ASUS TX RTX 5070 OC 12GB GDDR7

The ASUS TX GeForce RTX 5070 OC is a graphics card built on the NVIDIA GeForce RTX 50 Series architecture. It delivers 6144 CUDA cores and 12GB of GDDR7 memory across a 192-bit interface clocked at 28 Gbps. The board connects via PCI Express 5.0 x16 and supports DirectX 12 Ultimate with OpenGL 4.6.

Suited for 1440p high-refresh and entry 4K gaming

This card fits builders targeting 1440p at high frame rates or 4K with DLSS 4 upscaling. The 12GB frame buffer handles modern texture packs at those resolutions. Users chasing native 4K ultra without upscaling or heavy VRAM workloads such as large-language-model inference should consider cards with wider buses and larger memory pools.

12GB GDDR7 headroom for current titles

The 12GB GDDR7 buffer comfortably runs current AAA games at 1440p ultra and 4K with quality-mode upscaling. At native 4K with maximum texture settings the 192-bit bus and 12GB capacity become the limiting factor, so frame pacing may dip in the most demanding scenes. Multi-monitor productivity up to 7680 x 4320 is supported across two HDMI 2.1b and three DisplayPort 2.1b outputs.

Questions about this item

What motherboard slot does the TX-RTX5070-O12G need to run at PCI Express 5.0 x16?

A PCI Express 5.0 x16 slot on the motherboard is required for full bandwidth.

Will the RTX 5070 work in an older board that only has PCI Express 4.0 or 3.0?

Yes, the card is backward compatible and will operate at the slot's maximum speed.

How can I verify the 12 GB GDDR7 memory is running at the rated 28 Gbps effective clock?

GPU-Z or similar tools will show the memory clock at 28 Gbps when the driver is loaded.
