Asus Dual GeForce RTX 4070 Super OC Edition

Manufacturer: Asus

The Asus Dual GeForce RTX 4070 Super OC Edition is a desktop graphics card built on NVIDIA's Ada Lovelace architecture and manufactured using a 5 nm process with 35,800 million transistors. It features 12GB of GDDR6X VRAM operating at an effective speed of 21,000 MHz across a 192-bit bus, producing a maximum memory bandwidth of 504.2 GB/s. The card supports ray tracing, DLSS, DirectX 12 Ultimate, and Intel Resizable BAR, and includes RGB lighting along with multi-display support for up to four screens simultaneously.

The Asus Dual RTX 4070 Super OC Edition runs at a base GPU clock of 1,980 MHz with a boost clock of 2,520 MHz, delivering 36.13 TFLOPS of floating-point performance. Its 7,168 shading units are paired with 224 texture mapping units and 80 render output units, yielding a texture rate of 564.5 GTexels/s and a pixel rate of 201.6 GPixel/s. With a TDP of 220W, the card connects via PCIe 4.0 and measures 267 mm in length and 133.9 mm in height, relying on air cooling. Output options include one HDMI 2.1a port and three DisplayPort outputs, with no DVI, mini DisplayPort, or USB-C connections present.

Pros
  • At 267 mm in length, the card fits into a wider range of mid-tower and compact cases than many full-length graphics cards
  • A 220W TDP places relatively modest demands on system power delivery, giving more flexibility in power supply selection
  • Supports up to four simultaneous displays via three DisplayPort outputs and one HDMI 2.1a port, covering a wide range of multi-monitor configurations
  • Ray tracing and DLSS are both supported natively, enabling compatibility with modern rendering and upscaling techniques
  • ECC memory support adds error detection and correction capability, which is useful for compute workloads requiring data integrity
  • Double Precision Floating Point (DPFP) support extends the card's usability beyond gaming into numerical and scientific compute tasks
Cons
  • The boost clock of 2,520 MHz is lower than some other cards built on the same GPU architecture, which can affect peak throughput in GPU-limited scenarios
  • No USB-C output is available, limiting direct connectivity to displays or devices that require that interface
  • Water cooling is not supported, so thermal performance depends entirely on the air cooling solution
  • The 192-bit memory bus restricts potential memory bandwidth scaling compared to wider bus configurations
  • XeSS (XMX) is not supported, narrowing upscaling options to DLSS only
Who is this for?

This card is a practical fit for users working with mid-tower or compact builds, as its 267 mm length and 220W TDP make it easier to accommodate within tighter cases and less demanding power configurations. Gamers who want to take advantage of ray tracing and DLSS in modern titles will find the necessary hardware support in place, while the inclusion of ECC memory and DPFP support also makes it a reasonable choice for users who occasionally run compute or numerical workloads alongside their primary graphics tasks. The four-display output capability further suits those managing multi-monitor setups without needing additional hardware.

Who is this NOT for?

Users who push hardware to its limits in heavily GPU-bound scenarios may find the 2,520 MHz boost clock and 36.13 TFLOPS of floating-point throughput insufficient for the most demanding workloads at very high resolutions or with all quality settings maximized. Those with displays or peripheral devices that rely on USB-C connectivity will need to factor in the complete absence of that port type, as no adapter solution is built in. Additionally, users interested in liquid cooling integration will need to look at alternative cards, since water cooling is not supported and the card depends entirely on its air cooler for thermal management.
