How to compare PPC clockspeeds with x86?

[ppc_michael]

I was telling my friend about my 1.67GHz G4 and immediately she scoffed and said "1.67?? My Pentium 4 runs at 3.2GHz." Obviously she doesn't get it.

What speed Pentium can I tell her my 1.67GHz G4 compares to?

PPC-Pent.

i believe it would be equal to a 2.4ghz pent. !! around that

Ask her how much L2 cache she has?

What is the bus speed of the CPU?

What is the memory speed?

Gimme a break, I laugh at people ever since the PII days when apple was so far behind in the Megahertz wars. I had a 733 and it could beat or meet any P3 around 1.5Ghz. L2 cache is nice.

What most folks dont get is a G4 and G5 isnt all that great if you compare them one on one vs say Intel or AMD. Now compare 2 vs one and things get better but a 1.67 G4 is about equal to say 2.2 P4. Jobs aint giving PPC the Boot because they are so Great.

I dunno about that. I would dare say my 867mhz G4 powerbook is very comparable to a 1.5ghz pentium processor or AMD equivelant. So, close to double. The general concensus is that PPC x 1.5 = x86 equivelant. But it really depends on what you are using the computer for.

And on the cache of the processor etc

Celeron = low L2 cache but can have high Mhz.

Cheap processors for low end dell machines might be 3.0Ghz but in reality are no faster than a 2.0Ghz of a better CPU.

personally, i don't think you can straight compare clock speed or give a rough estimate on how much faster they are in clock speed. the fundamental architectures are vastly different, therefore they will accomplish different task better. for example, PPC does video encoding way faster than an x86, but x86 kicks PPC butt in audio encoding. so to ask someone which one is better for video editing? sort of a hard question to answer unless you know what they are specifically doing. a lot of audio or video?
