[Atomic MPC] AMD gives the 7970 a boost (to 1GHz) - Page 4

With all honesty, the chance of the 7990 beating the GTX690 is pretty slim

The 7970 draws 195W, the GTX690 with its 2 GPU's draws only 270W

Proof;
7970 - http://www.guru3d.com/article/amd-radeon-hd-7970-review/8
GTX690 - http://www.guru3d.com/article/geforce-gtx-690-review/8

The reason why AMD will struggle to beat the 690 with the 7990 is because of power consumption. Remember, the higher the TDP, the hotter the card will run. Kepler is amazingly power efficient which is what allowed the GTX690 to be such a beast. Whilst the 7970 isn't power hungry either, it still consumes ~22W more than the GTX680. The GTX690 is a miracle card because not only does it essentially perform almost identically to 2 x GTX680, it actually uses around 50-60W LESS power. I don't know what kind of black magic Nvidia were using to allow that to happen, but whatever they did, it was an outstanding result.

So, back to the point. Assuming the 7990 is 2 x 7970's, the TDP will be a minimum of 300W but very likely to be 325W-350W unless AMD trim the GPU's, which would in turn, result in a performance loss. The best part about the GTX690 is that it is essentially two complete GTX680's on the one PCB. If AMD need to cut back the 7970's to get a sub 300W TDP, then that will result in performance loss, which means Nvidia wins this time around.

That is why, to be honest, I don't think AMD will release a 7990. More than likely they'll just wait and release an 8990. Unless they design the 7990, accept its not as fast as the GTX690 but price it far more aggressively (say, $750USD MSRP). Then they will have a winner. But if they want to re-take the performance crown, I highly doubt it. Tahiti XT just isn't efficient enough to compete with Kepler in a dual GPU situation.

so all nvida has to do is clock the gtx 680 up 100mhz and well agian it is faster. so what amd needs to do is push it to 1100-1200 if the all can hit 1250 why not push to limits from factory... or just bring out a 7980 when nvidia brings out the 685

Unless you mean financially, in which case they're probably doing fine considering their acquisition of SeaMicro and severing obligations to GF last quarter

No, I meant, desperate to regain the "World's Fastest GPU" crown. They recently lost both the single & Dual GPU crowns which they've been boasting for a while now.

Ordered that 690, did you? kept the reciept?

Perhaps this is the BF3 graph you're looking for?

Its a smaller GPU because they stripped compute from it. Tahiti is as much a compute GPU as it is a gaming GPU, Kepler is just gaming. The fact AMD kept the difference in die sizes to just 65mm^2 is actually pretty good.

Pitcairn is the most efficient GPU this gen, and that belongs to AMD.

Ebb and flow, easy come easy go. The key is to not take it personally, or revel in it. You seem to despise the fact that they raised clocks? It was logical, if not expected that this would happen.

I tried the 7970. I tried the 7950. And I'm never buying another AMD card again after seeing how absolutely crappy their drivers are compared to NVidia's.
At this point, I don't even care if the GTX 680 is 10% slower than the AMD equivalent. I'd much rather take that than the headaches AMD drivers have given me on multiple occasions.

Just to give one example of why AMD's drivers suck.

Nvidia GTX 680: I got this card, pulled my old card out, installed the 680, rebooted. Card detected immediately, downloaded latest nvidia drivers, did a clean install using the option in the installer, rebooted, everything works perfectly. 9.2K 3DMark11 @ stock clocks, 10k when OC'd.

AMD HD 7950. Got this card, pulled out my old card, installed the 7950. Took 3 reboots just for the card to be recognized. downloaded AMD drivers, install them, reboot, card not detected. Nothing but black screen. Returned the card the very next day.

I don't despise it, they can do as they wish.

1) Release 7970 ahead of the competition, and charge $550 for it.

2) Lose the Single GPU crown, and be forced to price it right.

3) Attempt to regain the performance crown by raising the clocks.

4) Profit?

I'm sure AMD is happy that Nvidia didn't drop the GK110 chip. thumb.gif

If it wasn't for Nvidia, you AMD 7970 owners would still be over paying for your cards. smile.gif

Sounds good to me biggrin.gif. Both cards are good in my book. I'm fascinated by AMD and Nvidia's competition against one another, very reminiscent of Subarus Impreza STi and Mitsubishi's Lancer Evolution biggrin.gif
