Ever wonder exactly what your CPU is doing? Or what the first computer bug was? Give it a watch.

Intel has started releasing a series of explainer videos as part of a new series called Architecture All Access, and it's actually a good way to learn more about your PC. In each video, senior Intel leaders will go deep on a particular facet of how computers work, starting with, unsurprisingly, the CPU. With the competition between AMD and Intel so fierce right now, it's a great time to learn about the brain of a modern PC.

This week's two-part course is Modern CPU Architecture hosted by Boyd Phelps, the CVP of client engineering at Intel. Phelps has worked on Intel CPUs dating back to Nehalem in 2008, up through the recent Tiger Lake chips.

Phelps does a great job explaining complex topics like branch prediction and CPU microarchitecture in a digestible way. The series doesn't require a doctorate in computer engineering to understand, which is always a plus.
