A summary based on specifications and results.
AMD Ryzen 9 7900 is a Desktop processor with 12 cores and 24 threads. It runs at 3.7 GHz and boosts up to 5.4 GHz. It records a PassMark CPU Mark of 48010 and a single-thread rating of 4120. Its stated TDP is 65 W.
Specification context
The AMD Ryzen 9 7900 is a Desktop released in 2023. Recorded specifications include 12 cores and 24 threads, up to 5.40 GHz turbo, a 65 W reference TDP, a 48,010 CPU Mark. Use these figures to understand its position, then compare the results with your software and the complete platform.
The 48,010 CPU Mark is a broad overall-performance measure, while the 4,120 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 AM5. A matching socket is only the first check; confirm the official motherboard CPU-support list, BIOS revision and board power limits.
The 65 W TDP helps size the cooling class, but it is not the same as peak wall-power consumption.
FAQ
The main recorded details are 12 cores and 24 threads, up to 5.40 GHz turbo, a 65 W reference TDP, a 48,010 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 AM5 motherboards, then confirm the official CPU-support list and required BIOS revision for the exact board before buying.
The recorded reference TDP is 65 W. Real consumption can be lower or higher depending on power limits, motherboard, workload and cooling.
This guidance interprets recorded specifications and results; it does not claim hands-on device testing. Results can vary with motherboard, power, memory and cooling.
