Floating-point throughput reaches 52.22 TFLOPS, and Double Precision Floating Point support is present alongside ECC memory compatibility. The card supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, and Intel Resizable BAR. Its port layout includes two HDMI 2.1a outputs and three DisplayPort connections, with no USB-C, DVI, or mini DisplayPort options. The card connects via PCIe 4.0, carries a 320W TDP, and measures 357.6 mm in width and 149.3 mm in height, with air-water cooling not supported.

Pros

16GB of GDDR6X VRAM on a 256-bit bus with 736.3 GB/s of bandwidth handles memory-intensive rendering and high-resolution texture workloads without running short on capacity
A turbo clock of 2,550 MHz across 10,240 shading units delivers 52.22 TFLOPS of floating-point throughput, making it capable for sustained compute-heavy tasks
Ray tracing and DLSS support are both present, enabling hardware-accelerated lighting effects and AI-based upscaling in compatible applications
Five display outputs — two HDMI 2.1a and three DisplayPort — offer flexible connectivity for multi-monitor configurations supporting up to four displays
ECC memory and Double Precision Floating Point support broaden the card's utility for users with compute or numerical precision requirements
RGB lighting is integrated into the card for users who want visual customization within their build

Cons

At 357.6 mm in length, the card requires careful fitment planning and may not seat properly in compact or mid-tower cases with limited clearance
The 320W TDP places substantial demands on the power supply and case ventilation, requiring a well-specified system to operate stably
Air-water cooling is not supported, so users seeking liquid cooling integration for thermal management will need to look elsewhere
No USB-C, DVI, or mini DisplayPort outputs are included, which limits compatibility with certain monitors or display adapters

Who is this for?

The Asus ROG Strix GeForce RTX 4080 Super is well-matched to users engaged in demanding rendering, ray-traced workloads, or GPU compute tasks, where the combination of 52.22 TFLOPS, 16GB of GDDR6X VRAM, and 736.3 GB/s of memory bandwidth provides the capacity to handle complex scenes and large data sets without hitting memory or throughput limits. The inclusion of DLSS and ray tracing support makes it a practical fit for users working in compatible real-time environments who want access to AI-based upscaling and hardware-accelerated lighting. It is equally suited to those running multi-monitor setups, given its five display outputs and support for up to four simultaneous displays, as well as users who benefit from ECC memory and Double Precision Floating Point support in compute-oriented applications.

Who is this NOT for?

Users building into compact or space-constrained cases will likely encounter fitment issues given the card's 357.6 mm length, and the 320W TDP demands a robust power supply and well-ventilated enclosure, making it a poor choice for thermally limited system configurations. Since air-water cooling is not supported, those who prefer or require liquid cooling integration for tighter thermal control will find no native provision for it here. The card is also not a practical fit for users relying on USB-C display outputs or legacy DVI connections, as neither interface is available in this port configuration.

Final Verdict

The Asus ROG Strix GeForce RTX 4080 Super is a thoroughly specified graphics card that pairs substantial compute throughput with 16GB of GDDR6X memory running at 736.3 GB/s of bandwidth, making it a capable choice for users whose workloads regularly push against VRAM and processing limits. Its support for ray tracing, DLSS, ECC memory, and Double Precision Floating Point rounds out a feature set that extends its relevance beyond pure rendering into compute-adjacent use cases. System requirements around power draw and physical dimensions do call for careful planning, and the absence of liquid cooling support and USB-C outputs will matter to some users. For those with compatible, well-specced builds, however, the ROG Strix GeForce RTX 4080 Super delivers a coherent and well-rounded package that holds up across a broad range of demanding workloads.
