A fake CAPTCHA asks the viewer to select code sequences that run faster on Granite Ridge than Golden Cove, displaying dense AVX-512-style assembly loops. The joke is that a human must understand obscure processor instructions and microarchitecture performance differences to prove they are not a robot. It works as a reaction to overly difficult CAPTCHAs, especially for programmers and hardware enthusiasts.
