KFA2 GeForce RTX 4080 Super SG 1-Click OC

Manufacturer: KFA2

The KFA2 GeForce RTX 4080 Super SG 1-Click OC is a graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process and housing 45,900 million transistors. It features a base GPU clock of 2295 MHz with a boost up to 2610 MHz, alongside support for ray tracing, DLSS, and RGB lighting, making it a fully featured option within the RTX 4080 Super lineup.

On the memory side, the card carries 16GB of GDDR6X across a 256-bit bus, reaching an effective speed of 23,000 MHz and delivering up to 736.3 GB/s of bandwidth. Its 10,240 shading units, 320 TMUs, and 112 ROPs contribute to a texture rate of 835.2 GTexels/s and a pixel rate of 292.3 GPixel/s. The card has a TDP of 320W, measures 352 mm in length and 153 mm in height, and provides connectivity through one HDMI 2.1a port and three DisplayPort outputs, with support for up to four displays simultaneously.

Pros
  • With 16GB of GDDR6X memory on a 256-bit bus delivering up to 736.3 GB/s of bandwidth, the card handles large textures and memory-intensive workloads without running short on VRAM
  • Ray tracing and DLSS support are both included, enabling hardware-accelerated rendering and AI-based upscaling in compatible applications
  • ECC memory support adds data integrity protection, which is useful for compute tasks where memory errors could affect output accuracy
  • The card can drive up to four displays simultaneously through its three DisplayPort outputs and one HDMI 2.1a port, offering flexible multi-monitor setups
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer at once, which can reduce data transfer bottlenecks in supported systems
  • RGB lighting is built into the card for users who prioritize visual customization within their build
Cons
  • A TDP of 320W places significant demand on the power supply, requiring a well-specified PSU and adequate case airflow
  • At 352 mm in length and 153 mm in height, the card's physical footprint may not fit in compact or mid-tower cases with limited clearance
  • There is no USB-C output, which limits direct connectivity to displays or devices that rely on that port type
  • Air-water cooling is not supported, so users seeking liquid cooling integration will need a separate solution
  • XeSS (XMX) is not supported, restricting access to that upscaling technology for users who rely on it
Who is this for?

This card suits users who run ray tracing and DLSS-enabled workloads, where hardware acceleration and AI upscaling can be fully leveraged. Its 16GB of GDDR6X memory and 736.3 GB/s of bandwidth also make it a practical fit for GPU compute tasks requiring large memory allocations, especially given ECC support that benefits users where data accuracy matters. Those running multi-monitor setups of up to four displays will find the port configuration accommodating, and the Intel Resizable BAR support adds further utility for users on compatible PCIe 4 platforms.

Who is this NOT for?

At 352 mm in length with a 320W TDP, this card is poorly suited to users working with compact or small-form-factor cases that have limited physical clearance or constrained airflow. Since air-water cooling integration is absent, users who have invested in custom liquid cooling loops will find no direct compatibility path. Additionally, those whose workflows or display setups depend on USB-C output connectivity will need to look elsewhere, as no such port is available on this model.
