2. The CPUs that are out now are rated 65nm (i think). I know from physics nm = nanometers. What is this measuring? Also, i hear that next generation CPUs will be 45nm (i think)
3. What are dies?
1. Cache is the first stage of execution on your processor. Your data starts out on the large capacity, but relatively slow hard drive and then moves to the faster (but smaller) DDR2 memory. From the DDR2 memory it goes to the L2 cache which is once again smaller, but also much faster. From there it goes to the L1 cache which is even faster but again smaller.
Just think about it as increased speed and decreased capacity.
2. This value is the distance between the transistors on the processors. Core 2 Quads have over 400 millions transistors. The smaller this gap the less voltage leak (that means less power consumption and less heat). The smaller gap means more transistors can fit in the same place, which gives you a faster processors. Finally, more transistors can manufactured for less, which means the price of processors decreases.
3. The die is the core of the processor where all the transistors lay.
