but i had seen there had been some cpu speed improvements as It can overclock without the thermals...Also the stock speed of the newer ones is 1.8-ghz while the older ones are 1.5-ghz
Stock speed remains the same on the Pi4. The changes inside the SoC give a slight improvement in power gating, but not a huge amount. So overclocked might be very slightly cooler, but not by very much, depends totally on the workload. Not worth the effort in trying to find a C0.
If that's true, why does Bullseye run the C0 chips 300Mhz faster than the B0 chips by default?
Obviously the stock speeds are no longer the same with the new operating system.
If the president of the United States can claim to not know his adminstration was preparing to pay 450K to families who illegally entered the country, surely it's possible an engineer might not know his company was preparing to increase the stock speeds of the C0 by 300 MHz.
At any rate unexpectedly increasing the performance by 20 percent is much better than decreasing it, as happened with many x86 systems to mitigate the Meltdown security bug a few years ago.
