Really excited about this SoC. A great review [1] by ThePhawx shows how it performs at various TDPs. At 15W it's on par with the 8840U, but from 20W on it blows it out of the water (capable of running Cyberpunk at 720p without upscaling at an average of 77 fps). The tablet form factor with such a nice display could make for a great portable console if it ran SteamOS, although the price is pretty prohibitive.
