Dual RTX 3070 8GB for 1440p gaming
The ASUS Dual GeForce RTX 3070 comes with 8GB of GDDR6 memory on a 256-bit bus and 5888 CUDA cores. It targets gamers and creators who want solid frame rates at 1440p resolution. The PCI Express 4.0 interface connects to modern platforms without bandwidth limits.
Sustained load behaviour with dual fans
The card runs at a 1725 MHz boost clock in Gaming mode and 1755 MHz in OC mode while the memory operates at 14 Gbps. A dual-fan cooler moves heat away from the Ampere GPU during extended sessions so clocks stay stable rather than throttling after a short burst. The design draws power through two 8-pin connectors fed by a 750W supply.
Build quality and daily connectivity
The shroud and backplate protect the PCB during handling and fit standard ATX cases. Outputs include two HDMI 2.1 ports and three DisplayPort 1.4a connectors that drive up to four displays at 7680 x 4320 resolution. HDCP 2.3 support keeps protected content playing without handshake issues.

Questions about this item
Will this card fit in a standard mid-tower case with two 8-pin power cables available?
The card uses a dual-fan cooler and requires two 8-pin power connectors; a 750W PSU is recommended.
Can I run four monitors at 4K resolution using the available ports?
Yes, the card provides two HDMI 2.1 and three DisplayPort 1.4a outputs, supporting up to four displays at a maximum resolution of 7680 x 4320.
Is the 8GB GDDR6 memory enough for current 1440p gaming with high texture settings?
The 8GB frame buffer on a 256-bit bus at 14 Gbps delivers strong 1440p performance in modern titles when paired with the 5888 CUDA cores.
