[Anand] A Look At Triple-GPU Performance And Multi-GPU Scaling, Part 1 - Page 11

It's only good for benching, for e-peen and ego-stroking, and making 50 times the same build threads all over the internet multi-verse.
Look at the GPU usage in CallsignVega's videos. Up to 99% usage on ALL 4 cards.
You don't own Quad Nvidia cards and don't know anything about them, yet somehow you think you're more qualified to speak about their scaling than someone who actually uses them...

3GB of VRAM is only necessary for triple 30" monitors. The benchmarks showed that 5760x1080 and below, the 570 only had trouble with AvP; which the 6970 did 1 more fps with that extra 720MB...

When both cards are priced equally and one consistently does better, even if the scaling may be 5% worse and still has higher fps in single/dual, which one is actually better?

The op review was a joke. 3.3Ghz? Who has 3-way and only uses 3.3Ghz? They used stock clocks too...

Blindsay, compare the 570s to the 6970/6990. We all know the 590 is a joke. 570s actually perform better. In games that people actually play, instead of just benchmark like Crysis Warhead, the 570 has no problems.

There actually is a reliable average OC-ability for the cards on air. 1000Mhz is a slightly above average OC for 6970/6990s on air. Most people who use volt modding can do this. DCII 570s have absolutely no problems hitting 1000Mhz. Just by reading reviews on OCN you can gauge what are the typical overclocks for each card.

GPU usage does not equal scaling.

AMD was very smart this time around. They knew that the 6970 wouldn't be equal to the 580 with 1GB of Vram so they doubled it, and because of the larger framebuffer it wins/equals the 580. Makes me wanna go for AMD now. ^^

Seeing as the MSI 6950 TFIII is coming out soon, the only price alternative to beat dual 570s @ 940 seems to possibly be 3x 6950s @ 950-1040 since they scale so well up to 3-way. I'm curious to see what the comparison would be like and if MSI's can unlock to 6970s. Only problem is, you can't run Xfire in windowed mode, so frames will drop to a single 6950 when tabbed/multi-boxing.

Since the only argument against the 570 was that you can't do 8xAA in some games.
6000s do scale well at 2560x1600 and below, but have some serious problems with triple 1080p monitors. You'd think the extra 720MB would come out on top here, but clearly not:
BC2:



As long as your average is well above 60fps, 120 vs 116 doesn't mean anything. At that point, when both cost the same you stand to lose PhysX, CUDA, better OpenCL, better Tessellation, 3D gaming and windowed mode SLI.

English is my third language. And the ''kid'' is 41. How old are you? 17?

Answer me in perfect french next, and then you can lecture me on my syntax.

I know bashing someone's writing is the easy way out on the internet, when we are out of any logical arguments, but you can do better then that. Come on. Don't go in that direction. The way I write doesn't have anything to do with the subject... ''Bambi''.

Too easy. Try posting some new reviews/slides instead. Be original.

Sigh. Again. ''You want to try and explain to us how the 4th card is "barely being used" again without any data to back up your statement''. LOL! WE ARE TALKING ABOUT SCALING NOT GPU USAGE! I'm like the 10th person trying to explain that to you. Get a grip, please!

The 4th card in Quad-SLI is SCALING like crap! S-C-A-L-I-N-G. Scratch your head like your avatar a little bit. It will help.
