This (2020) reports "Despite the fact that we send the entire data array to the video card and back, sorting on GPU of 800 MB of data is performed about 25-fold faster than on the processor."

This shows a approximately 20x speedup (2021, graph 1 vs 3): https://www.irjet.net/archives/V8/i7/IRJET-V8I7714.pdf https://www.irjet.net/archives/V8/i7/IRJET-V8I7714.pdf
- janwas 5y agoThanks for the example! Sounds like 1.6 GB/s on an entire Tesla K80 (300W TDP). This is in fact several times slower than our results on Skylake (with half the TDP), but note that K80 is from 2014. The "25-fold speedup", as is often the case for such reports, comes from not optimizing the CPU side.
