Alder Lake CPUs get great performance on RPCS3 emulator thanks to AVX-512

The team behind the Playstation 3 RPCS3 emulator was testing how the new Alder Lake architecture behaves with their emulator, and by disabling the high-efficiency cores, the results are impressive. This is because the AVX-512 instruction set is supported only by high-performance cores and its support is disabled when high-efficiency cores are also active.

1 What do you think about these tests from the RPCS3 team? Do you think that could be another good reason to upgrade to Alder Lake?

These were the statements from the RPCS3 team:

If you are using an Alder Lake CPU (Intel 12th Gen) in RPCS3, make sure to disable the small cores, otherwise you will be leaving a lot of performance on the table. By disabling the “E” Cores you get AVX-512 and a higher Ring multiplier. ADL performance is by far the best among any CPU architecture.
11900k vs. 12900K, both at 5.2GHz, both with AVX-512 and HT disabled. In the starting area of God Of War: Ascension, there is a +10 FPS buff, from ~ 68 to ~ 78. The 11th. Intel’s Gen already outscored Zen 3 in RPCS3 by a bit, and 12th. Gen widens the gap even further.

In this way, to obtain the best performance it is best not only to disable the “E” cores but also the hyperthreading in the “P” cores, something that RPCS3 already recommends doing from previous generations. Thus, you will have the best possible performance in the emulation of PS3 games, which is already in an incredible state. The emulator developers recently announced that there is no known game or application that is not capable of booting in the emulator, and according to its official website, 63.67% of the games are 100% playable, and an additional 30.52% is playable. although with bugs or glitches.
