ASUS ROG Strix RTX 5070 OC 12GB identity

The ASUS ROG Strix GeForce RTX 5070 OC 12GB GDDR7 graphics card delivers NVIDIA Blackwell architecture with 6144 CUDA cores and 12GB of 192-Bit GDDR7 memory running at 28 Gbps. It connects through a PCI Express 5.0 x16 interface and drives up to four displays via two HDMI 2.1b and three DisplayPort 2.1b outputs at a maximum resolution of 7680 x 4320.

Upgrade from 8GB cards when VRAM limits appear

Moving from an 8GB card to this 12GB model removes the memory ceiling that forces texture downgrades at 1440p ultra or 4K high settings. The faster GDDR7 memory and newer architecture also lift frame rates in titles that use DLSS 4.0, making the jump worthwhile when current VRAM usage regularly hits the 8GB limit.

Built for 1440p high refresh and entry 4K

This card suits gamers targeting 1440p high refresh rates or entry-level 4K gaming with DLSS 4.0 upscaling. Users who need more than 12GB for heavy 4K texture packs, professional 3D rendering, or multi-monitor 4K workloads should look at higher VRAM options instead.

Questions about this item

Will the 2.5-slot ROG Strix RTX 5070 fit in a case with 320 mm GPU clearance?

The card uses a 2.5-slot design, so verify your case lists at least 320 mm of graphics-card length and enough width for the cooler.

Which power cables must be connected before the first boot?

Attach the single 12VHPWR connector fully seated; the card will not start if it detects only a partial insertion.

How often should the three axial-tech fans be cleaned?

Blow dust from the fan blades and heatsink fins every six months to keep airflow consistent.
