Yes, the iBook uses the new IBM 750Cx instead of a Motorola 750- see http://www.chips.ibm.com:80/products/powerpc/chips/750cx_pb.pdf For the roadmap, see http://www.chips.ibm.com:80/products/powerpc/rd_map.pdf IBM plans to ship 700 MHz 750Cxe's by the first half of next year. And you're right- I find it interesting that Apple is using an IBM-only built PPC design in the iBook, and what until recently was a Motorola-only built PPC design in the G4's. -Nathan Shaun wrote: Hi everyone, Slightly off topic, but... >I notice that the backside cache on the G3 is only 256k rather than 512k on >previous iBooks, and 1mb on the Pismos. I noticed on Apple's site that it says that this 256k cache runs at the same speed as the CPU. I know on some other chips (Intel etc.) that the cache runs at half the CPU speed, is this the case with the previous iBook / Pismo / etc??? Someone mentioned that this is the IBM PPC chip rather than the Motarola? Is that right? Shaun in YVR ---------- Duo/2400 List, The friendliest place on the Net!
