The Tech Report has been thinking on the upcoming release of SteamOS and AMD's Mantle and they see some problems that could come about because of them. Fragmentation has always been a problem for PCs, be it that the hardware between systems never matches or the wide variety of APIs and game engines on the software side. It can de daunting to begin developing a game and determining if optimizing for AMD, NVIDIA or Intel is worth considering as well as the choice between Direct3D or OpenGL or trying to make them both work. Mantle is now a choice, BF4 will actually be releasing a version that is natively Mantle shortly after they launch the first version of the game. Valve has also hinted that several AAA titles will be released on SteamOS, not necessarily Windows or Linux. What effect could this have on PC gaming as these new choices arrive at the same time the next generation consoles are released? Read on and see.
"Valve's SteamOS and AMD's Mantle API have the potential to do great things for PC gaming. However, they also threaten to fragment the platform at a critical time, when next-gen consoles are about to reduce the PC's performance and image quality lead by a long shot."

This should be little-to-no surprise for the viewers of our podcast, as this story was discussed there, but Valve has confirmed AMD and Intel graphics are compatible with Steam Machines. Doug Lombardi of Valve commented by email to, apparently, multiple sources including Forbes and Maximum PC.
Last week, we posted some technical specs of our first wave of Steam Machine prototypes. Although the graphics hardware that we've selected for the first wave of prototypes is a variety of NVIDIA cards, that is not an indication that Steam Machines are NVIDIA-only. In 2014, there will be Steam Machines commercially available with graphics hardware made by AMD, NVIDIA, and Intel. Valve has worked closely together with all three of these companies on optimizing their hardware for SteamOS, and will continue to do so into the foreseeable future.
Ryan and the rest of the podcast crew found the whole situation, "Odd". They could not understand why AMD referred the press to Doug Lombardi rather than circulate a canned statement from him. It was also weird why NVIDIA had an exclusive on the beta program with AMD being commercially available in 2014.
As I have said in the initial post: for what seems to be deliberate non-committal to a specific hardware spec, why limit to a single graphics provider?

DigiTimes has broken the news that NVIDIA will be cutting prices on many of their cards in reaction to AMD's new GPU family. Currently the lowest priced GTX660 is $150 after MIR and a GTX650Ti Boost can be had for $110. We don't have any information as to how they will be updating the GTX 760, likely faster clocks but we can hope for something a little more adventurous. The GTX 760 can be had for $250 right now but you should hold off to see what the new model has and what it does to the price of the current model.
"Nvidia has offered price cuts for several of its graphics cards including the GTX 660 and GTX 650Ti Boost and will soon release an upgraded GTX 760, targeting AMD's Radeon R9 280X, according to sources from graphics card makers."

Verizon is launching its new public cloud later this year and offering both compute and storage to enterprise customers. The Verizon Cloud Compute and Cloud Storage products will be hosted on AMD SM15000 servers in a multi-rack cluster built by Verizon-owned Terremark.
The new cloud service is powered by AMD SM15000 servers with are 10U units with multiple microservers interconnected by SeaMicro's Freedom Fabric technology. Verizon is aiming the new cloud service at business users, from SMBs to fortune 500 companies. Specifically, Verizon is hoping to entice IT departments to offload internal company applications and services to the Verizon Cloud Compute and Cloud Storage offerings. Using the SeaMicro-built (now owned by AMD) servers, Verizon has a high density, efficient infrastructure that can allegedly provision and deploy virtual machines with fine tuned specifications and performance and reliability backed by enterprise-level SLAs while being compliant with PCI and DoD standards for data security.
Verizon will be launching Cloud Compute and Cloud Storage as a public beta in Q4 of this year. Further, the company will be taking on beta customers later this month.
The AMD SM15000 is a high performance, high density server, and is an interesting product for cloud services thanks to the networking interconnects and power efficient compute cards. Verizon and AMD have been working together for the better part of two years on the cloud platform using the servers which were first launched to the public a little more than a year ago.
The SM15000 is a 10U server that is actually made up of multiple compute cards. AMD and SeaMicro also pack the server with a low latency and high bandwidth networking fabric to connect the servers to each other, multiple power supplies, and the ability to connect to a shared pool of storage that each compute card can access. Each compute card uses a small, cut down motherboard, processor, ram, and networking IO. The processors can be AMD Opteron, Intel Xeon, or Intel Atom with the future possibility of an AMD APU-based server (which is the configuration option that I am most interested in). In this case, Verizon appears to be using AMD Opteron chips, which means each compute card has a single eight core AMD Opteron CPU clocked at up to 2.8GHz, 64GB of system memory, and a 10Gbps networking link.
In total, each SM15000 server is powered by 512 CPU cores, up to 4TB of RAM, ten 1,100W PSUs, and support for more than 5PB of shared storage. Considering Verizon is using multiple racks filled with SM15000 servers, there is a lot of hardware on offer to support a multitude of mission critical applications backed by SLAs (service level agreements, which are basically guarantees of uptime and/or performance).
I'm looking forward to seeing what sorts of things customers end up doing with the Verizon Cloud and how the SeaMicro-built servers hold up once the service is fully ramped up and utilized.
You can find more information on the SM15000 servers in my article on their initial debut. Also, the full press release on the Verizon Cloud is below.

Rebranding existing hardware with fancy new model numbers is nothing new to either AMD or NVIDA. Review sites catch on immediately and while we like to see optimizations applied to mature chips we much prefer brand new hardware. When you release the Q-1200000 as the X-2200000 the best you will get from review sites is a recommendation to go with the model that has the lower price, not the higher model number. Most enthusiasts have caught on to the fact that they are the same product; we do not like it but we have come to accept it as common business practice. Certain unintentional consequences from designs we can forgive as long as you admit the issue and work to rectify it, only the intentional limitations are being mentioned in this post.
This is where the problem comes in as it seems that this intentional misleading of customers has created a mindset where it is believed that it is OK to intentionally impose performance limitations on products. Somehow companies have convinced themselves that a customer base who routinely tears apart hardware, uses scanners to see inside actual components and who write their own OSes from scratch (or at least update the kernel) will somehow not be able to discover these limitations. Thus we have yesterday's revelation that NVIDIA has artificially limited the number of screens usable in Linux to three; not because of performance or stability issues but simply because it might provide Linux users with a better experience that Windows users.
Apparently AMD is not to be outdone when it comes to this kind of dirty pool, in their case it is audio that is limited as opposed to video. If you are so uncouth as to use a DVI to HDMI adapter which did not come with your shiny new Radeon then you are not allowed to have audio signals transferred over that HDMI cable on either Windows or Linux. There is a ... shall we say Apple-like hardware check, that Phoronix reported on which will disable the audio output unless a specific EEPROM on your adapter is detected. NVIDIA doesn't sell monitors nor is AMD really in the dongle business but apparently they are willing to police the components you choose to use, though the causes of AMD's decision are not as clear as NVIDIA's for as far as we know Monster Cable does not have the magic EEPROM in their adapters.
If your customers are as talented as your engineers you might not want to listen to your salespeople who tell you that partnerships with other companies are more important than antagonizing your customers by trying to pull a fast one on them. We will find out and it will come back to haunt you. Unless the payoffs you get from your partnerships are more than you make selling to customers in which case you might as well just ignore us.
"For some AMD Radeon graphics cards when using the Catalyst driver, the HDMI audio support isn't enabled unless using the simple DVI to HDMI adapter included with the graphics card itself... If you use another DVI-to-HDMI adapter, it won't work with Catalyst. AMD intentionally implemented checks within their closed-source driver to prevent other adapters from being used, even though they will work just fine."

AMD's rebranded cards have arrived, though with a few improvements to the GCN architecture that we already know so well. This particular release seems to be focused on price for performance which is certainly not a bad thing in these uncertain times. The 7970 GHz Edition launched at $500, while the new R9 280X will arrive at $300 which is a rather significant price drop and one which we hope doesn't damage AMD's bottom line too badly in the coming quarters. [H]ard|OCP chose the ASUS R9 280X DirectCU II TOP to test, with a custom PCB from ASUS and a mild overclock which helped it pull ahead of the 7970 GHz. AMD has tended towards leading off new graphics card families with the low and midrange models, we have yet to see the top of the line R9 290X in action yet.
Ryan's review, including frame pacing, can be found right here.
"We evaluate the new ASUS R9 280X DirectCU II TOP video card and compare it to GeForce GTX 770 and Radeon HD 7970 GHz Edition. We will find out which video card provides the best value and performance in the $300 price segment. Does it provide better performance a than its "competition" in the ~$400 price range?"

The AMD Radeon R9 280X
Today marks the first step in an introduction of an entire AMD Radeon discrete graphics product stack revamp. Between now and the end of 2013, AMD will completely cycle out Radeon HD 7000 cards and replace them with a new branding scheme. The "HD" branding is on its way out and it makes sense. Consumers have moved on to UHD and WQXGA display standards; HD is no longer extraordinary.
But I want to be very clear and upfront with you: today is not the day that you’ll learn about the new Hawaii GPU that AMD promised would dominate the performance per dollar metrics for enthusiasts. The Radeon R9 290X will be a little bit down the road. Instead, today’s review will look at three other Radeon products: the R9 280X, the R9 270X and the R7 260X. None of these products are really “new”, though, and instead must be considered rebrands or repositionings.
There are some changes to discuss with each of these products, including clock speeds and more importantly, pricing. Some are specific to a certain model, others are more universal (such as updated Eyefinity display support).
Let’s start with the R9 280X.
AMD Radeon R9 280X – Tahiti aging gracefully
The AMD Radeon R9 280X is built from the exact same ASIC (chip) that powers the previous Radeon HD 7970 GHz Edition with a few modest changes. The core clock speed of the R9 280X is actually a little bit lower at reference rates than the Radeon HD 7970 GHz Edition by about 50 MHz. The R9 280X GPU will hit a 1.0 GHz rate while the previous model was reaching 1.05 GHz; not much a change but an interesting decision to be made for sure.
Because of that speed difference the R9 280X has a lower peak compute capability of 4.1 TFLOPS compared to the 4.3 TFLOPS of the 7970 GHz. The memory clock speed is the same (6.0 Gbps) and the board power is the same, with a typical peak of 250 watts.
Everything else remains the same as you know it on the HD 7970 cards. There are 2048 stream processors in the Tahiti version of AMD’s GCN (Graphics Core Next), 128 texture units and 32 ROPs all being pushed by a 384-bit GDDR5 memory bus running at 6.0 GHz. Yep, still with a 3GB frame buffer.

Last week, NVIDIA published documentation for Nouveau to heal wounds with the open source community. AMD had a better reputation and intends to maintain it. On Tuesday, Alex Deucher published 9 PDF documents, 1178 pages of register and acceleration documentation along with 18 pages of HDA GPU audio programming details, compared to the 42 pages NVIDIA published.
Sure, a page to page comparison is meaningless, but it is clear AMD did not want to be outdone. This is especially true when you consider that some of these documents date back to early 2009. Still, reactionary or not, the open source community should accept the assistance with open arms... and open x86s?
I should note that these documents do not cover Volcanic Islands; they are for everything between Evergreen and Sea Islands.

Scott Wasson of The Tech Report just received an interview with Raja Koduri, head of Graphics Hardware and Software Development at AMD, a few hours ago. Part of the interview discussed frame the frame pacing issues we, as well as The Tech Report, published over the last year. In short, the news seems good for owners of Radeon graphics cards, future and even current.
The "Hawaii" powered Radeon R9 290 and R9 290X graphics cards are expected to handle CrossFire pacing acceptably at launch. Clearly, if there is ever a time to fix the problem, it would be in new hardware. Still, this is good news for interested customers; if all goes to plan, you are likely going to have a good experience out of the box.
Current owners of GCN-based video cards, along with potential buyers of the R9 280X and lower upcoming cards, will apparently need to wait for AMD to release a driver to fix these issues. However, this driver is not far off: Koduri, unclear whether on or off the record, intends for an autumn release. This driver is expected to cover frame pacing issues for CrossFire, Eyefinity, and 4K.
Koduri does believe the CrossFire issues were unfortunate and expresses a desire to fix the issue for his customers.
Keep checking PC Perspective for more information as it comes out!
Editor's Note: I just spoke with Raja Koduri as well and he basically reiterated everything that Scott noted in his story on The Tech Report as well. The upcoming 290X will have frame pacing at Eyefinity and 4K resolution at launch while the cards below that in the R9 series, and users of Radeon HD 7000 cards (and likely beyond) will need some more time before the driver is ready. I'll be able to talk quite a bit more about the changes to BOTH architectures very shortly so stay tuned for that.
