Assassin's Creed Odyssey should be good example of next-gen game core utilization capabilities:

Hardware configuration of both consoles was announced officially in last month.
They have seven of those eight cores dedicated exclusively for running games.
With all the out of control bloatware PC can't claim same.
And then some people even install additional PC bogging down RGB crapwares...
In GPU new Xbox's basically has 30% more processing units than 5700 XT.
So even with only small processing efficiency improvements that would be very strong GPU.
And architecture is no doubt improved in all areas.
RDNA 2 was likely AMD's long term GPU goal with development priority over Navi etc.
Just like Zen uarch development for getting CPUs back on track limited resources available for graphics department.
PS5's GPU doesn't have as many processing units, but goes for higher clocks.
Really the weakest spot of next-gen consoles will be small memory increase.
PS4 had 16 times the memory of PS3, but now its only doubled to 16GB.
Which is probably the amount of VRAM in next top graphics cards with like 10-12GB becoming new high end graphics card norm inside year or so.
Then add separate RAM of PC...
Instead consoles seem to aim for using special techniques for streaming some data from SSD just before need instead of keeping all assets in memory.
Very tight integration and optimizing of fixed hardware makes such "band aids" easier.
PC doesn't have such easy short cuts.
Also drive space consumption is no doubt going to jump because to be "on the fly" streamable game's assets can't be compressed much.
Similarly super fast start up time of game itself would need game's code to be stored in kind of "hibernation file" form instead of usual binary code.
