TUF Gaming GeForce RTX 4070 12GB

The ASUS TUF Gaming GeForce RTX 4070 O12G is a 12GB GDDR6X graphics card built for 1440p gaming and creative workloads. It uses the NVIDIA GeForce RTX 40 Series chipset with 5888 CUDA cores and a 192-bit memory interface. The card connects via PCI Express 4.0 and supports up to four displays through HDMI 2.1 and three DisplayPort 1.4a outputs.

Boost clock 2580 MHz sustained load

The GPU boost clock reaches 2580 MHz while the 12GB GDDR6X memory runs at an effective 21000 MHz across the 192-bit bus. This configuration delivers consistent frame rates in extended sessions rather than only brief peaks. The TUF cooling design maintains thermal stability so the processor can hold higher frequencies for longer periods during demanding titles or rendering tasks.

PCI Express 4.0 x4 eGPU interface limits

When installed in an eGPU dock using an OCuLink PCIe 4.0 x4 link the card sees a 3-13 percent performance loss compared to a direct motherboard slot. The 64Gbps OCuLink bandwidth is far closer to native throughput than the 40Gbps USB4 alternative which typically incurs 20-30 percent loss. A dock with an 850W ATX 3.1 supply and native 12VHPWR connector can handle 200 percent transient spikes up to 600W for stable power delivery.

Questions about this item

Will the card fit inside the UGREEN CM980 dock without an extra power adapter?

The dock includes an 850W ATX 3.1 power supply with a native 12VHPWR connector that supports up to 600W GPUs, so no separate adapter is needed.

What display outputs does the graphics card provide for multi-monitor setups?

The card offers one HDMI 2.1 port and three DisplayPort 1.4a outputs, supporting up to four monitors at a maximum resolution of 7680 x 4320.

How much performance loss should I expect when using the OCuLink connection versus a desktop slot?

The manufacturer states an industry-low 3-13% performance loss over the PCIe 4.0 x4 OCuLink link, compared with 20-30% typical for Thunderbolt-only docks.
