Strange feelings about these CPUs, Kudos for AMD for bringing 32 cores to workstation market for what is probably rather low price, but implementation?
1) 4 channels of DDR4 for 32 cores? Gonna be bw bound in quite a few FP heavy and rendering tasks, DDR4 3200 might help some, probably near 100GB/s, but still, that is tiny bw for such massive core counts.
2) AMD seems to bet a farm on OS NUMA support, hoping that tasks will first get scheduled on node that has memory controller and will stay there, otherwise memory latency is going to be horrible on a platform not known for tight latencies already. 64MB of L3 might buffer this, but very strange platform configuration for sure.
3) Sadly for AMD problem (2) is compounded by (1), since when mem controllers are loaded with requests, latencies go higher and higher, so things are not going to be fun at all. I guess there will be conflicts with bench tool makers like Aida64 etc, with AMD claiming that they offer pessimistic view of memory latencies
