MSI's Radeon R9 285 GAMING OC does not yet show up for sale but with it's factory overclock may arrive at a slightly higher price than the MSRP of $250.  The RAM remains at the default 5.5 GHz but the GPU has been bumped up 55MHz to 973MHz out of the box and could likely be pushed higher as MSI has included the usual suspects on this card, Twin Frozr IV Advanced and Military Class 4 components.  In [H]ard|OCP's testing the card was well matched by the GTX 760, the HD 285 won more than it lost, but not always and not by much.  Compared to the HD 280 not only did the new Tonga card usually provide better performance but the additional feature the GPU supports, of which FreeSync is only one, make the HD 285 the clear winner in that contest.  Check their full review for benchmarks.

Tonga GPU Features

On December 22, 2011, AMD launched the first 28nm GPU based on an architecture called GCN on the code name Tahiti silicon. That was the release of the Radeon HD 7970 and it was the beginning of an incredibly long adventure for PC enthusiasts and gamers. We eventually saw the HD 7970 GHz Edition and the R9 280/280X releases, all based on essentially identical silicon, keeping a spot in the market for nearly 3 years. Today AMD is launching the Tonga GPU and Radeon R9 285, a new piece of silicon that shares many traits of Tahiti but adds support for some additional features.

Replacing the Radeon R9 280 in the current product stack, the R9 285 will step in at $249, essentially the same price. Buyers will be treated to an updated feature set though including options that were only previously available on the R9 290 and R9 290X (and R7 260X). These include TrueAudio, FreeSync, XDMA CrossFire and PowerTune.

Many people have been calling this architecture GCN 1.1 though AMD internally doesn't have a moniker for it. The move from Tahiti, to Hawaii and now to Tonga, reveals a new design philosophy from AMD, one of smaller and more gradual steps forward as opposed to sudden, massive improvements in specifications. Whether this change was self-imposed or a result of the slowing of process technology advancement is really a matter of opinion.

AMD Announces Radeon R9 285X and R9 285 Graphics Card

Subject: Graphics Cards | August 23, 2014 - 10:46 AM |
Tagged: radeon, r9 285, R9, amd, 285

Today during AMD's live stream event celebrating 30 years of graphics and gaming, the company spent a bit of time announcing and teasing a new graphics card, the Radeon R9 285X and R9 285. Likely based on the Tonga GPU die, the specifications haven't been confirmed but most believe that the chip will feature 2048 stream processors, 128 texture units, 32 ROPs and a 256-bit memory bus.

r9285.jpg

In a move to help donate to the Child's Play charity, AMD currently has an AMD Radeon R9 285 on Ebay. It lists an ASUS built Strix-style cooled retail card, with 2GB of memory being the only specification that is visible on the box.

r92852.jpg

The R9 285X and R9 285 will replace the R9 280X and R9 280 more than likely and we should see these shipping and available in very early September.

UPDATE: AMD showed specifications of the Radeon R9 285 during the live stream.

r92853.jpg

For those of you with eyes as bad as mine, here are the finer points:

  • 1,792 Stream Processors
  • 918 MHz GPU Clock
  • 3.29 TFLOPS peak performance
  • 112 Texture units
  • 32 ROPs
  • 2GB GDDR5
  • 256-bit memory bus
  • 5.5 GHz memory clock
  • 2x 6-pin power connectors
  • 190 watt TDP
  • $249 MSRP
  • Release date: September 2nd

These Tonga GPU specifications are VERY similar to that of the R9 280: 1792 stream units, 112 texture units, etc. However, the R9 280 had a wider memory bus (384-bit) but runs at 500 MHz lower effective frequency. Clock speeds on Tonga look like they are just slightly lower as well. Maybe most interesting is the frame buffer size drop from 3GB to 2GB.

That's all we have for now, but I expect we'll have our samples in very soon and expect a full review shortly!

UPDATE 2: Apparently AMD hasn't said anything about the Radeon R9 285X, so for the time being, that still falls under the "rumor" category. I'm sure we'll know more soon though.

Meet Tonga, soon to be your new Radeon

Tagged: tonga, radeon, FirePro W7100, amd

A little secret popped out with the release of AMD's FirePro W7100, a new family of GPU that goes by the name of Tonga, which is very likely to replace the aging Tahiti chip that has been used since the HD 7900 series.  The stats that The Tech Report saw show interesting changes from Tahiti including a reduction of the memory interface to 256-bit which is in line with NVIDIA's current offerings.  The number of stream processors might be reduced to 1792 from 2048 but that is based on the W7100 and it the GPUs may be released with the full 32 GCN compute units.  Many other features have seen increases, the number of Asynchronous Compute Engines goes from 2 to 8, the number of rasterized triangles per clock doubles to 4 and it adds support for the new TrueAudio DSP and CrossFire XDMA.

"The bottom line is that Tonga joins the Hawaii (Radeon R9 290X) and Bonaire (R7 260X) chips as the only members of AMD' s GCN 1.1 series of graphics processors. Tonga looks to be a mid-sized GPU and is expected to supplant the venerable Tahiti chip used in everything from the original Radeon HD 7970 to the current Radeon R9 280."

Time to update your Gallium3D

Tagged: radeon, Gallium3D, catalyst 14.6 Beta, linux, ubuntu 14.04

The new Gallium3D is up against the open source Catalyst 14.6 Beta, running under Ubuntu 14.04 and both the 3.14 and 3.16 Linux kernels, giving Phoronix quite a bit of testing to do.  They have numerous cards in their test ranging from an HD 6770 to an R9 290 though unfortunately there are no Gallium3D results for the R9 290 as it will not function until the release of the Linux 3.17 kernel.  Overall the gap is closing, the 14.6 Beta still remains the best performer but the open source alternative is quickly closing the gap.

"After last week running new Nouveau vs. NVIDIA proprietary Linux graphics benchmarks, here's the results when putting AMD's hardware on the test bench and running both their latest open and closed-source drivers. Up today are the results of using the latest Radeon Gallium3D graphics code and Linux kernel against the latest beta of the binary-only Catalyst driver."

The Radeon R9 280

Though not really new, the AMD Radeon R9 280 GPU is a part that we really haven't spent time with at PC Perspective. Based on the same Tahiti GPU found in the R9 280X, the HD 7970, the HD 7950 and others, the R9 280 fits at a price point and performance level that I think many gamers will see as enticing. MSI sent along a model that includes some overclocked settings and an updated cooler, allowing the GPU to run at its top speed without much noise.

With a starting price of just $229 or so, the MSI Radeon R9 280 Gaming graphics cards has some interesting competition as well. From the AMD side it butts heads with the R9 280X and the R9 270X. The R9 280X costs $60-70 more though and as you'll see in our benchmarks, the R9 280 will likely cannibalize some of those sales. From NVIDIA, the GeForce GTX 760 is priced right at $229 as well, but does it really have the horsepower to keep with Tahiti?

AMD Planning Open Source GameWorks Competitor, Mantle for Linux

Subject: Graphics Cards | June 19, 2014 - 10:35 AM |
Tagged: video, richard huddy, radeon, openworks, Mantle, freesync, amd

On Tuesday, AMD's newly minted Gaming Scientist, Richard Huddy, stopped by the PC Perspective office to talk about the current state of the company's graphics division. The entire video of the interview is embedded below but several of the points that are made are quite interesting and newsworthy. During the discussion we hear about Mantle on Linux, a timeline for Mantle being opened publicly as well as a surprising new idea for a competitor to NVIDIA's GameWorks program.

Richard is new to the company but not new to the industry, starting with 3DLabs many years ago and taking jobs at NVIDIA, ATI, Intel and now returning to AMD. The role of Gaming Scientist is to directly interface with the software developers for gaming and make sure that the GPU hardware designers are working hand in hand with future, high end graphics technology. In essence, Huddy's job is to make sure AMD continues to innovate on the hardware side to facilitate innovation on the software side.

AMD Planning an "OpenWorks" Program

(33:00) After the volume of discussion surrounding the NVIDIA GameWorks program and its potential to harm the gaming ecosystem by not providing source code in an open manner, Huddy believes that the answer to problem is to simply have NVIDIA release the SDK with source code publicly. Whether or not NVIDIA takes that advice has yet to be seen, but if they don't, it appears that AMD is going down the road of creating its own competing solution that is open and flexible.

The idea of OpenFX or OpenWorks as Huddy refers to it is to create an open source repository for gaming code and effects examples that can be updated, modified and improved upon by anyone in the industry. AMD would be willing to start the initiative by donating its entire SDK to the platform and then invite other software developers, as well as other hardware developers, to add or change to the collection. The idea is to create a competitor to what GameWorks accomplishes but in a license free and open way.

gameworks.jpg

NVIDIA GameWorks has been successful; can AMD OpenWorks derail it?

Essentially the "OpenWorks" repository would work in a similar way to a Linux group where the public has access to the code to submit changes that can be implemented by anyone else. Someone would be able to improve the performance for specific hardware easily but if performance was degraded on any other hardware then it could be easily changed and updated. Huddy believes this is how you move the industry forward and how you ensure that the gamer is getting the best overall experience regardless of the specific platform they are using.

"OpenWorks" is still in the planning stages and AMD is only officially "talking about it" internally. However, bringing Huddy back to AMD wasn't done without some direction already in mind and it would not surprise me at all if this was essentially a done deal. Huddy believes that other hardware companies like Qualcomm and Intel would participate in such an open system but the real question is whether or not NVIDIA, as the discrete GPU market share leader, would be in any way willing to do as well.

Still, this initiative continues to show the differences between the NVIDIA and AMD style of doing things. NVIDIA prefers a more closed system that it has full control over to perfect the experience, to hit aggressive timelines and to improve the ecosystem as they see it. AMD wants to provide an open system that everyone can participate in and benefit from but often is held back by the inconsistent speed of the community and partners. 

Mantle to be Opened by end of 2014, Potentially Coming to Linux

(7:40) The AMD Mantle API has been an industry changing product, I don't think anyone can deny that. Even if you don't own AMD hardware or don't play any of the games currently shipping with Mantle support, the re-focusing on a higher efficiency API has impacted NVIDIA's direction with DX11, Microsoft's plans for DX12 and perhaps even Apple's direction with Metal. But for a company that pushes the idea of open standards so heavily, AMD has yet to offer up Mantle source code in a similar fashion to its standard SDK. As it stands right now, Mantle is only given to a group of software developers in the beta program and is specifically tuned for AMD's GCN graphics hardware.

mantlepic.jpg

Huddy reiterated that AMD has made a commitment to release a public SDK for Mantle by the end of 2014 which would allow any other hardware vendor to create a driver that could run Mantle game titles. If AMD lives up to its word and releases the full source code for it, then in theory, NVIDIA could offer support for Mantle games on GeForce hardware, Intel could offer support those same games on Intel HD graphics. There will be no license fees, no restrictions at all.

The obvious question is whether or not any other IHV would choose to do so. Both because of competitive reasons and with the proximity of DX12's release in late 2015. Huddy agrees with me that the pride of these other hardware vendors may prevent them from considering Mantle adoption though the argument can be made that the work required to implement it properly might not be worth the effort with DX12 (and its very similar feature set) around the corner.

(51:45) When asked about AMD input on SteamOS and its commitment to the gamers that see that as the future, Huddy mentioned that AMD was considering, but not promising, bringing the Mantle API to Linux. If the opportunity exists, says Huddy, to give the gamer a better experience on that platform with the help of Mantle, and developers ask for the support for AMD, then AMD will at the very least "listen to that." It would incredibly interesting to see a competitor API in the landscape of Linux where OpenGL is essentially the only game in town. 

AMD FreeSync / Adaptive Sync Benefits

(59:15) Huddy discussed the differences, as he sees it, between NVIDIA's G-Sync technology and the AMD option called FreeSync but now officially called Adaptive Sync as part of the DisplayPort 1.2a standard. Beside the obvious difference of added hardware and licensing costs, Adaptive Sync is apparently going to be easier to implement as the maximum and minimum frequencies are actually negotiated by the display and the graphics card when the monitor is plugged in. G-Sync requires a white list in the NVIDIA driver to work today and as long as NVIDIA keeps that list updated, the impact on gamers buying panels should be minimal. But with DP 1.2a and properly implemented Adaptive Sync monitors, once a driver supports the negotiation it doesn't require knowledge about the specific model beforehand.

freesync1.jpg

AMD demos FreeSync at Computex 2014

According to Huddy, the new Adaptive Sync specification will go up to as high as 240 Hz and as low as 9 Hz; these are specifics that before today weren't known. Of course, not every panel (and maybe no panel) will support that extreme of a range for variable frame rate technology, but this leaves a lot of potential for improved panel development in the years to come. More likely you'll see Adaptive Sync ready display listing a range closer to 30-60 Hz or 30-80 Hz initially. 

Prototypes of FreeSync monitors will be going out to some media in the September or October time frame, while public availability will likely occur in the January or February window. 

How does AMD pick game titles for the Never Settle program?

(1:14:00) Huddy describes the fashion in which games are vetted for inclusion in the AMD Never Settle program. The company looks for games that have a good history of course, but also ones that exemplify the use of AMD hardware. Games that benchmark well and have reproducible results that can be reported by AMD and the media are also preferred. Inclusion of an integrated benchmark mode in the game is also a plus as it more likely gets review media interested in including that game in their test suite and also allows the public to run their own tests to compare results. 

Another interesting note was the games that are included in bundles often are picked based on restrictions in certain countries. Germany, for example, has very strict guidelines for violence in games and thus add-in card partners would much prefer a well known racing game than an ultra-bloody first person shooter. 

Closing Thoughts

First and foremost, a huge thanks to Richard Huddy for making time to stop by the offices and talk with us. And especially for allowing us to live stream it to our fans and readers. I have had the privilege to have access to some of the most interesting minds in the industry, but they are very rarely open to having our talks broadcast to the world without editing and without a precompiled list of questions. For allowing it, both AMD and Mr. Huddy have gained some respect! 

There is plenty more discussed in the interview including AMD's push to a non-PC based revenue split, whether DX12 will undermine the use of the Mantle API, and how code like TressFX compares to NVIDIA GameWorks. If you haven't watched it yet I think you'll find the full 90 minutes to be quite informative and worth your time.

UPDATE: I know that some of our readers, and some contacts and NVIDIA, took note of Huddy's comments about TressFX from our interview. Essentially, NVIDIA denied that TressFX was actually made available before the release of Tomb Raider. When I asked AMD for clarification, Richard Huddy provided me with the following statement.

I would like to take the opportunity to correct a false impression that I inadvertently created during the interview.

Contrary to what I said, it turns out that TressFX was first published in AMD's SDK _after_ the release of Tomb Raider.

Nonetheless the full source code to TressFX was available to the developer throughout, and we also know that the game was available to NVIDIA several weeks ahead of the actual release for NVIDIA to address the bugs in their driver and to optimize for TressFX.

Again, I apologize for the mistake.

That definitely paints a little bit of a different picture on around the release of TressFX with the rebooted Tomb Raider title. NVIDIA's complaint that "AMD was doing the same thing" holds a bit more weight. Since Richard Huddy was not with AMD at the time of this arrangement I can see how he would mix up the specifics, even after getting briefed by other staff members.

Lightning Returns

With the GPU landscape mostly settled for 2014, we have the ability to really dig in and evaluate the retail models that continue to pop up from NVIDIA and AMD board partners. One of our favorite series of graphics cards over the years comes from MSI in the form of the Lightning brand. These cards tend to take the engineering levels to a point other designers simply won't do - and we love it! Obviously the target of this capability is additional overclocking headroom and stability, but what if the GPU target has issues scaling already?

That is more or less the premise of the Radeon R9 290X Lightning from MSI. AMD's Radeon R9 290X Hawaii GPU is definitely a hot and power hungry part and that caused quite a few issues at the initial release. Since then though, both AMD and its add-in card partners have worked to improve the coolers installed on these cards to improve performance reliability and decrease the LOUD NOISES produced by the stock, reference cooler.

Let's dive into the latest to hit our test bench, the MSI Radeon R9 290X Lightning.

The MSI Radeon R9 290X Lightning

IMG_9897.JPG

MSI continues to utilize the yellow and black color scheme that many of the company's high end parts integrate and I love the combination. I know that both NVIDIA and AMD disapprove of the distinct lack of "green" and "red" in the cooler and box designs, but good on MSI for sticking to its own thing. 

IMG_9900.JPG

The box for the Lightning card is equal to the prominence of the card itself and you even get a nifty drawer for all of the included accessories.

IMG_9901.JPG

We originally spotted the MSI R9 290X Lightning at CES in January and the design remains the same. The cooler is quite large (and damn heavy) and is cooled by a set of three fans. The yellow fan in the center is smaller and spins a bit faster, creating more noise than I would prefer. All fan speeds can be adjusted with MSI's included fan control software.

Computex 2014: ASUS Announces ROG ARES III Water-Cooled Gaming Graphics Card

Subject: Graphics Cards | June 2, 2014 - 11:41 PM |

The latest installment in the ASUS ARES series of ultra-powerful, limited-edition graphics cards has been announced, and the Ares III is set to be the “world’s fastest” video card.

IMG_20140602_190930.jpg

The ARES III features a full EK water block

The dual-GPU powerhouse is driven by two “hand-selected” Radeon Hawaii XT GPUs (R9 290X cores) with 8GB of GDDR5 memory. The card is overclockable according to ASUS, and will likely arrive factory overclocked as they claim it will be faster out of the box than the reference R9-295x2. The ARES III features a custom-designed EK water block, so unlike the R9 295x2 the end user will need to supply the liquid cooling loop.

ASUS claims that the ARES III will “deliver 25% cooler performance than reference R9 295X designs“, but to achieve this ASUS “highly” recommends a high flow rate loop with at least a 120x3 radiator “to extract maximum performance from the card,” and they “will provide a recommended list of water cooling systems at launch”.

Only 500 of the ARES III will be made, and are individually numbered. No pricing has been announced, but ASUS says to expect it to be more than a 295x2 ($1499) - but less than a TITAN Z ($2999). The ASUS ROG ARES III will be available in Q3 2014.
