So ... No idea what hardware is in the gamecube / wii. I can not evaluate ... But ... I have the impression that consumption of the emulator is high! At least the processor. Only this!
hey, good comparison :
n64 hardware : 93mhz mips/risc
running on 533mhz x86
multiplier : 5.7
now lets say both risc and x86 improved about the same in terms of speed/clock over the years.
wii : 730mhz risc
running todays 4ghz machines
multiplier : 5.4
so in comparison, even today only via overclock reachable hardware is slower then your 533mhz pentium II years ago for emulation of a comparable console.
the multiplier keeps about the same : you need 5-6 times better hardware to play most stuff properly.
in any case, wii is the newest console(apart mobile ones) that will be emulated in the next maybe 10 years.
think of emulating an xbox360 for example : 3,2ghz * 5-6 -> results in 16-19ghz
Unlikely we see this in next 10 years. and no, more cores do not help.
conclusion : we can be happy with the performance we got with dolphin. its very fast compared to other emus.
Good comparison Iulius also my friend! Very enlightening ... But ... Unless I am mistaken ... Has a "small error" in your comparison ...
93mhz/533mhz = 5.73 is correct!
730mhz/4000mhz = 5.4 is correct!
But ... In my case I have 2 processors 3.0 GHz! Would not be completely 6000mhz ... But something close to it! So ... Indeed we have:
730mhz/6000mhz = 8.2
It is enough that multiplier factor or not? However with 8x more processing, we have menus framerate of 30 frames per second!
Correct me if I'm wrong but its calculation, although correct, is far from reality.
Estate architectures are sure different, but I think it is inpossible that a processor RISK is 5x more efficient than an x86.
You can say that a RISC processor is on average 5x more efficient than an x86?
Gamecube and wii use "power pc" which is the IBM RISC ...
Believe are very good compared processors' clock-to-clock "and maybe 2 or 3x faster depending on the application, but 5x .. I think doubtful ...
Apple replaced the "powermac" that are RISC by "intel" that are x86! Why?
conclusion : we can be happy with the performance we got with dolphin. its very fast compared to other emus... But ... It will be better in the future!
Ah! I had forgotten! For who is seem this little discussion and not understood... But want understand ...
