More realistically, though, what about this: Ignoring Altivec, other stuff like that and the rest of the computer, a vast generalization could be made that MHz and Pipeline length are the only two determining factors in processor performance. Since each stage in a pipeline takes one clock cycle to complete, you could say something like this:
G4 = 7 stages ÷ 800MHz = 7 ÷ 800,000,000 Hz = 0.00000000875 s = 8.75 x 10 ^ (-9) seconds per instruction = 8.75 seconds per billion instructions. Or, alternatively, 0.114 GigaFlopsP4 = 20 stages ÷ 2,000,000,000 Hz (2GHz) = 1 x 10 ^ (-8) seconds per instruction = 10 seconds per billion instructions. Or, 0.100 GigaFlops
Obviously, these figures are not accurate in the real world, but I wonder if they correlate to each other accurately, so,
7 ÷ G4 MHz = 20 ÷ P4 MHz
20/7 * G4 MHz = P4 MHz
2.86 * G4 MHz = P4 MHz :eek: :eek: :lol:Wow. Isn't that funny. I got 2.86. I didn't even think that I would get close to 2.8, but I thought It would be interesting to approach it from a different angle.
Well, I guess that's where iJosbo235 got 2.8.

--------------------------------------------------------------------------------They don't. The accuracy of the content your post is so close to zero as to make no detectable or statistically significant difference from zero.
Oh wait, my mistake. You didn't spell anything incorrectly, and your grammar is above rebuke. There's your accuracy in a nutshell.
AYB, did I do the right thing? I think so.

A bit soft and beat-around-the-bushes with the remark about good grammer. i would have made a snyde remark about him not understanding the concept of pipelining and that if wishfull simpletons like him could make such easy and simple deductions about general MPU performance, then there would be a SAMS's book called, "Learn Computer Engineering in 30 Minutes"
I would then ask him if he had even heard of Amdahl's Law.
Then of course, I would question his upbrininging and threaten to do nasty things to his dog. :cheesy:

P4 = 2200, G4 = 1000
P4 = 2.2 * G4

I'm surprised you didn't pull the Official Tagline out of your bag of tricks.
I must know: What is the Official Tagline?
