[VideoCardz] Rumour: AMD Radeon RX 480 specifications leaked - Page 35

post #341 of 383
So superior to 390X. That's definitely in the range of the GTX 980, maybe even better.

I wouldn't make that conclusion from what I posted. The dual 390X is on a slightly lower clockspeed CPU for one and it's a bit ambiguous to extrapolate frame rates from GPU utilization numbers.

I still can't wrap my head around what math are you using to calculate "would-be-gpu-bound" fps though.

For example, to get Single Batch GPU take 62 fps, multiply it by 49% since it has 51% utilization, and add it to the 62 fps. It gives 100% utilization of 2 GPUs, and then divide it by 2 to get 100% utilization of 1 GPU.

Well, that does not survive much criticism. 1.49x * .51 <> 1x.

Not to mention it makes faulty assumption of all batches being relatively equal.

Well, yes, I figured to reach these numbers would be more work for little difference. I am sure there's even more accurate math.

Yes, this would involve an expectation for them to be relatively equal since this dual 390X are relatively equal, but of course that's just a guess..

100% Dual GPU 480:
Single Batch: 121.6 fps
Med Batch: 86.3 fps
Heavy Batch: 67.2 fps

Average: 91.7 fps

100% Single GPU 480:
Single Batch: 60.8 fps
Med Batch: 43.1 fps
Heavy Batch: 33.7 fps

Average: 45.8 fps

Now you just need derive 1.83x or something from those numbers.

I wonder if he means that it would run at 1.83x a single GPU if there wasn't any CPU bottlenecking. So something like 83.8 fps instead of 62.5 fps.

I don't understand the intense microscopic nitpicking. 390x = 980 at 1440p, 980 is up like 7% at 1080p, 980 is like 6% below a 390x at 2160p.  They're basically the same card. If it equals one it effectively equals the other. The 980 Ti doesn't travel down the Nvidia lineup granting magical performance gains to other cards; at any segment below 980 Ti / Fury X we're splitting hairs.

Beware, cherry picked benchmarks are incoming.
