Names like Skylake and Cannon Lake are just codenames for the architecture. AMD does the same thing with Matisse, Rome, Vermeer, Milan, etc. I actually find AMD naming mildly confusing Zen 3 Ryzen 5 5600x (Vermeer).

The actual break down is quite simple and described on their website: https://www.intel.com/content/www/us/en/processors/processor...

tldr; Intel processors are numbered like 13900K (13th gen) the first 1-2 digits are the generation. So 9800 is 9th gen 10850K is 10th gen.
