The Slim is the newer model, which comes with an upgraded CPU and GPU, but lacks the SD slot and lacks a headphone jack.

The Classic has a more expensive, higher-end GPU, which is able to process 4K video and 4K photos, and has more memory, but no SD slot.

The difference is that the Slim has the built-in WiFi and is priced at €249, while the Classic is €499.

If you’re looking for a portable gaming system, the Slim is better value than the Classic.
