KFA2 GeForce RTX 4070 Super EX Gamer 1-Click OC

Manufacturer: KFA2

The KFA2 GeForce RTX 4070 Super EX Gamer 1-Click OC is a graphics card from KFA2 built on NVIDIA's Ada Lovelace architecture, produced on a 5 nm process with 35,800 million transistors. It features a relatively compact physical footprint at 252 mm in length and 131 mm in height, and includes RGB lighting. With a 220W Thermal Design Power (TDP) and PCIe 4.0 connectivity, it fits within a broad range of mid-to-full-size desktop system configurations.

The card is equipped with 12GB of GDDR6X VRAM on a 192-bit memory bus, running at an effective speed of 21,000 MHz and delivering up to 504 GB/s of memory bandwidth. Its 7,168 shading units, 224 texture mapping units, and 80 render output units produce a floating-point performance of 36.77 TFLOPS, a texture rate of 574.6 GTexels/s, and a pixel rate of 205.2 GPixel/s, with a boost clock of 2,565 MHz. The card supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3.0, ray tracing, DLSS, stereoscopic 3D, ECC memory, and Intel Resizable BAR, while XeSS (XMX) and LHR are not included. Display output consists of three DisplayPort and one HDMI 2.1a port, supporting up to four monitors simultaneously, with no USB-C, DVI, or mini DisplayPort connections available.

Pros
  • At 252 mm in length and 131 mm in height, the card's compact dimensions make it easier to fit into a wider range of cases, including builds where card length is a limiting factor
  • A boost clock of 2,565 MHz and 36.77 TFLOPS of floating-point performance indicate a solid compute throughput for its specification tier
  • Ray tracing, DLSS, and DirectX 12 Ultimate support are all present, covering the full set of modern rendering features
  • ECC memory support provides error detection and correction, which benefits workloads where memory data integrity matters
  • Intel Resizable BAR support enables more efficient CPU access to the full GPU frame buffer during operation
  • Four display outputs — three DisplayPort and one HDMI 2.1a — allow for flexible multi-monitor configurations
Cons
  • The 192-bit memory bus width places an upper ceiling on memory throughput scalability compared to wider-bus configurations
  • No USB-C output is available, which limits compatibility with monitors or adapters that rely on that connection
  • Air-water cooling is not supported, ruling out liquid cooling setups for users who prefer or require that option
  • With a 220W TDP, the card's power demands may require attention to the overall power supply capacity of the host system
Who is this for?

The card's compact 252 mm x 131 mm form factor makes it particularly well-suited to users building in smaller or mid-tower cases where card length is a genuine constraint, without sacrificing support for ray tracing, DLSS, and DirectX 12 Ultimate. Its 12GB of GDDR6X VRAM with 504 GB/s of bandwidth and a 2,565 MHz boost clock are well-matched to users who engage in graphically demanding gaming or content workloads at a level where memory capacity and throughput are meaningful factors. ECC memory support also makes it a reasonable fit for those running compute-sensitive tasks where memory data integrity is a practical requirement.

Who is this NOT for?

Users who rely on USB-C display connectivity will find this card incompatible out of the box, as no USB-C output is present. The 192-bit memory bus may also be a limiting factor for workloads that push sustained memory throughput to its upper bounds, making the card less suited to highly memory-bandwidth-intensive applications. Additionally, the absence of air-water cooling support means the card is not a fit for users who want to integrate it into a custom liquid cooling loop, as they would have no supported path to do so with this model.

Grounded in the Ada Lovelace architecture and built on a 5 nm process, the card packs 35,800 million transistors into a physical footprint of 252 mm in width and 131 mm in height — a notably compact size for its specification class. It carries a 220W TDP and uses a PCIe 4.0 interface, while air-water cooling is not supported, leaving the card dependent on its built-in air cooling solution.

Final Verdict

The KFA2 GeForce RTX 4070 Super EX Gamer 1-Click OC occupies a well-defined position in the graphics card market, pairing a compact 252 mm form factor with 12GB of GDDR6X VRAM, a 2,565 MHz boost clock, and a full suite of modern rendering features including ray tracing, DLSS, and DirectX 12 Ultimate. Its smaller footprint makes it genuinely accessible to a wider range of build configurations, while ECC memory support and Intel Resizable BAR add practical utility beyond standard gaming use. The trade-offs — a 192-bit bus, no USB-C output, and no liquid cooling support — are worth weighing depending on the intended workload and system setup. For users prioritizing a capable, space-conscious graphics card with a comprehensive feature set, the KFA2 GeForce RTX 4070 Super EX Gamer 1-Click OC is a coherent and well-rounded option.
