A lot of people here seemed excited for these chips. It’ll be very interesting to see the gaming performance as this could bring in an entire new segment of portable devices running Linux if powerful enough to deliver solid battery life and CPU performance.
It’s not that uncommon in specialty hardware with CPU instructions extensions for a different architecture made available specifically for translation. Some stuff can be quite efficiently translated on a normal CPU of a different architecture, some stuff needs hardware acceleration. I think Microsoft has done this on some Surface devices.
