AMD A6-6420K
Benchmarks & Specs

Last updated:
The AMD A6-6420K was an interesting APU from AMD at the time, offering a successful combination of processor and graphics unit. It is based on the Richland architecture and was manufactured using the 32-nanometer process. Particularly noteworthy is the integrated graphics unit, an AMD Radeon HD 8470D.

This provided more than sufficient graphics performance for many users to smoothly use basic games and everyday multimedia applications, such as playing videos, at the time. The "K" in the name also indicates an unlocked multiplier. This enabled overclocking attempts for technically savvy users, which made this chip particularly attractive.

This processor represented a solid basis for a system with a good price-performance ratio. It was a practical choice for home PCs or office applications that did not require a dedicated graphics card. We saw it as a smart solution for users looking for a balanced system. The AMD A6-6420K offered good overall performance for its intended areas of use at the time, especially considering the integrated graphics chip.

The maximum memory bandwidth was 30 GB/s, which was sufficient for the requirements of the integrated graphics.
  • Integrated AMD Radeon HD 8470D Graphics
  • Overclockable (K-Model)
  • Solid basis for everyday applications
