Something interesting a lot of reviews don't consider is that Threadripper, since it's a multi-chip module with each chip having its own memory controller, has a non-unified memory architecture (NUMA), where half the memory will have higher latency because it has to go to the other chip. Some software is written with this in mind, some isn't. Consequently, Threadripper has two modes: NUMA mode (OS sees two NUMA zones and different latencies) and UMA mode (single NUMA zone, single average latency). It may be worth trying both when benchmarking to see what difference it makes. I think most reviewers aside from AnandTech have overlooked this since NUMA hasn't been a concern on the desktop before.
- AlexB138 9y ago> has a non-unified memory architecture (NUMA) Small, pedantic, point of fact, NUMA stands for Non-Uniform Memory Access. You could say Non-Uniform Memory Architecture in this context, obviously, as well.
- TazeTSchnitzel 9y ago…oh, huh, okay. Point taken.
- cat199 9y agoDefinitely agree there is 0 attention paid directly to memory bandwidth tests. Also, most of these are floating point tests as well. As someone who does a lot of systems work on a workstation, these figures are just as important if not more important.
