I realize OpenCL, CUDA and Vulkan aren't exactly operating at the same abstraction levels nor with the same quality of software support.
But I was quite shocked to see my GTX 1080ti on a 4.8GHz-Turbo 4-core i7-7700k annihilate an RTX 2080ti on a 3.8GHz-Turbo 18-core E5-2696 v3, when on CUDA and OpenCL the CPUs were generally bored I/O slaves and the RTX 2080ti delivered the relative performance improvements the increased silicon budget promised.
Just have a look at the GB5 compute benchmarks at http://browser.geekbench.com/user/abufrejoval and ask yourself about the validity of RTX 2080ti and GTX 1080ti obtaining 57094/69590 on Vulkan and a more realistic GPGPU result of 161609/53054 on CUDA.
Sure there is a bit of a difference between the monocore compute power of those two hosts 710/1218, but such a heavy CPU dependence seems to invalidate a Vulkan compute benchmark.

Interesting! These results are certainly unexpected and not something we encountered in our testing. We'll see if we can reproduce these results in our lab.
