The MI355X is AMD’s Instinct accelerator positioned against Nvidia’s Blackwell (product page); AMD’s page lists a CDNA4 architecture on TSMC 3nm and 6nm FinFET lithography. In this corpus it appears once: Wafer served GLM-5.2 on it at less than half the cost of the B200 generation, with the software gap that long kept AMD out of frontier serving said to be closing because AI agents now write the kernels.
