Quote: Originally posted by NETROMac I just have to say that I don't see the point of having 2 "low end" 1.2 ghz processors in the powerbooks. If they put the 1.8 ghz in it, it would have almost the same power, but with less heat and design probl…

Quote: Originally posted by THT Data to the PPC 970 cannot be any faster than the bandwidth of the processor bus. So, how does an inline L3 cache feed more than 6.4 GB/s to the PPC 970 when it's limited to 3.2 GB/s reads and 3.2 GB/s writes (…

Quote: Originally posted by kupan787 If the bus is only 200Mhz, that would be sad. It has the potential to be double that (450MHz real, 900 double pumped). Everyday these guys post more, I start to believe them less. I believe they mean the m…

Quote: Originally posted by Programmer Instead of doing that I expect the memory controller to be run at half the processor speed. So what if bandwidth is a little lower on slower machines? It makes sense from a marketing and technical viewpoin…

The quoted speeds do make some sort of sense, taking rounding into account. If Apple have a memory controller than can cope with a 450 MHz maximum bus speed (900MHz effective due to DDR transmission), and the PPC970 can run it's bus at an integer…
