[QUOTE="Zoolook, post: 691411, member: 21101"] The G4 is a slightly better CPU, clock for clock, meaning if you had a G3 and a G4 with everything else being equal, the G4 would perform better for most modern applications. The G3 ran on a 100mhz system bus, this dictates how quickly information gets from RAM to the CPU and from the CPU to the GPU etc. The G4 runs on a 133mhz system bus, which is significantly faster. Also the G4 iBook has a better GPU. The iBook G3 you have probably has a 32mb ATI Radeon mobility (not a bad chip actually) but the G4 has the Radeon 9200 mobility, more in line with the 8500 desktop chip with shader capabilities etc. So things like transparencies and other effects will be GPU accelerated, rather than running from the CPU. The 80GB hdd is not standard, so you may be lucky and it might be a 5400rpm drive, as opposed to the standard 4200rpm drive. The former is a lot faster than the latter... ask a MacBook Air owner! Also, the 1.2ghz chip breaks the magic ghz barrier... where many applications and web resources ask for, and assume a minimum of, this spec. [/QUOTE]
