Im sorry i assumed people you had the intelligence to realise that perfect HARDWARE emulation would actually require HARDWARE.
We do have hardware acceleration that help but having software,speed and compatibility is entireley a different
Now maybe perfect software emulation of the consoles operating parameters and games at an accurate level with speed, well thats an entirely different matter.
But still saying that a SNES requires a 3ghz cpu for 1:1 emulation is a nice very large overstatement.
Basically that roughly translates to saying for accurate gamcube emulation (486mhz cpu) would require over 400ghz
Yet you could accurately get perfect software emulation on dual cores sub 3ghz.
You can see emulators run like shit on the most extreme of hardware or you can see them run butter smooth on the most minimal of devices
(because like i said it mainly due to the optimization of the emulator which is the bigger performance hit)
Heres a littly example look at any emulator in the beginning stages, hell look at the PSP n64 Emulator as poor as it is, it couldnt even run games with graphics when it first came out, now it can at least run certain games like mario 64 at a playable framerate 30fps even if the audio was buggy.
Look at the dolphin emulator, the amount of coding and optimzation that has had over the years, its miles ahead of what its capable off on the same hardware it was using 4 years ago.
And back then i was capable of playing wii games at 1080p and 60fps on a 2.6 ghz quad core and a gtx 280
Which by your standards shouldnt even be capable of playing native resolution at a lower performance rate
Also if you dont want to argue about the word being used in THAT context DONT use it in that context you git
So unless you are trying to run your emulators from potato 3ghz is OVERKILL
