i wanted to post a few questions on here about CPUs.
1. what is processor stepping?

This seems a bit older, but the primary difference you will see from the Core 2 era is the addition of the memory controller on the chip (and other stuff, but that was the biggest change going to Core i7 gen1). Basically, talking to various devices on the computer (system) requires special chips or on-chip devices. In the Core 2 line, the CPU had to talk to the memory controller in order to get data to and from the memory. This limited memory performance to the speed at which you could transfer to and from the controller. The first Core i7 CPUs had the memory controller right there on the chip, allowing the CPU to talk directly to the memory, greatly improving memory performance and even allowing for faster RAM clock speeds.inscrieredirectoare wrote:2. what is the big difference between core 2 duo/quad and the new i7 line?

JBI did explain this, but those sizes also influence transistor size. Bigger transistors generate more heat because more electricity flows through them. Clocking the chip at a higher speed also results in more flowing electricity and therefore more heat. So shrinking the process means that you can achieve higher speeds. And, of course, electricity actually has to flow in order for the CPU to work, so shrinking distances also improves speed because electricity doesn't have to travel as far.4. what about 45nm and 65 nm and 22nm? what so great about getting a smaller .... is it die or chip? but what so great about making whatever it is smaller?
