How They Compare
These two cards sit in the same performance class for 1440p, but they approach it with different architectures, memory technology, and board designs. The ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 brings Blackwell features and a modern cooler, while the RTX 4070 Super relies on the previous Ada generation that owners commonly report as efficient and well balanced for 1440p.
Architecture and Feature Set
The ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 is powered by the NVIDIA Blackwell architecture and DLSS 4 per the spec sheet, which gives you access to the newest upscaling and frame generation features. That matters if you play demanding ray traced titles at 1440p and want to keep frame rates high without lowering settings. The RTX 4070 Super, by contrast, is based on the prior generation and supports DLSS 3, which owners commonly report as strong but without the latest Blackwell specific enhancements.
When you compare the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 and the RTX 4070 Super side by side, the practical difference is longevity of feature support. If you tend to keep a GPU for three to four years, the newer architecture and DLSS 4 pipeline of the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 offers a longer runway for future games that lean on AI upscaling. If you upgrade more frequently or play mostly competitive shooters where you prioritize low latency over ray tracing, the RTX 4070 Super remains a capable and well supported option.
VRAM and Memory Technology
Per the spec sheet, the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 comes with 12GB of GDDR7 memory on a PCIe 5.0 interface, which provides higher memory bandwidth and improved efficiency compared to the previous generation. That memory setup is well matched to 1440p ultra textures and helps when you enable ray tracing or use high resolution texture packs. For a deeper look at how current 1440p cards handle memory heavy titles, see our top RTX 5070 ti cards for 1440p gaming guide.
The RTX 4070 Super also ships in a 12GB class configuration that owners commonly report as sufficient for most 1440p games today, but it uses previous generation memory technology. In practice, both the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 and the RTX 4070 Super give you enough VRAM for 1440p, yet the GDDR7 on the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 is the more future facing choice if you plan to hold the card while games continue to increase texture demands. Neither card is aimed at heavy 4K texture workloads where larger VRAM pools would be preferred.
Power Draw and PSU Requirements
Power and thermal behavior are important for 1440p builds where you want quiet operation under load. The ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 is described as using a phase change GPU thermal pad and an optimized heatsink layout to improve heat transfer, which helps keep temperatures lower for sustained performance. You should still follow the GPU maker recommended wattage for your total system and leave headroom over the combined CPU and GPU draw, and you should use the correct PCIe power connectors specified for your unit.
Owners commonly report that the RTX 4070 Super is an efficient card for its class and often runs well on a quality 650W to 750W class power supply depending on your CPU, while the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 will have similar expectations but benefits from newer power management tied to Blackwell. When you evaluate the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 versus the RTX 4070 Super, do not assume either card can run on an undersized or low quality unit, and never claim a single PSU handles any configuration. Check your PSU rating, cable capacity, and case airflow, and follow the manufacturer mounting and power instructions carefully.
Size, Cooling and Case Fit
Physical fit is where the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 stands out clearly on paper. It uses a 2.5 slot design with three Axial tech fans that feature a smaller hub, longer blades, and a barrier ring to increase downward air pressure, and it is marketed as SFF Ready for small form factor builds. The shroud, heatsink, and heat pipes are arranged to take advantage of side panel ventilation, and the card includes Dual BIOS support. That combination makes it easier to fit into compact cases where clearance is tight, though you should still verify GPU length, slot thickness, and cooler height against your case spec sheet.
The RTX 4070 Super is available in a wide range of board designs, and owners commonly report that many models are also 2.5 slot to 3 slot with dual or triple fan coolers, but SFF Ready branding is not universal across all variants. If you are working in a tight ITX or micro ATX case, the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 gives you a clearer compatibility story out of the box, while the RTX 4070 Super may require more careful measurement of length and thickness.

Which One Should You Get
Choose the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 if you want the newest architecture, DLSS 4 support, and a cooler that is explicitly designed for small form factor compatibility. It is a strong fit for a fresh 1440p high refresh build where you plan to keep the card for several years, play ray traced titles, and value a 2.5 slot triple fan design with Dual BIOS and a phase change thermal pad for consistent thermals. You will also appreciate its PCIe 5.0 interface and 12GB GDDR7 if you want the most current memory technology without stepping up to a higher tier card.
Choose the RTX 4070 Super if you prefer a proven Ada based option that owners commonly report as efficient and well balanced for 1440p, and if you find a board design that matches your case and power supply at a more approachable overall system cost. It suits builders who prioritize value for high refresh esports and AAA titles at 1440p without needing the very latest upscaling features, or who already have a well ventilated mid tower where SFF Ready certification is less critical. If your monitor is 1440p 144Hz to 180Hz and you upgrade every two generations, the RTX 4070 Super remains a sensible choice.
Who Should Skip Both
Both cards are not ideal for builders who need true 4K ultra performance, heavy creative workloads that benefit from larger VRAM, or ultra compact low power systems with strict thermal limits. If you are aiming for 4K 120Hz with max ray tracing, or you work with large video or 3D projects that benefit from more than a 12GB class frame buffer, neither the ASUS SFF-Ready Prime NVIDIA GeForce RTX 5070 nor the RTX 4070 Super is the right choice and you should consider a higher tier GPU. They are also not a good fit if your case cannot accommodate a 2.5 slot triple fan cooler or your power supply lacks the recommended headroom and connectors.
