RTX 4070 Ti Super vs RTX 4080 Super in 2026: Which Wins

The GeForce RTX 4080 Super is roughly 10 to 19 percent faster than the RTX 4070 Ti Super depending on the game, resolution and workload, while using about 35 W more power. Both cards carry 16 GB of GDDR6X on a 256-bit bus and both are built on the same AD103 graphics chip, so the 4080 Super is the faster, fuller version of the same silicon. Pick the 4070 Ti Super if you play at 1440p or want the best value from this generation, and pick the 4080 Super if you want the strongest 4K frame rates and ray tracing headroom in the 40 series.

Both cards are now previous-generation products that NVIDIA has replaced with the RTX 50 series, so buyers meet them as remaining new stock, open-box units or used cards. That changes the decision: the question is no longer only which is faster, but whether either one still beats the newer cards that cost about the same. This guide compares the two on specifications, real gaming gaps, power, thermals, features and ownership, then tells you who should choose which.

Specifications side by side

These numbers come from NVIDIA’s published specifications as summarised by major review outlets. Partner cards often ship with factory overclocks, so boost clocks and board power on a specific model can differ slightly from the reference figures.

Why the two cards perform so similarly on paper

Memory is identical in capacity and bus width. The 4080 Super uses slightly faster memory chips, which lifts bandwidth from 672 GB/s to 736 GB/s, about a 10 percent gain. The 4070 Ti Super compensates with the same 256-bit bus as the larger card, which is a major reason it earned a reputation as a good-value upgrade: earlier 70-class Ti cards used a narrower 192-bit bus and 12 GB of memory. The real separation is in compute: the 4080 Super has about 21 percent more CUDA cores and about 21 percent more ray tracing cores, though its boost clock is a touch lower, so the delivered gain in games shrinks to around 15 percent.

Gaming performance: how big is the gap

Independent reviews measured the 4080 Super about 10 to 19 percent ahead of the 4070 Ti Super. One review that skipped ray tracing found a lead near 16.6 percent, with averages of roughly 104 frames per second against 89. In compute workloads such as Blender rendering, the 4080 Super led by about 19 percent, which tracks its FP32 advantage.

What the gap means in frame rates

These are worked illustrations of the percentage gap rather than results from a specific game. They show an important pattern: a 15 percent lead matters most near thresholds such as 60 frames per second at 4K, and matters least when a CPU or a monitor limits the result. If your target is a fixed 60 fps at 4K without upscaling in the latest titles, neither card is guaranteed to hit it, but the 4080 Super gets closer more often.

Power, thermals and noise

The 4080 Super draws 320 W against 285 W for the 4070 Ti Super, a gap of 35 W or about 12 percent. Since it delivers around 15 percent more frames, efficiency per watt is almost identical. In practice both run cool and quiet on large triple-fan designs, and both undervolt well; many owners cut 50 W or more with a modest voltage curve change and lose only a few percent of performance.

Worked electricity example

Suppose you game four hours a day for a year. The 35 W gap equals 0.035 kW times 1,460 hours, or about 51 kWh. At an electricity rate of 0.15 per kWh, that difference costs roughly 7.7 per year in local currency, which is negligible next to the price difference between the cards. Power cost should not drive this decision; PSU and case airflow should.

Check your power supply carefully. NVIDIA recommends 700 W for the 4070 Ti Super and 750 W for the 4080 Super, and both depend on a 16-pin connector. Use the cable that fits your PSU and push it fully into the socket until it seats; partial insertion is the most common cause of melted-connector reports across 40-series cards. A native 16-pin cable from a recent ATX 3.x supply is preferable to a four-way adapter where possible.

Feature set: identical where it counts

• DLSS 3 and Frame Generation: both support the Ada Lovelace generation of frame generation, and both gain from the newer DLSS super resolution and ray reconstruction updates delivered via drivers. Neither supports the multi frame generation mode exclusive to RTX 50 cards.
• AV1 encoding: both include dual hardware encoders with AV1 support, useful for streaming and video editing.
• Display outputs: both offer DisplayPort 1.4a and HDMI 2.1a.
• Memory capacity: 16 GB suits all 4K games available today with room for texture packs. Neither card will run out of memory in common 1440p play.

Content creation and AI workloads

For video editing and 3D work, the extra 21 percent of compute in the 4080 Super shortens renders by roughly 15 to 19 percent, so a render that takes 10 minutes on the 4070 Ti Super finishes in about 8.5 to 8.7 minutes on the 4080 Super. Machine learning users should note the shared 16 GB memory ceiling: both can run mid-size local models and image generation workflows, but neither fits larger language models without quantization. If memory capacity is the constraint, neither card changes your outcome.

Which card suits which buyer

Best overall pick: RTX 4070 Ti Super for most players

The 4070 Ti Super delivers the same memory configuration and roughly 85 percent of the larger card’s gaming speed at lower power and a lower market tier. It is the card to choose for 1440p ultrawide and high-refresh play, and it handles 4K with upscaling. Its main trade-off is that heavily ray-traced 4K games without upscaling may fall below 60 fps where the 4080 Super would stay above it.

Best for 4K and ray tracing: RTX 4080 Super

The 4080 Super is the pick if you want maximum 40-series performance with no compromises and plan to keep the card for years. The full AD103 chip delivers consistent 4K results with DLSS and extra ray tracing capability. Its trade-off is that the premium over the 4070 Ti Super rarely scales with the roughly 15 percent gain, so you pay more for each extra frame.

What about the newer RTX 50 series?

This is the question most buyers face in 2026. The RTX 5070 Ti uses 8,960 CUDA cores, 16 GB of faster GDDR7 memory and a 300 W limit, and reviews place it roughly at 4080 Super level in many games while adding multi frame generation. If a new 5070 Ti or similar RTX 50 card is available in your region at a comparable tier to a remaining 4080 Super, the newer card is generally the safer long-term buy because it receives the latest driver features first. A used or discounted 4070 Ti Super and 4080 Super remain sensible when the savings are significant and you do not need multi frame generation.

Buying used or open-box: what to check

1. Inspect the 16-pin connector: look for browning or deformation around the pins on the card side. Reject any card with heat marks.
2. Run a stress loop: run a 20 minute loop in a demanding game or benchmark and watch for artifacts, crashes or hot-spot temperatures more than 20 degrees above the core temperature.
3. Check fan behavior: every fan should spin smoothly at idle ramps and at full speed without rattling.
4. Confirm the warranty status: many partner brands tie coverage to the original purchase, so ask for proof of purchase and check whether the warranty transfers.
5. Verify memory health: run a memory test and confirm there are no errors, since GDDR6X heat can age pads on heavy mining or rendering cards.

Durability and ownership realities

• What wears first: fans and thermal pads. Replace pads after several years if memory temperatures climb on a card that has been used for rendering.
• Sag and mounting: both cards are heavy; a support bracket prevents slot stress and connector strain.
• Driver support: 40-series cards are expected to receive driver updates for years, though the newest features arrive on RTX 50 first.
• Common mistakes: using a 600 W power supply with a 4080 Super, bending the 16-pin cable close to the connector, and ignoring case clearance for 3.5 slot designs.

Which games and settings expose the difference most

The gap between the two cards is not uniform, and knowing where it widens helps you judge your own library. Games built on heavy ray tracing, such as path traced showcase titles, lean on RT cores and memory bandwidth, so the 4080 Super’s 80 RT cores and 736 GB/s of bandwidth produce its largest leads there, often at the upper end of the 10 to 19 percent range. Rasterized esports titles and older engines are frequently limited by the processor, so the two cards post nearly identical results and the extra spend buys nothing visible.

Resolution matters just as much. At 1080p, even a mid-range processor struggles to feed either card, and frame rates converge. At 1440p the 4080 Super pulls ahead in demanding games but both exceed 100 fps in most titles. At 4K the larger card’s extra cores and cache show up most clearly because the workload is almost entirely on the graphics chip. The 4080 Super carries 64 MB of L2 cache against 48 MB, and that cache absorbs more memory requests at high resolutions, which is part of why its lead tends to hold at 4K.

Ultrawide, VR and high-refresh displays

Ultrawide 3440 by 1440 monitors push about 34 percent more pixels than standard 2560 by 1440, and 5120 by 1440 super-ultrawide screens push about 78 percent more. On these displays the 4070 Ti Super behaves like a card running a resolution between 1440p and 4K, and it still delivers smooth results in most games with DLSS. The 4080 Super gives extra margin for super-ultrawide panels at high refresh rates.

Virtual reality adds another demand because headsets render two high-resolution images at 90 Hz or more, and a dropped frame is far more noticeable than on a monitor. Players of demanding flight and racing simulators in VR gain the most from the faster card, because they run with supersampling that scales with GPU power. Casual VR players will be satisfied with either.

A sample 4K build and what each card changes

Consider a 4K build with a Ryzen 7 7800X3D, 32 GB of DDR5 and a fast NVMe drive, plus a 4K 120 Hz display. With the 4070 Ti Super, the best approach is DLSS Quality plus high settings, reaching about 70 to 90 fps in most modern games. With the 4080 Super, the same setup pushes into the 80 to 105 fps range, which sits closer to the display’s refresh rate and makes variable refresh rate smoother. The difference is real, but you would be comfortable on either card; the rest of the system rarely changes the verdict.

For a 1440p build with a 165 Hz monitor, the 4070 Ti Super already runs most games above 120 fps with ultra settings. Spending more on the 4080 Super mainly helps in the toughest ray traced titles. Here the better use of extra budget is often a faster processor or a better monitor.

Noise, size and case compatibility

Partner designs of both cards share cooler platforms, so a 4070 Ti Super from a given brand often uses the same cooler as that brand’s 4080 Super. A lower power limit means the 4070 Ti Super’s identical cooler runs cooler and quieter. Many partner models occupy three slots and range from 300 to 350 mm long, so measure your case before buying. NVIDIA’s own Founders Edition cards use a dual slot design, which suits smaller cases but runs hotter at the same power. If your case has limited airflow, the 4070 Ti Super’s 285 W is the easier load for the cooler.

Vertical mounting also deserves attention. Large cards in vertical mounts need adequate clearance from the glass panel, typically 20 to 30 mm, to avoid starving the fans of air. Check the case specifications for the maximum card length and the vertical mount spacing.

Warranty and returns when buying remaining stock

Because both cards are no longer in production, check the seller’s return policy and warranty terms carefully. A new card from an authorised retailer carries the manufacturer’s standard warranty, typically three years for most partner brands, and sometimes longer for premium lines. Open-box cards often keep the original warranty but may require the first buyer’s invoice. Refurbished units from the manufacturer usually come with a shorter warranty. Whatever the route, keep the invoice, register the card if the brand offers registration and photograph the card on arrival.

Frequently Asked Questions

How much faster is the RTX 4080 Super than the 4070 Ti Super?

Reviews put it between roughly 10 and 19 percent faster, with many gaming averages near 15 percent. The gap is larger in ray tracing and rendering, and smaller in games limited by the processor.

Do both cards have 16 GB of VRAM?

Yes. Both carry 16 GB of GDDR6X on a 256-bit bus. The 4080 Super’s memory runs a little faster, giving 736 GB/s of bandwidth compared with 672 GB/s, but capacity is the same.

Is a 750 W power supply enough for the RTX 4080 Super?

NVIDIA recommends 750 W, and that is enough for a typical system with a mainstream processor. If you pair it with a high-power CPU such as a Core i9, or plan to overclock, a quality 850 W unit adds comfortable headroom and keeps the supply out of its noisy range.

Can the 4070 Ti Super handle 4K gaming?

Yes, especially with DLSS Quality or Balanced. Native 4K at maximum settings in the newest titles may fall below 60 fps, but DLSS upscaling brings most games to a smooth level.

Should I buy a 4080 Super or a newer RTX 5070 Ti?

If both are available at a similar tier, the 5070 Ti is usually the better choice because it brings multi frame generation, faster GDDR7 memory and lower power draw, with performance close to the 4080 Super. Choose the 4080 Super only when a discount makes it clearly cheaper.

Do these cards support AV1 encoding for streaming?

Yes. Both include two hardware encoders with AV1 support, so streaming and video exports benefit equally. The faster compute of the 4080 Super speeds up the rest of an editing pipeline, not the encoder itself.
