Many have been raving about the 750FX for a while, but what about the 750FXe? 750FXe, or an enhanced version of the 750FX, would be entirely the same as IBM's latest G3 processor. However, the 750FXe would sport vector processing like the G4 and IBMs latest, rumored PowerPC processor. But what on Earth would such a thing be used for? It's simple actually. We'd just have to use the following setup (some of the math is calculated): PowerMac - G5 processor from IBM - 64-bit processing - 6.4GBps through system bus - Double-pumped system bus - 400MHz FSB - 200MHz CPU multiplier iMac - G4 processor from IBM - 32-bit processing - 3.2GBps through system bus - 400MHz FSB - 200MHz CPU multiplier Some of my math is probably off, but that's a technical look at my guess for IBM PowerPC processors and Apple's possible use of them. If the rumors are true about these chips ability to scale, both chips could scale to 2GHz. Note: - the FSB of the potential G5 is estimated based on memory throughput information provided in Oct. Microprocessor Forum press release. - the FSB of the 750FXe is calculated with data provided from IBM.com. The 750FX is capable of a 200MHz system bus, with full support for DDR memory (200 x 2 = 400).
