Asus ROG Strix GeForce RTX 4080 Super White OC Edition

Manufacturer: Asus

The Asus ROG Strix GeForce RTX 4080 Super White OC Edition is a high-tier graphics card from Asus's ROG Strix lineup, built on NVIDIA's Ada Lovelace architecture and fabricated on a 5 nm process with 45,900 million transistors. It measures 357.6 mm in length and 149.3 mm in height, placing it firmly in the larger end of the consumer graphics card spectrum. The card features RGB lighting and supports up to four simultaneous displays, with a 320W Thermal Design Power (TDP) that reflects the demands of its specification tier.

The card is equipped with 16GB of GDDR6X VRAM across a 256-bit memory bus, with an effective memory speed of 23,000 MHz and a maximum bandwidth of 736.3 GB/s. Its 10,240 shading units, 320 texture mapping units, and 112 render output units deliver a texture rate of 844.8 GTexels/s and a floating-point performance of 54.07 TFLOPS, with a boost clock reaching 2,640 MHz. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3.0, ray tracing, DLSS, stereoscopic 3D, ECC memory, and Intel Resizable BAR. Port connectivity consists of three DisplayPort outputs and two HDMI 2.1a ports, with no USB-C, DVI, or mini DisplayPort outputs available.

Pros
  • 16GB of GDDR6X VRAM across a 256-bit bus delivers a maximum bandwidth of 736.3 GB/s, supporting memory-intensive graphical and compute workloads
  • A boost clock of 2,640 MHz combined with 54.07 TFLOPS of floating-point performance reflects a high computational throughput for its class
  • Five total display outputs — three DisplayPort and two HDMI 2.1a — provide flexible multi-monitor configuration options
  • ECC memory support adds data integrity protection, making the card usable in workloads where memory error tolerance is important
  • Ray tracing, DLSS, and DirectX 12 Ultimate support are all present, covering the full range of modern rendering feature requirements
  • Intel Resizable BAR support allows the CPU to access the entire GPU frame buffer simultaneously, which can improve data transfer efficiency
Cons
  • At 357.6 mm in length and 149.3 mm in height, the card has a large physical footprint that may not fit in compact or mid-tower cases without careful planning
  • The 320W TDP places considerable demands on system power delivery, requiring a suitably rated power supply
  • Air-water cooling is not supported, meaning users who prefer liquid cooling configurations cannot use this card in such setups
  • No USB-C output is available, limiting direct compatibility with displays or adapters that rely on that connection type
  • XeSS (XMX) is not supported, restricting access to that particular upscaling technology
Who is this for?

This card is well-suited to users engaged in high-resolution gaming or GPU-accelerated compute workloads, where its 54.07 TFLOPS of floating-point performance, 16GB of GDDR6X VRAM, and 736.3 GB/s of memory bandwidth can be fully utilized. The inclusion of ray tracing, DLSS, DirectX 12 Ultimate, and ECC memory support also makes it a practical fit for those working across both creative and rendering pipelines that demand both visual fidelity and data reliability. Users who require multi-monitor setups with up to four displays will find the five-port output configuration — three DisplayPort and two HDMI 2.1a — particularly accommodating.

Who is this NOT for?

The card's 357.6 mm length and 149.3 mm height make it a poor fit for compact or small-form-factor builds where physical space is a hard constraint. Its 320W TDP also rules it out for systems with limited power supply headroom, as the demands on overall system power delivery are substantial. Additionally, users who depend on USB-C display connectivity or prefer liquid cooling configurations will find this card lacking, as neither USB-C outputs nor air-water cooling support are available.

Final Verdict

The Asus ROG Strix GeForce RTX 4080 Super White OC Edition is a specification-dense graphics card that brings together a 2,640 MHz boost clock, 54.07 TFLOPS of floating-point performance, and 16GB of GDDR6X VRAM with 736.3 GB/s of memory bandwidth in a single package. Its support for ray tracing, DLSS, DirectX 12 Ultimate, ECC memory, and a five-port display output configuration makes it a capable fit for users with demanding graphical or compute-oriented workloads. The trade-offs — a 320W TDP, a large physical footprint, and the absence of USB-C outputs or liquid cooling support — mean it suits well-provisioned full-size builds far better than compact or power-constrained systems. For users whose setup can accommodate its requirements, the ROG Strix GeForce RTX 4080 Super White OC Edition represents a thoroughly specified option within the high-end graphics card segment.
