Benchmarks & Specs

Last updated:
Those still working with older systems today may encounter the AMD A8-3820. This processor, based on the Llano architecture, was once a remarkably versatile package. A major plus was its integrated graphics unit, the AMD Radeon HD 6550D. At the time, it often made additional graphics cards unnecessary.

This saved costs and greatly simplified system setup. For everyday tasks like surfing, emails, and video playback, this performance was perfectly adequate. Even today, this processor can still perform its service in older systems. It is still well suited for simple office work or as a basis for a media center.

We were surprised at how well the all-in-one solution worked and how wide a range it covered. It was manufactured using the 32 nm process. This CPU offered a good balance for general computer use at the time. It was a cost-effective option for many users who valued versatility.
