I dont get why commercial sites spread so much hype about RBpi4 while logical deduction cannot follow 3x performance with 0,1 Ghz increase.It is moving from the energy efficient Cortex-A53 cores to the more performance oriented A72 ones. This means changes like a 3 way super scaler vs a 2 way super scaler and more efficient (performance wise) out if order execution. While it will probably not get a 3x increase in every workload there may be some that could see that due to the very slightly higher clockspeed and better IPC. To be fair though I expect the majority of workloads to see a much more modest increase in performance.
Here are some real numbers and datasheets from the raspberry pi foundation>> https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711/
Cpu gets overall performance score about 50% more than previous generation. Linpack test measures only floating point unit.
Judging by other A72 based chipsets, personally I expect some minor improvements in emulation at the limits of what the 3b can handle (so better speed\compatibility for ps1/n64/psp) and for the emulators that are currently way outside it's ability to run to probably stay that way. That being said I have been pleasantly surprised before by the amount of optimization the RPi community has done before getting sysytems to run better on it then they would on similarly specced hardware before, so maybe I will be wrong.
