Re:HPC Systems Special Offer: Two A64FX Nodes in a 2U for $40k by beached_whale on Wednesday August 26, 2020 @12:19PM (#24283931)
In concurrent/parallel scenarios the memory bandwidth is often the bottleneck. So 1TB/s of memory bandwidth over 96 threads is about 10.5GB/s each. Not great, but the 3990x has what, 100GB/s over 64 threads for about 1.5GB/s each?
