An interesting post from Vladimir on V-Ray cuda rendering. A Threadripper 3990X gets a better CUDA benchmark score than a GeForce 2080 ti.
Looks like AMD already has excellent raytracing hardware; it’s not a GPU though, it’s called “Threadripper”. According to the V-Ray 5 benchmark, a single Threadripper 3990X is twice as fast as a GeForce 2080Ti running the same code. Other tests that I’ve done recently also more or less confirm this although results vary somewhat based on the scene. This is in part due to some optimizations in our CUDA CPU fallback to make better use of the CPU.
It’ll be interesting to see whether they will develop this.
