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.
AMD is up to some interesting things. Today at AMD’s tech day, we discovered a veritable cornucopia of information. Some of it was pretty interesting (audio), some was discussed ad-naseum (audio, audio, and more audio), and one thing in particular was quite shocking. Mantle was the final, big subject that AMD was willing to discuss. Many assumed that the R9 290X would be the primary focus of this talk, but in fact it very much was an aside that was not discussed at any length. AMD basically said, “Yes, the card exists, and it has some new features that we are not going to really go over at this time.” Mantle, as a technology, is at the same time a logical step as well as an unforeseen one. So what all does Mantle mean for users?
Looking back through the mists of time, when dinosaurs roamed the earth, the individual 3D chip makers all implemented low level APIs that allowed programmers to get closer to the silicon than what other APIs such as Direct3D and OpenGL would allow. This was a very efficient way of doing things in terms of graphics performance. It was an inefficient way to do things for a developer writing code for multiple APIs. Microsoft and the Kronos Group had solutions with Direct3D and OpenGL that allowed these programmers to develop for these high level APIs very simply (comparatively so). The developers could write code that would run D3D/OpenGL, and the graphics chip manufacturers would write drivers that would interface with Direct3D/OpenGL, which then go through a hardware abstraction layer to communicate with the hardware. The onus was then on the graphics people to create solid, high performance drivers that would work well with DirectX or OpenGL, so the game developer would not have to code directly for a multitude of current and older graphics cards.

The next generation of AMD graphics processors are being announced this afternoon. They carefully mentioned this event is not a launch. We do not yet know, although I hope we will learn today, when you can give them your money.
When you can, you will have five products to choose from:
- R7 250
- R7 260X
- R9 270X
- R9 280X
- R9 290X
AMD only provides 3D Mark Fire Strike scores for performance. I assume they are using the final score, and not the "graphics score" although they were unclear.
The R7 250 is the low end card of the group with 1GB of GDDR5. Performance, according to 3DMark scores (>2000 on Fire Strike), is expected to be about two-thirds of what an NVIDIA GeForce GTX 650 Ti can deliver. Then again, that card retails for about ~$130 USD. The R7 250 has an expected retail value of less than < $89 USD. This is a pretty decent offering which can probably play Battlefield 3 at 1080p if you play with the graphics quality settings somewhere around "medium". This is just my estimate, of course.
The R7 260X is the next level up. The RAM has been double over the R7 250 to 2GB of GDDR5 and its 3DMark score almost doubled, too (> 3700 on Fire Strike). This puts it almost smack dab atop the Radeon HD 6970. The R7 260X is about $20-30 USD cheaper than the HD 6970. The R7 is expected to retail for $139. Good price cut while keeping up to date on architecture.
The R9 270X is the low end of the high end parts. With 2GB of GDDR5 and a 3DMark Fire Strike score of >5500, this is aimed at the GeForce 670. The R7 270X will retail for around ~$199 which is about $120 USD cheaper than NVIDIA's offering.
The R9 280X should be pretty close to the 7970 GHz Edition. It will be about ~$90 cheaper with an expected retail value of $299. It also has a bump in frame buffer over the lower-tier R9 270X, containing 3GB of GDDR5.
Not a lot is known about the top end, R9 290X, except that it will be the first gaming GPU to cross 5 TeraFLOPs of compute performance. To put that into comparison, the GeForce Titan has a theoretical maximum of 4.5 TeraFLOPs.
If you are interested in the R9 290X and Battlefield 4, you will be able to pre-order a limited edition package containing both products. Pre-orders open "from select partners" October 3rd. For how much? Who knows.
We will keep you informed as we are informed. Also, the announcement is still going on, so tune in!

Back on September 23, 2003 a site called AMDMB did a review of the Athlon 64 FX-51 processor, which turned out to be the fastest desktop processor on the planet at the time and could handily beat Intel's offerings even with their higher clock. As Slashdot has pointed out that this is indeed the 10th year anniversary of the release of that processor they thought it would be nice to look back on a better time in AMD's history. Head to Slashdot to read through the comments and click through to ExtremeTech who have put together a retrospective.
"It's been a decade since AMD's Athlon 64 FX-51 debuted — and launched the 64-bit x86 extensions that power the desktop and laptop world today. After a year of being bludgeoned by the P4, AMD roared back with a vengeance, kicking off a brief golden age for its own products, and seizing significant market share in desktops and servers."
