Product identity

The ASUS Dual GeForce RTX 4070 SUPER EVO OC Edition is a 12GB GDDR6X graphics card built for 1440p gaming and content creation. It delivers a boost clock of 2550 MHz in OC mode and 2520 MHz in default mode across 7168 CUDA cores. The 192-bit memory interface runs at 21 Gbps for high bandwidth in modern titles.

Compatibility checklist

Verify that your motherboard provides a PCI Express 4.0 x16 slot and that your case can accommodate a 227 mm long, 2.5-slot thick card. The board requires a single 16-pin power connector and a power supply rated for at least 750 W. Outputs include one HDMI 2.1a and three DisplayPort 1.4a connectors for up to four displays at 7680 x 4320 resolution.

Sustained-load behaviour

A 250 W thermal design power is managed by dual axial-tech fans with 0dB technology that stop spinning under light loads. Dual ball-bearing fans increase airflow pressure while reducing long-term wear. The 2.5-slot form factor keeps the heatsink compact enough for smaller chassis without sacrificing cooling capacity during extended sessions.

Questions about this item

Does the ASUS DUAL-RTX4070S-O12G-EVO come with a power adapter or do I need to buy a 16-pin cable separately?

The card uses a single 16-pin power connector. Most modern 750W or larger power supplies include this cable natively; if your PSU only has 8-pin outputs you will need a 12VHPWR adapter, which is not included in the box.

Should I pick the OC mode at 2550 MHz or the default mode at 2520 MHz for daily gaming?

Both modes are built into the card firmware. OC mode raises the boost clock to 2550 MHz for extra headroom in heavy loads, while default mode runs at 2520 MHz with slightly lower power draw. Switch between them via GPU Tweak III or the hardware switch if present.

What does the 21 Gbps memory speed actually deliver at 1440p with DLSS 3 enabled?

The 12 GB GDDR6X running at 21 Gbps across a 192-bit bus feeds the 7168 CUDA cores enough bandwidth for high-frame-rate 1440p gaming. DLSS 3 frame generation then multiplies those frames, letting the 250 W TGP sustain smooth motion in ray-traced titles.
