The ASUS Dual GeForce RTX 4070 SUPER EVO OC is a desktop graphics card built around NVIDIA's RTX 4070 SUPER GPU, with 12GB of GDDR6X memory. It is meant for gaming and creative work in a desktop PC, and it uses a two-fan cooler designed to keep noise down at light loads. Here is what the main specs mean in practice.
The GPU and its memory
The card is based on NVIDIA's Ada Lovelace architecture, which ASUS describes as ultra-efficient. It carries 12GB of GDDR6X video memory. Video memory holds textures, frame buffers and other data the GPU needs close at hand, so more of it generally helps at higher resolutions and with detailed textures. The card connects to the motherboard over PCIe 4.0, the standard on most recent desktop boards. PCIe is backward compatible, so a card like this will typically also work in an older slot, though the link may run at a lower speed.
What DLSS 3 and ray tracing add
The listing highlights NVIDIA DLSS 3 and full ray tracing. DLSS is an AI-based technique that renders a game at a lower internal resolution and reconstructs a sharper image, and DLSS 3 can also generate extra frames. ASUS quotes up to four times the performance with DLSS 3 compared with brute-force rendering, using the card's 4th generation Tensor Cores. These figures are the brand's own, and the gain depends on the game, since only titles that support DLSS can use it.
Ray tracing simulates how light behaves in a scene, producing more realistic reflections, shadows and lighting. The card's 3rd generation RT Cores handle that work, and ASUS says they offer up to twice the ray tracing performance of the previous generation.
Clock speeds and the OC edition
"OC" means the card is factory overclocked. ASUS lists a boost clock of 2550 MHz in OC Mode and 2520 MHz in Default Mode. The difference between the two is small, and the boost clock is the speed the GPU can reach under load, not a constant figure. Real results depend on temperatures, power limits and the game or application.
Cooling and the 0dB fan mode
The card uses ASUS's Axial-tech fan design. The fan has a smaller hub, which leaves room for longer blades, and a barrier ring that increases downward air pressure. ASUS also mentions dual ball-bearing fans, which it says support longevity and durability. The 0dB technology means the fans typically stop spinning when the card is under light load, such as web browsing, and start up once temperatures rise.
Ports and physical size
The listing names HDMI 2.1a and DisplayPort 1.4a outputs. HDMI 2.1 is the version used for high-resolution, high-refresh-rate televisions and monitors. The card has a 2.5-slot design and measures about 14.5 x 8.8 x 2.8 inches (about 37 x 22 x 7 cm), with a weight of 1.5 lb (about 0.7 kg). A cooler of this thickness occupies more than two expansion slots on the back of the case.
Who it suits
It suits people building or upgrading a desktop PC for gaming with DLSS and ray tracing, and those who want a card with a quiet idle mode. ASUS positions it for a PC build that needs strong graphics performance.
What to check before you buy
- Case clearance: confirm your case has room for a card about 14.5 inches long and 2.5 slots thick.
- Power supply: check the card's power requirements in the manual against your power supply's wattage and the connectors it provides.
- Motherboard slot: you need a free PCIe x16 slot; check which PCIe generation your board supports.
- Monitor connections: make sure your display has an HDMI or DisplayPort input to match.
- Airflow: good case ventilation helps any graphics card keep its temperatures in check.
- Software: DLSS 3 and ray tracing only apply in games and applications that support them.
