maybe OTOY rewrite a code used something like openCL instead of CUDA? who knows -but I don't buy this as true fact for mentioned reasons - those two AMD cards have only ~10TFLOPS, while 8x 780Tis have ~40TFLOPS combined..=) so wheather it's a bad joke(that slipped on it's own)..or (very unlikelly) OTOY have put a lot of hours into making this happen =p

Imagine all Octane users selling their nvidia cards and getting amd

I've tried OCtane Bench and results are close to rest of users.

But it clearly shows that GTX 780 performance is about 75%-80% of GTX 980 performance and almost SIMILIAR to GTX 970.

So, maybe I'll wait for GTX 980 with more of VRAM.

Strange....

I've got ASUS GTX 780 STRIX 6GB VRAM and got 76 points.

And down in the table are 28 results for 1xGTX 780 with about 83 points.

Look here:

I'm going to check if drivers update change anything. I've got now 344.xx

It's all about your core and memory clock - at stock you should have about 85, on water - 105. What temps do you have? Is this the only card in your case?

I guess Guys are using cards side by side without understanding..they crop part of performance from their cards =)

safe to say, non reference design coolers are not the perfect match for tight multi GPU builds without any spaces in between =)

I'm aware that it's not the best soution, but I'm forced for now to use 4xGTX 780 in one case side-by-side.

I've got temperatures no higher than 80 Celsius on stress.

So now you know how much you lose in terms of performance...At stock (air, but well ventilated) they go at 900mhz, but they can run at 1320mhz at 1.2V.

Yes, but theoretically GTX 980 are less Wattage, less heat generators, so maybe it's more optimal for me?
