12GB GDDR6X graphics card

The ASUS ROG Strix GeForce RTX 4070 SUPER delivers 12GB of GDDR6X memory on a 192-bit interface with a 21 Gbps effective clock. It targets gamers and creators who need high frame rates at 1440p or entry 4K. The PCIe 4.0 board runs at a 2475 MHz core clock and a 2505 MHz boost clock across 7168 CUDA cores. DirectX 12 and OpenGL 4.6 support cover modern APIs.

GPU Tweak III utility

The bundled GPU Tweak III software provides performance tweaking, thermal controls and system monitoring in one interface. It lets you adjust clocks, voltages and fan curves without leaving the desktop. The utility also logs sensor data so you can review thermals after a session. No separate driver package is required beyond the standard NVIDIA download.

Diecast frame with vented backplate

A diecast shroud, frame and backplate add structural rigidity while the vented backplate lets hot air escape toward the case exhaust. The 3.12-slot design houses a massive fin array fed by three Axial-tech fans scaled for 31% more airflow. Digital power control uses high-current power stages and 15K capacitors for stable delivery. Outputs include one HDMI 2.1 and three DisplayPort 1.4a connectors for up to four displays at 7680 x 4320.

Questions about this item

How often should the three Axial-tech fans and the vented backplate be cleaned to maintain airflow?

Dust the three Axial-tech fans and the vented backplate every few months with compressed air to keep the 31 % airflow gain effective.

Which specification caps sustained performance first, the 192-bit memory interface or the 12 GB GDDR6X buffer?

The 192-bit interface limits memory bandwidth to 21 Gbps, so it becomes the bottleneck before the 12 GB capacity fills.

What happens to fan noise and thermals when the card runs at the 2505 MHz boost clock all day?

The 3.12-slot fin array and three Axial-tech fans move 31 % more air, keeping temperatures lower and fan speeds quieter during extended loads.
