In an attempt to improve competitive positions on the market of high-end graphics boards, Advanced Micro Devices not only plans to release a new dual-chip flagship solution, but also to speed up the existing Radeon HD 7970 graphics card, according to unofficial sources. The company is reportedly preparing Radeon HD 7970 GHz Edition with increased clock-speed.

With the launch of AMD Radeon HD 7870 and 7770 graphics card, AMD also introduced "GHz Edition" moniker that should show clock-speed of graphics processing unit on particular graphics card. Back in the days ATI used a similar method to highlight premium parts with "Platinum Edition" and  "XTX" monikers. The rumour has it that AMD is preparing Radeon HD 7970 GHz Edition.

In a bid to make the model HD 7970 more competitive against Nvidia Corp.'s GeForce GTX 680 and imminent GeForce GTX 670, AMD plans to increase clock-speed of the chip to 1000MHz from 925MHz, according to Atomic MPC web-site. Thanks to improved yields of chips produced using 28nm high-performance process technology, most code-named Tahiti XT chips can hit 1250MHz clock-speeds and therefore 1GHz frequency should be safe on commercial graphics cards.

It is hard to expect Radeon HD 7970 GHz Edition to provide tangible performance increase compared to the original version, but it does make sense for AMD to refresh its lineup a little six month after the original introduction of Tahiti. Moreover, assuming that GHz edition graphics cards will feature improved coolers, the model HD 7970 will indeed become more competitive than it is today.

Previously, AMD lowered pricing of Radeon HD 7970 and 7950 graphics cards to $479 and $399, respectively, and started to bundle  provide three DirectX 11 game titles: Dirt Showdown, Nexuiz and Deus Ex: Human Revolution with The Missing Link downloadable add-on.

AMD did not comment on the news-story.

Looking forward to faster clocked 7970s. Hopefully the new stepping/models will allow HD7970 to hit 1300+mhz on air!

Anton, as a side note, I am pretty sure your compute DP performance for HD7800 and HD7700 series is incorrect.

Like Cape Verde, Pitcairn's performance in double precision is limited for compatibility and software development purposes, with FP64 performance limited to 1/16th FP32 performance, unlike HD7900 and HD6900 series where it is 1/4th of FP32 performance.

Double Precision Compute performance:

HD6970 = 676 GFLOPS
HD6950 = 563 GFLOPS
HD7870 = 160 GFLOPS
HD7850 = 110 GFLOPS
HD7770 = 80 GFLOPS
HD7750 = 51 GLOPS

While HD7800 series has good OpenCL compute performance, only the HD7900 series is superior in double precision compute performance over the previous generation HD6900 series.

There are several sources which confirm this:
http://www.anandtech.com/...ding-out-southern-islands
and
http://en.wikipedia.org/w...thern_Islands_(GPU_family)

The lack of fully functional FP64 compute performance in HD7800 series is part of the reason why the GPU die is so much smaller than that of the HD7900 series (212mm^2 vs. 364mm^2).

Also, AMD has dropped the prices of HD7970 to $479 and of HD7950 to $399, which is not reflected in your chart.

isn't this opinion a bit too drastic? people tend to look only on flagships, which is currently dominated by gtx680. however, availability is thin to say the least, and enthusiast market is not exactly main market share.

real proffit battle will be fought on mainstream and entry-level front - only a small number of people are willing to invest into 400-500$ GPU

unlike amd, nvidia currently has only paper-launched cards on entry/mainstream market, and it's unsure when they will actually get out or how well they will perform - and even then, it is the price/performance that will influence customers final decision

in the past we saw lots of GPU of both manufacturers who were inferior to direct competitors, but become "best buy" and sold in substantial quantities after the price has been adjusted

i don't think southern islands is a failure, cards are present at the market and are being sold. actually, it's a nvidia failure to compete on any market other than enthusiast, which is mostly for "showing-off", while being unable to launch more affordable solutions... furthermore, what was nvidia last move? 1000$ card? surely, millions will flock to buy it, and pair it in SLI in their 4000$ rigs.

until whole kepler lineup is available, benchmarked and amd prices (admittingly bit to high atm) lowered, i would refrain of declaring any "nvidia decisive victory" (or amd, for that matter)

I agree with you that top end market is small but you would be surprised how perception changes things (take a look at apple products for example)

ps its magic dust lol

hmmm, but apple sells tens or even hundreds of millions of their products, same cannot be said on high-performance GPUs

and on the budget market, too many factors are involved - clearing of last generation stocks, rebranding old products etc. it's highly dynamic, unlike high-end

I don't recall AIB's telling AMD to release a faster clocked 7970. I specifically recall AMD stating that they purposely underclocked 7970, fully expecting gamers and AIBs to make up the difference. So if the unicorn factory pre-overclocked 1200mhz editions were not found, it's because of AIBs, as many gamers were able to overclock their 7970s to 1200mhz.

Hopefully this new stepping will finally allow AIBs to step up their game. Maybe we'll even see the mystical Sapphire Atomic with 1335mhz GPU clocks.

I think AMD is doing fine because NV isn't able to capitalize on their advantages. They have nothing to counter HD7850/7870 right now. However, it'll be interesting to see how plentiful GTX670 will be and what happens to the GK110 in the consumer market.

Also, keep in mind a lot of sales now happen in the mobile/laptop space where AMD has ~60% market share!

I fail to see how AMD have lost this battle, the 79xx series has been on sale (and available for how many months now) and is now selling in AU for ~$600 for the 1000MHz + version were as the NV 680 is selling @ over $700 and are as scarce as hens teeth

respect to NV for releasing such a great card but in reality its not much better than the HD7970 which was released much earlier and is now selling @ a competitive price (at last)
