AMD's MI355X is a 1.4 kW liquid-cooled monster built to battle Nvidia's Blackwell

Nvidia's Blackwell accelerators have been on the market for just over six months, and AMD says it's already achieved performance parity with the launch of its MI350-series GPUs on Thursday.

Based on all-new CDNA 4 and refined chiplet architectures, the GPUs seek to shake Nvidia's grip on the AI infrastructure market, boasting up to 10 petaFLOPS of sparse FP4 (double that if you manage to find a workload that can take advantage of sparsity) on the MI355X, 288 GB of HBM3E, and 8 TBps of memory bandwidth.

For those keeping score, AMD's latest Instincts aim to match Nvidia's most powerful Blackwell GPUs on floating point performance and memory bandwidth – two of the most important metrics when it comes to AI training and inference.

This bears out in AMD's benchmarks, which show a pair of MI355Xs going toe-to-toe with Nvidia's dual-GPU GB200 Superchip in ...
