Asus TUF Gaming GeForce RTX 4080 Super

Manufacturer: Asus

The Asus TUF Gaming GeForce RTX 4080 Super is a high-end graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process with 45,900 million transistors. Asus equips this card with 16GB of GDDR6X memory across a 256-bit bus, delivering a maximum bandwidth of 736.3 GB/s alongside an effective memory speed of 23,000 MHz. The card supports up to four displays simultaneously and includes RGB lighting, making it a visually distinctive addition to a system build.

On the performance side, the Asus TUF Gaming GeForce RTX 4080 Super runs at a base GPU clock of 2,295 MHz, with a turbo frequency reaching 2,550 MHz, contributing to a floating-point throughput of 52.22 TFLOPS. Its 10,240 shading units are complemented by 320 texture mapping units and 112 render output units, yielding a texture rate of 816 GTexels/s and a pixel rate of 285.6 GPixels/s. The card carries a 320W TDP, connects via PCIe 4.0, and supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS. For display connectivity, it offers two HDMI 2.1a ports and three DisplayPort outputs, while Intel Resizable BAR support is also included.

Pros
  • 52.22 TFLOPS of floating-point performance and a 2,550 MHz turbo clock make this a capable card for demanding rendering workloads
  • 16GB of GDDR6X VRAM across a 256-bit bus with 736.3 GB/s of bandwidth supports memory-heavy tasks and high-resolution textures effectively
  • Ray tracing and DLSS are both supported, enabling hardware-accelerated lighting and AI-based upscaling in compatible applications
  • Five display outputs — two HDMI 2.1a and three DisplayPort — allow flexible multi-monitor setups supporting up to four simultaneous displays
  • ECC memory support adds a layer of data integrity for compute-oriented or professional workloads
  • RGB lighting is built into the card for users who want visual customization within their system
Cons
  • A 320W TDP places significant power demands on the system, requiring a capable power supply and adequate case airflow
  • Air-water cooling is not supported, limiting thermal management options to the card's built-in air cooler
  • The 348.2 mm card length may create fitment challenges in smaller or mid-tower cases
  • There are no USB-C, DVI, or mini DisplayPort outputs, which may limit compatibility with certain older or specialized display hardware
  • XeSS (XMX) is not supported, restricting upscaling options to DLSS only
Who is this for?

This card is well-suited to users running high-resolution rendering and ray-traced workloads, where its 52.22 TFLOPS of floating-point throughput, 16GB of GDDR6X VRAM, and 736.3 GB/s of memory bandwidth provide meaningful headroom. The inclusion of DLSS support makes it a practical fit for those working in compatible real-time environments who want to leverage AI-based upscaling. It is also a reasonable choice for users with multi-monitor setups, given the five available display outputs and support for up to four simultaneous displays, as well as for those with compute-adjacent needs who benefit from ECC memory and Double Precision Floating Point support.

Who is this NOT for?

Users working within compact or small-form-factor builds may find the 348.2 mm card length difficult to accommodate, and the 320W TDP demands a well-ventilated case with a robust power supply, making this a poor fit for thermally constrained environments. Since air-water cooling is not supported, those requiring advanced thermal management solutions beyond a standard air cooler will find their options limited. The card is also not well-matched to users who depend on USB-C display outputs or legacy DVI connectivity, as neither interface is present in this configuration.
