ASUS ROG Strix RTX 4070 12GB GDDR6X graphics card

The ASUS ROG Strix GeForce RTX 4070 features 12GB of GDDR6X memory on a 192-bit interface with an effective clock of 21000 MHz. It runs on the NVIDIA Ada Lovelace architecture with 5888 CUDA cores and a 2505 MHz core clock. The card connects via PCI Express 4.0 and supports DirectX 12 and OpenGL 4.6 for modern gaming and creative workloads.

Target users and alternatives

This bundle suits owners of gaming laptops, handhelds such as ROG Ally or Steam Deck, Intel-based Macs and mini PCs that have an OCuLink or USB4 port and want desktop-class graphics without opening the host chassis. Users whose systems lack those high-speed ports or who already have a full-size desktop with internal PCIe slots should look at a standard internal graphics card instead.

Bundled dock and power supply impact

The UGREEN CM980 LinkStation eGPU dock adds dual OCuLink 64Gbps and USB4 40Gbps interfaces with an industry-low 3-13% performance loss over native PCIe 4.0 x4. Its built-in 850W ATX 3.1 80+ Gold PSU provides a native 12VHPWR connector rated for 600W and handles 200% transient spikes. The USB4 port also delivers 100W PD reverse charging so the host device stays powered during use.
