True, but it's still the biggest contributor to the performance

Not really.
You could have 64CU's @ 300mhz.
Or you could have 32CU's @ 600mhz.

They hypothetically would have the same output.
...But that also ignores things like memory buses, caches, various fixed function pipelines and so on.

As if you weren't aware that GPU get clocked down to fit into the tight power consumption maximals of a console. Don't expect the PS5 to come with less than 56 CU, but higher clock speeds instead. That won't work out unless Navi base clock is above 1800Mhz, which I very much doubt.

To get enough distance between themselves and the One X (40 CU @1172Mhz), 56 CU will already have to come with about 1500Mhz. That's already close to max clock rate for Vega and in 14nm definitely too much power consumption and heat for a console. In 7nm this should be much more feasible but will still draw a lot of power.

@bolded: Those are part of the Compute Units (unless you meant CPU Cache too)
