Re: Well, that's for the previous El Reg article dreaming about a Google's M1-like cloud...
There's nothing to test. The M1 has no external memory bus or chip-to-chip QPI bus, so cannot work in a multiprocessor server and is unable to access more than 64 GB of RAM. By contrast, a dual-processor C621 motherboard can have 4 TB of RAM and 76 Xeon Scalable cores and can handle hundreds of EC2 instances.
