Microsoft gets its foot in the door

After AMD announced its 4th gen EPYC processors, Microsoft has unveiled its two HX-series and HBv4-series -- next-gen Azure VMs.

The HX-series includes the latest technologies but also AMD EPYC processors but compontents from "Genoa X" which should appear with the H1 GA release next year.

The new VMs feature:

800 GB/s of DDR5 memory bandwidth (STREAM TRIAD).
400 Gb/s NVIDIA Quantum-2 CX7 InfiniBand, the first on the public cloud.
80 Gb/s Azure Accelerated Networking.
PCIe Gen4 NVMe SSDs delivering 12 GB/s (read) and 7 GB/s (write) of storage bandwidth.

Microsoft's testing indicates that the HBv4 and HX perform at least 2x better than the HBv3 series, and around 4-5x better than "four-year-old" server technology. Workloads that have been denoted as being optimized for the new series' include computational fluid dynamics (CFD), finite element analysis, frontend and backend electronic design automation (EDA), rendering, molecular dynamics, computational geoscience, weather simulation, AI inference, and financial risk analysis.
