Variable frequencies or Smart shift exist to squeeze more power out of the GPU. There is no boost mode in the PS5. 2.23 GHz is just max clock. What the CPU and GPU in PS5 are doing are just balancing the load between them. 1 / 6
That's why Smart shift exist. To distribute power where it is needed. Some people are really struggling to realize how a variable clock/power system gets more performance out of a certain hardware than one with fixed clocks/power balancing. 2 / 6
PS5 variable clocks are there to balance the load between the CPU and the GPU in order to eliminate per frame bottlenecks, they're not there because "the system can't handle both at max clocks". Whenever there's a bottleneck in either the CPU/GPU, 3 / 6
power can be channeled from either one of them to the other without compromising performance thus making the system more resilient to bottlenecks. power adjustments via Smart shift can happen a couple of time per frame 4 / 6
With a system like the XSX, you just throw fixed power at both and if there's a bottleneck in either the CPU or the GPU at a given time, the bottleneck simply occurs. With locked clocks, some power will be left out on a table, it won't be used 100% 5 / 6
Now, of course the Series X still has a more powerful CPU/GPU, that's not up for debate. This is just to inform that it´s not all about theoretical numbers, efficiency
is extremly important when designing a console. 6 / 6
