Comparing Mac's G3 and G4 chips to Athlons and Pentium 4

[GCJ]

Hi folks:

I want to know which is the real processing power of G3 and G4 chips when compared to Pentium 4 or Athlon CPUs, but I haven't found a website with such benchmarks. I've heard that G3 and G4 chips are more efficient, i.e., they perform more work operations at the same speed (in the same way that Athlons perform more operations per work cycle than Pentium 4).

Any one knows the real equivalnce of these chips?? I've had a lot of MAC lovers who tell me that G3 is FOUR TIMES more efficient than a Pentium 4 --> G3 1000 MHz = Pentium 4 4000 MHz ?!?!?!?! This seems like boasting to me ....

Thanks for your help....

The performance on G4's is usually 1.5 times the performance of a similarily clocked Pentium.

Where did you get this information?? How about a G3 chip?? Do they also perform 1.5 times a Pentium 4 does??

Thanks!😎

There's no real way to tell. x86 and the G3\G4 architectures are totally different.

photoshop benchs sound like the best test of speed to me

Maybe SPEC scores? I don't know how well those scores correlate to real life, but I think they're pretty synthetic, which sounds like what you're looking for.

Photoshop is optimized for use on the mac environment, isn't it? So that'd be like using a benchmark that is bias towards one processor over the other.

not really "optimized". it uses the alti-vec engine but that's no different than an application being "optimized" for SSE2 and that other stuff

Performance depends, as always, on software. Run RC-5 on a PPC G4+ and you'll see it perform as fast if not faster than the 3.2 P4. Run Photoshop filters on the P4 3.2 and it'll be significantly faster (perhaps 2x or 3x faster depending on the filter) than a PPC G4+ at 1.4 GHz.
Different processors are stronger in different types of software and there's always there's different levels of optimization required. At least in terms of multimedia, digitalvideoediting.com and aceshardware.com has had some benchmarks for Adobe After Effects, Photoshop and Premiere processing times and the dual 1.4 G4+ systems are consistently outpaced by as much as 2x by a 3.06 P4.
