| Totaldemon said: This guy comment explains it well: Let's start with that "plausible" Broadway rumour. You can't just take 3 single core In-Order-Execution chips and slap 3 together and make it a triple core Out-Of-Order Execution CPU. However, IBM ensures the Power ISA is always backwards compatible such that a newer PowerPC or even Power CPU can run code designed for a much older generation of CPU. Think how all modern x86 CPU's can still run programs from a decade ago. And as the article states, Nintendo's programmers have found an easy way for Wii backwards compatibility in the new chipset: Further, IBM had no plans to reduce the older PowerPC chips (like Broadway) to anything below 90 nm. Ever wonder why Broadway was never given a die shrink? The chips on display are clearly 45nm, a size Broadway, modified or not, never has and never will reach. |
I've said these exact words (almost so exact that it's creepy) a few weeks ago.
