  Intel 7nm Thread
Posted by: SteelCrysis - 05-09-2019, 08:09 PM - Forum: General Hardware - No Replies


Quote:When it goes live and fit for mass production some time in 2021, Intel's 7 nm process will be a staggering 3 years behind TSMC, which fired up its 7 nm node in 2018. AMD is already mass-producing CPUs and GPUs on this node. Unlike TSMC, Intel will implement EUV (extreme ultraviolet) lithography straightaway. TSMC began 7 nm with DUV (deep ultraviolet) in 2018, and its EUV node went live in March. Samsung's 7 nm EUV node went up last October. Intel's roadmap doesn't show a leap from its current 10 nm node to 7 nm EUV, though. Intel will refine the 10 nm node to squeeze out energy-efficiency, with a refreshed 10 nm+ node that goes live some time in 2020.
The 7 nm EUV node will receive two major updates in quick succession. The 7 nm+ node is slated for 2022, and succeeding 7 nm++ node in 2023. Intel did not detail the two besides illustrating performance/Watt gains by almost as much as the transition from 10 nm+ to 7 nm. Elsewhere in the market, the early 2020s could see TSMC 6 nm EUV take center-stage, and Samsung implement its 5 nm EUV node.

Intel will build an Xe enterprise GPGPU based on 7 nm EUV for market release in 2021. The company was specific in mentioning that an "enterprise GP-GPU" will be built on it, and not its entire Xe lineup that includes client-segment, professional, and cloud GPUs. The Xe discrete GPU team, led by Raja Koduri, is probably making a ropewalk, by giving Intel "something" to build on its own fabs, while seeking out Samsung's cutting-edge 5 nm EUV node for the rest of its lineup. Intel confirmed that the its first 7 nm product will be a GPGPU, followed closely by a server CPU.

Quote:Intel traditionally released new CPU microarchitectures and new silicon fabrication nodes with the client segment, and upon observing some degree of maturity with both, graduated them to the enterprise segment. With its homebrew 7 nanometer silicon fabrication process that takes flight in 2021, Intel will flip its roadmap execution strategy, by going "Data Center First." Speaking at the 2019 Investors Day summit, Intel SVP and GM of Data Center Group Navin Shenoy revealed that the first product built on Intel's 7 nm process will be a GPGPU accelerator chip derived from the Xe architecture for the Data Center, followed closely by a new server CPU. Both these products come under Shenoy's group. One is a competitor to likes of NVIDIA Tesla and AMD Radeon Instinct, while the other is a Xeon processor competing with AMD EPYC.
With 10 nm, however, Intel is sticking to the client-first model, by rolling out the "Ice Lake" processor towards the end of 2019. Within the Client Computing group, Intel has flipped its roadmap execution such that mobile (notebook) CPUs take precedence over desktop ones.

  Most popular cars of 2018 -- Turo
Posted by: gstanford - 04-23-2019, 01:34 PM - Forum: Off Topic - Replies (5)

This thread is especially for Rollo.

[Image: ViwOXof.jpg]

The above image is from US car rental company Turo and shows the 11 most popular vehicles that people rent from them (by revenue earned per vehicle model).

Note that 10 out of the 11 vehicles are passenger cars, not pickup trucks, suv's or other types of vehicle.

Note that the 1 vehicle that is not a passenger car is the jeep wrangler 4WD SUV, not a F150 pickup truck (beloved of Rollo).

Note that Toyota appears 3 times in the list at positions 3, 5 and 8.

Note that Ford and Chrysler (jeep) appear only once in the list and the only other american manufacturer in the list (Tesla) appears 3 times with electric vehicles.  GM is absent altogether.  So that is 5 places out of 11 total taken by US vehicles and 6 places for vehicles manufactured world wide.

The info in this post derived from the ArsTechnica article linked below:

  AMD 50th Anniversary Hardware
Posted by: SteelCrysis - 04-16-2019, 08:29 PM - Forum: General Hardware - Replies (6)


Quote:AMD's 50th Anniversary is fast approaching on May 1, and several new postings at online retailers have revealed that AMD is on the cusp of releasing a new 50th Anniversary Ryzen 7 2700X to celebrate. (Hat tip to @Dayman58 for the spot).

Aside from the mention of a bundled Wraith Prism LED cooler, the listings tell us little about the chip, including what differentiates it from existing Ryzen 7 2700X models. The chip is listed for preorder at $340.95, which is well above the typical ~$295 street price, but that's to be expected with a collector's item.

Several of the sites haven't listed retail availability yet, but on further investigation, we found a retailer that claims the part will become available on April 30, the day before AMD's anniversary celebration.
AMD has also released special edition chips in the past–the company released its Limited Edition Ryzen 7 2700 and Ryzen 5 2600X MAX bundles last year. Even though those chips, which come with a better Wraith Max cooler than the standard models, still haven't made their way to American shores, you can still find them for sale overseas.

Quote:Given that AMD hasn't changed the model number, we expect these processors to have the same specifications as regular Ryzen 7 2700X, but with some special packaging material, and perhaps some special laser engraving on the processor's IHS. AMD has used tin boxes in the past for its first FX-series processors, so the possibility of something similar cannot be ruled out. Since pricing of this SKU isn't significantly higher, we don't expect it to be of a higher bin (better overclockers) than regular 2700X chips.

Quote:Portuguese online retailer PCDIGA has listed the Sapphire AMD 50th Anniversary Edition Nitro+ Radeon RX 590 8GB graphics card for €299.90, or roughly $338.99, on the company's website.
The 50th Anniversary Edition will look awfully familiar if you're a fan of Sapphire products. That's because the graphics card employs the same Dual-X cooler that Sapphire has been using for some time. On this occasion, however, Sapphire has dipped the 2.2-slot cooler in gold-colored paint instead of the blue or black color that we've grown accustomed to.
The Sapphire Nitro+ Radeon RX 590 8GB AMD 50th Anniversary Edition is currently selling for €299.90 (~$338.99) on PCDIGA. While Portugal complies to the VAT (value-added tax) rules dictated by the European Union, the country is free to apply its own rate with the condition that it must be higher than 15 percent. Computer hardware should fall under the standard 23 percent rate, so if we deduct it from the price, the graphics card's price drops down to $275.60, which is a $45 premium over the Nitro+ RX 590 8GB Special Edition. That's apparently the price you pay for a collector's item.

  China Aims To Ban Cryptocurrency Mining
Posted by: SteelCrysis - 04-10-2019, 09:09 PM - Forum: Cryptocurrency Mining - No Replies


Quote:The Chinese National Development and Reform Commission (NDRC) said on Monday that it is seeking public opinions on a revised list of industries that it should encourage, restrict, or eliminate. The first version of NDRC's list appeared in 2011, and the revised list puts cryptocurrency mining on the chopping block for immediate removal.
According to Reuters, Jehan Chu, managing partner at blockchain investment firm Kenetic, told state-owned newspaper Securities Times that the Chinese government isn’t really trying to eliminate cryptocurrencies in the country for good.

  Valve, Others Hammered By EU Over Geo-Blocking
Posted by: SteelCrysis - 04-06-2019, 10:14 PM - Forum: Gaming - No Replies


Quote:Update 4/5/19, 9:20 a.m. PT: Valve sent us a statement in response to the European Commission's announcement. The company reiterated that the commission's issues don't involve sales through Steam, just Steam activation keys used by physical copies of games and said it neither receives compensation directly from the companies nor a portion of sales for providing this service.

More important is the company's claim that few titles were affected by geo-blocking, that it shouldn't be subject to any penalties for providing a platform on which other companies did wrong and that the commission's complaint arrived a few years late:

The European Commission announced today that it sent Statements of Objections to Valve, Bandai Namco, Capcom, Focus Home, Koch Media and ZeniMax for "geo-blocking" Steam activation keys for physical copies of games (which do, in fact, still exist) based on national borders.
The European Commission said Valve and the game publishers agreed to block cross-border sales involving "Czechia, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia and in some cases Romania." All of the publishers except Capcom also included export restrictions in their contracts with other game distributors that "may have prevented consumers from purchasing and playing PC video games sold by these distributors."

These restrictions are said to violate Article 101 of the Treaty on the Functioning of the European Union via Regulation 2018/302, which prohibits geo-blocking, which is why the commission sent these Statements of Objections. That regulation went into effect in December 2018, but the commission's investigation into Valve and these game publishers actually started in February 2017. Now the companies have a chance to respond.

  Digital-Only Xbox One S Thread
Posted by: SteelCrysis - 03-08-2019, 02:57 AM - Forum: Xbox One - Replies (1)


Quote:Microsoft is reportedly bringing the new console to market as a way to lower the base cost of entry into the Xbox ecosystem. Pre-orders are expected by April, with the console actually going on-sale in May. Given the rumors, we suspect the system will be reworked to lower the BoM when possible, though no additional information has been provided in terms of port loadouts or wireless support. The rumor is that Microsoft is targeting a price point as much as $100 below the current $299 Xbox One S price.

The company hasn’t forgotten its customers who still rely on discs, however. Reportedly there will be a disc-to-digital program at Microsoft stores, allowing gamers to transfer physical copies to digital licenses. Details of how this would work haven’t been rolled out and the program isn’t officially announced. There’s also supposedly a cost-reduced version of the Xbox One S coming later this year as well that would keep the ability to play physical discs but still target a price below $299.
The chart from the NPD Group, shown above, illustrates just how dramatically sales have shifted from retail to online outlets. According to NPD data, even in 2013, 46 percent of console games were still sold in physical stores. Today, that ratio has fallen to 21 percent. I’ve long been a proponent of keeping physical distribution — there are too many people with metered connections or slow download speeds for me to feel comfortable with an all-digital distribution system — but it’s clear that patterns are changing. Microsoft’s latest Xbox One will attempt to change with them.

  128-Layer 3D NAND
Posted by: SteelCrysis - 03-07-2019, 11:23 PM - Forum: General Hardware - No Replies


Quote:Toshiba and its strategic ally Western Digital are readying a high-density 128-layer 3D NAND flash memory. In Toshiba's nomenclature, the chip will be named BiCS-5. Interestingly, despite the spatial density, the chip will implement TLC (3 bits per cell), and not the newer QLC (4 bits per cell). This is probably because NAND flash makers are still spooked about the low yields of QLC chips. Regardless, the chip has a data density of 512 Gb. With 33% more capacity than 96-layer chips, the new 128-layer chips could hit commercial production in 2020-21.

  Developers Can Game Steam's "Popular Upcoming" List
Posted by: SteelCrysis - 03-06-2019, 10:24 PM - Forum: Gaming - No Replies


Quote:That list is supposed to do exactly what it says: give people an easy way to find games that are coming out soon and have attracted lots of attention. But game developer Mike Rose revealed on Twitter that the Popular Upcoming list uses a back-end release date that can differ from the date shown on a title's Steam page. Changing this date can help get a game on this list. PCGamesN first reported on the tweets.

"Here's the thing: You can set any date for your game's release in the Steam backend, and it means nothing," Rose explained in one of his tweets about the issue. "You can set a date, and let it go by. Then you can set another date, and let it go by again. Setting this date has no meaning -- except for appearing in the Upcoming list."

Developers can use this otherwise useless date to make sure their game appears on Steam's front page, then, without consequence. Rose said it's also easy to set that date and then forget to change it when a game is all-but-inevitably delayed.
As it should: being featured on Steam can mean the difference between wasting years of work on a game that didn't get the right promotion and actually seeing a return on that investment. It's not an enviable position to be in--except for the part where Valve makes money no matter what games are popular--but at least it seems like the company's thinking about how to solve this.

  Accelerators Are Going To Hit The Wall
Posted by: SteelCrysis - 03-04-2019, 10:18 PM - Forum: General Hardware - No Replies


Quote:What the team found was sobering. Performance gains in specialized silicon are fundamentally linked to the number of transistors available per millimeter of silicon over the long term, as well as the improvements to those transistors introduced with each new process node. Worse, there are fundamental limits to how much performance we can extract from improved accelerator design without simultaneous CMOS scaling improvements.

The phrase “over the long term” is important. Wentzlaff and Fuchs’ research shows that it’s not unusual for workload performance to improve dramatically when accelerators are initially deployed. Over time, as methods for optimally accelerating a given workload are explored and best practices are established, researchers converge on the most optimal approaches possible. The problems that tend to respond well to accelerators are those that are well-defined, parallelizable (think GPU workloads), and exist within a mature, well-studied domain. But this also means that the same traits that make a problem amenable to acceleration also limit the total advantage gained in the long term from doing so. The team dubs this the “accelerator wall.”

The HPC market may have had a sense of this for quite some time. Back in 2013, we wrote a story about the difficult road to exascale for mainstream supercomputers. Even back then, the TOP500 was predicting that accelerators would deliver a one-time leap in performance rankings, but not an improved rate of performance improvement.
The implications of this work are significant. It predicts domain-specific architectures will not continue to deliver significant improvements in performance once Moore’s law scaling has broken down. Even if chip designers are able to focus more tightly on improving performance in fixed transistor budgets, such gains are intrinsically limited by diminishing marginal returns for well-understood problems.

Wentzlaff and Fuch’s work points to a need for a fundamentally new approach to computing. Intel’s Meso architecture is one potential alternative. Fuchs and Wentzlaff have also suggested the use of non-CMOS materials and other types of beyond-CMOS specialization, including exploring the use of non-volatile emerging memory storage arrays as a type of workload accelerator. You can read more about the team’s effort in that domain here.
