i found this on intel site and i can tell what some of the tings are for in more is better but its what it does like the cache and buss


CPU Speed Processor Cores Bus Stepping Cache Size
2.83 GHz Q9550 4 1333 MHz 45 nm C1 12 MB

2.66 GHz Q6700 4 1066 MHz 65 nm G0 8 MB

2.66 GHz Q9450 4 1333 MHz 45 nm C1 12 MB

2.50 GHz Q9300 4 1333 MHz 45 nm M1 6 MB

2.40 GHz Q6600 4 1066 MHz 65 nm G0 8 MB


3.16 GHz E8500 2 1333 MHz 45 nm C0 6 MB

3 GHz E6850 2 1333 MHz 65 nm G0 4 MB

3 GHz E8400 2 1333 MHz 45 nm C0 6 MB

The cache is very fast, expensive memory that serves just the CPU, it's like a storage place for data to be calculated. Sort of but not 100%.

I believe the nm in the bus relates to the size of physical size of the bus. The lower the nm the less power the cpu uses. I'm not entirely sure about this either.

Perhaps I should have stayed away.

more cashe = good, smaller nm = good

nm refers I think to the die size of the chip in nano-metres. The general rule seems to be a smaller the die size equals less the power draw and a cooler running chip.

that is correct... the smaller the nm, the better for over clocking, the less power (voltage and wattage) and less heat..
