SKU: 5625

Manufacturer: Nvidia

The Nvidia GeForce RTX 4080 Super is a high-end graphics card based on the Ada Lovelace architecture, manufactured on a 5 nm process with 45,900 million transistors. It operates at a base clock of 2290 MHz, boosting up to 2550 MHz under load, and supports a broad feature set including ray tracing, DLSS, and DirectX 12 Ultimate. The card accommodates up to four displays simultaneously and measures 304 mm in length and 137 mm in height.

On the memory side, the RTX 4080 Super is equipped with 16GB of GDDR6X running across a 256-bit bus at an effective speed of 23,000 MHz, delivering up to 736.3 GB/s of bandwidth. Its 10,240 shading units are paired with 320 texture mapping units and 112 render output units, producing a texture rate of 816 GTexels/s and a pixel rate of 285.6 GPixel/s. The card carries a TDP of 320W, connects via PCIe 4.0, and includes one HDMI 2.1 port alongside three DisplayPort outputs, with Intel Resizable BAR support and ECC memory compatibility also present.

Pros

Supports up to four simultaneous displays, offering flexible multi-monitor setups
16GB of GDDR6X VRAM across a 256-bit bus delivers substantial memory capacity and bandwidth for demanding workloads
Ray tracing and DLSS are both supported, expanding rendering and upscaling capabilities
ECC memory support adds a layer of data integrity for compute-sensitive tasks
Built on a 5 nm process with 45,900 million transistors, reflecting a high transistor density for its die size
Includes three DisplayPort outputs and one HDMI 2.1 port, covering a range of modern display connectivity needs

Cons

320W TDP places significant power demands on the system, requiring a capable power supply
No USB-C video output is available
No DVI or mini DisplayPort options for users with older or specialized displays
Does not include air-water cooling, leaving thermal management entirely dependent on the card's own air-cooling solution
Physical dimensions of 304 mm in length may pose fitment challenges in compact or mid-tower cases

Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, given its 52.22 TFLOPS of floating-point performance, DPFP support, and ECC memory capability, which together make it a reliable choice for GPU-accelerated tasks requiring numerical precision. Content creators and developers working with large assets will benefit from the 16GB of GDDR6X VRAM and 736.3 GB/s of memory bandwidth, while those building multi-screen setups will appreciate native support for up to four simultaneous displays via a combination of DisplayPort and HDMI 2.1 outputs. Ray tracing and DLSS support also make it a solid fit for users engaged in real-time 3D work or visually intensive applications.

Who is this NOT for?

Users working in space-constrained builds may find the 304 mm card length a limiting factor, as it can be incompatible with smaller form-factor or compact mid-tower cases. The 320W TDP makes this card a poor match for systems with modest power supplies or limited airflow, since it demands a well-specced thermal and electrical setup to operate stably. Additionally, users who require USB-C video output, DVI connectivity, or hardware-level RGB lighting controls will find none of those options available here.
