I was really thinking more about the upcoming PS5 and Xbox Scarlett, which both should have Zen 2 CPUs and Navi GPUs, along with a generous helping of GDDR6 memory and SSDs.
At launch, those systems will probably be very competitive with off-the-shelf PCs. By 2022, they won't look as good.
One thing these new consoles are doing that seems interesting is that they use a huge pool of unified RAM (rather than two independent pools of main+video memory).
