not gona happen in july, probably not till MWSF, at which point it would be G5'sOriginally posted by rice_web
The newest G4 could easily scale to 2GHz, because of its new architecture (or rumored architecture, rather).
The new G4 is rumored to support/have the following:
- 166MHz system bus (I can only hope for more)
- DDR Memory (can provide an increase of about 10%)
- Silicon on Insulator (increases speed up to 10%, if memory serves)
- .13Micron Manufacturing (less heat, smaller core)
- 512K L2 Cache and/or 4MB L3 Cache (with a smaller core comes bigger caches)
- An unfortunate 12 pipeline stages
- But maybe a better Altivec
The increase in the pipeline stages could allow the G4 to scale significantly (while also hurting performance), and the SOI would allow overclocking dreams. However, when we will see this rumored processor is difficult to say, because rumors also stated that the current batch of G4s could scale to 1.33GHz.
This presents an interesting dilemna, or a nice solution. If the new G4 is ready, then the Pro line could adopt it, allowing the iMac to take the Apollos. This could give us the following at some time in the future:
PowerMac
- G4s at up to 2GHz
- 512K L2 Cache at full processor speed
- 4MB L3 Cache at 1/4 processor speed (1/2 effective)
- 166MHz system bus with DDR at 333MHz
iMac
- G4s at up to 1.33GHz
- 256K L2 Cache at full processor speed
- 2MB L3 Cache at 1/4 processor speed (1/2 effective)
I don't know about you, but if that new batch of G4s offers what is rumored, I'll be a happy camper for a while. With the architecture of the rumored G4, we could see 2GHz G4s by MWSF, and maybe even 1.5GHz G4s at MWNY. Who knows?
With a 512K L2 cache and 4MB L3 cache, an increase in speed could be tremendous.

Qu'est-ce passe avec toi?
Ou a tu trouver ce nouveau chose?
Il'a pas une personne ici qui pense comme toi.
Dit moi ton raison pour cette idee!
Porquoi tu dit que le G4 son passe?
Moi j'ai penser que ce possible mais je prier toi pour une raison.
Une bonne raison, s'il vous plait!
Alors bonne chance et welcome to macrumors, mon ami.

Well, the L3 cache runs effectively at 1/2 the processor speed, so increasing its size would always improve performance. And yes, the G4 desperately needs a larger L2 cache.
I personally would love to see a 200MHz system bus and 400MHz DDR memory, but I think that 166 or maybe even 133 is more realistic.
As for my sources... that's so sketchy. I've just compiled these rumors from all of the rumor sites (even MacRumors.com), and the specs I provided were a general consensus of these rumors. So, it's entirely a rumor! However, some of these rumors date back to about a year ago, and they now seem to be more realistic.
I'd love to see the iMacs adopt the Apollo and the PowerMacs use the next generation G4. This would further differentiate the two product lines and make the PowerMac a more attractive purchase. One of the only excuses that exists for buying a PowerMac is PCI expansion.

I am yet to work with a Quicksilver. Is the difference great enough for me to justify buying one? (or, should I have bought one instead of the iMac, you're saying?)
That's off topic. The point that I was trying to make was that there just wasn't the difference between the two to justify nearly $1,000 for nearly identical products.
