| DonFerrari said: The boost mode was designed to work 100% of the time and the cooling solution was made around it. TDP will be constant, the thermal will be the same indenpendent of where you are. The frequency will change depending of the load to not overshoot the TDP. As he said if 10% less drain is needed it would be achieved with a very small % drop on the frequency. Also Cerny admitted that their solution to cooling on PS1-4 wasn't always the best solution because of their way to "guess" the worse case, this time they arbitrated it and designed around it, so no jet engine scenario should be expected (although I don't really care about the noise). |
The Boost mode can't work 100% of the time, otherwise there isn't any point in having it, you might as well have static clocks like the Xbox Series X.
We can look to Renoir to see what will happen on the Smartshift front.

Essentially if the CPU+GPU+Memory controllers are pegged at 100%, the CPU, GPU clocks will be reduced from their maximum levels.
But if if either the CPU or GPU is being underutilized, it will send extra TDP to the component in demand and ramp up clockspeeds to their max.
So the 3.5Ghz CPU clock and 2.23Ghz GPU clock are best-case scenarios, performance can and may be allot lower.

It isn't out of the nothing that it was the most asked feature from devs, and why Jason was saying some devs were saying PS5 is the biggest revolution they saw gen over gen. But yes call it secret sauce if it makes you happy. |
Me and CGI are both happy and impressed with the hardware?
