7990?

More about 7990
  1. What does the article say, it's not English.
    But we already know that it will show up in Computex 2012
  2. Each core does 1 Ghz
    Sells for 850$
    Lets see if it happens
  3. I was predicting this, with that specs I might expect average 4-5 % lead to the HD 7990 over the GTX 690
  4. At that price, and if it does whats listed from the link, the 690 is finished, the 690 simply has too much highend polish to compete in price
  5. Yup, nVidia will be in trouble, I knew AMD was gonna strike with the HD 7990. Since the stocked HD 7970 with the 925 MHz is 8% far behind the GTX 680.
  6. If AMD can also pack the overclocking power that the rest of the 7k series has, then it would be a superb card
  7. Tahiti does get better relative to GK104 as the resolutions get higher, so a 7990 with 1GHz core clocks could beat the 690 at the high resolutions that you would expect to use it with, but how much power would it use at load? It would hopefully be less than the 6990 and also be quieter than the 6990.
  8. That's the point, AMD gets the lead @ higher resolution. Consumers wouldn't care too much about the power consumption, but will care about noise & heat issues.
  9. Yup heat & noise will be big questions. I don't believe that power draw matters to 99.9% of enthusiasts as long as temps and noise are in check and power draw isn't absolutely ridiculous.

    I'm not as confident that a 1 GHz clock will beat a 690. I think it would be competitive but not clearly a win - I'm thinking that to score a complete win, it will need to be clocked around 1.1 GHz, but I could be wrong.

    It would be very interesting if two SKUs were released - a 7990 and a higher clocked 7970 x2.

    I agree with it being competitive but not a clear win. A 7990 clocked at 1100MHz or higher should have no trouble beating the 690 when you take into account the 690 does run slower than two 680's.

    I think any reference cooler is loud. I think the 6990 got a bad rap as far as power and noise. I had two 6990's in BIOS position 2 overclocked to 950MHz gpu and 1375MHz memory and my total system draw while benchmarking with all 4 gpus running at 99% was 850W. I really didn't need the 1250W gold series OCZ psu that I bought based on AMD's recommendation. I think if you are spending that kind of money on the best gpu money can buy then power consumption and noise take a back seat to the desire for gpu overkill. :D

    I'm very sure that a 1GHz 7990 would beat a 690 most of the time. Even up to 1GHz, it's already clocked over 8% higher than the 7970 (680 is less than 8% faster than the 7970 most of the time), so it's almost on par with the two 680s (almost because scaling is not exactly 100%) at 2560x1600. Increase that to 5760x1080 or even better, 5760x1200 and the 7990 should beat the 690 since it is ever so slightly slower than two 680s and the 7970 already beats the 680 most of the time at such resolutions. Besides, pump up the AA and the 690's mere 2GB of VRAM per GPU can't keep up (at 5760x1200, 2GB is a killer in some games and makes the 680s/690s unplayable with AA greater than FXAA), so the 7990 would simply win by default in several situations even if it couldn't win in performance alone.
