What actually differs
Both GPUs launched in 2026: the MTIA 400 on MTIA and the MTIA 300 on MTIA.
Dense throughput for the MTIA 400 against the MTIA 300: FP8 6,000 vs 1,200 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 288 GB against 216 GB, fed at 9.2 TB/s versus 6.1 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.
