We're now just over four months before the launch of the next-generation consoles by Microsoft and Sony, the Xbox Series X and the PlayStation 5. With the final units still far from our hands, we are left to wonder which of the radically different approaches used by Microsoft and Sony will prove to be more successful.

For example, while Microsoft opted to keep its console's clock rates fixed, Sony went with the bold choice of using variable frequencies for both CPU and GPU, a decision that made the PS5's 10.28 TFLOPs figure feel misleading according to our own colleagues from Hardware as it only refers to the 'best-case scenarios' when there is no downclocking involved.
