FLOPS by Precision

What actually differs

The MTIA 450 is the newer part: MTIA (2027) against the MTIA 300's MTIA (2026).

The MTIA 450 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 18.4 TB/s, which sets the ceiling on decode speed.

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