Ready for 1440p gaming

The GIGABYTE GeForce RTX 4070 Gaming OC V2 delivers 12GB of GDDR6X memory across a 192-bit bus. It targets enthusiasts who want high frame rates at 1440p resolution. The Ada Lovelace architecture supports DLSS 3 and hardware ray tracing. A factory overclock pushes the effective memory clock to 21000 MHz.

Check power and space first

Your motherboard needs a free PCI Express 4.0 x16 slot and the case must clear a 300 mm card that occupies 2.5 slots. The board draws 150W through a single 8-pin connector so a 650W power supply is the minimum recommendation. Verify your chassis length and PSU cables before ordering.

Triple-fan cooling with metal backplate

The WINDFORCE cooler uses three fans to move heat away from the GPU core and memory. A protection metal backplate stiffens the PCB and helps prevent sag over time. An anti-sag bracket is included for extra support. Outputs comprise one HDMI and three DisplayPort connectors for up to four displays.

Questions about this item

Does the GV-N4070GAMING OCV2-12GD come with the 8-pin power cable or must I buy it separately?

The card requires one 8-pin connector from your power supply; the cable is not included in the box.

The model name shows 12GB GDDR6X on a 192-bit bus — is that the only memory option for this SKU?

Yes, this SKU is fixed at 12GB GDDR6X with a 192-bit interface; no other capacity or bus width exists for the GV-N4070GAMING OCV2-12GD.

What does the 21000 MHz memory clock actually deliver once the card is installed in a PCI Express 4.0 x16 slot?

The 21 Gbps GDDR6X memory feeds the 4070 GPU at full bandwidth over the 192-bit bus, enabling the 7680 x 4320 maximum resolution across four displays.
