FAQ
The main recorded details are 8 cores and 8 threads, a 11,746 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.
A confirmed socket is not recorded here. Use the device model or manufacturer specifications to identify compatible hardware.
A structured TDP value is not currently available. Check the manufacturer specification and device power limits.
This guidance interprets recorded specifications and results; it does not claim hands-on device testing. Results can vary with motherboard, power, memory and cooling.
