2x AMD EPYC 9175F (Turin, 16-channel DDR5-6400 total)

753.6 GB/s is MEASURED by the source with likwid-bench across both sockets at NPS1, against 819.2 GB/s theoretical for 16 channels of DDR5-6400 -- 91.9% of theoretical. Only 8 of the 12 available channels per socket are populated, so this sits below a fully populated Turin build. Two 16-core EPYC 9175F on an Asrock TURIN2D16T; TDP is summed from AMD's 320W per-CPU spec. The build total assumes the same 8 channels per socket as this entry's id, so a reader planning full 24-DIMM population should scale the memory line up by roughly half. Breakdown: CPUs ~$6,688, board ~$1,100, and 16x32GB DDR5-6400 RDIMM ~$27,450. Memory is about 78% of the total and is the single biggest source of uncertainty here -- re-check it first. No used price: the 9175F was released in October 2024 and has essentially no secondary market.
