ASUS TUF Gaming RTX 5070 12GB GDDR7

This ASUS TUF Gaming GeForce RTX 5070 OC graphics card delivers 12GB of GDDR7 memory on a 192-bit interface with an effective 28 Gbps clock. The Blackwell architecture provides 6144 CUDA cores and supports DirectX 12 Ultimate plus OpenGL 4.6. A PCI Express 5.0 x16 link feeds the GPU, which boosts to 2640 MHz in OC mode or 2610 MHz in default mode. Three DisplayPort 2.1b and two HDMI 2.1b outputs drive up to four displays.

Who this suits and who should look elsewhere

The 12GB frame buffer and 6144 cores suit 1440p high-refresh gaming and entry-level 4K with DLSS 4.0 upscaling. Content creators gain hardware AV1 encode and decode plus CUDA acceleration in supported apps. Builders needing more VRAM for heavy 4K textures or professional GPU compute should consider cards with larger memory buffers. Systems limited to PCIe 4.0 will still work but lose the full 5.0 x16 bandwidth.

Build integration — power, space and connectivity

A single 16-pin 12VHPWR connector supplies power, so the PSU must provide that cable or a certified adapter. The PCIe 5.0 x16 slot requires a compatible motherboard and CPU platform for maximum throughput. Three DisplayPort 2.1b and two HDMI 2.1b ports free up motherboard video outputs and support multi-monitor layouts without adapters. The dual-slot bracket keeps adjacent expansion slots available for add-in cards.

Questions about this item

What power connectors does the RTX 5070 need from my PSU?

The card draws power through a 12VHPWR connector; ensure your supply includes one or provides a native 12V-2x6 cable rated for the GPU's power target.

Will the PCI Express 5.0 x16 card run at full speed in my PCIe 4.0 motherboard slot?

Yes, the interface is backward compatible; the RTX 5070 will operate at PCIe 4.0 x16 speeds with negligible bandwidth impact on the 12GB GDDR7 frame buffer.

How can I verify the boost clock is hitting 2640 MHz in OC mode after installation?

Open GPU-Z or the ASUS GPU Tweak III overlay while running a 3D load; the sensors tab should report a boost frequency at or near 2640 MHz when the OC profile is active.
