| Hash Name | Width | Bandwidth (GB/s) | Small Data Velocity | Quality | Comment |
| --------------------- | ----- | ---------------- | ------------------- | ------- | --------------- |
| __XXH3__ (SSE2) | 64 | 31.5 GB/s | 133.1 | 10 |
| _RAM sequential read_ | N/A | 28.0 GB/s | N/A | N/A | _for reference_ |
