Tagged: nvidia, gtx 1060 3gb, gtx 1060, graphics card, gpu, geforce, 1152 CUDA Cores
NVIDIA has officially announced the 3GB version of the GTX 1060 graphics card, and it indeed contains fewer CUDA cores than the 6GB version.
The GTX 1060 Founders Edition
The product page on NVIDIA.com now reflects the 3GB model, and board partners have begun announcing their versions. The MSRP on this 3GB version is set at $199, and availablity of partner cards is expected in the next couple of weeks. The two versions will be designated only by their memory size, and no other capacities of either card are forthcoming.
|GeForce GTX 1060 3GB||GeForce GTX 1060 6GB|
|Base Clock||1506 MHz||1506 MHz|
|Boost Clock||1708 MHz||1708 MHz|
|Memory Speed||8 Gbps||8 Gbps|
As you can see from the above table, the only specification that has changed is the CUDA core count, with base/boost clocks, memory speed and interface, and TDP identical. As to performance, NVIDIA says the 6GB version holds a 5% performance advantage over this lower-cost version, which at $199 is 20% less expensive than the previous GTX 1060 6GB.

Ryan posted details about the Radeon RX 470 and 460 graphics cards at the end of last month, and both are now available. Now the largest of the board partners, ASUS, has added both of these new GPUs to their Republic of Gamers STRIX series.
The STRIX Gaming RX 470 (Image: ASUS)
ASUS announced the Radeon RX 470 STRIX Gaming cards last week, and today the more affordable RX 460 GPU variant has been announced. The RX 470 is certainly a capable gaming option as it's a slightly cut-down version of the RX 480 GPU, and with the two versions of the STRIX Gaming cards offering varying levels of overclocking, they can come even closer to the performance of a stock RX 480.

The new STRIX Gaming RX 460 is significantly slower, with just 896 stream processors (to the 2048 of the RX 470) and a 128-bit memory interface (compared to 256-bit). Part of the appeal of the reference RX 460 - aside from low cost - is low power draw, as the <75W power draw allows for slot-powered board designs. This STRIX Gaming version adds a 6-pin power connector, however, which should provide additional overhead for further overclocking.
|GPU||AMD Radeon RX 470||AMD Radeon RX 470||AMD Radeon RX 460|
|Memory||4GB GDDR5||4GB GDDR5||4GB GDDR5|
|Memory Clock||6600 MHz||6600 MHz||7000 MHz|

|Dimensions||9.5" x 5.1" x 1.6"||9.5" x 5.1" x 1.6"||7.6" x 4.7" x 1.4"|
The STRIX Gaming RX 470 OC 4GB is priced at $199, matching the (theoretical) retail of the 4GB RX 480, and the STRIX Gaming RX 470 is just behind at $189. The considerably lower-end STRIX Gaming RX 460 is $139. A check of Amazon/Newegg shows listings for these cards, but no in-stock units as of early this afternoon.

HEXUS has posted their review of Sapphire's AMD Radeon RX 460 Nitro 4GB graphics card, pitting it against the NVIDIA GTX 950 and GTX 750 Ti in a 1920x1080 benchmarking battle.
Image credit: HEXUS
"Unlike the two previous AMD GPUs released under the Polaris branding recently, RX 460 is very much a mainstream part that's aimed at buyers who are taking their first real steps into PC gaming. RX 460 uses a distinct, smaller die and is to be priced from £99. As usual, let's fire up the comparison specification table and dissect the latest offering from AMD."

Tagged: video card, rumor, report, Radeon RX 480, radeon, Polaris, graphics card, gpu, amd
The Wall Street Journal is reporting that AMD's upcoming Polaris graphics cards will be priced no higher than $199, a startling move to say the least.
The report arrives via VideoCardz.com:
"According to WSJ article, Polaris GPUs will cost no more than 199 USD. First systems equipped with Polaris GPUs will be available end of June:
'Advanced Micro Devices Inc. is angling to lower the cost of virtual reality, targeting the field with a new line of graphics hardware priced at $199—half or less the cost of comparable products.
AMD said the first chips based on its new Polaris design are expected to arrive in graphics cards for personal computers at the end of June. The company aims to help push the starting cost of PCs that can deliver VR experiences as low as $799 from above $1,000.'"
The report lists the high-end Polaris card as the "RX 480", which would be a departure from the recent nomenclature (R9 290X, R9 390X). Pricing such a card this aggressively not only creates what one would hope to be an incredible price/performance ratio, but is likely an answer to NVIDIA's GTX 1080/1070 - especially considering NVIDIA's new GTX 1070 is as fast as a GTX 980 Ti.
Is the Radeon RX 480 really the top end card, or a lower-cost variant? Will there be a 490, or 490X? This report certainly doesn't answer any questions, but the possibility of a powerful new GPU for $199 is very appealing.

While Nvidia's Pascal has held the spotlight in the news recently, it is not the only new GPU architecture debuting this year. AMD will soon be bringing its Polaris-based graphics cards to market for notebooks and mainstream desktop users. While several different code names have been thrown around for these new chips, they are consistently in general terms referred to as Polaris 10 and Polaris 11. AMD's Raja Kudori stated in an interview with PC Perspective that the numbers used in the naming scheme hold no special significance, but eventually Polaris will be used across the entire performance lineup (low end to high end graphics).
Naturally, there are going to be many rumors and leaks as the launch gets closer. In fact, Tech Power Up recently came into a number of interesting details about AMD's plans for Polaris-based graphics in 2016 including specifications and which areas of the market each chip is going to be aimed at.
Citing the usual "industry sources" familiar with the matter (take that for what it's worth, but the specifications do not seem out of the realm of possibility), Tech Power Up revealed that there are two lines of Polaris-based GPUs that will be made available this year. Polaris 10 will allegedly occupy the mid-range (mainstream) graphics option in desktops as well as being the basis for high end gaming notebook graphics chips. On the other hand, Polaris 11 will reportedly be a smaller chip aimed at thin-and-light notebooks and mainstream laptops.
Now, for the juicy bits of the leak: the rumored specifications!
AMD's "Polaris 10" GPU will feature 32 compute units (CUs) which TPU estimates – based on the assumption that each CU still contains 64 shaders on Polaris – works out to 2,048 shaders. The GPU further features a 256-bit memory interface along with a memory controller supporting GDDR5 and GDDR5X (though not at the same time heh). This would leave room for cheaper Polaris 10 derived products with less than 32 CUs and/or cheaper GDDR5 memory. Graphics cards would have as much as 8GB of memory initially clocked at 7 Gbps. Reportedly, the full 32 CU GPU is rated at 5.5 TFLOPS of single precision compute power and runs at a TDP of no more than 150 watts.
Compared to the existing Hawaii-based R9 390X, the upcoming R9 400 Polaris 10 series GPU has fewer shaders and less memory bandwidth. The memory is clocked 1 GHz higher, but the GDDR5X memory bus is half that of the 390X's 512-bit GDDR5 bus which results in 224 GB/s memory bandwidth for Polaris 10 versus 384 GB/s on Hawaii. The R9 390X has a slight edge in compute performance at 5.9 TFLOPS versus Polaris 10's 5.5 TFLOPS however the Polaris 10 GPU is using much less power and easily wins at performance per watt! It almost reaches the same level of single precision compute performance at nearly half the power which is impressive if it holds true!
|R9 390X||R9 390||R9 380||R9 400-Series "Polaris 10"|
|GPU Code name||Grenada (Hawaii)||Grenada (Hawaii)||Antigua (Tonga)||Polaris 10|
|Rated Clock||1050 MHz||1000 MHz||970 MHz||~1343 MHz|
|Memory Clock||6000 MHz||6000 MHz||5700 MHz||7000 MHz|
|Memory Bandwidth||384 GB/s||384 GB/s||182.4 GB/s||224 GB/s|
|TDP||275 watts||275 watts||190 watts||150 watts (or less)|
|Peak Compute||5.9 TFLOPS||5.1 TFLOPS||3.48 TFLOPS||5.5 TFLOPS|
|MSRP (current)||~$400||~$310||~$199||$ unknown|
Note: Polaris GPU clocks esitmated using assumption of 5.5 TFLOPS being peak compute and accurate number of shaders. (Thanks Scott.)
Another comparison that can be made is to the Radeon R9 380 which is a Tonga-based GPU with similar TDP. In this matchup, the Polaris 10 based chip will – at a slightly lower TDP – pack in more shaders, twice the amount of faster clocked memory with 23% more bandwidth, and provide a 58% increase in single precision compute horsepower. Not too shabby!
Likely, a good portion of these increases are made possible by the move to a smaller process node and utilizing FinFET "tri-gate" like transistors on the Samsung/Globalfoundries 14LPP FinFET manufacturing process, though AMD has also made some architecture tweaks and hardware additions to the GCN 4.0 based processors. A brief high level introduction is said to be made today in a webinar for their partners (though AMD has come out and said preemptively that no technical nitty-gritty details will be divulged yet). (Update: Tech Altar summarized the partner webinar. Unfortunately there was no major reveals other than that AMD will not be limiting AIB partners from pushing for the highest factory overclocks they can get).
Moving on from Polaris 10 for a bit, Polaris 11 is rumored to be a smaller GCN 4.0 chip that will top out at 14 CUs (estimated 896 shaders/stream processors) and 2.5 TFLOPS of single precision compute power. These chips aimed at mainstream and thin-and-light laptops will have 50W TDPs and will be paired with up to 4GB of GDDR5 memory. There is apparently no GDDR5X option for these, which makes sense at this price point and performance level. The 128-bit bus is a bit limiting, but this is a low end mobile chip we are talking about here...
|R7 370||R7 400 Series "Polaris 11"|
|GPU Code name||Trinidad (Pitcairn)||Polaris 11|
925 MHz base (975 MHz boost)
|Memory||2 or 4GB||4GB|
|Memory Clock||5600 MHz||? MHz|
|Memory Bandwidth||179.2 GB/s||? GB/s|
|TDP||110 watts||50 watts|
|Peak Compute||1.89 TFLOPS||2.5 TFLOPS|
|MSRP (current)||~$140 (less after rebates and sales)||$?|
Note: Polaris GPU clocks esitmated using assumption of 2.5 TFLOPS being peak compute and accurate number of shaders. (Thanks Scott.)
Fewer details were unveiled concerning Polaris 11, as you can see from the chart above. From what we know so far, it should be a promising successor to the R7 370 series even with the memory bus limitation and lower shader count as the GPU should be clocked higher, (it also might have more shaders in M series mobile variants versus of the 370 and lower mobile series) and a much lower TDP for at least equivalent if not a decent increase in performance. The lower power usage in particular will be hugely welcomed in mobile devices as it will result in longer battery life under the same workloads, ideally. I picked the R7 370 as the comparison as it has 4 gigabytes of memory and not that many more shaders and being a desktop chip readers may be more widely familiar with it. It also appears to sit between the R7 360 and R7 370 in terms of shader count and other features but is allegedly going to be faster than both of them while using at least (on paper) less than half the power.
Of course these are still rumors until AMD makes Polaris officially, well, official with a product launch. The claimed specifications appear reasonable though, and based on that there are a few important takeaways and thoughts I have.
The first thing on my mind is that AMD is taking an interesting direction here. While NVIDIA has chosen to start out its new generation at the top by announcing "big Pascal" GP100 and actually launching the GP104 GTX 1080 (one of its highest end consumer chips/cards) yesterday and then over the course of the year introducing lower end products AMD has opted for the opposite approach. AMD will be starting closer to the lower end with a mainstream notebook chip and high end notebook/mainstream desktop GPU (Polaris 11 and 10 respectively) and then over a year fleshing out its product stack (remember Raja Kudori stated Polaris and GCN 4 would be used across the entire product stack) and building up with bigger and higher end GPUs over time finally topping off with its highest end consumer (and professional) GPUs based on "Vega" in 2017.
This means, and I'm not sure if this was planned by either Nvidia or AMD or just how it happened to work out based on them following their own GPU philosophies (but I'm thinking the latter), that for some time after both architectures are launched AMD and NVIDIA's newest architectures and GPUs will not be directly competing with each other. Eventually they should meet in the middle (maybe late this year?) with a mid-range desktop graphics card and it will be interesting to see how they stack up at similar price points and hardware levels. Then, of course once "Vega" based GPUs hit (sadly probably in time for NV's big Pascal to launch heh. I'm not sure if Vega is Fury X replacement only or even beyond that to 1080Ti or even GP100 competitor) we should see GCN 4 on the new smaller process node square up against NVIDIA and it's 16nm Pascal products across the board (entire lineup). Which will have the better performance, which will win out in power usage and performance/watt and performance/$? All questions I wish I knew the answers to, but sadly do not!!
Speaking of price and performance/$... Polaris is actually looking pretty good so far at hitting much lower TDPs and power usage targets while delivering at least similar performance if not a good bit more. Both AMD and NVIDIA appear to be bringing out GPUs better than I expected to see as far as technological improvements in performance and power usage (these die shrinks have really helped even though from here on out that trend isn't really going to continue...). I hope that AMD can at least match NV in these areas at the mid range even if they do not have a high end GPU coming out soon (not until sometime after these cards launch and not really until Vega, the high end GCN GPU successor). At least on paper based on the leaked information the GPUs so far look good. My only worry is going to be pricing which I think is going to make or break these cards. AMD will need to price them competitively and aggressively to ensure their adoption and success.
I hope that doing the rollout this way (starting with lower end chips) helps AMD to iron out the new smaller process node and that they are able to get good yields so that they can be aggressive with pricing here and eventually at the hgh end!
I am looking forward to more information on AMD's Polaris architecture and the graphics cards based on it!

While AMD's latest dual-GPU powerhouse comes with a rather beefy-looking liquid cooling system out of the box, the team at EK Water Blocks have nonetheless created their own full-cover block for the Pro Duo, which is now available in a pair of versions.
"Radeon™ has done it again by creating the fastest gaming card in the world. Improving over the Radeon™ R9 295 X2, the Radeon Pro Duo card is faster and uses the 3rd generation GCN architecture featuring asynchronous shaders enables the latest DirectX™ 12 and Vulkan™ titles to deliver amazing 4K and VR gaming experiences. And now EK Water Blocks made sure, the owners can get the best possible liquid cooling solution for the card as well!"
Nickel version (top), Acetal+Nickel version (bottom)
The blocks include a single-slot I/O bracket, which will allow the Pro Duo to fit in many more systems (and allow even more of them to be installed per motherboard!).
"EK-FC Radeon Pro Duo water block features EK unique central inlet split-flow cooling engine with a micro fin design for best possible cooling performance of both GPU cores. The block design also allows flawless operation with reversed water flow without adversely affecting the cooling performance. Moreover, such design offers great hydraulic performance, allowing this product to be used in liquid cooling systems using weaker water pumps.
The base is made of nickel-plated electrolytic copper while the top is made of quality POM Acetal or acrylic (depending on the variant). Screw-in brass standoffs are pre-installed and allow for safe installation procedure."
Suggested pricing is set at 155.95€ for the blocks (approx. $177 US), and they are "readily available for purchase through EK Webshop and Partner Reseller Network".

Tagged: SoC, nfme, gpu, cpu, amd
Nantong Fujitsu Microelectronics Co., Ltd. (NFME) is a Chinese company that packages and tests integrated circuits. Recently, AMD has been working with China to reach that large market, especially given their ongoing cash concerns. This time, AMD sold 85% of its stake in two locations, AMD Penang, Malaysia and AMD Suzhou, Jiangsu, China, to NFME and formed a joint venture with them, called TF-AMD Microelectronics Sdn Bhd.
I see two interesting aspects to this story.
First, AMD gets about $320 million USD in this transaction, after taxes and fees, and it also retains 15% of this venture. I am curious whether this will lead to a long-term source of income for AMD, even though the press release claims that this structure will be “cost neutral”. Either way, clearing a third of a billion dollars should help AMD to some extent. That equates to about two-to-three quarters of net-loss for the company, so it gives them about six-to-nine extra months of life on its own. That's not too bad if the transaction doesn't have any lasting consequences.
Second, NFME now has access to some interesting packaging and testing technologies. NFME's website claims that this allows them to handle dies up to 800mm2, substrates with up to 18 layers, and package sizes up to 75mm. These specifications sound like it pulls from their GPU experience, which could bring all of that effort and knowledge to completely different fields.
The press release states that 1,700 employees will be moved from AMD to this venture. They do not state whether any jobs are affected over and above this amount, though.

Tagged: rumor, report, pascal, nvidia, leak, graphics card, gpu, gddr5x, GDDR5
According to a report from VideoCardz (via Overclock.net/Chip Hell) high quality images have leaked of the upcoming GP104 die, which is expected to power the GeForce GTX 1070 graphics card.
Image credit: VideoCardz.com
"This GP104-200 variant is supposedly planned for GeForce GTX 1070. Although it is a cut-down version of GP104-400, both GPUs will look exactly the same. The only difference being modified GPU configuration. The high quality picture is perfect material for comparison."
A couple of interesting things have emerged with this die shot, with the relatively small size of the GPU (die size estimated at 333 mm2), and the assumption that this will be using conventional GDDR5 memory - based on a previously leaked photo of the die on PCB.
Alleged photo of GP104 using GDDR5 memory (Image credit: VideoCardz via ChipHell)
"Leaker also says that GTX 1080 will feature GDDR5X memory, while GTX 1070 will stick to GDDR5 standard, both using 256-bit memory bus. Cards based on GP104 GPU are to be equipped with three DisplayPorts, HDMI and DVI."
While this is no doubt disappointing to those anticipating HBM with the upcoming Pascal consumer GPUs, the move isn't all that surprising considering the consistent rumors that GTX 1080 would use GDDR5X.
Is the lack of HBM (or HBM2) enough to make you skip this generation of GeForce GPU? This author points out that AMD's Fury X - the first GPU to use HBM - was still unable to beat a GTX 980 Ti in many tests, even though the 980 Ti uses conventional GDDR5. Memory is obviously important, but the core defines the performance of the GPU.
If NVIDIA has made improvements to performance and efficiency we should see impressive numbers, but this might be a more iterative update than originally expected - which only gives AMD more of a chance to win marketshare with their upcoming Radeon 400-series GPUs. It should be an interesting summer.

Another reported photo of an upcoming GTX 1080 graphics card has appeared online, this time via a post on Baidu.
(Image credit: VR-Zone, via Baidu)
The image is typically low-resolution and features the slightly soft focus we've come to expect from alleged leaks. This doesn't mean it's not legitimate, and this isn't the first time we have seen this design. This image also appears to only be the cooler, without an actual graphics card board underneath.
We have reported on the upcoming GPU rumored to be named "GTX 1080" in the recent past, and while no official announcement has been made it seems safe to assume that a successor to the current 900-series GPUs is forthcoming.
