What actually differs
The MTIA 450 is the newer part: MTIA, launched in 2027, against the MTIA 400's MTIA from 2026. Newer architectures typically add lower-precision formats and better throughput per watt, so check the precision rows your workload actually uses.
Dense throughput for the MTIA 450 against the MTIA 400: FP8 7,000 vs 6,000 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 288 GB against 288 GB, fed at 18.4 TB/s versus 9.2 TB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.
For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
