The 109,939 CPU Mark is a broad overall-performance measure, while the 3,782 single-thread result adds context for less-parallel work. Compare the nearby alternatives on this page and do not treat one score as a verdict for every application.
It uses socket SP5. A matching socket is only the first check; confirm the official motherboard CPU-support list, BIOS revision and board power limits.
Verify the system memory type, real power limits and cooling capacity.
FAQ
The main recorded details are 48 cores and 96 threads, up to 4.10 GHz turbo, a 109,939 CPU Mark. The tables on this page show socket, memory, cache and graphics data when available.
The product name or CPU Mark alone cannot answer that. Check single-thread performance, core count, the target graphics card, gaming resolution and results from the games you play.
Start with SP5 motherboards, then confirm the official CPU-support list and required BIOS revision for the exact board before buying.
A structured TDP value is not currently available. Check the manufacturer specification and device power limits.
