Intel has specific hardware for XESS on their GPUs which is why other GPUs running XESS have to use the DP4a path instead of XMX

Partially HDR but also full field SDR brightness. They’re a lot dimmer than competing LCD screens (approx 250 nits at 100% brightness).

This is taking a laptop CPU and stuffing it in a handheld. The laptop CPU already has the npu and removing it would require a new SKU which would cost money for special handling for packaging, new firmware, new drivers, and probably more costs I haven’t considered. You would save on the silicon but unless they have high volume, removing the npu is likely more expensive.
