6990 vs 290x

[astranger200]

so I now own both.

assuming perfect scaling on the 6990, which one is better

[thekeemo]

290x still

If you own both, why are you asking us lol?

Fire up some games and try them both.

 

But yeah, 290 for sure.

Crossfire ain't that great (in regards to supporting developers and timely updates) so I'd be choosing the most powerful single-GPU over a couple of weaker ones and how frame-pacing can be completely fucked using two AMD cards in some game titles (well after game has launched), (google crossfire frame pacing issues)

Yet other games scale really well and its quite amazing seeing 85-95% scaling.

But IMO, not worth the headaches, Faster single-GPU FTW.

I will, but there is no perfect scaling IRL

Both are leaf blowers

6990 has just barely more compute units, has a severely lower clock speed and is significantly older on architecture,

it's peak compute performance is also rated a lot lower

 

290X will perform a lot better especially in new games with higher than usual texture sizes due to much higher memory bandwidth and ammount

 

Firestrike is as close as it goes for perfect scaling,

I have 95%~97% scaling there with Furies

Watercooling a Reference 290 is all TOO easy though, and doesn't cost much at all when seeking out used (AIO) watercooling equipment.

A Childs play upgrade, for extra performance & way lower noise.

only the reference 290x has the issue. 3rd party cards are fine

yeps its a dcu 2 and runs cool as (only gets to 62-3 c when not oced. after testing this 6990 it got to 73, which isn't all that bafd but is loud as hell. tbh noise doesn't bother me at all.

[birdhuman]

of course 290x is better than 6990

well, a 6990 has more cores..

GCN cores are different from non GCN cores. Just like you cannot simply compare cuda cores to GCN cores. Tflops should be better way to compare.
