This URL redirects to https://www.nvidia.com/en-us/.

The site’s front door pointing at the page it serves there — a locale or CMS landing path, not a move. The origin is still the address of the site, so history stays under it rather than forking to a path that depends on where the measurement ran. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).

Metrics LAB FIELD

Core Web Vitals: failing 3 of 3 assessed from real Chrome users.

Field figures are the p75 across real Chrome users over a 28-day trailing window (2026-09-11 → 2026-10-08), origin-level.

LCP Subparts LAB Throttled

The subparts attribute LCP to your server, resource discovery, download, or rendering. They come from one throttled load, the same one as the filmstrip, so they add up to that load’s LCP rather than the simulated Lab LCP above.

resource load delay 14.97 s
resource load duration 7.52 s
time to first byte 1.16 s
element render delay 125 ms

LCP LAB Simulated vs LCP FIELD

Lab 16.92 s
Field p75 2.68 s

The lab LCP is 6.31× the field p75 — real users likely have above-average hardware or network connectivity.

47.7% of pixels differ — parts of the page change. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
