A post published on January 27, 2026 describes an MXFP8 quantizer written in CuTeDSL for the B200 GPU. The technique writes scale factors directly into Blackwell’s packed layout, avoiding an extra packing step before subsequent GEMMs. The reported result is throughput above 6 TB/s.
The example concerns kernel design and data preparation on Blackwell GPUs; it provides no details about measurement methodology or comparative results. To assess the claim, consult the original post and check the test configuration, metric, and measurement conditions.
