Summary of technical tests

1. CPU Performance (Stress Tests and Benchmarks)

The Ryzen 7 4700U is an 8-core, 8-thread processor based on the Zen 2 architecture, with a TDP of around 15W. In prolonged tests, it showed consistent results:

• Prolonged loads : Maintains frequencies between 2.9 and 3.2 GHz on most cores without aggressive throttling.

• Frequency peaks : It reaches up to 4.1 GHz in single-threaded tasks, such as opening applications or processing short scripts.

• Multi-core : It performs extremely well for a mini PC, outperforming many equivalent Intel U-Series processors.

In short render and build tests, the CPU remained stable with no noticeable performance drops, indicating good internal thermal design.

2. Graphics performance (integrated Vega GPU)

The integrated Radeon Vega GPU performs as expected for a low-power chip:

• Desktop tasks : Smooth transitions, excellent responsiveness on Windows 11, and no tearing or artifacts.

• Video acceleration : Perfect in 4K HEVC/VP9; smooth playback even with multiple monitors.

• Lightweight games : Esports titles such as League of Legends, Fortnite, or Valorant run between 60 and 120 FPS with appropriate settings.

• AAA games : Require lower resolution to 720p and low/medium settings for smooth gameplay; recent games do not reach optimal levels of playability.

It's not a device geared towards modern gaming, but it does surprise in casual and retro entertainment.

3. Multitasking and productivity tests

Common productivity scenarios were carried out:
