> Sneller is even better for max throughput. I see https://sneller.ai/blog/avx512-itoa/, which reports ~0.75ns/number for <=7 bytes (compared to ~1ns/n for Champagne-Lemire, I would assume on 3 year newer hardware), but ~2.6ns/number for >=8 bytes (vs ~1.3ns/n for Champagne-Lemire). Perhaps it has improved in the 3 years since the blog post was written? Their main GitHub repository is no longer public, so I don't see a good way to test it myself. |
