Looking for an RTX 4080 Ti vs RTX 5080 comparison? First check the model name. NVIDIA’s desktop RTX 4080 family lists the RTX 4080 and RTX 4080 SUPER, not an RTX 4080 Ti. Do not assume a listing using “4080 Ti” means SUPER: ask for the manufacturer’s exact model number. Source: NVIDIA RTX 4080 family.
Correction, September 15, 2026: An earlier version treated “RTX 4080 Ti” as a documented GPU and included unsupported benchmark and hardware claims. This guide now separates the documented models and removes those results.
Which GPU did you mean?
A missing or incorrect suffix changes what you are comparing. Establish whether the seller means RTX 4080, RTX 4080 SUPER or another card before assessing performance or value. A shop title, a generic photograph and a claimed memory size are not enough to resolve a mismatch.
- Request the complete manufacturer part number and photographs of the model label.
- Match that number to the board maker’s product page.
- For a used card, ask for evidence identifying the installed GPU, its condition and the seller’s return terms.

How to compare performance fairly
This page does not contain a verified benchmark dataset. It cannot establish a universal FPS gain or a fixed percentage advantage. Look for tests that identify both actual cards, the game and patch, resolution, quality preset, CPU, driver and test procedure. Compare average FPS alongside frame-time consistency.
Separate native rendering from upscaling and generated-frame results. NVIDIA’s RTX 5080 comparison chart uses different frame-generation modes for the generations, so it should not be read as a native-rendering comparison. Read NVIDIA’s chart settings.
For creative work, look for the application version, project, codec or AI model used. A gaming result does not establish export time or whether your project fits into memory. Test results should match the work you actually do.
Check the whole upgrade cost
Before comparing offers, write down the exact card, delivered price, condition, warranty and return policy. Include any case or power-supply changes in the total. This article provides no current price, stock or discount claim.
Measure space for the specific cooler and its power cable, and follow the card and PSU manufacturers’ installation instructions. Do not infer that every older card is smaller or that every newer model needs the same chassis. NVIDIA explicitly distinguishes reference specifications from partner designs.

Frequently asked questions
Is “RTX 4080 Ti” another name for RTX 4080 SUPER?
Do not treat the names as interchangeable. NVIDIA documents RTX 4080 SUPER as a specific model. Ask the seller to resolve an inconsistent listing before using it in a comparison.
Should I replace an RTX 4080 or RTX 4080 SUPER?
Start with the limitation you want to solve: a particular game’s frame rate, a creative workflow or a feature requirement. Find a matching test and compare the improvement with your net upgrade cost. Keeping a card that already meets your needs is a valid outcome.
Can I use specifications as an FPS prediction?
No. A specification table identifies hardware; it does not replace a measured workload comparison.
