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.

"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.

A curious new driver from AMD

In case you missed the news, AMD is going to be making a big push with their Radeon brand from now until the end of the year starting with an incredibly strong game bundle that includes as many as three full games and 20% off the new Medal of Honor.  The second part of this campaign is a new driver specifically the 12.11 beta that will be posted to the public later this week.

AMD is claiming to have made some substantial improvements on quite a few games including the very popular Battlefield 3 and the upcoming Medal of Honor (both of which use the same base engine).  But keep in mind that 15% is a LOT and this is the best case scenario in specific maps and you may not see benefits on others. 

There are going to be some debates about the validity of these performance boosts from AMD until we can get some more specific details on WHAT has changed.  Essentially the company line is that they have finally "caught up" to the GCN GPU architecture introduced with the Radeon HD 7970 in January of 2012.  We traditionally see this happen with new GPU architectures from both vendors but for it to have taken this long is troublesome and will surely cause some raised eyebrows from gamers and the competition. 

We decided to run through the Radeon HD 7870 GHz Edition with this new 12.11 beta driver to compare it to the 12.9 beta driver we had just completed testing on a few weeks ago.  AMD claims performance advantages for all the GCN cards including the 7700/7800/7900 cards though we only had time to test a single card for our initial article.  The results are on the following pages...

AMD Radeon HD 7870 GHz Edition Revisited

There have been quite a few new graphics card releases this year and with the now crowded GPU market, we have gotten many requests to revisit some of the earlier launches to see how they stack up in the latest GPU landscape.  One such card is AMD’s Radeon HD 7870 GHz Edition, which has seen some dramatic improvements since its initial release in March. 

AMD’s entire lineup of graphics cards based on the Southern Islands architecture were released between the months of January and March of this year, with only a few updates during the summer to combat new releases from NVIDIA.  Though they don’t get as much review time anymore, the Tahiti, Pitcairn and Cape Verde GPUs still have a lot to offer gamers and the Radeon HD 7870 GHz Edition is a perfect example of that.

Thanks to recent price cuts, the Sapphire Radeon HD 7870 GHz Edition and all other Pitcairn GPUs can be found for much less than when they were launched.  With a starting price of $350 in March, some base HD 7870s can be found online for $250 and sometimes less with rebates today making it a great deal for gamers on a budget. 

You can check out all of our graphics card reviews right here to see how the market currently stands but there are really very few bad choices anymore.

New HD7970 GHz Editions and new pricing for all models

AMD today announced that the HD7970 GHz Edition will be available on July 16th for a MSRP of $500.  As well there will be a 7870 GHz Edition as well, retailing for around $300 which is a rather nice price point for a premium model of the 7870.  As far as changes to existing models, the Radeon HD 7970 will be available for $429 and the HD 7950 will be available for $349.  While these prices may disappoint early adopters, perhaps the fact that a CrossFire setup has become more affordable will give some comfort.

These new prices will come in conjunction with AMD's "Three-for-Free promotion" which will allow you to choose three DX11 games to acquire for free along with your purchase of a Tahiti based Radeon GPU.  For those on a lower budget, the 7870 GHz Edition will net you a free copy of DiRT Showdown.
