GeeCoolThe Core i9 12900TE is a 16-core/24-thread low-power embedded part. It games fine: 8 P-cores with solid single-core boost, and games rarely saturate its power budget, so it feels close to a regular desktop i9. The catch is always the system around it — embedded boards set the power limits, cooling, and GPU pairing.
In practice it appears in industrial boxes and OEM all-in-ones that aren't designed for gaming: conservative power, expansion, and cooling. If you want to game on one, verify the system can actually take a GPU and has the PSU for it — don't order on the CPU name alone.
