Upcoming PowerMacs, iMacs and eMacs

thanks for this info, arn.
I am waiting to buy a new iMac for home, and also waiting to buy a Dual-Processor PowerMac for work. I already have a G4 PowerBook (although its only 400 MHz), so although I thought the new PowerBooks were cool they were not what I was hoping for. Sounds like I wont have to wait too long to get what I really need. [Sigh of relief]

I wonder which G4 model this will implement, and at what bus speed?

New powermacs - when? Also I'd love to see a single 1.4 ghz powermac priced around 1200 $. But I guess that'll never happen.

I guess 1.43 ghz means 167 mhz bus.

I also wonder what cpu they're going to use because Motorola can only get the G4 up to 1.25ghz for now with no headroom.

Are you sure about that? Some people have overclocked the 1.25 ghz to 1.33 without problems and to 1.5 with some degree of success. (link )


So it's feasible that the updates will keep the same processor, namely the 7455s. BUT, there've been rumors of the .13-micron 7457s debuting at 1.43 ghz in February.

I could definitely see the powermac upgrade happening. It isn't
right to have the ti17 and ti12 to have FW800 while the pMacs
have FW400...... So that is one thing that needs to be changed
in the update, and if it isn't changed then I will be ver suprised.
A dual 1.43 GHz pMac would be awesome especially with faster
DDR, and maybe apple could dual pump the bus. I don't know if
that is possible with the g4 chip, as it is with Wintel computer
chips. Maybe a raise in L3 cache?

Oh, and if they manage to dual pump the bus, or quad pump it, or
whatever, it will still work at 1.43 GHz right?

I wonder which G4 model this will implement

I gotta second this.

..i'd like an imac w/ a g4 and a 1mc cache ...is this feasible?

..failing that , superdrive mk2 and geforce mx/4 w/ 64 mb sgram ??

..any ideas if this might happen ?

I think only the AlBook 17" (not Ti17 it is not made of Titanium...;)) has FW800. But you have a good point, it would make sense for Apple to make those technologies (along with Bluetooth, Airport Extreme...) available to at least the Powermac range.

From what I understand, the G4 processor(up till now at least) was incapable to make full use of DDR. Now I know that Motorola is supposed to update the G4 processor (by the way are we sure we are not going to get the 7457 in at least the Al17"?) but the memory controller allowing full use of DDR is not expected before the second update to the G4, which is not supposed to happen before H2 this year.

That could improve performance a bit but that would definitely look like a stop-gap measure until the arrival of the IBM PPC970. Also L3 cache doesn't come cheap...

My 2 cents

Probably will be 7457 - its in the right timeframe for it, according to the famous Motorola .pdf which was leaked a while back.
Should have 512K L2 cache also. When the Pentium 4 was upgraded in the same way it made quite a difference to performance. If the 7457 can also fully utilise DDR then the two combined should have a marked effect.
