Buying tips

Threadripper PRO 3945WX: 12 cores, Zen 2 PRO, socket sWRX8, DDR4 memory. sWRX8 takes Threadripper PRO 3000WX and 5000WX (WRX80 boards). PRO chips from Lenovo workstations are often vendor-locked. Vendor lock: many used EPYC and Threadripper PRO chips were fused to Dell, HPE or Lenovo boards (AMD Platform Secure Boot) and will not boot anywhere else. Listings that say "locked" are hidden by default; listings that say nothing may still be locked — ask the seller. Engineering samples (ES) can have lower clocks, bugs or need special BIOS; they are hidden by default. Qualification samples (QS) are usually identical to retail chips.

How this table works

We collect Buy It Now listings from eBay US several times a day and divide the total price, including shipping, by the number of cores. Only processors we can identify by model are listed, and the core count comes from the model, not from the listing title (titles are often wrong). Lots are counted by their total cores; pairs are shown by default, bulk lots of three or more only when you tick the box. We remove coolers, brackets and tools, CPU and motherboard bundles, damaged chips and offers far below every other listing for the same model.
