32bit vs 64bit question

32bit vs 64bit question
Which build is faster ? It's not that the emu is slow, in fact I can run it up to 15X faster than normal when playing games. I'm just asking this coz I tried dolphin emu for Wii and the 64bit builds are significantly faster.

BTW, can someone tell me the reason why dolphin emu is so demanding when it comes to CPU ? Besides the specs of the console it emulates I have no idea why one emu is faster than the other so I wanna learn why.

RE: 32bit vs 64bit question
64-Bit has access to more resources, especially RAM, so that's the one to go with.

Specs: Windows 7 x64/Ubuntu 14.04.1 x64 | Intel Pentium P6200 @ 2.13 & 2.13GHz. | 3.68GB RAM | Intel HD Graphics (Integrated)/Intel Ironlake Mobile

RE: 32bit vs 64bit question
64-bit builds can be faster on systems with AMD GPUs(according to solarmystic, iirc), but compatibility can also differ slightly between the 32bit and 64bit versions, so keep both on hand.

Your 2nd question is off-topic, but I'll answer it anyway: Dolphin is so demanding because it's emulating a 483Mhz PowerPC CPU and a 162MHz ATI GPU when running Gamecube games, or a 733Mhz PowerPC CPU, and a 243mhz ATI GPU when running Wii games, not to mention the Wii/GC's DSP sound chip if you're using LLE sound. If you're wondering why PPSSPP might be faster than it, it's because PPSSPP isn't as demanding: by default PPSSPP is only emulating a 222mhz MIPS CPU with a 111mhz GPU, and PPSSPP doesn't need to emulate the actual Media Engine DSP.

If you also mean why are certain games in the same emulator more demanding than another, the answer can vary wildly: It depends on how many polygons are being pushed, what sort of AI is running on the CPU, how the game handles textures, lighting, and geometry, and multiple other things. Another factor that can contribute is if the game is coded poorly, it can be burning a bunch of extra CPU cycles that aren't necessary, which on an emulator can slow things down to a crawl(see Pangya: Fantasy Golf on PSP, I doubt it's that slow because of the graphics...).

If I'm wrong on any points, feel free to point it out, I'm not a guru.

@Sonickyle
Have you tried comparing it ?

@daxtsu
I know it's off topic that's why I made a thread on the off topic section sorry Tongue

I know about the specs of the console that it emulates so I'm asking about the other reasons. Please read the post I linked. Thanks

RE: 32bit vs 64bit question
PSP's MIPS architecture is 32-bit instructions, so there is little to be gained by using 64-bit.
Wii's PPC architecture, however, is 64-bit and there is lots to be gained by using 64-bit.

What? Don't hijack threads. Use the 32-bit version if you're not on a 64-bit OS.
