Dual RTX 4070 Super 12 GB for 1440p and 4K gaming

This ASUS Dual graphics card uses the NVIDIA GeForce RTX 4070 SUPER GPU with 7168 CUDA cores and 12 GB of GDDR6X memory on a 192-bit bus. The factory OC mode lifts the boost clock to 2550 MHz while the default mode runs at 2520 MHz. It targets enthusiasts who want high frame rates at 1440p and playable 4K performance with DLSS 3.

PCIe 4.0 slot 750 W PSU and 16-pin power connector

Verify that your motherboard provides a full-length PCI Express 4.0 x16 slot and that the case can accommodate a card 267 mm long. The board draws up to 250 W and requires a single 16-pin power connector, so a 750 W power supply is the minimum recommended capacity. Check clearance for the 2.56-slot thickness and the 10.51-inch length before ordering.

Axial-tech fans 0dB mode and dual ball bearings

The cooler uses two Axial-tech fans with a smaller hub, longer blades and a barrier ring that increases downward air pressure. Dual ball fan bearings are rated to last up to twice as long as sleeve designs. A 0dB technology stops the fans completely under light loads for silent operation, while the 2.56-slot form factor keeps the heatsink dense without exceeding standard ATX mounting holes.

Questions about this item

What comes in the box with the DUAL-RTX4070S-O12G and what must I buy separately?

The card includes the GPU with dual axial-tech fans, 2.56-slot bracket, 16-pin power connector and four display outputs. You must supply a 750W PSU, PCIe 4.0 motherboard slot and case clearance for a 267 mm long card.

Should I choose the 2520 MHz default or 2550 MHz OC mode on this 12GB model?

Default mode runs at 2520 MHz boost for standard thermals; OC mode raises boost to 2550 MHz for higher frame rates if your cooling and 750W PSU headroom allow it.

What does the 21 Gbps GDDR6X figure mean once the card is installed?

The 21000 MHz memory clock feeds the 192-bit bus at 21 Gbps, giving the 7168 CUDA cores high bandwidth for 4K textures and DLSS frame generation without memory bottlenecks.
