Benchmarks & Specs

The Valve Steam Deck (AMD Custom APU 0405) is a processor developed by AMD, custom-designed for handheld gaming. It utilizes the efficient Aerith architecture, specifically the proven Zen 2 design. Manufacturing using the 7nm process was crucial for a good balance between performance and energy efficiency.

This enables a smooth gaming experience in a compact device. This APU integrates a powerful graphics unit, the AMD Custom Radeon Graphics (Steam Deck). It is perfectly tailored to its application. The clever combination of main processor and graphics unit on a single chip is remarkable. We see how the 7nm manufacturing process plays to its strengths here.

With 2 MB of L2 cache and 4 MB of L3 cache, the processor is well-equipped. In Cinebench 2024, it achieves 57 points in the single-core test. For multi-core applications, it scores 275 points. The maximum memory bandwidth is 88 GB/s. All of this together provides a well-thought-out solution for mobile gaming.
