Benchmarks & Specs

Last updated:
The AMD A6-4455M is a mobile processor that once formed a solid foundation for notebooks. It comes from the Trinity architecture and was manufactured in the 32-nanometer process. As a so-called APU (Accelerated Processing Unit), it combines the computing cores of the main processor and an integrated graphics unit on a single chip.

This was then an advanced approach to combine performance and efficiency. One of its particularly positive features is the integrated graphics unit, the AMD Radeon HD 7500G. At that time, this offered remarkable graphics performance for a mobile system. It enabled smooth playback of HD videos and also playing less demanding titles.

Furthermore, the AMD A6-4455M has 2 MB Level-3 cache, which was advantageous for fast data processing. This processor was designed to deliver a balanced package for everyday tasks and multimedia use. Here one recognizes a representative of a time in which AMD deliberately relied on integrated solutions to enable compact and yet capable devices.

It reliably handled the demands of basic productivity and digital entertainment of its era.
