NVIDIA A100 tested
Jules Urbach, the CEO of OTOY (a company specializing in holographic rendering in the cloud), shared first benchmark results of the NVIDIA A100 accelerator.
The GPU is the first, and so far the only, Ampere-based graphics card (or more precisely a compute accelerator). Although NVIDIA announced the immediate availability of the A100 for DGX100 systems, we have not seen any meaningful benchmarks of the A100 yet.
The A100 features NVIDIA’s first 7nm GPU, the GA100. This GPU is equipped with 6912 CUDA cores and 40GB of HBM2 memory. This is also the first card featuring PCIe 4.0 interface or SXM4 depending on the variant.
OctaneBench is a benchmark designed to test OctaneRender performance. The Render was the first commercially available raytracer that fully utilized the GPU. This software runs exclusively on NVIDIA graphics cards as it relies on CUDA technology, thus won’t be seeing any comparison to AMD Big Navi or Arcturus-based graphics cards.
A record breaking ?
The @NVIDIA A100 has now become the fastest GPU ever recorded on #OctaneBench: 446 OB4*
#Ampere appears to be ~43% faster than #Turing in #OctaneRender – even w/ #RTX off!
(*standard Linux OB4 benchmark, RTX off, recompiled for CUDA11, ref. 980=102 OB)

The A100 scored 446 points. We are not sure which result is being compared to A100, but the fastest Turing-based graphics card in OctaneBench is GRID RTX 8000, which scored 328 points. The Volta-based Tesla V100, TITAN V, and Quadro GV100 are still holding up quite well to Ampere, showing 33 to 11% performance loss compared to A100.
