GeForce RTX 4090 vs GeForce RTX 4070 SUPER: Full Comparison
Introduction
Choosing a graphics card often involves balancing performance needs with budget and system requirements. This comparison examines two distinct offerings from NVIDIA’s Ada Lovelace generation: the flagship GeForce RTX 4090 and the more mainstream GeForce RTX 4070 SUPER. We will analyze their specifications, gaming performance, features, and power characteristics to help clarify which card may align better with specific use cases, from extreme gaming to efficient content creation.
Performance and Architecture
Both cards are built on the same Ada Lovelace architecture, featuring third-generation RT Cores and fourth-generation Tensor Cores. However, the scale of their silicon differs substantially.
- RTX 4090: Utilizes the full AD102 GPU with 16,384 CUDA cores. It is designed for maximum throughput, offering performance that can handle 4K gaming with high frame rates and ray tracing enabled, as well as accelerate professional creative workloads.
- RTX 4070 SUPER: Uses the AD104 GPU with 7,168 CUDA cores. Its performance is tailored for smooth 1440p gaming and is capable of venturing into 4K with adjusted settings. It represents a strong performance uplift over its non-SUPER counterpart.
In benchmarks, the performance gap is typically substantial, with the RTX 4090 often delivering 50-70% higher frame rates at 4K resolution. For 1440p gaming, the RTX 4070 SUPER provides a highly capable experience.
Memory and Bandwidth
Video memory (VRAM) capacity and bandwidth are critical for high-resolution textures and future-proofing.
- RTX 4090: Features 24 GB of GDDR6X memory on a 384-bit bus, providing 1,008 GB/s of bandwidth. This large pool is beneficial for 8K gaming, AI research, and working with large 3D models or video files.
- RTX 4070 SUPER: Equipped with 12 GB of GDDR6X memory on a 192-bit bus, resulting in 504 GB/s of bandwidth. This is generally sufficient for 1440p and many 4K gaming titles, though some modern games at maximum settings may approach this limit.
Power and Thermal Design
The power and cooling requirements of these two GPUs highlight their different performance tiers.
- RTX 4090: Has a higher Total Graphics Power (TGP) rating, typically around 450W. It generally requires a robust power supply (often 850W or higher) and a well-ventilated case. Its physical size is also notably larger.
- RTX 4070 SUPER: Is more efficient, with a TGP around 220W. It can often run on a 650W power supply and fits into a wider variety of PC cases due to its more compact board designs.
For users conscious of electricity usage or upgrading an existing system, the RTX 4070 SUPER’s lower power draw can be a significant advantage.
Features and Technologies
Both cards support the same suite of NVIDIA technologies, but the performance headroom of the RTX 4090 allows for more intensive use.
- DLSS 3 & Frame Generation: Both support DLSS 3 with AI-powered frame generation. The RTX 4090 can leverage this to achieve extremely high frame rates, while the RTX 4070 SUPER uses it to maintain smooth performance in demanding titles.
- Ray Tracing: The RTX 4090’s superior ray tracing performance allows for playable frame rates with path tracing in games like *Cyberpunk 2077* at 4K, whereas the RTX 4070 SUPER is better suited for high-quality ray tracing at 1440p.
- AV1 Encoding: Both include a dual AV1 encoder, beneficial for streamers and video editors for higher quality at lower bitrates.

Frequently Asked Questions (FAQ)
What is the main difference between the RTX 4090 and RTX 4070 SUPER?
The primary differences are in performance tier and target resolution. The RTX 4090 is a flagship card built for uncompromised 4K gaming and professional workloads, featuring more CUDA cores and significantly more VRAM. The RTX 4070 SUPER is a high-performance card aimed at delivering excellent 1440p gaming with higher efficiency.
Is the RTX 4090 overkill for 1440p gaming?
For standard 1440p gaming, the RTX 4090 typically delivers frame rates far beyond what standard high-refresh-rate monitors can display. It is most justified for 1440p gaming at very high refresh rates (e.g., 360Hz) or when using maximum ray tracing/path tracing settings where the extra performance is utilized.
Can the RTX 4070 SUPER handle 4K gaming?
Yes, the RTX 4070 SUPER can handle 4K gaming, particularly when using technologies like DLSS for performance upscaling. For optimal experience, settings adjustments may be necessary in the most demanding titles compared to using maximum preset graphics options.
Do both cards support the same NVIDIA features?
Yes, both graphics cards support the same core feature set from the Ada Lovelace architecture, including DLSS 3 with Frame Generation, third-generation RT Cores for ray tracing, NVIDIA Reflex, and AV1 encoding. The difference lies in the performance level at which these features can be run.
Final Thoughts
The GeForce RTX 4090 and RTX 4070 SUPER serve clearly defined roles within the GPU market.
