Just to put in perspective the improvement in GPU perf from Xbox Series X vs Xbox One X.
Since RDNA2 is expected to deliver higher perf/clock if we assume that RDNA2 delivers 1.15x perf/clock vs RDNA
12 RDNA2 TFlops = 13.8 RDNA TFlops
According to the latest pcgameshardware review a 13.4 TF Radeon VII (avg clock of 1750 Mhz) is 3% faster than a 9.2 TF Radeon RX 5700XT (avg clock of 1800 Mhz)

Thats roughly 3% better perf for 45% raw flops for Radeon VII. 1.45/1.03 = 1.41. It would be reasonable to say 1 RDNA flop = 1.4 Vega GCN flop
Multiplying this 1.4x we get
12 RDNA2 TFLOPS = 13.8 * 1.4 = 19.32 GCN TFLOPS
Thats 3.22x the perf of Xbox One X GPU in the same power. This has been delivered in 3 years (Xbox One X - Nov 2017, Xbox Series X - Nov 2020). BTW Xbox One X is a mid gen console refresh. If we take the OG Xbox One at 1.3 TF the improvement is roughly 15x. This next gen console is going to challenge PC gaming like no other previous console gen as it has desktop class CPU with 8 Zen 2 cores at 3.66 Ghz. With a mid gen console refresh in 2023 or 2024 the mainstream PC GPU in the $350-$400 price range will continue to be challenged till atleast 2025. PC gaming will never be the same again.
