Moving from an RTX 4080 to an RTX 4070 Ti Super is not an upgrade: you give up roughly 10 to 15 percent of performance and gain no new features, so 4080 owners should keep their card. If you are buying one of the two today, the RTX 4070 Ti Super is the better value at 1440p, while a fairly priced RTX 4080 is the better pick for 4K and heavy ray tracing.
What Actually Changes Between These Two
Both cards are Ada Lovelace, both use 16 GB of GDDR6X on a 256-bit bus, and both support the same software features. The RTX 4070 Ti Super, launched in January 2024, is essentially a cut-down version of the same AD103 class of silicon used in the RTX 4080, with fewer CUDA cores and less L2 cache. That makes this one of the most direct comparisons in NVIDIA’s lineup: you are trading a known slice of performance for a lower price, nothing more.
Both cards are now previous generation. The RTX 50 series has replaced them, with the RTX 5070 Ti and RTX 5080 as their closest successors. Most buyers will therefore see these cards on the used market or as remaining new stock.

The Performance Gap by Resolution
1440p
At 1440p the two are close, because the faster RTX 4080 is more often held back by the CPU. Aggregated benchmark data shows the RTX 4080 leading by around 5 to 15 percent depending on the game suite. In most demanding titles, both cards push well beyond 100 FPS at 1440p high settings, so the difference is rarely the gap between playable and unplayable.
4K
At 4K the extra cores and cache matter more. TechRadar’s review measured the RTX 4070 Ti Super about 13 percent behind the RTX 4080, and Tech4Gamers reported an average difference of around 14.5 percent, with the RTX 4080 also posting better 1% lows. In Cyberpunk 2077 at 4K, their figures showed roughly a 12 percent lead. Expect the RTX 4080 to be about 10 to 15 percent faster at 4K in most games, with typical demanding titles landing somewhere around 50 to 90 FPS without upscaling, depending on settings, CPU and game version.
Ray tracing
Heavy ray tracing scales with the same hardware advantage, so the gap stays in a similar 10 to 15 percent range, sometimes slightly wider in path-traced games. Both cards rely on DLSS to make path tracing comfortable at 4K.
Features: Identical Toolkits
Because they share an architecture, there is no feature reason to move either direction:
- DLSS 4 Super Resolution: both support the transformer model, which improves image quality over older DLSS presets.
- Frame generation: both support single-frame DLSS Frame Generation. Neither supports Multi Frame Generation, which is exclusive to the RTX 50 series.
- Reflex, NVENC AV1 encoding, Ray Reconstruction: supported on both.
- VRAM: 16 GB on both, enough for 4K with high textures in current games.
If the goal is Multi Frame Generation or a real performance jump, the move from an RTX 4080 would need to go to an RTX 5080 or RTX 5090, not sideways or down.
When a Switch Can Make Sense
There are only narrow situations where trading an RTX 4080 for an RTX 4070 Ti Super is reasonable:
- You can sell the RTX 4080 for meaningfully more than a 4070 Ti Super costs and are happy to pocket the difference for a small performance loss.
- You play at 1440p, where the two often sit close together because of CPU limits.
- You want to reduce heat output slightly; the 35 W TDP reduction is modest but real.
For everyone else, the transaction cost, risk of a used purchase and lost performance outweigh the benefit.
Value Comparison: The Numbers
Using launch MSRPs, take the RTX 4080 as 100 and the RTX 4070 Ti Super as about 88, reflecting the roughly 12 percent average gap at 4K:
- RTX 4080 at $1,199: about $11.99 per performance point.
- RTX 4070 Ti Super at $799: about $9.08 per point, roughly 24 percent cheaper per unit of performance.
On the used market the gap is narrower. An RTX 4080 usually sells for around $750 to $900 used, and an RTX 4070 Ti Super for around $600 to $700, depending on model and condition. At $825 and $650, cost per point is about $8.25 for the 4080 and $7.39 for the 4070 Ti Super. The 4070 Ti Super still wins on value, while the 4080 buys extra 4K headroom for about $175 more.
Also compare against current cards. An RTX 5070 Ti is a new-generation alternative with warranty and Multi Frame Generation, so price used Ada cards below it to make them worth buying.
Power Supply and Case Fit
PSU sizing with the formula GPU + CPU + about 150 W headroom:
- RTX 4080: 320 W + about 150 W for a typical 8-core gaming CPU + 150 W = roughly 620 W. NVIDIA recommends a 750 W supply for this card, which matches that estimate with comfortable margin.
- RTX 4070 Ti Super: 285 W + 150 W + 150 W = roughly 585 W, so a quality 700 W to 750 W unit is appropriate.
Both use the 16-pin connector. ATX 3.x power supplies with a native cable are the cleanest option; otherwise use the included adapter with separate 8-pin cables and seat the plug fully. Both are listed at 310 mm and 3-slot in reference form, and partner cards are often longer and thicker. Check the clearance in your case, including any front fans or radiators, before buying a used card.
A Better Route for RTX 4080 Owners
If you own an RTX 4080 and feel it is no longer enough, the useful moves are upward, not sideways. The RTX 5080 adds Multi Frame Generation and a moderate raw performance increase, and the RTX 5090 adds a large jump plus 32 GB of VRAM, though at a much higher price and power draw. For many 4080 owners, the more sensible step is to keep the card and lean on DLSS 4’s transformer model, which improves image quality at the Performance and Balanced presets enough that 4K with upscaling looks better than it did when the card launched.
Another low-cost option is tuning. Ada cards respond well to modest undervolting, which can reduce power draw and fan noise while keeping performance close to stock. Checking that your CPU is not the bottleneck at 1440p is also worthwhile, because a faster processor can raise frame rates more than any GPU sidegrade in CPU-limited games.

Frequently Asked Questions
How much faster is the RTX 4080 than the RTX 4070 Ti Super?
Published reviews place the RTX 4080 around 10 to 15 percent ahead at 4K. At 1440p the gap is often smaller, in the 5 to 15 percent range, because CPU limits start to matter. Ray tracing results follow a similar pattern.
Is it worth replacing an RTX 4080 with an RTX 4070 Ti Super?
Usually not. The cards share the same features and VRAM, so you only lose performance. It only makes sense if selling the RTX 4080 leaves you with a meaningful amount of cash after buying the cheaper card.
Do both cards have 16 GB of VRAM?
Yes. Both use 16 GB of GDDR6X on a 256-bit bus. The RTX 4080 has slightly higher bandwidth, 716.8 GB/s versus 672.3 GB/s, and more L2 cache.
Can either card use DLSS 4 Multi Frame Generation?
No. Multi Frame Generation is limited to RTX 50 series cards. Both Ada cards support DLSS 4 Super Resolution with the transformer model and standard single-frame DLSS Frame Generation.
What power supply do I need?
A quality 750 W unit is a safe choice for the RTX 4080, and 700 W to 750 W suits the RTX 4070 Ti Super with a typical gaming CPU. Both need a 16-pin connection, either natively from an ATX 3.x supply or through the included adapter.
