Details of IBM's 90nm PowerPC 970FX
IBM has posted the first official information of the PowerPC 970FX (90nm PowerPC) in this PDF entitled "IBM PowerPC Quick Reference Guide".
According to the document (page 10), the PowerPC 970FX is the 90nm version of the PowerPC 970 (G5). A comparison chart reveals that the 970FX consumes 24.5W at 2.0GHz while the original 970 consumes 51W at 1.8GHz. The 970FX speeds are only listed as 1.4-2.0+ GHz, however, revealing no information as to the top speed of the chip, though the Bus of the new chip reaches 1.1GHz (vs 1.0GHz of the PowerPC 970).
The 90nm PowerPC is widely expected to power the next PowerMac revisions, and are currently being used in the recently updated Xserve G5s. The 970FX was first referenced in this rumor report but few other processor details accompanied that report.

Clock it at 1.6 or 1.8 and throw it in the 17inch PB ASAP. My $$$ is waiting.

For a reality check, how much does the chip in the current G4 PowerBook use?

1.1Ghz bus implies 2.2Ghz CPU clock
lets hope that isn't the upper limit for this revision.

10 W @ 1 Ghz is the current g4's power consumption. Clock that fx puppy down to 1.8 or 1.6 and your at about 16/18 watts. Beef up the battery in the current unit and wallah, you have a laptop with about a 2hr battery life that will make the g4pb look like a joke (performance wise). What do those 3ghz p4 laptops consume anyway?

Don't quote me on this, but I remember reading that the G4 in the current powerbooks consumes 10W.. I'm sure Arn can give the actualy numbers.
Of this I'm sure, the 24.5W while impressive as all get out, is probably at least double the current PB.. So maybe not at that speed, BUT even if you put a 1.2GHz G5 in the PB you'd have a 600MHz bus anf the option to get some serious RAM in the box.. that alone would make the current PB's seem like calculators..

Well it is nice to see IBM try to improve things, but why still such a low amount of L1, L2, and L3 cache?
The Pentium 4 was soundily defeated by the AMD 64 FX-51 (L1:128k,L2:1MB) and then Intel released the Pentium 4 Extreme Edition which is just a P4 with L1: 8k, L2: 512K, and a L3: 2MB and then it soundily defeated the AMD 64.
Now the PowerPC 970 has a measily 32K L1 and a tiny 512K L2. Why doesn't IBM/Apple upgrade this tiny thing? I mean there would be a significant speed and performance boost as a result.
Another interesting difference is the transistor count of the three processors. P4EE is 178m, AMD64 is 106m, and Apple is 58m.
Aside from that, Apple needs to put out a true 64-bit OS.

I was just wondering about the power consumption ... thanks. But, I can honestly say that as a traveling professional two hour battery life will never cut the mustard. It burns 12.5 watts at 1.4 Ghz, plus with chip enhancements of the G4 should in itself blow out the present G4s, and have decent battery life. That's my two cents ... :rolleyes:
