Azure Provides Excellent HPC Cloud Performance With HBv4 Series Powered By AMD EPYC Genoa-X
Immediately when firing off some HPC benchmarks, the generational leap from Azure's HBv3 to HBv4 top-end VM was very profound.
With the NASA NPB benchmarks, the HBv4 instances with Genoa-X were radically faster than HBv3 thanks to the Zen 4 CPUs with AVX-512, the larger L3 cache via 3D V-Cache, DDR5 memory, and other significant generational enhancements. Even with the top-end VM costing double the prior generation, the HBv4 176 vCPU VM tended to deliver the best value in most of the benchmarks.
I wasn't entirely shocked though given all of my prior Genoa-X bare metal testing and being incredibly impressed by AMD's new server offerings.
