Another year of overclocking?
This PowerPC 970 sounds very impressive...Shame it is coming so late, and it still is unclear if it supports AltiVec (which has kept us shackled to the lead turkey G4 and Motorola), which is crucial.
So, what can Apple do for the next year? More overclocking/hacking of the embedded/telecoms focused irrelevance that is the 'Motorola MPC 7455 Host Processor'? Look at Moto's own official documents: The chip does NOT support DDR in any form, or a 167mhz FSB, or an official speed of 1.25ghz, or modern features like out-of-order processing (where instructions are executed in the fastest way possible, rather than just in the order they were issued)...That 7lb heat sink in the latest Macs gives it away, the latest G4s have been overclocked and hacked to the gills by Apple, as they have no choice but to squeeze tiny improvements out of an expensive, out of date CPU that was never designed with Macs in mind.
So what now? Until the 970 arrives, will Apple have no choice but to hack and overclock some more, maybe using exotic cooling methods to force 1.33 or 1.4ghz, and a 200mhzish FSB? Or will Apple come up with another hack (like their 'DDR' implimentation), and shove 4 of these lead balloons into a Mac (never mind they only support 2-way SMP)? Combine this with Apple's 10.2 and .mac rip-offs, forced X booting, underspeccing of machines, etc. and we will lose yet more market share.
If Moto's rumoured '7470' comes along, built on an 0.13 micron process and modernised a bit (real DDR333, 266mhz FSB, 512k L2, 4mb L3, and speeds of 1.6ghz+) we might get some breathing space. If the rumoured '7500' or '8500' (there is already a 'G5'-class CPU, Motos impressive MPC8540, but it is a System-on-a-chip with no AltiVec and is an 'Integrated Communications Processor') with the enhanced e500 core, DDR400 with fast on-chip memory controller, and RapidIO 500mhz FSB then we will be given a new lease on life until IBM comes around.
Dont get me wrong, the 970 is great news, and it is the first real desktop-focused PowerPC since the original G3. The POWER4 is the most powerful CPU available anywhere, and even a 'lite' version will be great, as will be a closer relationship with IBM. I am going to hang on to my maxxed out G3/400 and maybe stick a 7455 in it when i can and wait for Macs that can truly compete and compell again....
