ShaderToyMark and GeForce GTX 580



ShaderToyMark Score for GTX 580
ShaderToyMark score – 960×540 windowed, single GPU



The guys at The Tech Report have tested the GeForce GTX 580 with ShaderToyMark 0.1.0. The interesting thing is that ShaderToyMark seems to nicely reflect the peak shader arithmetic (GFLOPS):
- GTX 580: 1581 GFLOPS
- GTX 480: 1343 GFLOPS

ratio = 1581 / 1343 = 1.17

GTX 580 - peak shader arithmetic (GFLOPS)


These values are also confirmed by Hardware.fr here: Dossier : Nvidia GeForce GTX 580 and SLI



And there is exactly the same ratio with ShaderToyMark scores:
- GTX 580: 307 points
- GTX 480: 261 points

ratio = 307 / 261 = 1.17



And what about AMD’s scores ?

You may be looking between the peak arithmetic rates in table at the top of the page and the results above and scratching your head, but the outcome will be no surprise to those familiar with these GPU architectures. The vast SIMD arrays on AMD’s chips do indeed have higher peak theoretical rates, but their execution units can’t always be scheduled as efficiently as Nvidia’s. In this case, the GTX 580 easily outperforms the single-GPU competition. Unfortunately, this test isn’t multi-GPU compatible, so we had to leave out those configs.

I have to fix the multi-GPU bug in ShaderToyMark (from my tests, ShaderToyMark works fine in SLI but crashes in CrossFire).
