I wouldn't hold my breath for RT on a 4 tf machineFor sure, definitely needs 8 cores with ability to multi thread. Just saying if it’s a 1080p machine it won’t have to be clocked as high as SX.
I just think if the CPU is up to scratch and the SSD is still as fast, I don’t see why it would hold the SX back. The GPU only pushing a quarter of the pixels on a 3rd of the power shouldn’t be a problem, obviously RT might not be as good should but will hopefully still be capable.
