RTX 5090 resolution pixel count comparison
Compare how many pixels different resolutions draw, and so how much heavier 1440p or 4K is than 1080p.
How it works
A graphics card has to draw every pixel of every frame, so its workload rises roughly with the number of pixels. 1440p has about 1.8 times the pixels of 1080p, and 4K has exactly 4 times the pixels of 1080p.
Pick two resolutions to compare. Upscaling such as DLSS or FSR lowers the pixels the RTX 5090 actually renders.
