Asus TUF Gaming GeForce RTX 4070 Super OC Edition

Manufacturer: Asus

The Asus TUF Gaming GeForce RTX 4070 Super OC Edition is a graphics card from Asus built on Nvidia's Ada Lovelace architecture and fabricated on a 5 nm process. It operates with a base GPU clock of 1980 MHz and an OC boost clock of 2565 MHz, placing it slightly above standard non-OC variants of the same chip. The card supports ray tracing, DLSS, DirectX 12 Ultimate, and RGB lighting, and can drive up to four displays at once.

The memory configuration consists of 12GB of GDDR6X VRAM on a 192-bit bus running at an effective speed of 21,000 MHz, translating to a peak bandwidth of 504.2 GB/s. ECC memory support is included alongside Intel Resizable BAR. With 7168 shading units, 224 texture mapping units, and 80 ROPs, the card achieves a texture rate of 574.6 GTexels/s and a floating-point throughput of 36.77 TFLOPS. Output connectivity spans one HDMI 2.1a port and three DisplayPort outputs, with no USB-C, DVI, or mini DisplayPort connections present. The card has a TDP of 225W, connects via PCIe 4.0, and measures 301 mm in width and 139 mm in height, with air cooling only.

Pros
  • The OC boost clock of 2565 MHz delivers a noticeably higher turbo frequency than the standard non-OC variant of this GPU
  • Ray tracing and DLSS are both supported, enabling advanced rendering capabilities in compatible workloads
  • Up to four displays can be connected simultaneously, with one HDMI 2.1a and three DisplayPort outputs available
  • ECC memory support adds data reliability for compute-oriented or content creation tasks
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can benefit certain workloads
  • RGB lighting is included for users who prioritize visual customization in their build
Cons
  • The 192-bit memory bus width places a ceiling on maximum memory bandwidth despite the use of GDDR6X memory
  • At 301 mm in length and 139 mm in height, the card's physical footprint may not fit in compact or smaller mid-tower cases
  • No USB-C output is available, which may limit compatibility with certain modern display configurations
  • Water cooling is not supported, so users are confined to the card's built-in air cooling solution
  • XeSS (XMX) is not supported, narrowing the upscaling options available to users
Who is this for?

The Asus TUF Gaming GeForce RTX 4070 Super OC Edition is well-matched for users who prioritize ray tracing and DLSS-enabled workloads, as both features are fully supported alongside DirectX 12 Ultimate and OpenGL 4.6. The overclocked boost clock of 2565 MHz and 36.77 TFLOPS of floating-point performance make it a capable choice for demanding rendering tasks, while ECC memory support extends its relevance to compute and content creation scenarios where data integrity matters. Users who need multi-display setups of up to four screens will find the combination of one HDMI 2.1a and three DisplayPort outputs well-suited to their needs.

Who is this NOT for?

Users working with workloads that demand large VRAM allocations — such as high-resolution texture pipelines or large-scale AI inference tasks — may find the 12GB VRAM capacity a limiting factor, as such applications can exhaust available memory relatively quickly. The card's physical dimensions of 301 mm in length and 139 mm in height mean it is not a good fit for compact or small-form-factor builds, where clearance may be insufficient. Additionally, users who rely on USB-C display output or require water-cooling integration will find neither option available on this card.

Final Verdict

The Asus TUF Gaming GeForce RTX 4070 Super OC Edition is a graphics card that brings together a well-rounded specification set under the Ada Lovelace architecture, with its overclocked 2565 MHz boost clock standing out as a distinguishing characteristic within this GPU tier. Support for ray tracing, DLSS, DirectX 12 Ultimate, and up to four simultaneous display outputs gives it broad applicability across both gaming and creative workloads, while ECC memory support adds a degree of utility for compute-oriented tasks. Its larger physical footprint and the absence of USB-C output or water-cooling support are practical considerations that will matter to some users, and the 12GB VRAM ceiling is worth factoring in for the most memory-intensive workloads. Overall, the Asus TUF Gaming GeForce RTX 4070 Super OC Edition presents a coherent and capable package for users whose needs align with its strengths.
