The switch pro definitely won't use a new gpu architecture, because all switch games use precompiled shaders for the maxwell architecture. <br>Firmware RE done by SciresM seems to point to Nintendo reusing the same SoC as in the newer red-box models (mariko), which would make sense since they still have quite a bit of overclocking headroom with them.<br>Some form of 4k upscaling tech wouldn't be off the table though.
