I have been trying for a while to find information about "process types?" My problem is I see 90nm and 65nm cores, and from what I've read, the 65nm cores are newer faster and cooler. However, I cannot find any information as to why that is, or even what the 90nm/65nm means (besides 90/65 nanometer). Could someone please offer me a little more insight to the subject? Thanks in advance for any information or references.
