Benchmarks & Specs

Last updated:
The AMD A4-3420 was once an interesting solution from the APU era. It belonged to the Llano processor family, based on the K10 architecture. Manufactured in a 32 nm process, it offered integrated graphics. The AMD Radeon HD 6410D enabled multimedia tasks and simple games at the time.

We remember how practical this all-in-one solution was for compact systems. Its memory bandwidth was 26 GB/s, sufficient for the requirements of the time. With 0 MB Level 2 and 1 MB Level 3 cache, this processor was tailored for basic tasks. It provided a solid foundation for everyday computing. For its time, it represented a cost-effective option.

It was particularly a good choice for smaller offices or as a media PC. The integration of CPU and GPU on one chip significantly simplified system construction. A separate graphics card was not necessary, saving space and money. This made it an accessible choice for many users. Today, of course, it is no longer a powerhouse.

But for retro systems, it can still do its job.
  • Integrated AMD Radeon HD 6410D graphics
