Reading guide

Read the performance results

The 1,796 CPU Mark is a broad overall-performance measure, while the 695 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.

Platform and compatibility

It uses socket FTB3B. A matching socket is only the first check; confirm the official motherboard CPU-support list, BIOS revision and board power limits.

Memory and power

The 18 W TDP helps size the cooling class, but it is not the same as peak wall-power consumption.

FAQ

Common processor questions

What are the key AMD GX-420MC SOC specifications?

The main recorded details are 4 cores and 4 threads, a 18 W reference TDP, a 1,796 CPU Mark. The tables on this page show socket, memory, cache and graphics data when available.

Is the AMD GX-420MC SOC good for gaming?

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.
