I found a "mechanical" "water cooled" keyboard on bestbuy LMAO https://www.bestbuy.ca/en-ca/product/one-up-h5-water-cooled-dynamic-decoration-optical-switch-pluggable-mechanical-gaming-keyboard/12388972 "Water-cooled technique make the keyboard more attractive"

The thing is that it seems practically no one has it, despite it being available on such a large website.

I was on canada computer when I saw this processor on sale. I swifty proceeded to do some research on the difference between that and the 6400. From what I saw, the only difference is that the 6402p has an HD510 iGPU and a 100Mhz higher base & boost. Am I missing out on something? They share the same socket and have no features that aren't shared between the two of them. Why was it made and what is the purpose of it? it doesn't even show up on userbenchmark.com as no one has it.
