KFA2 GeForce RTX 4070 Super 1-Click OC 2X

Manufacturer: KFA2

The KFA2 GeForce RTX 4070 Super 1-Click OC 2X is a graphics card built on the Ada Lovelace architecture, fabricated on a 5 nm process with 35,800 million transistors. It carries 12GB of GDDR6X memory running at an effective 21,000 MHz across a 192-bit bus, providing up to 504 GB/s of memory bandwidth, and connects to the host system via PCIe 4. The card supports up to four simultaneous displays through one HDMI 2.1a port and three DisplayPort outputs.

The GPU runs at a base clock of 1980 MHz with a boost up to 2475 MHz, supported by 7,168 shading units, 224 texture mapping units, and 80 render output units, translating to a texture rate of 554.4 GTexels/s and a pixel rate of 198 GPixel/s. Ray tracing, DLSS, and DirectX 12 Ultimate are all supported, with the feature set also including OpenGL 4.6, OpenCL 3, Intel Resizable BAR, ECC memory, DPFP, stereoscopic 3D, RGB lighting, and multi-display technology. The card operates within a 220W TDP, relies on air cooling only, and measures 252 mm in width by 131 mm in height.

Pros
  • A 220W TDP keeps power draw relatively contained, placing a moderate demand on system power delivery and case airflow
  • At 252 mm wide and 131 mm tall, the card's physical dimensions are manageable and compatible with a wider range of cases than larger models
  • Ray tracing and DLSS support are both present, enabling compatible rendering workloads without additional hardware
  • ECC memory and DPFP support make the card useful for compute tasks where data precision and integrity are relevant alongside graphics work
  • RGB lighting is included, offering visual customization within a system build
  • Intel Resizable BAR is supported, allowing the CPU to access the full GPU memory pool more efficiently during operation
Cons
  • The 192-bit memory bus limits peak bandwidth to 504 GB/s, which may be a constraint in highly memory-intensive workloads
  • 12GB of VRAM may prove limiting for use cases at higher resolutions where a larger framebuffer would be beneficial
  • Liquid or hybrid air-water cooling is not supported, leaving thermal management entirely dependent on air cooling within the system
  • XeSS (XMX) upscaling is absent, limiting compatibility with workflows or titles that rely on that specific technology
Who is this for?

This card suits users who want a capable discrete graphics solution without the physical and power overhead of larger models — its 252 mm width and 220W TDP make it a practical fit for mid-tower and some compact builds where space and power headroom are real considerations. Ray tracing, DLSS, ECC memory, and DPFP support give it enough range to serve users who occasionally shift between graphics and compute-adjacent workloads, while the four-display output capacity covers most multi-monitor productivity or gaming setups without additional hardware. Those who value RGB lighting for system aesthetics will also find that feature present without needing a separate add-on.

Who is this NOT for?

Users whose workloads push against memory limits will find the 12GB of VRAM on a 192-bit bus a potential constraint, particularly at higher resolutions or in scenarios where a wider bandwidth pipeline and larger framebuffer would make a meaningful difference. Since liquid or hybrid cooling is not supported, those operating in thermally demanding environments or building systems designed around water cooling will need to look at other options. The card also lacks XeSS (XMX) support, making it unsuitable for workflows or titles that depend on that specific upscaling technology.

PCI Express (PCIe) version 4
semiconductor size 5 nm
number of transistors 35800 million
Has air-water cooling ✕
width 252 mm
height 131 mm

The card is grounded in the Ada Lovelace architecture, built on a 5 nm process with 35,800 million transistors, and connects to the host system through a PCIe 4 interface. Its Thermal Design Power is rated at 220W, and cooling is handled by air only, as liquid or hybrid air-water cooling is not supported. The card's dimensions of 252 mm in width and 131 mm in height give it a relatively manageable physical footprint for a modern discrete graphics card.

Final Verdict

The KFA2 GeForce RTX 4070 Super 1-Click OC 2X is a compact, moderately powered graphics card that puts together a well-rounded feature set within a restrained physical and thermal envelope. Its 220W TDP and 252 mm footprint make it genuinely accessible to builders working with tighter case constraints, while ray tracing, DLSS, ECC memory, DPFP, and four-display output capability ensure it covers a meaningful range of graphics and compute use cases. Users with demanding memory bandwidth requirements or a preference for liquid cooling will find some limitations in its specification profile, but for those whose needs align with what it offers, the KFA2 GeForce RTX 4070 Super 1-Click OC 2X delivers a practical and feature-complete package without unnecessary bulk.
