There are still workloads in which the Altra doesn’t do as well – anything that puts higher cache pressure on the cores will heavily favours the EPYC as while 1MB per core L2 is nice to have, 32MB of 元 shared amongst 80 cores isn’t very much cache to go around. The Neoverse-N1 cores clocked at 3.3GHz can more than match the per-core performance of Zen2 inside the EPYC CPUs. The Altra’s strengths lie in compute-bound workloads where having 25% more cores is an advantage. The Altra Q80-33 sometimes beats the EPYC 7742, and loses out sometimes – depending the workload. ![]() While personally that didn’t surprise me much, I could imagine that for many readers out there this to come as an unexpected turn of events. The Altra QuickSilver being the very first attempt at this, truly hits it out of the park and matches the high expectations of the silicon.Īmpere’s approach is significantly more aggressive, with more performance, and more power, than what the Graviton2 aimed for – the new 80-core Q80-33 flagship SKU essentially has managed to match the performance of AMD’s flagship Rome chip – the 64-core EPYC 7742. That’s where Ampere Computing steps in, positioning themselves as an open merchant silicon vendor, and the first to use and deploy Arm’s new Neoverse CPU line-up in such a way. The only problem with Graviton2 was that this was an internal Amazon-only solution – so you couldn’t really say it was an option against AMD or Intel. ![]() While the promise of Arm servers for many years has been just that – this year’s introduction of the Graviton2 marked the tipping point where Arm server chips no longer represented a niche use-case, but rather a real – and competitive option. ![]() The server landscape is changing very quickly.
