Digital Foundry has published its thoughts on what could be hiding behind the Xbox Series X’s “massive casing.” Based on what Microsoft has confirmed thus far regarding performance (12 teraflops of power), the Series X must be sporting a GPU that’s more powerful than any Navi card that’s currently on the market. DF also estimates that the power consumption could surpass 300 W based on the average thermals of the Radeon RX 5700 XT and potential cooling room granted by Series X’s casing.

…based on the processor image released at E3 combined with the sheer size of the case, even at a highly clocked 2.0GHz, we’d still require 48 compute units to get the job done – a 20 per cent increase over the Radeon 5700 XT, today’s most capable Navi GPU. And that 48 CU allocation wouldn’t include redundancy, where we’d expect a further four deactivated CUs to increase yield from the production line.
