it more CUDA cores, likely 2,048 (on par with GTX 1070 Mobile), if not higher. It could also get faster memory, likely 9 Gbps GDDR5 or even 10 Gbps GDDR5X. Its core and GPU Boost clock speeds could even be dialed up a little.

NVIDIA's objective here appears to be convincingly outperforming AMD Radeon RX Vega 56, at a lower power-draw. There's a 20 percent performance gap between the current desktop GTX 1070 and GTX 1080, and the new GTX 1070 refresh could find a price-performance equation somewhere in the middle. As NVIDIA's product-stack currently stands, the GTX 1080, which was refreshed with faster 11 Gbps GDDR5X memory, has a wider performance gap with the GTX 1070, creating room for a GTX 1070 refresh SKU somewhere in the middle, which could perform within the 90th percentile of the original GTX 1080 with 10 Gbps memory. What NVIDIA could name the SKU is anybody's guess. Historically, NVIDIA has updated SKU specifications without changing the name. The GTX 1080 and GTX 1060 6 GB were refreshed with faster memory, by simply prominently mentioning the memory clock below the SKU branding, there's also the remote possibility of the GTX 1070 Ti branding to combat the "grandeur" of AMD's RX Vega branding. NVIDIA could have the new GeForce GTX 1070 refresh SKU out in time for Holiday.

  Star Wars Battlefront Season Pass For Free & Cross-Platform
Posted by: SteelCrysis - 09-13-2017, 06:33 AM - Forum: Hot Deals & Bargains - No Replies

Note what Neowin says here:

Quote:There isn't an end date listed for the promotion, so it would be best to grab it now if one is interested in returning to the shooter to play around with some new content. Interestingly, Star Wars Battlefront II will not be receiving a season pass, as EA hopes to keep the community from splintering between expansions. A beta for the sequel is slated to arrive in October, ahead of the November 17 official launch.
