Raw Data is an early access game for the HTC Vive, one which requires space to move and which allows the Vive to show off its tracking ability. [H]ard|OCP wanted to see how the GPUs found in most high end systems would perform in this VR game and so grabbed several AMD and NVIDIA cards to test out. Benchmarking VR games is not an easy task, instead of raw performance you need to focus on the dropped frames and unstable fps which result in nausea and a less engrossing VR experience. To that end [H] has played the game numerous times on a variety of GPUs with settings changing throughout to determine the sweet spot for the GPU you are running. VR offers a new gaming experience and new tests need to be developed to demonstrate performance to those interested in jumping into the new market. Check out the full review to see what you think of their methodology as well as the raw performance of the cards.
"Both AMD and NVIDIA have had a lot to say about "VR" for a while now. VR is far from mainstream, but we are now seeing some games that are tremendously compelling to play, putting you in middle of the action. Raw Data is one of those, and it is extremely GPU intensive. How do the newest GPUs stack up in Raw Data?"

Following the official launch of AMD's Radeon RX 470 GPU, Sapphire has unleashed its own custom graphics card with the Nitro+ RX 470 in 4GB and 8GB factory overclocked versions. Surprisingly, the new cards are up for purchase now at various retailers at $210 for the 4GB model and $240 for the 8GB model (more on that in a bit).
The new Nitro+ RX 470 uses the same board and cooler design as the previously announced Nitro+ RX 480 which is a good thing both for Sapphire (less R&D cost) and for consumers as they get a rather beefy cooler that should allow them to push the RX 470 clocks quite a bit. The card uses the same Dual X cooler with two 95mm quick connect fans, three nickel plated copper heatpipes, and an aluminum fin stack. The card features the same black fan shroud and black and silver colored backplate. Out of the box this cooler should keep the RX 470 GPU running cooler and quieter than the RX 480, but it should also enable users to get higher clocks out of the smaller GPU (less cores means less heat and more overclocking headroom assuming you get a good chip from the silicon lottery).
Sapphire is using Black Diamond 4 chokes and a 4+1 power phase design that is driven by a single 8-pin PCI-E power connector (and up to 75W from the motherboard slot). This mirrors the design of its RX 480 sibling.
Display outputs include a single DVI, two HDMI 2.0b, and two DisplayPort 1.4 ports.
The chart below outlines the comparison between the Nitro+ RX 470 cards, RX 470 reference specifications, and the RX 480.
Nitro+ RX 470 4GB
|Nitro+ RX 470 8GB||RX 470 Reference||RX 480|
|GPU Clock (Base)||1143 MHz||1121 MHz||926 MHz||1120 MHz|
|GPU Clock (Boost)||1260 MHz||1260 MHz||1206 MHz||1266 MHz|
|Memory||4GB GDDR5 @ 7 GHz||8GB GDDR5 @ 8 GHz||4 or 8 GB GDDR5 @ 6.6 GHz||4 or 8 GB GDDR5 @ up to 8 GHz|
|Memory Bandwidth||224 GB/s||256 GB/s||211 GB/s||256 GB/s|
|GPU||Polaris 10||Polaris 10||Polaris 10||Polaris 10|
|Price||$210||$240||$180+||$200+ ($240+ for 8GB)|
The RX 470 GPU is only slightly cut down from RX 480 in that it features four fewer CUs though the processor maintains the same number of ROP units and the same 256-bit memory bus. Reference clocks are 926 MHz base and 1206 MHz boost. Memory can be up to 8GB of GDDR5 with reference memory clocks of 6.6 GHz (effective). Sapphire has overclocked both the GPU and memory with the NItro+ series. The Nitro+ RX 470 with 4GB of GDDR5 is clocked at 1143 MHz base, 1260 MHz boost, and 7 GHz memory while the 8GB version has a lower base clock of 1121 but a higher memory clock of 8 GHz.
The 8GB model having a lower base overclock is a bit strange to me, but at least they are rated at the same boost clock. These specifications are very close to the RX 480 actually and with a bit of user overclocking beyond the factory overclock you could get even closer to the performance of it.
The problem with this RX 470 that gets so close to the RX 480 though is that the price is also very close to reference RX 480s! The Sapphire Nitro+ RX 470 4GB is priced at $209.99 while the Nitro+ RX 470 8GB is $239.99.
These prices put the card well into RX 480 territory though not quite up to the MSRPs of factory overclocked RX 480s (e.g. Sapphire's own Nitro+ RX 480 is $219 and $269 for 4GB and 8GB respectively). The company has a nice looking (and hopefully performing) RX 470, but it is going to be tough to choose this card over a RX 480 that has more shaders and TMUs. One advantage though is that this is a card that will just work without having to manually overclock (though where is the fun in that? heh) and it is actually available right now unlike the slew of RX 480 cards that have been launched but are consistently out of stock everywhere! If you simply can't wait for a RX 480, this might not be a bad option.
EDIT: Of course the 8GB model goes out of stock at Newegg as I write this and Amazon's prices are higher than MSRP! hah.

AMD and its board partners will officially launch the first Polaris 11 GPU and the Radeon RX 460 graphics cards based around that processor on August 8th. Fortunately Videocardz.com got a hold of an image that shows off Sapphire's take on the RX 460 in the form of a factory overclocked and custom cooled RX460 Nitro OC. This gives us a hint at the kinds of cards we can expect and it appears to be good news for budget gamers as it suggests that there will be several options around this firm $100 price point that are a bit more than the bare necessities.
In the case of Sapphire's RX 460 Nitro OC, it uses a custom dual fan cooler with two copper heatpipes, an aluminum fin stack (that is much larger than reference), and two 90mm fans. Display IO includes one DVI, one HDMI, and one DisplayPort. The card itself uses a physical PCI-E x16 connector that is electrically PCI-E 3.0 x8. The x8 connection will be more than enough for this GPU though it also enables partners to cut costs.
Clockspeeds are not yet known, but the Polaris 11 GPU (896 cores, 56 TMUs, 16 ROPs) will be paired with 4GB GDDR5 memory.
It is encouraging to me to see custom cards at this price point out of the gate with the full 4GB of memory (AMD allows 2GB or 4GB versions). Gamers that simply can't justify spending much more than a hundred dollars on a GPU should have ample options to choose from and I am looking forward to seeing what all the partners have to offer.
Are you looking at Polaris 11 and the RX 460 for a super budget gaming build? What do you think about Sapphire's card with the company's custom cooler?

Tagged: xfx, rx 470, polaris 10, Double Dissipation Edition, amd
AMD's budget (under $200) Polaris-based graphics cards are coming next week, and the leaks are starting to appear online. In the case of the Radeon RX 470, AMD is expecting that most (if not all) of its board partners will be using their own custom coolers. Thanks to Chinese technology site EXPReview, we finally have an idea of what an RX 470 will look like – or at least what an XFX-branded RX 470 will look like!
The website posted several photos of the alleged (but likely legitimate) XFX RX 470 "Black Wolf" graphics card which will probably be branded as the XFX RX 470 Double Dissipation in North America. This is a dual slot card with dual fan cooler that measures 9.45 inches long. Three copper heat pipes pull heat into an aluminum heatsink that is cooled by two 80mm fans that can reportedly be removed by the user for cleaning (and maybe user RMA replacement like Sapphire is planning). The card also features a full backplate and LED-backlit XFX logo along the side of the card. The design is all black with a white XFX logo.
Video outputs include three DisplayPort 1.4, one HDMI 2.0b, and one DL-DVI which seems about right for this price point.
The card is powered by a single 6-pin PCI-E power connector and the card will use AMD's RX 470 GPU and 4GB of GDDR5 memory. The RX 470 features 2048 cores, 128 texture units, and 32 raster operators, This is essentially a RX 480 GPU with four less Compute Units though it maintains the same number of ROPs and the same 256-bit memory bus. We do not know clockspeeds on this custom cooled XFX card yet, but overclockers may well be able to push clocks further than they could on RX 480 (there are less cores so the chips may be able to be pushed further on clocks), but it is hard to say right now. I would expect out of the box clocks to be a bit above the reference RX 470 clocks of 926 MHz base and 1206 MHz boost.
You can check out all of the photos of this card here.
Stay tuned to PC Perspective for more RX 470 and RX 460 news as we near the official launch dates!

We know pretty much all there is to know about AMD's new Polaris architecture thanks to our Radeon RX 480 review, but AMD is taking the covers off of the lower priced, lower performance products based on the same architecture tonight. We previously covered AMD's launch event in Australia where the company officially introduced the Polaris 10 RX 470 and Polaris 11 RX 460 and talked about the broader specifications. Now, we have a bit more information to share on specifics and release dates. Specifically, AMD's RX 470 will launch on Thursday, August 4th and the RX 460 will launch on the following Monday, August 8th.
First up is the Radeon RX 470, based on the same Polaris 10 GPU as the RX 480, but with some CUs disabled to lower performance and increase yields.
This card is aimed at 1080p gaming at top quality settings with AA enabled at 60 FPS. Obviously that is a very vague statement, but it gives you an idea of what price point and target segment the RX 470 is going after.
The only comparison we have from AMD pits the upcoming RX 470 against the R9 270, where Polaris offers a range from 1.5x to 2.4x improvement in a handful of titles, which include DX12 and Vulkan enabled games, of course.
From a specifications stand point, the RX 470 will include 2048 stream processors running at a base clock of 926 MHz and a rated boost frequency of 1206 MHz. That gives us 4.9 TFLOPS of theoretical peak performance to pair with a 6.6 Gbps memory interface capable of 211 GB/s of peak bandwidth. With a 4GB frame buffer and a 120 watt TDP, the RX 470 should offer some compelling performance in the ~$150 price segment (this price is just a guess on my part... though yields should be better – they can salvage RX 480s – and partners being able to use memory chips that do not have to hit 8 Gbps should help to lower costs).
Going down another step to the Radeon RX 460, AMD is targeting this card at 1080p resolutions at "high" image quality settings. The obvious game categories here are eSports titles like MOBAs, CS: Go, Overwatch, etc.
Again, AMD provides a comparison to other AMD hardware: in this case the R7 260X. You'll find a 1.2x to 1.3x performance improvements in these types of titles. Clearly we want to know where the performance rests against the GeForce line but this comparison seems somewhat modest.
Based on the smaller Polaris 11 GPU, which is a new chip that we have not seen before, the RX 460 features up to 2.2 TFLOPS of computing capability with 896 stream processors (14 CUs enabled out of 16 total in full Polaris 11) running between 1090 MHz and 1200 MHz. The memory system is actually running faster on the RX 460 than the RX 470, though with half the memory bus width at 128-bits. The TDP of this card is sub-75 watts and thus we should find cards that don't require any kind of external power. The RX 460 GPU will be used in desktop cards as well as notebooks (though with lower TDPs and clocks).
The chart below outlines the comparison between the three known Polaris graphics processors.
|RX 480||RX 470||RX 460|
|GPU Clock (Base)||1120 MHz||926 MHz||1090 MHz|
|GPU Clock (Boost)||1266 MHz||1206 MHz||1200 MHz|
|Memory||4 or 8 GB GDDR5||4 or 8 GB GDDR5||2 or 4 GB GDDR5|
|Memory Bandwidth||256 GB/s||211 GB/s||112 GB/s|
|GPU||Polaris 10||Polaris 10||Polaris 11|
There is still much to learn about these new products, most importantly, prices. AMD is still shying away from telling us that important data point. The RX 470 will be on sale and will have reviews on August 4th, with the RX 460 following that on August 8th, so we'll have details and costs in our hands very soon.
It is not clear how many or what kinds of cards we can expect to see on the August 4th and August 8th release days though it would stand to reason that they will be mostly based upon reference designs especially for the RX 460 (though Gamer's Nexus did spot a dual fan Sapphire card).. With that said, we may see custom cooled RX 470 graphics cards because while AMD does technically have a reference design with blower style cooler the company expects most if not all of its partners to go their own direction with this board including their own single and dual fan coolers.
For gamers looking to buy into the truly budget card segment, stay tuned just a little longer!

UPDATE (July 27th, 1am ET): More information on the Radeon Pro SSG has surfaced since the original article. According to AnandTech, the prototype graphics card actually uses an AMD Fiji GPU. The Fiji GPU is paired onboard PCI-E based storage using the same PEX8747 bridge chip used in the Radeon Pro Duo. Storage is handled by two PCI-E 3.0 x4 M.2 slots that can accommodate up to 1TB of NAND flash storage. As I mentioned below, having the storage on board the graphics card vastly reduces latency by reducing the number of hops and not having to send requests out to the rest of the system. AMD had more numbers to share following their demo, however.
From the 8K video editing demo, the dual Samsung 950 Pro PCI-E SSDs (in RAID 0) on board the Radeon Pro SSG hit 4GB/s while scrubbing through the video. That same video source stored on a Samsung 950 Pro attached to the motherboard had throughput of only 900MB/s. In theory, reaching out to system RAM still has raw throughput advantages (with DDR4 @ 3200 MHz on a Haswell-E platform theroretically capable of 62 GB/s reads and 47 GB/s writes though that would be bottlenecked by the graphics card having to go over the PCI-E 3.0 x16 link and it's maximum of 15.754 GB/s.). Of course if you can hold it in (much smaller) GDDR5 (300+GB/s depending on clocks and memory bus width) or HBM (1TB/s) and not have to go out to any other storage tier that's ideal but not always feasible especially in the HPC world.
However, having onboard storage on the same board as the GPU only a single "hop" away vastly reduces latency and offers much more total storage space than most systems have in DDR3 or DDR4. In essence, the solid state storage on the graphics card (which developers will need to specifically code for) acts as a massive cache for streaming in assets for data sets and workloads that are highly impacted by latency. This storage is not the fastest, but is the next best thing for holding active data outside of GDDR5/x or HBM. For throughput intensive workloads reaching out to system RAM will be better Finally, reaching out to system attached storage should be the last resort as it will be the slowest and most latent. Several commentors mentioned using a PCI-E based SSD in a second slot on the motherboard accessed much like GPUs in CrossFire communicate now (DMA over the PCI-E bus) which is an interesting idea that I had not considered.
Per my understanding of the situation, I think that the on board SSG storage would still be slightly more beneficial than this setup but it would get you close (I am assuming the GPU would be able to directly interact and request data from the SSD controller and not have to rely on the system CPU to do this work but I may well be mistaken. I will have to look into this further and ask the experts heh). On the prototype Radeon Pro SSG the M.2 slots are actually able to be seen as drives by the system and OS so it is essentially acting as if there was a PCI-E adapter card in a slot on the motherboard holding those drives but that may not be the case should this product actually hit the market. I do question their choice to go with Fiji rather than Polaris, but it sounds like they built the prototype off of the Radeon Pro Duo platform so I suppose it would make sense there.
Hopefully the final versions in 2017 or beyond use at least Vega though :).
Alongside the launch of new Radeon Pro WX (workstation) series graphics cards, AMD teased an interesting new Radeon Pro product: the Radeon Pro SSG. This new professional graphics card pairs a Polaris GPU with up ot a terabyte of on board solid state storage and seeks to solve one of the biggest hurdles in GP GPU performance when dealing with extremely large datasets which is latency.
One of the core focuses of AMD's HSA (heterogeneous system architecture) is unified memory and the ability of various processors (CPU, GPU, specialized co-processors, et al) to work together efficiently by being able to access and manipulate data from the same memory pool without having to copy data bck and forth between CPU-accessible memory and GPU-accessible memory. With the Radeon Pro SSG, this idea is not fully realized (it is more of a sidestep), but it will move performance further. It does not eliminate the need to copy data to the GPU before it can work on it, but once copied the GPU will be able to work on data stored in what AMD describes as a one terabyte frame buffer. This memory will be solid state and very fast, but more importantly it will be able to get at the data with much lower latency than previous methods. AMD claims the solid state storage (likely NAND but they have not said) will link with the GPU over a dedicated PCI-E bus. I suppose that if you can't bring the GPU to the data, you bring the data to the GPU!
Considering AMD's previous memory champ – the Radeon W9100 – maxed out at 32GB of GDDR5, the teased Radeon Pro SSG with its 1TB of purportedly low latency onboard flash storage opens up a slew of new possibilities for researchers and professionals in media, medical, and scientific roles working with massive datasets for imaging, creation, and simulations! I expect that there are many professionals out there eager to get their hands on one of these cards! They will be able to as well thanks to a beta program launching shortly, so long as they have $10,000 for the hardware!
AMD gave a couple of examples in their PR on the potential benefits of its "solid state graphics" including the ability to image a patient's beating heart in real time to allow medical professionals to examine and spot issues as early as possible and using the Radeon Pro SSG to edit and scrub through 8K video in real time at 90 FPS versus 17 with current offerings. On the scientific side of things being able to load up entire models into the new graphics memory (not as low latency as GDDR5 or HBM certainly) will be a boon as will being able to get data sets as close to the GPU as possible into servers using GPU accelerated databases powering websites accessed by millions of users.
It is not exactly the HSA future I have been waiting for ever so impatiently, but it is a nice advancement and an intriguing idea that I am very curious to see how well it pans out and if developers and researchers will truly take advantage of and use to further their projects. I suspect something like this could be great for deep learning tasks as well (such as powering the "clouds" behind self driving cars perhaps).
Stay tuned to PC Perspective for more information as it develops.
This is definitely a product that I will be watching and I hope that it does well. I am curious what Nvidia's and Intel's plans are here as well! What are your thoughts on AMD's "Solid State Graphics" card? All hype or something promising?

Tagged: siggraph 2016, Siggraph, capsaicin, amd, 3D rendering
At their Capsaicin Siggraph event tonight AMD has announced that what was previously announced as the FireRender rendering engine is being officially launched as AMD Radeon ProRender, and this is becoming open-source as part of AMD's GPUOpen initiative.
From AMD's press release:
AMD today announced its powerful physically-based rendering engine is becoming open source, giving developers access to the source code.
As part of GPUOpen, Radeon ProRender (formerly previewed as AMD FireRender) enables creators to bring ideas to life through high-performance applications and workflows enhanced by photorealistic rendering.
GPUOpen is an AMD initiative designed to assist developers in creating ground-breaking games, professional graphics applications and GPU computing applications with much greater performance and lifelike experiences, at no cost and using open development tools and software.
Unlike other renderers, Radeon ProRender can simultaneously use and balance the compute capabilities of multiple GPUs and CPUs – on the same system, at the same time – and deliver state-of-the-art GPU acceleration to produce rapid, accurate results.
Radeon ProRender plugins are available today for many popular 3D content creation applications, including Autodesk® 3ds Max®, SOLIDWORKS by Dassault Systèmes and Rhino®, with Autodesk® Maya® coming soon. Radeon ProRender works across Windows®, OS X and Linux®, and supports AMD GPUs, CPUs and APUs as well as those of other vendors.
