Not exactly a huge Surprise. Next Xbox is launching Holiday 2020, with a Zen 2/Navi based SoC with HW Ray Tracing, just like PS5. Basically everything about the PS5 HW seems to Apply to Scarlett.
Xbox One X is still based on Jaguar CPUs, which are a limiting factor, and adding Zen 2 is going to be an incredible step up in CPU performance, which has been the limiting factor of the Xbox One X. Coupling that with a Navi based GPU with hardware based Ray Tracing should provide a level of fidelity far above even the Xbox One X. Microsoft’s target for Project Scarlett was announced as 120 FPS (which we assume is at 4K) but also variable refresh rate, and support for up to 8K on the hardware. Microsoft states this console will be four times more powerful than the Xbox One X.
