Which one should you buy?
The RTX 5080 16GB replaced the RTX 4080 Super 16GB, and this page answers whether the newer card is worth it over the older one still sold new. In the Tom's Hardware GPU hierarchy (June 2026), the RTX 4080 Super 16GB averages 119 fps at 1440p and 69 at 4K; the RTX 5080 16GB averages 128 and 77. At 1080p the averages are 159 and 167 fps. That makes the RTX 5080 16GB about 8% faster at 1440p (5% at 1080p, 12% at 4K).
Both have 16GB of video memory. In games the RTX 4080 Super 16GB draws about 320W and the RTX 5080 16GB about 360W; power supply advice is 750W (maker's advice) vs 850W (maker's advice). The RTX 4080 Super 16GB is about 304mm long, 3 slots thick and uses the 12V-2x6 plug; the RTX 5080 16GB is about 330mm long, 3 slots thick with the 12V-2x6 plug.
Both use DLSS for upscaling.
Our take: the generational gain is small (8% at 1440p), so buy the older card only if it is clearly cheaper, and the newer one if prices are close.
Good to know
- RTX 4080 Super and RTX 5080 use the 12V-2x6 power plug; older power supplies work with the adapter in the box.
