Grab the program AltiVec Fractal Carbon from versiontracker.com and run it.

 

The first run will be G4 enabled code. You can disable altivec code for comparison. Altivec emulation is ALOT faster than plain non-SIMD emulation.

 

 

This is running on a 3.0 Ghz P4 Prescott, 2 Gigs of ram.

I get about 1108 MegaFlops in altivec code.

 

For comparison, on a 1.1ghz G4 (100fsb)

4485 MegaFlops in altivec and 694 Megaflops in non-SIMD run.

 

 

Doing my math, thats exactly 75% faster on a G4.

 

Yikes a tad depressing I suppose.

My system is the dual core AMD X2 4400 running at 2x 2.2 GHz

 

I just applied the 8F1111a(g) patch which is supposed to have better G4/AltiVec emulation.

 

In G4 mode, I got 3.7 seconds / 3633.5 MFLOPS

G4 Disabled: 24.3 / 586.3

 

I did have a ton of other {censored} running in the background, so I don't know if that would have generated a slightly lower score or not :-)

nice scores, about as good as a 1.1Ghz G4 running at a 100 FSB.

 

Oh yes, to the both of you, assuming you got OpenGL working on those sweet systems. Do you mind testing out my N64 emulator? It currently uses a slower interpreter core that seems to stutter in audio even on my 3.0ghz prescott. I was wondering if your systems can run it at a fast enough pace where it runs perfectly. So if you don't mind testing here is the link.

Try out mario64, some bottom of the barrel N64 that are not resource heavy on the N64 platform.

 

Thanks!
