MacRumors just posted a rumor about possibility of upcoming G4 variant, MPC 7457 with speed ranging from 867 to 1833 Mhz and also 512k L2 and 4Mb L3 Cache. All I can say is... Enough with G4 already!!! Those specs are impressive indeed. 512k L2 and 4MB L3 Cache will definitely contribute to better performances. But I've had (same goes for many of us, I'm sure) enough of G4 variants. My first experience with G4 was Power Mac Dual G4 500mhz. Several years later when I upgraded, it was still G4 (Quicksilver). I really hope Apple does not drag us loyal Mac users around with yet another version of G4 this year. It is time to move on. It is time for G5 or IBM 970 or whatever mystery chip that is capable of competing with Intel and AMD. If these new G4 chips are used, I hope they are for consumer lines such as iBooks and iMacs, while professional line gets something new.
