[WCCF] AMD Radeon HD 7970 (Tahiti XT) Benchmarks Leaked - Page 12

post #111 of 131
I think its just the driver support for multi card causes quite a few problems to big titles when they are released. Single card stability has always been quite good for AMD/ATI.

i thought the 600 series from kepler were only going to be a die shrink, not a new architecture?

Though when using that same q9550 @ 3.6 on my evga 780i board with the 2 gtx470's I have now, and it was a total bottleneck. It scaled but poorly. Couldn't even run crysis at max with max aa. with my i7 that went away and now i see perfect scaling on any game that really needs it. My frames almost doubled in crysis and can run fine at max with max aa running a solid 60fps caped with v-sync.
Multicards work, Just need to get a high end Intel cpu to take advantage of it. AMD cpus do not scale well and are highly not recommended for dual cards.

Yeah the performance is there when they work, but I had such troubles with dual card setup when it came to compatibility and drivers etc. Half of the games it was amazing and the other half were sometimes less fps than just 1 of the cards. I know this is still around because Skyrim doesn't support crossfire yet, which is a huge shame. I'll always stick with a single card because it will work almost 100% of the time right out of the box. Plus on top of that, crossfire cards are often out performed by the next generation of single cards and I just think you may as well wait and upgrade each generation rather than sit it out with crossfire.

Crossfire has worked in skyrim since 11.11c.

Ah fair enough, didn't know that. Still, it's a pretty long time to have to wait. Glad they got it fixed now though.

Nvidia has that, too. It's an optimization thing. You're hitting a cpu bottleneck even though you have cores/headroom free.

Outside of those trouble areas, I get ~60fps with one card and ~120 with two.

Damn, I forgot about this thread. Any new leaks on the 7950 or 7970? All I got is this rumoured release date. But no specs mad.gif

You'll see more leaks once it gets closer to launch from samples being sent out and benches getting leaked. As for now, launch is still a bit away.. wait a couple more weeks and I'm sure some more will start popping up.

I dunno about "a ways away". Another update.
