10% drop in power consumption with a couple percent frequency decrease with minimal performance drop.

So you get a performance drop for intense games, whether it’s the CPU for games that heavily utilize the GPU or an actual TFLOP drop for games that utilize the CPU because the GPU needs to be throttled down. You can bicker about exact numbers even though Sony provided none, the person I quoted and myself have the correct understanding of what Cerny was saying.

It remains to be seen how often the system can actually run at full power. Logic would dictate not often, otherwise there would be no need for a boost mode and variable frequencies. Remember this is the same guy who said like 8TF would be required for native 4K. It’s not like he’s infallible.

People smarter or at least more knowledgeable than us on this have said that if MS used the same method of varying frequencies, the XSX could get to like 14.6 TF. They aren’t, because it’s not smart. Sony will either have a very good, very expensive cooking solution in the PS5, or the console will not run at the max frequencies often.

The person have zero access to the chips and just made a if mathematical scenario on XSX going 2.23Ghz, that doesn't mean it can.

Cerny was very clear that the console can sustain that frequency permanently. And the drop that can be expected.

You are just picking a speculative post and running with it as if it is true because it have the same understanding as yours. DF on the other hand expect even less difference than 12 vs 10.23 would show.

Pema is the most vocal user on saying Tflops is an useless measure and that even on same architeture you can have lesser Tflop outperform higher because of other aspects of the card. So I guess you aren't understanding his point that Tflop is a direct theoretical maximum that always means the same (so 1 Tflop is always 1 Tflop, instead of a AMD Tflop is 0,6 NVidia Tflop or anything the like) but of course the real world perfomance will vary greatly and that is the gain in efficiency every gen see.

Agreed.

I do understand that term will equal the same as long is compared to another theoretical measurement , without taking any device in context.

But never a flop measurement will be equal to the performance a device gives when compared to another (Ps3,360, ps4, ps4, amd, nvidia, etc)

And he isn't disputing that.

The thing I would disagree of his is on the frequency compatibility. Yes you can emulate without it, but having the same clock (which doesn't mean it is more powerful or not) should make the compatibility easier.

But if the compatible frequency was really necessary then PS5 wouldn't be able to do the boost BC for PS4, and Sony is going basically for pure HW BC (logic on the chip) with PS4 from what I understand.
