If you’re interested in PlayStation 3 emulators, and for some reason you don’t want to buy the console itself, the latest Intel Alder Lake processors are one of the best options for PS3 emulation. The new Intel systems provide a significant increase in performance over the previous generation.
According to the makers of the RPCS3 emulator, Intel Alder Lake processors are some of the best processors you can buy right now for PS3 emulation. A test carried out using God of War: Ascension, which was run on an open-source PlayStation 3 emulator, proves that the Core i9-12900K is about 15% faster than the previous generation Core i9-11900K. Both chips are clocked at 5.2 GHz. To make the comparison as fair as possible, all small cores in the Alder Lake processor have been disabled. The AVX-512 instruction set was also included. Both chips also had HyperThreading turned off and were overclocked to 5.2 GHz.
Alder Lake processors are currently one of the best choices for emulating the PlayStation 3. In the case of the RPCS3 emulator, the new processors provide a performance jump of 14% over the previous generation.
If you are using an Alder Lake (Intel 12th Gen) CPU with RPCS3, make sure you disable the little cores, otherwise you’re leaving a lot of performance on the table.
With disabled E-cores you get AVX-512 and higher ring ratio.
ADL’s performance is by far the best of any CPU arch.

The Intel Core 11900K processor was able to offer 68 FPS in God of War: Ascension, while the 12900K was ahead by hitting 78 FPS. This is a 10fps difference, which in this case is a 14% difference in performance. It is not known how much of a difference the AVX-512 instructions make or what the performance looks like with E cores turned on, as the results of such tests have not been disclosed.
The developers emphasize, however, that enabling AVX-512 and disabling E cores provides Alder Lake chips with increased performance in the PS3 emulation tool. Conversely, turning on small cores when turning off the AVX-512 wastes available performance. It seems that the Playstation 3 emulator uses AVX-512 enough that it significantly affects game performance, despite the loss of additional cores.
