GPU core and memory

The ASUS Dual GeForce RTX 3070 uses the NVIDIA Ampere GPU with 5888 CUDA cores. It carries 8GB of GDDR6 memory on a 256-bit bus running at 14 Gbps. The card connects through a PCI Express 4.0 slot and draws power from two 8-pin connectors. A 750W power supply is recommended.

Gaming and creative workstations

This card suits 1440p gaming and content creation workloads that fit within 8GB of video memory. It supports four simultaneous displays via two HDMI 2.1 and three DisplayPort 1.4a outputs. Builds needing more than 8GB for 4K textures or heavy compute should consider a larger frame buffer.

8GB GDDR6 frame buffer

The 8GB GDDR6 capacity is the specification that decides fit. It determines the maximum texture dataset and frame-buffer size available to the GPU. If your target resolution and asset quality exceed this limit, a card with more memory is required.

Questions about this item

How loud and hot does the DUAL-RTX3070-8G get under sustained load with its double-fan cooler?

The dual-fan design on the ASUS Dual RTX 3070 moves air across a large heatsink to manage the GPU's thermal output. Fan speed ramps with temperature, so noise rises under heavy gaming or compute workloads but stays lower at idle or light use.

What power supply and connectors does the DUAL-RTX3070-8G require to run?

This card needs a power supply of at least 750 W and two free 8-pin PCIe power cables. Without both connectors seated, the GPU will not start. Check your PSU wattage and cable count before fitting the card.

Will the DUAL-RTX3070-8G work in my older motherboard with a PCI Express 3.0 slot?

Yes. The card uses a PCI Express 4.0 interface but is fully backward compatible with PCIe 3.0 slots. It will run at 3.0 speeds, which has minimal impact on the RTX 3070's performance in most games.
