Asus TUF Gaming GeForce RTX 4080 Super OC Edition

Manufacturer: Asus

The Asus TUF Gaming GeForce RTX 4080 Super OC Edition is a high-end graphics card designed for demanding workloads and gaming, running on NVIDIA's Ada Lovelace architecture built on a 5 nm manufacturing process. The card ships with a boost clock of 2610 MHz in its OC configuration, alongside support for ray tracing, DLSS, and DirectX 12 Ultimate, making it a feature-complete option within the RTX 40 series lineup. RGB lighting and support for up to four simultaneous displays round out the user-facing feature set.

On the memory side, the card is equipped with 16GB of GDDR6X running across a 256-bit bus at an effective speed of 23,000 MHz, delivering a maximum bandwidth of 736.3 GB/s. The GPU itself counts 10,240 shading units, 320 texture mapping units, and 112 render output units, translating into a texture rate of 835.2 GTexels/s and a pixel rate of 292.3 GPixel/s. With a rated TDP of 320W and physical dimensions of 348.2 mm in length and 150 mm in height, the card relies on air cooling and connects via PCIe 4.0. Display output options include two HDMI 2.1a ports and three DisplayPort outputs, with Intel Resizable BAR support also included.

Pros
  • Supports up to four displays simultaneously, with five physical output ports covering two HDMI 2.1a and three DisplayPort connections
  • 16GB of GDDR6X memory running across a 256-bit bus provides substantial VRAM for memory-intensive workloads
  • ECC memory support adds data integrity protection useful for compute and professional tasks
  • DLSS and ray tracing support are both present, expanding the card's rendering capabilities
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, improving data transfer efficiency
  • RGB lighting is included for users who want visual customization in their build
Cons
  • A 320W TDP places significant demands on system power delivery and case airflow
  • The card measures 348.2 mm in length, which may not fit in smaller or compact PC cases
  • No USB-C output is available, limiting connectivity options for monitors or devices that rely on that interface
  • Air-water cooling is not supported, restricting thermal management to air cooling only
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads that benefit from 16GB of GDDR6X memory, wide memory bandwidth, and ECC support — including 3D artists, simulation workflows, and content creators working with large assets. Gamers who want to drive multi-monitor setups will appreciate the five physical output ports supporting up to four displays, along with ray tracing and DLSS support for visually intensive titles. The Ada Lovelace architecture and Double Precision Floating Point capability also make it a reasonable fit for users with mixed gaming and compute needs in the same system.

Who is this NOT for?

Users building in compact or small-form-factor cases will likely find the 348.2 mm card length a hard constraint, as many ITX and mATX enclosures cannot accommodate a board of that size. The 320W TDP also makes this card a poor match for systems with modest power supplies or limited case airflow, since inadequate cooling will prevent stable operation. Additionally, users who rely on USB-C display output — such as those connecting to certain ultrawide monitors or portable displays — will find no support for that interface, as no USB-C ports are present on this model.

Final Verdict

The Asus TUF Gaming GeForce RTX 4080 Super OC Edition is a well-specified graphics card that brings together a robust feature set — including ray tracing, DLSS, ECC memory support, and a five-port display output configuration — within the Ada Lovelace architecture. Its 16GB of GDDR6X memory paired with 736.3 GB/s of bandwidth gives it genuine headroom for memory-intensive tasks alongside gaming, and the inclusion of Double Precision Floating Point support extends its relevance beyond pure rasterization workloads. That said, its 320W TDP and 348.2 mm length mean system compatibility needs careful consideration before purchase. For users with a well-ventilated full-size build and workloads that can take advantage of its full feature set, this card represents a thorough and capable option within the RTX 40 series.
