ASUS Dual RTX 5070 12GB GDDR7 Graphics Card

The ASUS Dual GeForce RTX 5070 is a 12GB graphics card built on the Blackwell architecture. It connects via a PCI Express 5.0 x16 interface and delivers 6144 CUDA cores with a boost clock of 2572 MHz in OC mode. The 192-bit memory bus runs GDDR7 at 28 Gbps for high bandwidth.

Ideal for 1440p Gaming and DLSS 4.0 Workloads

This card suits gamers targeting high-refresh 1440p play and creators using DLSS 4.0 features. The 12GB frame buffer and 192-bit bus may limit 4K ultra texture packs or heavy VRAM workloads. Builders needing more memory or a wider bus should consider higher-tier models.

Requires 750W PSU and 16-Pin Power Connector

A 750W power supply is recommended alongside a single 16-pin power connector. The 2.5-slot, 249mm ATX form factor fits most mid-tower cases. Verify case clearance and PSU cabling before purchase.

Questions about this item

How do I install the 16-Pin power connector on this 2.5-slot card without bending cables?

Route the included 1-to-2 adapter cable before seating the 249 mm long card, keep the 16-Pin plug straight and avoid sharp bends near the 50.6 mm thick cooler.

What maintenance will the dual-fan cooler need after extended use?

Clean dust from both fans and the heatsink fins every few months using compressed air; the 2.5-slot shroud traps debris that reduces airflow over the GDDR7 memory.

At what point does the 192-Bit memory interface become the bottleneck in sustained 4K workloads?

The 28 Gbps GDDR7 bandwidth saturates first during prolonged 7680 x 4320 rendering, limiting frame rates before the 6144 CUDA cores reach thermal limits.
