It would make things more interesting, however isn't the PS5's CPU throttled? Meaning it wont always be 100mgz slower, it could be even more depending on the game.. however this solution does seem like it might solve this problem. I don't think either console will be going that route. Not yet anyway, maybe in the mid gen upgrades.
Yes depending on the workload, the cpu could be even more than 100mhz slower on the playstation 5.
Depends on how much power the gpu workload is useing.
Typically, for all but the most depending games, I suspect the playstation 5 will run at its rated speeds though.
