Question 1

What are the desktop Core Web Vitals for web.dev?

Accepted Answer

web.dev desktop-only p75 metrics from Google CrUX: LCP 2434ms (good), INP 64ms (good), CLS 0.100 (good). Desktop typically shows better LCP + INP than mobile due to faster hardware + network.

Question 2

Why is desktop performance better than mobile for web.dev?

Accepted Answer

Desktop hardware (more CPU, more RAM, wired network) typically renders pages faster than mobile (battery-constrained CPU, slower cellular). Most sites show 30-60% faster LCP + 40-70% lower INP on desktop. CLS varies less by device. Compare directly at /web.dev/mobile for the same time window.
