The past two months I've been using the Gigabyte (Giga Computing) G242-P36 and it's been a refreshing delight for an ARM64 server platform running well with the mature Ampere Altra and Ampere Altra Max processors while boasting support for up to two GPUs and up to two DPUs or other PCIe adapters to make for a nice GPU/AI accelerated computing server.
In the absence of AmpereOne servers being widely available and those next-generation Ampere processors just targeting above 128+ cores, the Ampere Altra family is still an ideal candidate for those pursuing an AArch64 server.
