It’s hard to say until we have a working emulator. You don’t need CPU instructions translation, so it should not be 20X as the case with NES, however even with the same CPU architecture it takes 1.0 GHz host CPU to emulate 66 MHz machine, so it’s actually 15x multiplier.
PS5 emulation is a long ways off, because you generally need 2X faster processor to emulate any console processor.
PS5 has the same x86-64 CPU architecture as PC, but you still need 2X faster graphics card to emulate those fancy raytracing units.
Not necessarily, you can do it with equivalent hardware power if you have a good translation layer like proton
Would there still be a 2x multiplier? PS3 was weird, but does it translate to future Sony systems too?
