AMD prepara l'acceleratore di calcolo MI250X con 110 CU e 128 GB HBM2E

AMD is preparing an update to its compute accelerator lineup with the new MI250X. Based on the CDNA2 architecture, and built on existing 7 nm nodo, the MI250X will be accompanied by a more affordable variant, the MI250. According to leaks put out by ExecutableFix, the MI250X packs a whopping 110 unità di calcolo (7,040 processori di flusso), in esecuzione a 1.70 GHz. The package features 128 GB di memoria HBM2E, and a package TDP of 500 W. As for speculative performance numbers, it is expected to offer double-precision (FP64) throughput of 47.9 TFLOP/s, ditto full-precision (FP32), e 383 TFLOP/s half-precision (FP16 and BFLOAT16). AMD’s MI200 “Aldebaran” family of compute accelerators are expected to square off against Intel’s “Ponte Vecchio” Xe-HPC, and NVIDIA Hopper H100 accelerators in 2022.
