- rbanffy 4y agoThey are the top performing ARM computers you can go to a store and buy. I'd love to have an HPE Ampere or a POWER tower under my desk, but it's not easy to get anything like those, and certainly not for a price competitive with generic x86.
- NikolaNovak 4y agoAre we confusing things? They're both RISC, but P9/P10/etc is based on IBM's own Power microarchitecture (possibly open sourced / open standard), I wasn't aware it had anything to do with Arm? I could be hopelessly wrong... Or do you mean something different with "POWER"?
- mhh__ 4y agoOwning an IBM Power system is a daydream of many nerds apparently. And power is open in that the ISA is open. Power10 is a bang up to date CPU so the internals are all closed.
- rbanffy 4y agoThere are other interesting ISAs that are not arm64. Sadly, the only ones that still could be viable desktop (more like deskside) are either server-grade ARM or IBM's POWER (and none of them makes Mac Minis).
- monocasa 4y agoI would be shocked if an A64FX core could go toe to toe with a Firestorm on general code. It just doesn't make sense for Fujitsu's use case to spend nearly as many gates on general improvements versus more vector ALUS.
- mhh__ 4y agoThe A64FX is a very specific microarchitecture that's aimed at big core counts rather than being a single threaded monster.
