FLOPS by Precision

What actually differs

Both launched in 2026, the MTIA 300 on MTIA and the MTIA 400 on MTIA.

The MTIA 400 carries 72 GB more memory (288 GB against 216 GB), so larger models fit on one GPU before you shard. Bandwidth is 6.1 TB/s against 9.2 TB/s, which sets the ceiling on decode speed.

Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
