Blender Benchmark

Like the title says Blender Foundation released a benchmark, it has comparisons with CUDA, CPU, OpenCL and which is faster on the link.

Did a quick test, and on the BMW scene my CPU renders as fast as my GPU :D

No surprise the new AMD 32 core CPU's are fastest, but looking at the raw power involved, it's not a massive jump in power per core.

It will be nice to see how one's PC compares :)

An older 8 core i7 3960K + GTX970. Still plenty fast for what I'm doing atm.

Clocked the full benchmark yesterday at two hours, one minute and 13 seconds.
I still feel that rendering in Blender can be sped up a lot, as it is not as fast as the competitors. But it's free ;)

Looking at other benchmarks with more recent Intel 8 cores, I still feel that both AMD and Intel are going snail pace with this.

A modern 8 core Intel CPU is roughly 20-25% faster than my 3960K with the BMW benchmark plugin, but that CPU is 8 years more recent in tech.
The 32 core AMD is 4 times as fast, but has 4 times more cores. With speed increases over the years I would have expected it to be much much faster.

It doesn't make me run to the store for a new PC, a new graphics card... sure..

Thx. Yeah, probably only the new raytracing Nvidia deserve it. A Vray dev says that the raytracing cores will offload the ray calc from CUDA cores. So more CUDA cores, eventually optimized and more of them plus not having to do ray calculations will give a sizable speed increase for RTX cards pending obviously that the render engine is updated to employ the ray tracing cores.
