Sometimes, you might find it useful or educational to know the microarchitecture of a given CPU. That is, given the brand name of a CPU like
i7-2600K, you might want to know the underlying microarchitecture of that CPU.
I found that the easiest way is to search for the CPU name at the Identify page of CPU World. The search returns some basic information about the CPU. But, at the bottom your CPU should be listed in the Related Pages section. Clicking on its name here shows a page with detailed information about your CPU. Here, you can find the microarchitecture, processor core and stepping information for your CPU.
