Integrated GPU vs Dedicated GPU in Browser Benchmarks

Browser GPU benchmarks are good at exposing whether the browser is using the expected graphics device. A laptop with a dedicated GPU may still run Chrome or Edge on integrated graphics unless the operating system graphics preference is changed.

Reference rows

Device class	GPU	Browser	Mode	Avg FPS	Score	Notes
Integrated laptop	Intel UHD Graphics 620	Edge	Light	42	4,200	Good for compatibility, not Heavy-mode stress
Desktop dedicated GPU	NVIDIA GeForce RTX 3060	Chrome	Heavy	74	37,074	Dedicated GPU baseline
Desktop dedicated GPU	NVIDIA GeForce RTX 4070	Chrome	Heavy	112	56,112	High-end shader throughput row

Do not compare the Intel Light row directly with the RTX Heavy rows. The useful takeaway is that integrated GPUs should start in Light mode, while dedicated GPUs can be evaluated in Heavy mode if the browser stays responsive.

Signs your browser is using the wrong GPU

• A gaming laptop scores like an office ultrabook.
• Chrome's GPU diagnostics show software rendering or disabled WebGL.
• The laptop is unplugged and Windows selects power saving graphics.
• The browser score changes sharply after forcing high performance graphics in OS settings.

Checklist for Windows laptops

Open Windows graphics settings, add your browser, and set it to high performance. Restart the browser. In Chrome or Edge, open chrome://gpu and verify WebGL is hardware accelerated. Then run Light and Medium before trying Heavy.
