How come I never hear about the 7990?

[xanderlane]

The 7990 is by far the best GPU out there by fact, not even an opinion, so why don't I hear about it much? People are raving about the R9 290x and even AMD is calling it the "the most powerful GPU we've made" even though it's clearly not. I was told one time to get 2x R9s for a super computer even though a 7990 would've been cheaper and MUCH better for the money considering crossfire really doesn't give much of a performance boost in most cases.

 

[Heironious]

Because AMD did not make the 7990.

Edit: Oh, and http://www.tomshardware.com/news/geforce-titan-z-nvidia-gk110-cuda,26391.html would like to have a word with you.

 

[Someone Somewhere]

The 7990 IS crossfire - it's 7970 CF on one PCB. Runs F***ing hot and loud, and isn't really made much.

Plus microstutter still causes a bit of havok.

 

[Rationale]

The same reason you never hear about the 690. The 7990 and 690 are both dual cards. They're monsters as far as raw performance is concerned, but they don't actually work that well compared to a 680, 780, or 7970.

Dual cards such as the 7990 have many of the disadvantages of SLI or Crossfire, such as poor efficiency, high power draw, high heat, limited compatibility in some games, and potential microstutter.

The R9 290X is the fastest single card AMD has ever made; the 7990 is Crossfire in a fancy package.

If we're comparing dual cards, the Titan Z would have it beat and the ROG Mars 760 X2 wouldn't be far behind.

And by the way, SLI and Crossfire do provide large performance boosts, from 85-90% increases in most cases.

most people that complain about power and heat issues don't realize it but they do it due to money concerns i run at 70 air-cooled on 7990 and it outperforms every video card including a Titan black that I've ever tasted in any benchmark or video gamepeople people that cry about this card and its issues can't afford one to begin with in most cases

 

[OverclockAtlanta]

I have only three of those cards so far the only cards that outperform it are the Titan Z and the r 295

another thing that always I thought was funny about the GPU dualdebate was that you never heard about anybody complaining about have too many CPU cores but for some reason they complain about having too many GPU's loo

CPU cores and GPUs are not comparable.

CPUs are made on a single architecture with several cores. GPUs with '2 cores' are actually just 2 GPUs stuck together. They don't interface perfectly, and they're unstable.

lo

You got off subject I never said.they were the same I gave a comparison 2 is better than one
(2x2=4) dual gpu wins until they design a single that preforms better as I wright this no single gpu
Can beat a 760 Mars or 690 or 7990 or r9295 or titan Z....fact
