RTX 5070 vs RTX 4070 Super for 1440p Gaming Builds

The RTX 5070 and RTX 4070 Super put up nearly identical 1440p framerates despite coming from two different GPU generations, and the reason has little to do with core counts. The RTX 4070 Super actually carries more CUDA cores and more RT and Tensor cores than the RTX 5070, yet the two cards land within a few percent of each other across most raster benchmarks at 1440p. That's the puzzle this piece works through: not which card wins on paper, but why a newer architecture with fewer cores keeps pace with an older one that has more of them, and what that parity means for anyone actually choosing between the two.

The RTX 5070 and RTX 4070 Super at 1440p

Core counts tell you how much raw shader hardware a GPU has, but they don't tell you how well that hardware is fed, how efficiently it's scheduled, or how the rest of the architecture supports it under load. The RTX 4070 Super's larger count of CUDA, RT, and Tensor cores reflects Ada Lovelace's approach to the 70-class tier: more execution units built on a mature, well-understood process. One card's newer architecture trades some of that raw unit count for architectural changes elsewhere in the chip, and at 1440p, a resolution that doesn't push either card into severe bandwidth or compute starvation, those two approaches end up producing very similar frame counts in most games.

This is the empirical floor the rest of the comparison rests on. In a cross-section of 1440p raster titles, the RTX 5070 and RTX 4070 Super trade small leads back and forth, neither pulling away by a margin a typical builder would notice during actual play. Neither card can claim a decisive raster win at this resolution, so any recommendation has to come from somewhere other than the framerate counter. Builders trying to figure out how that narrow spread plays out in the specific games they plan to run can get more out of comparing titles directly than out of averaged benchmark charts. Build Core pairs real performance data with 3D build visualization, so a builder can test both cards against an actual game library and see where the spread opens up or closes before committing to either one.

Memory bandwidth and architectural plumbing

The real hardware distinction between these two cards is memory bandwidth and the supporting architecture built around the newer card's design to move data faster and schedule work more efficiently.

Both cards use the same memory bus width and carry the same amount of onboard graphics memory, so capacity is identical. What differs is the memory technology riding on that bus. The RTX 4070 Super runs 12 GB of GDDR6X at 504 GB/s. The RTX 5070 runs 12 GB of GDDR7, which uses PAM3 signaling standard across all GDDR7 implementations, at 672 GB/s, a 33% jump in bandwidth over its predecessor. That gain raises throughput for the exact same 12 GB, mattering most in bandwidth-sensitive scenarios.

Blackwell adds a handful of other pieces Ada Lovelace simply doesn't have. The RTX 5070 carries 5th-generation Tensor Cores with native FP4 support, a format that matters directly to AI-driven upscaling and frame generation pipelines. It also includes an AI Management Processor, a dedicated RISC-V core whose job is to offload workload scheduling from the CPU, cutting latency when graphics and AI tasks need to run at the same time. The RTX 5070 moves to a PCIe Gen 5 interface, as shown on NVIDIA's RTX 5070 family specification page, while the RTX 4070 Super remains on PCIe Gen 4, as listed in MSI's specifications for that card.

None of this comes free. Power draw climbs with the new architecture: the RTX 5070 runs at roughly 250W against the RTX 4070 Super's roughly 220W. Under straightforward raster workloads, where the two cards perform at similar framerates, that 30W gap means the RTX 4070 Super actually delivers more performance per watt. For a build going into a case with tight airflow, or a power supply sized conservatively, that's a real trade-off, not an asterisk. A builder drawing up a small-form-factor rig or working from an older, more conservatively sized power supply should weigh that efficiency gap as seriously as the bandwidth gain, because it bears directly on thermals and headroom in a way the frame counter won't show. Whether that bandwidth difference changes anything in a specific build depends on the rest of the parts list and the games being targeted, making it a case-by-case question. Build Core's compatibility checking and performance estimates surface exactly that kind of hardware-specific behavior, so a builder can see how the RTX 5070's GDDR7 advantage plays out against a particular configuration instead of relying on generalized benchmark averages.

Ray tracing performance runs counter to what the generation gap implies

Ray tracing is the one workload in this comparison where the newer card does not simply match or edge ahead of the older one. At 1440p, the RTX 5070 can run measurably behind the RTX 4070 Super in ray-traced titles, a reversal that cuts against the usual assumption that a new generation automatically wins the most demanding workload.

Per-game results back this up consistently enough that the pattern isn't noise. The explanation traces back to the same core-count disparity that looked irrelevant in standard raster workloads. Ray tracing leans heavily on dedicated RT core throughput and Tensor core support for denoising, and the RTX 4070 Super simply has more of both. A larger set of RT and Tensor cores from an older design can out-process a smaller set built on a newer one when the workload is shader- and RT-heavy enough to expose that difference, and 1440p ray tracing is demanding enough to do exactly that in several titles.

This doesn't make ray tracing performance a weakness of the newer architecture broadly, and it says nothing about how the newer card compares to other cards in its own lineup. It specifically describes this matchup: the RTX 4070 Super's extra fixed-function hardware gives it an edge in ray-traced scenes that its raster performance doesn't suggest it should have. If a builder's game library leans on ray tracing rather than standard rasterization, they need to weigh this reversal before assuming the newer card is the safer pick by default.

DLSS 4 Multi Frame Generation and the controversy around it

The RTX 5070's most consequential advantage over the RTX 4070 Super has nothing to do with raster or ray-traced rendering. It's DLSS 4 Multi Frame Generation, a feature exclusive to RTX 50-series hardware, and its value to you depends heavily on base framerate and on how you weigh displayed frames against rendered ones.

Multi Frame Generation can dynamically insert up to five AI-generated frames for every one frame the GPU actually renders, and the RTX 4070 Super does not have access to this capability. The older card supports conventional DLSS 3 Frame Generation, which inserts a single generated frame between rendered ones, but it does not get the multi-frame version no matter what driver updates come. NVIDIA extended this feature set further with DLSS 4.5, which shipped Super Resolution improvements and added Dynamic Multi Frame Generation, as detailed in NVIDIA's GDC 2026 materials. That update brought support across more than 400 games and apps and introduced a 6x MFG multiplier, generating five AI frames for every rendered one, all of it restricted to RTX 50-series cards.

The feature is genuinely powerful and genuinely controversial, and builders should take the reasons for that controversy seriously. Technology journalists have pushed back on NVIDIA's published performance claims specifically because those benchmarks used MFG to generate large FPS gains, raising concerns about image quality, input latency, and real-world usability at the settings those benchmarks used. NVIDIA's claim that the RTX 5070 matches RTX 4090 performance holds only under an extreme MFG scenario paired with a low DLSS quality preset, a combination that introduces visible artifacts. The feature's problems concentrate at low base render rates. A builder who is GPU-limited to begin with sees those artifacts before they see any benefit from the smoothed-out frame count MFG produces. DLSS 5 launch benchmarks for NBA 2K27 illustrate this directly: the RTX 5070's base framerate at 1440p, before AI frame insertion, is relatively low, and the displayed figure after MFG is substantially higher than what the GPU is actually rendering.

An unofficial MFG mod exists for RTX 40-series cards, giving some RTX 4070 Super owners a path to similar frame-insertion behavior without upgrading hardware. Tom's Hardware testing found unusual and reproducible input latency behavior with that mod at 1440p, a pitfall expected from an unsupported, still-developing implementation. It isn't a dependable substitute for the RTX 5070's built-in MFG pipeline.

The honest way to evaluate this feature is to treat displayed frames and rendered frames as two separate numbers. MFG multiplies what's shown on screen, separate from what the GPU computes, so the fair comparison is native-versus-native or matched DLSS mode against matched DLSS mode, with MFG output kept in its own column. Builders on high-refresh 1440p monitors with a stable, reasonably high base framerate in their target games stand to benefit the most from MFG. Builders running demanding ray-traced scenes with a sub-60 base framerate will run into the feature's weaknesses before they see its appeal. Modeling the actual build and the base render rates it will produce in specific target games, rather than taking a marketing benchmark at face value, is the step that separates the advertised figure from the real experience. Build Core's 3D build configurator and performance estimates are built for that kind of isolation, so a builder can see what DLSS 4 Multi Frame Generation adds to a particular setup instead of extrapolating from a cherry-picked benchmark.

Pricing in October 2026: what builders pay, not what MSRP suggests

Hardware specs and software features only matter in the context of what a card actually costs, and in late 2026 the pricing gap between the RTX 5070 and RTX 4070 Super is narrow enough, and volatile enough across retailers, that no single number tells the whole story.

Market pricing tracked between September and October 2026 doesn't point in one consistent direction. One pricing aggregator, updated October 4, 2026, showed the RTX 4070 Super running considerably more expensive than the RTX 5070 when both were bought new, making the RTX 5070 the cheaper option by that particular snapshot. But MSRP alone doesn't settle anything either: the RTX 5070 in some markets still sells well above its original launch price, while the RTX 4070 Super has traded below its own launch MSRP in others. Two builders shopping on the same day in different regions, or even at different retailers in the same region, can face opposite answers to which card costs less.

Used market listings add another variable. Availability on the used market skews toward the RTX 4070 Super as its original owners upgrade to newer hardware, so budget-focused builders get a path to lower entry prices that isn't open in the same volume for the RTX 5070. If you're prioritizing the lowest possible cost, check used listings alongside new retail prices rather than assuming new-market pricing is the only relevant figure.

None of this settles into a stable "winner" the way a spec sheet comparison does, because the prices themselves move week to week and market to market. The practical move for a builder is to pull live prices at the moment of purchase from a tool that aggregates multiple retailers, rather than anchoring to an MSRP or a single data point from weeks earlier. That behavior, checking current prices rather than trusting a published figure, matters more to the final decision than any fixed claim about which card is cheaper in October 2026.

Which card belongs in a 1440p build

Given how close these two cards sit in raster performance, how the ray tracing results actually favor the older card in several titles, and how unsettled pricing is right now, the decision doesn't come down to picking a benchmark winner. It comes down to three variables: how long the builder plans to keep the card, how sensitive they are to current pricing swings, and whether they're building a new system or upgrading an existing one.

A builder starting from scratch at 1440p is choosing between two cards that will deliver similar raster performance and should weigh the RT reversal, the MFG feature set, and whatever pricing is live at the moment of purchase, since none of those three factors points in a single obvious direction on its own.

A current RTX 4070 Super owner has one real reason to upgrade to the RTX 5070: access to Multi Frame Generation. Whether that's worth the cost depends on how many of the builder's games actually support DLSS 4, and how much weight they place on a feature set that's likely to keep expanding in scope as an RTX 50-series exclusive. For a lot of RTX 4070 Super owners, holding the current card and waiting for the next generation is a reasonable, defensible choice.

A builder coming from an RTX 3070 or an older card sits in the clearest upgrade position of any profile here. The RTX 5070 offers a large cumulative performance gain over that older hardware, and it adds GDDR7 bandwidth at a point where many 8 GB cards from that era were already showing memory pressure in current titles. That combination, more raw performance and more headroom where the old card was straining, makes the upgrade case strongest for this group. The RTX 4070 Super is also a legitimate upgrade from an RTX 3070 or older, and a heavily discounted used unit can close much of the remaining feature gap for a builder whose priority is raster frames.

For the value-focused builder watching prices closely, a steeply discounted RTX 4070 Super, whether used or new clearance stock, remains a strong 1440p card on current raster performance, provided the build doesn't depend on MFG-heavy workflows. The right answer changes by profile, but in every one of them, checking actual current prices and actual game-by-game performance beats trusting an averaged benchmark chart or a launch-day MSRP that may no longer reflect what either card costs today.
