Hawaii launches and AMD sells their inventory (all of it, in many cases). The Radeon R9 290X brought reasonably Titan-approaching performance to the $550-600 USD dollar value. Near and dear to our website, AMD also took the opportunity to address much of the Crossfire and Eyefinity frame pacing issues.
Nitroware also took a look at the card... from a distance because they did not receive a review unit. His analysis was based on concepts, such as revisions to AMD design over the life of their Graphics Core Next architecture. The discussion goes back to the ATI Rage series of fixed function hardware and ends with a comparisson between the Radeon HD 7900 "Tahiti" and the R9 290X "Hawaii".
Our international viewers (or even curious North Americans) might also like to check out the work Dominic undertook compiling regional pricing and comparing those values to currency conversion data. There is more to an overview (or review) than benchmarks.

A lot of news coming from the NVIDIA camp today, including some price drops and price announcements.
First up, the high-powered GeForce GTX 780 is getting dropped from $649 to $499, a $150 savings that will bring the GTX 780 into line with the competition of AMD's new Radeon R9 290X launched last week.
Next, the GeForce GTX 770 2GB is going to drop from $399 to $329 to help it compete more closely with the R9 280X.
Even you weren't excited about the R9 290X, you have to be excited by competition.
In a surprising turn of events, NVIDIA is now the company with the great bundle deal with GPUs as well! Starting today you'll be able to get a free copy of Batman: Arkham Origins, Splinter Cell: Blacklist and Assassin's Creed IV: Black Flag with the GeForce GTX 780 Ti, GTX 780 and GTX 770. If you step down to the GTX 760 or 660 you'll lose out on the Batman title.
SHIELD discounts are available as well: $100 off you buy the upper tier GPUs and $50 off if you but the lower tier.
UPDATE: NVIDIA just released a new version of GeForce Experience that enabled ShadowPlay, the ability to use Kepler GPUs to record game play in the background with almost no CPU/system ovehead. You can see Scott's initial impressions of the software right here; it seems like its going to be a pretty awesome feature.
Need more news? The yet-to-be-released GeForce GTX 780 Ti is also getting a price - $699 based on the email we just received. And it will be available starting November 7th!!
With all of this news, how does it change our stance on the graphics market? Quite a bit in fact. The huge price drop on the GTX 780, coupled with the 3-game bundle means that NVIDIA is likely offering the better hardware/software combo for gamers this fall. Yes, the R9 290X is likely still a step faster, but now you can get the GTX 780, three great games and spend $50 less.
The GTX 770 is now poised to make a case for itself against the R9 280X as well with its $70 drop. The R9 280X / HD 7970 GHz Edition was definitely a better option with its $100 price delta but with only $30 separating the two competing cards, and the three free games, again the advantage will likely fall to NVIDIA.
Finally, the price point of the GTX 780 Ti is interesting - if NVIDIA is smart they are pricing it based on comparable performance to the R9 290X from AMD. If that is the case, then we can guess the GTX 780 Ti will be a bit faster than the Hawaii card, while likely being quieter and using less power too. Oh, and again, the three game bundle.
NVIDIA did NOT announce a GTX TITAN price drop which might surprise some people. I think the answer as to why will be addressed with the launch of the GTX 780 Ti next month but from what I was hearing over the last couple of weeks NVIDIA can't make the cards fast enough to satisfy demand so reducing margin there just didn't make sense.
NVIDIA has taken a surprisingly aggressive stance here in the discrete GPU market. The need to address and silence critics that think the GeForce brand is being damaged by the AMD console wins is obviously potent inside the company. The good news for us though, and the gaming community as a whole, is that just means better products and better value for graphics card purchases this holiday.
NVIDIA says these price drops will be live by tomorrow. Enjoy!

If you didn't stay up to watch our live release of the R9 290X after the podcast last night you missed a chance to have your questions answered but you will be able to watch the recording later on. The R9 290X arrived today, bringing 4K and Crossfire reviews as well as single GPU testing on many a site including PCPer of course. You don't just have to take our word for it, [H]ard|OCP was also putting together a review of AMD's Titan killer. Their benchmarks included some games we haven't adopted yet such as ARMA III. Check out their results and compare them to ours, AMD really has a winner here.
"AMD is launching the Radeon R9 290X today. The R9 290X represents AMD's fastest single-GPU video card ever produced. It is priced to be less expensive than the GeForce GTX 780, but packs a punch on the level of GTX TITAN. We look at performance, the two BIOS mode options, and even some 4K gaming."

Currently AMD holds 18% market share with their FirePro line of professional GPUs. This compares to NVIDIA who owns 81% with Quadro. I assume the "other" category is the sum of S3 and Matrox who, together, command 1% of the professional market (just the professional market)
According to Jon Peddie of JPR, as reported by X-Bit Labs, AMD intends to wrestle back revenue left unguarded for NVIDIA. "After years of neglect, AMD’s workstation group, under the tutorage of Matt Skyner, has the backing and commitment of top management and AMD intends to push into the market aggressively." They have already gained share this year.
During AMD's 3rd Quarter (2013) earnings call, CEO Rory Read outlined the importance of the professional graphics market.
We also continue to make steady progress in another of growth businesses in the third quarter as we delivered our fifth consecutive quarter of revenue and share growth in the professional graphics area. We believe that we can continue to gain share in this lucrative part of the GPU market based on our product portfolio, design wins in flight, and enhanced channel programs.
On the same conference call (actually before and after the professional graphics sound bite), Rory noted their renewed push into the server and embedded SoC markets with 64-bit x86 and 64-bit ARM processors. They will be the only company manufacturing both x86 and ARM solutions which should be an interesting proposition for an enterprise in need of both. Why deal with two vendors?
Either way, AMD will probably be refocusing on the professional and enterprise markets for the near future. For the rest of us, this hopefully means that AMD has a stable (and confident) roadmap in the processor and gaming markets. If that is the case, a profitable Q3 is definitely a good start.

Having already seen what the ASUS R9 280X DirectCU II TOP can do at default speeds the obvious next step, once they had time to fully explore the options, was for [H]ard|OCP to see just how far this GPU can overclock. To make a long story short, they went from a default clock of 1070MHz up to 1230MHz and pushed the RAM to 6.6GHz from 6.4GHz though the voltage needed to be bumped from 1.2v to 1.3v. The actual frequencies are nowhere near as important as the effect on gameplay though, to see those results you will have to click through to the full article.
"We take the new ASUS R9 280X DirectCU II TOP video card and find out how high it will overclock with GPU Tweak and voltage modification. We will compare performance to an overclocked GeForce GTX 770 and find out which card comes out on top when pushed to its overclocking limits."

Mid-June kicked up a storm of poop across the internet when IGN broke the AMD optimizations for Frostbite 3. It was reported that NVIDIA would not receive sample code for those games until after they launched. The article was later updated with a statement from AMD: "... the AMD Gaming Evolved program undertakes no efforts to prevent our competition from optimizing for games before their release."
Now, I assume, the confusion was caused by then-not-announced Mantle.
And, as it turns out, NVIDIA did receive the code for Battlefield 4 prior to launch. Monday, the company launched their 331.58 WHQL-certified drivers which are optimized for Batman: Arkham Origins and Battlefield 4. According to the release notes, you should even be able to use SLi out of the gate. If, on the other hand, you are a Civilization V player: HBAO+ should enhance your shadowing.
They also added a DX11 SLi profile for Watch Dogs... awkwarrrrrd.
To check out the blog at GeForce.com for a bit more information, check out the release notes, or just head over to the drivers page. If you have GeForce Experience installed, it probably already asked you to update.

UPDATE: If you missed our live stream today that covered NVIDIA G-Sync technology, you can watch the replay embedded below. NVIDIA's Tom Petersen stops by to talk about G-Sync in both high level and granular detail while showing off some demonstrations of why G-Sync is so important. Enjoy!!
Last week NVIDIA hosted press and developers in Montreal to discuss a couple of new technologies, the most impressive of which was NVIDIA G-Sync, a new monitor solution that looks to solve the eternal debate of smoothness against latency. If you haven't read about G-Sync and how impressive it was when first tested on Friday, you should check out my initial write up, NVIDIA G-Sync: Death of the Refresh Rate, that not only does that, but dives into the reason the technology shift was necessary in the first place.
G-Sync essentially functions by altering and controlling the vBlank signal sent to the monitor. In a normal configuration, vBlank is a combination of the combination of the vertical front and back porch and the necessary sync time. That timing is set a fixed stepping that determines the effective refresh rate of the monitor; 60 Hz, 120 Hz, etc. What NVIDIA will now do in the driver and firmware is lengthen or shorten the vBlank signal as desired and will send it when one of two criteria is met.
- A new frame has completed rendering and has been copied to the front buffer. Sending vBlank at this time will tell the screen grab data from the card and display it immediately.
- A substantial amount of time has passed and the currently displayed image needs to be refreshed to avoid brightness variation.
In current display timing setups, the submission of the vBlank signal has been completely independent from the rendering pipeline. The result was varying frame latency and either horizontal tearing or fixed refresh frame rates. With NVIDIA G-Sync creating an intelligent connection between rendering and frame updating, the display of PC games is fundamentally changed.
Every person that saw the technology, including other media members and even developers like John Carmack, Johan Andersson and Tim Sweeney, came away knowing that this was the future of PC gaming. (If you didn't see the panel that featured those three developers on stage, you are missing out.)
But it is definitely a complicated technology and I have already seen a lot of confusion about it in our comment threads on PC Perspective. To help the community get a better grasp and to offer them an opportunity to ask some questions, NVIDIA's Tom Petersen is stopping by our offices on Monday afternoon where he will run through some demonstrations and take questions from the live streaming audience.
Be sure to stop back at PC Perspective on Monday, October 21st at 2pm ET / 11am PT as to discuss G-Sync, how it was developed and the various ramifications the technology will have in PC gaming. You'll find it all on our PC Perspective Live! page on Monday but you can sign up for our "live stream mailing list" as well to get notified in advance!

11am PT / 2pm ET - October 21st
We also want your questions!! The easiest way to get them answered is to leave them for us here in the comments of this post. That will give us time to filter through the questions and get the answers you need from Tom. We'll take questions via the live chat and via Twitter (follow me @ryanshrout) during the event but often time there is a lot of noise to deal with.

Tagged: nvidia, GeForce GTX 780 Ti
So the really interesting news today was G-Sync but that did not stop NVIDIA from sneaking in a new high-end graphics card. The GeForce GTX 780 Ti follows the company's old method of releasing successful products:
- Attach a seemingly arbitrary suffix to a number
In all seriousness, we know basically nothing about this card. It is entirely possible that its architecture might not even be based on GK110. We do know it will be faster than a GeForce 780 but we have no frame of reference in regards to the GeForce Titan. The two cards were already so close in performance that Ryan struggled to validate the 780's existence. Imagine how difficult it would be for NVIDIA to wedge yet another product in that gap.
And if it does outperform the Titan, what is its purpose? Sure, Titan is a GPGPU powerhouse if you want double-precision performance without purchasing a Tesla or a Quadro, but that is not really relevant for gamers yet.
We shall see, soon, when we get review samples in. You, on the other hand, will likely see more when the card launches mid-November. No word on pricing.

UPDATE: I have posted a more in-depth analysis of the new NVIDIA G-Sync technology: NVIDIA G-Sync: Death of the Refres Rate. Thanks for reading!!
UPDATE 2: ASUS has announced the G-Sync enabled version of the VG248QE will be priced at $399.
During a gaming event being held in Montreal, NVIDIA unveield a new technology for GeForce gamers that the company is hoping will revolutionize the PC and displays. Called NVIDIA G-Sync, this new feature will combine changes to the graphics driver as well as change to the monitor to alter the way refresh rates and Vsync have worked for decades.
With standard LCD monitors gamers are forced to choose between a tear-free experience by enabling Vsync or playing a game with the substantial visual anomolies in order to get the best and most efficient frame rates. G-Sync changes that by allowing a monitor to display refresh rates other than 60 Hz, 120 Hz or 144 Hz, etc. without the horizontal tearing normally associated with turning off Vsync. Essentially, G-Sync allows a properly equiped monitor to run at a variable refresh rate which will improve the experience of gaming in interesting ways.
This technology will be available soon on Kepler-based GeForce graphics cards but will require a monitor with support for G-Sync; not just any display will work. The first launch monitor is a variation on the very popular 144 Hz ASUS VG248QE 1920x1080 display and as we saw with 3D Vision, supporting G-Sync will require licensing and hardware changes. In fact, NVIDIA claims that the new logic inside the panels controller is NVIDIA's own design - so you can obviously expect this to only function with NVIDIA GPUs.
DisplayPort is the only input option currently supported.
It turns out NVIDIA will actually be offering retrofitting kits for current users of the VG248QE at some yet to be disclosed cost. The first retail sales of G-Sync will ship as a monitor + retrofit kit as production was just a bit behind.
Using a monitor with a variable refresh rates allows the game to display 55 FPS on the panel at 55 Hz without any horizontal tearing. It can also display 133 FPS at 133 Hz without tearing. Anything below the 144 Hz maximum refresh rate of this monitor will be running at full speed without the tearing associated with the lack of vertical sync.
The technology that NVIDIA is showing here is impressive when seen in person; and that is really the only way to understand the difference. High speed cameras and captures will help but much like 3D Vision was, this is a feature that needs to be seen to be appreciated. How users will react to that road block will have to be seen.
Features like G-Sync show the gaming world that without the restrictions of console there is quite a bit of revolutionary steps that can be made to maintain the PC gaming advantage well into the future. 4K displays were a recent example and now NVIDIA G-Sync adds to the list.
Be sure to stop back at PC Perspective on Monday, November 21st at 2pm ET / 11am PT as we will be joined in-studio by NVIDIA's Tom Petersen to discuss G-Sync, how it was developed and the various ramifications the technology will have in PC gaming.

Tagged: nvidia, GTX 760 OEM
A pair of new graphics cards have been announced during the first day of "The Way It's Meant To Be Played Montreal 2013" both of which intended for system builders to integrate into their products. Both cards fall under the GeForce GTX 760 branding with the names: "GeForce GTX 760 Ti (OEM)" and "GeForce GTX 760 192-bit (OEM)".
I will place the main specifications of both cards side-by-side-side with the default GeForce 760 for a little bit of reference. Be sure to check out its benchmark.
|GTX 760||GTX 760 192-bit (OEM)||GTX 760 Ti (OEM)|
|Base Clock||980 MHz||823 MHz||915 MHz|
|Boost Clock||1033 MHz||888 MHz||980 MHz|
|Memory Bandwidth||6.0 GT/s||5.8 GT/s||6.0 GT/s|
|vRAM (capacity)||2 GB||1.5 or 3 GB||2 GB|
The GeForce 760 is no slouch and, especially the GTX 760 Ti, seems to be pretty close in performance to the retail product. I could see this being a respectible addition to a Steam Machine. I still cannot understand why, like the gaming bundle, these cards were not announced during the keynote speech.
Or, for that matter, why no-one seems to be reporting on them.

Tagged: shield, nvidia, bundle
The live stream from NVIDIA, this morning, was full of technologies focused around the PC gaming ecosystem including mobile (but still PC-like) platforms. Today they also announced a holiday gaming bundle for their GeForce cards although that missed the stream for some reason.
If you purchase a GeForce GTX 770, 780, or Titan from a participating retailer (including online), you will receive Splinter Cell: Black List, Batman: Arkham Origins, and Assassin's Creed IV: Black Flag along with a $100-off coupon for an NVIDIA SHIELD.
If, on the other hand, you purchase a GTX 760, 680, 670, 660 Ti, or 660 from a participating retailer (again, including online), you will receive Splinter Cell: Black List and Assassin's Creed IV: Black Flag along with a $50-off coupon for the NVIDIA SHIELD.
The current price at Newegg for an NVIDIA SHIELD is $299 USD. With a $100 discount, this pushes the price point to $199. The $200 price point is a barrier, for videogame systems, under which customers tend to jump at. Reaching the sub-$200 price point could be a big deal even for customers not on the fence especially when you consider PC streaming. Could be.
Assume you were already planning on upgrading your GPU. Would you be interested in adding in an NVIDIA SHIELD for an extra $199?

Tagged: radeon, R9 290X, amd
The NDA on AMD R9 290X benchmarks has not yet lifted but AMD was in Montreal to provide two previews: BioShock Infinite and Tomb Raider, both at 4K (3840 x 2160). Keep in mind, these scores are provided by AMD and definitely does not represent results from our monitor-capture solution. Expect more detailed results from us, later, as we do some Frame Rating.
The test machine used in both setups contains:
- Intel Core i7-3960X at 3.3 GHz
- MSI X79A-GD65
- 16GB of DDR3-1600
- Windows 7 SP1 64-bit
- NVIDIA GeForce GTX 780 (331.40 drivers) / AMD Radeon R9 290X (13.11 beta drivers)
The R9 290X is configured in its "Quiet Mode" during both benchmarks. This is particularly interesting, to me, as I was unaware of such feature (it has been a while since I last used a desktop AMD/ATi card). I would assume this is a fan and power profile to keep noise levels as silent as possible for some period of time. A quick Google search suggests this feature is new with the Radeon Rx200-series cards.
BioShock Infinite is quite demanding at 4K with ultra quality settings. Both cards maintain an average framerate above 30FPS.
AMD R9 290X "Quiet Mode": 44.25 FPS
NVIDIA GeForce GTX 780: 37.67 FPS
(Update 1: 4:44pm EST) AMD confirmed TressFX is disabled in these benchmark scores. It, however, is enabled if you are present in Montreal to see the booth. (end of update 1)
Tomb Raider is also a little harsh at those resolutions. Unfortunately, the results are ambiguous whether or not TressFX has been enabled throughout the benchmarks. The summary explicitly claims TressFX is enabled, while the string of settings contains "Tressfx=off". Clearly, one of the two entries is a typo. We are currently trying to get clarification. In the mean time:
AMD R9 290X "Quiet Mode": 40.2 FPS
NVIDIA GeForce GTX 780: 34.5 FPS
Notice how both of these results are not compared to a GeForce Titan. Recent leaks suggest a retail price for AMD's flagship card in the low-$700 market. The GeForce 780, on the other hand, resides in the $650-700 USD price point.
It seems pretty clear, to me, that cost drove this comparison rather than performance.

In summary, "We don't know yet".
We do know of a story posted by Fudzilla which cited Roy Taylor, VP of Global Channel Sales, as a source confirming the reintroduction of Never Settle for the new "Rx200" Radeon cards. Adding credibility, Roy Taylor retweeted the story via his official account. This tweet is still there as I write this post.
The Tech Report, after publishing the story, was contacted by Robert Hallock of AMD Gaming and Graphics. The official word, now, is that AMD does not have any announcements regarding bundles for new products. He is also quoted, "We continue to consider Never Settle bundles as a core component of AMD Gaming Evolved program and intend to do them again in the future".
So, I (personally) see promise in that we will see a new Never Settle bundle. For the moment, AMD is officially silent on the matter. Also, we do not know (and, it is possible, neither does AMD at this time) which games will be included and how many users can claim if there will even be a choice at all.

Tagged: FPGA, Altera
(Update 10/17/2013, 6:13 PM) Apparently I messed up inputing this into the website last night. To compare FPGAs with current hardware, the Altera Stratix 10 is rated at more than 10 TeraFLOPs compared to the Tesla K20X at ~4 TeraFLOPs or the GeForce Titan at ~4.5 TeraFLOPs. All figures are single precision. (end of update)
Field Programmable Gate Arrays (FPGAs) are not general purpose processors; they are not designed to perform any random instruction at any random time. If you have a specific set of instructions that you want performed efficiently, you can spend a couple of hours compiling your function(s) to an FPGA which will then be the hardware embodiment of your code.
This is similar to an Application-Specific Integrated Circuit (ASIC) except that, for an ASIC, it is the factory who bakes your application into the hardware. Many (actually, to my knowledge, almost every) FPGAs can even be reprogrammed if you can spare those few hours to configure it again.
Altera is a manufacturer of FPGAs. They are one of the few companies who were allowed access to Intel's 14nm fabrication facilities. Rahul Garg of Anandtech recently published a story which discussed compiling OpenCL kernels to FPGAs using Altera's compiler.
Now this is pretty interesting.
The design of OpenCL splits work between "host" and "kernel". The host application is written in some arbitrary language and follows typical programming techniques. Occasionally, the application will run across a large batch of instructions. A particle simulation, for instance, will require position information to be computed. Rather than having the host code loop through every particle and perform some complex calculation, what happens to each particle could be "a kernel" which the host adds to the queue of some accelerator hardware. Normally, this is a GPU with its thousands of cores chunked into groups of usually 32 or 64 (vendor-specific).
An FPGA, on the other hand, can lock itself to the specific set of instructions. It can decide to, within a few hours, configure some arbitrary number of compute paths and just churn through each kernel call until it is finished. The compiler knows exactly the application it will need to perform while the host code runs on the CPU.
This is obviously designed for enterprise applications, at least as far into the future as we can see. Current models are apparently priced in the thousands of dollars but, as the article points out, has the potential to out-perform a 200W GPU at just a tenth of the power. This could be very interesting for companies, perhaps a film production house, who wants to install accelerator cards for sub-d surfaces or ray tracing but would like to develop the software in-house and occasionally update their code after business hours.
Regardless of the potential market, a FPGA-based add-in card simply makes sense for OpenCL and its architecture.

Microsoft posted a new blog on its Windows site that discusses some of the new features of the latest DirectX on Windows 8.1 and the upcoming Xbox One. Of particular interest was a line that confirms what I have said all along about the much-hyped AMD Mantle low-level API: it is not compatible with Xbox One.
We are very excited that with the launch of Xbox One, we can now bring the latest generation of Direct3D 11 to console. The Xbox One graphics API is “Direct3D 11.x” and the Xbox One hardware provides a superset of Direct3D 11.2 functionality. Other graphics APIs such as OpenGL and AMD’s Mantle are not available on Xbox One.
What does this mean for AMD? Nothing really changes except some of the common online discussion about how easy it would now be for developers to convert games built for the console to the AMD-specific Mantle API. AMD claims that Mantle offers a significant performance advantage over DirectX and OpenGL by giving developers that choose to implement support for it closer access to the hardware without much of the software overhead found in other APIs.
This is what Mantle does. It bypasses DirectX (and possibly the hardware abstraction layer) and developers can program very close to the metal with very little overhead from software. This lowers memory and CPU usage, it decreases latency, and because there are fewer “moving parts” AMD claims that they can do 9x the draw calls with Mantle as compared to DirectX. This is a significant boost in overall efficiency. Before everyone gets too excited, we will not see a 9x improvement in overall performance with every application. A single HD 7790 running in Mantle is not going to power 3 x 1080P monitors in Eyefinity faster than a HD 7970 or GTX 780 (in Surround) running in DirectX. Mantle shifts the bottleneck elsewhere.
I still believe that AMD Mantle could bring interesting benefits to the AMD Radeon graphics cards on the PC but I think this official statement from Microsoft will dampen some of the over excitement.
Also worth noting is this comment about the DX11 implementation on the Xbox One:
With Xbox One we have also made significant enhancements to the implementation of Direct3D 11, especially in the area of runtime overhead. The result is a very streamlined, “close to metal” level of runtime performance. In conjunction with the third generation PIX performance tool for Xbox One, developers can use Direct3D 11 to unlock the full performance potential of the console.
So while Windows and the upcoming Xbox One will share an API there will still be performance advantages for games on the console thanks to the nature of a static hardware configuration.

When you deal with the web, almost nothing is hidden. The browsers (and some extensions) have access to just about everything on screen and off. Anyone browsing a site or app can inspect the contents and even modify it. That last part could be key.
TechPowerUp got their hands on a screenshot of developer tools inspecting the Newegg website. A few elements are hidden on the right hand side within the "Coming Soon" container. One element, id of "singleFinalPrice", is set "visibility: hidden;" with a price as its contents. In the TechPowerUp screenshot, this price is listed as "729.99" USD.
Of course, good journalism is confirming this yourself. As of the time I checked, this value is listed as "9999.99" USD. This means either one of two things: Newegg changed their value to a placeholder after the leak was discovered or the source of TechPowerUp's screenshot used those same developer tools to modify the content. It is actually a remarkably easy thing to do... here I change the value to 99 cents by right clicking on the element and modifying the HTML.
No, the R9 290X is not 99 cents.
So I would be careful to take these screenshots with a grain of salt if we only have access to one source. That said, $729.99 does sound like a reasonable price point for AMD to release a Titan-competitor at. Of course, that is exactly what a hoaxer would want.
But, as it stands right now, I would not get your hopes up. An MSRP of ~$699-$749 USD sounds legitimate but we do not have even a second source, at the moment, to confirm that. Still, this might be something our readers would like to know.

Tagged: amd, nvidia, Intel, Steam Machine
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?

We saw the release of the reference R9s yesterday and today we get to see the custom models such as the Sapphire TOXIC R9 270X which Legit Reviews just finished benchmarking. The TOXIC sports a 100MHz overclock on both GPU and RAM as well as a custom cooler with three fans. While it remains a two slot GPU it is longer than the reference model and requires a full foot of clearance inside the case. Read on to see what kind of performance boost you can expect and how much further you can push this card.
"When it comes to discrete graphics, the $199 price point is known as the gamer’s sweet spot by both AMD and NVIDIA. This is arguably the front line in the battle for your money when it coming to gaming graphics cards. The AMD Radeon R9 270X is AMD’s offering to gamers at this competitive price point. Read on to see how it performs!"
