Depending on the workload, that's not as impressive as it sounds at first. Single threaded M1 performance is around 50-60% better than the 18-core Xeon in the iMac (which is impressive). But high-core CPUs are typically slower per core. I have plenty of programs that run faster on my dual core laptop than on the 16 and 24 core Xeon servers at work.
- klelatti 6y agoFair comment - I guess I'd assumed that someone with an 18 core Xeon would be running multithreaded workloads!
- rfoo 6y agoOP explicitly said serial program tho.
- ben-schaaf 6y ago> But high-core CPUs are typically slower per core. While this is true for intel CPUs, this hasn't been the case for AMD Threadripper. The 2990wx has marginally higher single core performance than the 2700x (https://www.cpu-monkey.com/en/compare_cpu-amd_ryzen_threadripper_2990wx-886-vs-amd_ryzen_7_2700x-876 https://www.cpu-monkey.com/en/compare_cpu-amd_ryzen_threadri...), while the 3990x has only slightly lower single core performance than the 3700x (https://www.cpu-monkey.com/en/compare_cpu-amd_ryzen_threadripper_3990x-977-vs-amd_ryzen_9_3950x-932 https://www.cpu-monkey.com/en/compare_cpu-amd_ryzen_threadri...).
- bsagdiyev 6y agoI think that’s the “typically” portion, and the comparison was against Intel anyways which does seem to follow that.
