The H800 has lower NVLink bandwidth compared to the H100, and this, naturally, affects multi-GPU communication performance. DeekSeek-V3 required a total of 2.79 million GPU-hours for pretraining ...
The H100 also includes a new Transformer engine aimed at accelerating Transformer modeling by six times over previous architectures. Its fourth-generation NVLink accelerates PCIe performance by ...
The product’s predecessor, the H100 NVL, only connected two cards via NVLink. It’s also air-cooled in contrast to the H200 SXM coming with options for liquid cooling. The dual-slot PCIe form ...
