A summary based on specifications and results.
AMD Athlon Dual Core 5400B is a Desktop processor with 2 cores and 2 threads. Its base clock is 2.8 GHz. It records a PassMark CPU Mark of 914 and a single-thread rating of 985. Its stated TDP is 65 W.
Specification context
The AMD Athlon Dual Core 5400B is a Desktop released in 2009. Recorded specifications include 2 cores and 2 threads, a 65 W reference TDP, a 914 CPU Mark. Use these figures to understand its position, then compare the results with your software and the complete platform.
The 914 CPU Mark is a broad overall-performance measure, while the 985 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 AM2. 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 2 cores and 2 threads, a 65 W reference TDP, a 914 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 AM2 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.
