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 (2026-08-15 → 2026-09-11), 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 20.58 s
resource load duration 4.48 s
time to first byte 1.18 s
element render delay 42 ms

LCP LAB Simulated vs LCP FIELD

Lab 18.58 s
Field p75 2.61 s

The lab LCP is 7.11× the field p75 — real users likely have above-average hardware or network connectivity.

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
As rendered

87.6% of pixels differ — the page changes substantially. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.

Axe violations axe-core 4.13.0, full rule set

26 violating nodes across 4 rules, 1706 passing. This is a standalone Axe CLI run and is stricter than the subset Lighthouse already includes.

  • moderate region — All page content should be contained by landmarks 18 nodes
  • serious aria-tab-name — ARIA tab nodes must have an accessible name 6 nodes
  • critical aria-required-children — Certain ARIA roles must contain particular children 1 node
  • moderate landmark-unique — Landmarks should have a unique role or role/label/title (i.e. accessible name) combination 1 node

Accessibility failures 2 of 32 audits

  • aria-required-children — Elements with an ARIA `[role]` that require children to contain a specific `[role]` are missing some or all of those required children. 1 node
  • label-content-name-mismatch — Elements with visible text labels do not have matching accessible names. 1 node

Best Practices failures 1 of 19 audits

  • deprecations — Uses deprecated APIs 2 items

SEO failures 3 of 10 audits

  • link-text — Links do not have descriptive text 4 items
  • crawlable-anchors — Links are not crawlable 1 item
  • robots-txt — robots.txt is not valid 1 item
