Gainward GeForce RTX 4080 Super Panther OC

Manufacturer: Gainward

The Gainward GeForce RTX 4080 Super Panther OC is a graphics card built on Nvidia's Ada Lovelace architecture, fabricated on a 5 nm process with 45,900 million transistors. It runs at a factory-overclocked base clock of 2295 MHz, reaching 2580 MHz in turbo mode, and comes equipped with RGB lighting, ray tracing, DLSS, and DirectX 12 Ultimate support. The card can drive up to four displays simultaneously and measures 328.9 mm in length and 128 mm in height.

On the memory side, the Panther OC carries 16GB of GDDR6X VRAM across a 256-bit bus at an effective speed of 23,000 MHz, resulting in a maximum bandwidth of 736.3 GB/s. Its 10,240 shading units are backed by 320 texture mapping units and 112 render output units, translating to a texture rate of 825.6 GTexels/s and a pixel rate of 289 GPixel/s. Floating-point performance is rated at 52.84 TFLOPS, and the card also supports ECC memory and Double Precision Floating Point (DPFP) for compute workloads requiring numerical reliability. Connectivity is provided by three DisplayPort outputs and one HDMI 2.1a port, with Intel Resizable BAR support included and a TDP of 320W over PCIe 4.0.

Pros
  • 16GB of GDDR6X VRAM across a 256-bit bus provides substantial memory capacity for demanding rendering and compute tasks
  • ECC memory support adds data integrity protection for compute-sensitive workloads
  • RGB lighting is built into the card, allowing for visual customization within the system
  • Ray tracing and DLSS are both supported, extending the card's usefulness across real-time 3D and upscaling scenarios
  • Supports up to four simultaneous displays via three DisplayPort and one HDMI 2.1a output
  • DPFP support broadens its suitability for workloads requiring double precision numerical computation
Cons
  • A TDP of 320W places significant power demands on the system, requiring a capable power supply and adequate airflow
  • At 328.9 mm in length, the card may not fit in smaller or compact cases without careful planning
  • No air-water cooling option is available, leaving thermal performance entirely dependent on air cooling
  • No USB-C video output is included, limiting compatibility with monitors that require that connection type
  • XeSS (XMX) is not supported, restricting upscaling options to DLSS only
Who is this for?

The Gainward GeForce RTX 4080 Super Panther OC is well-suited to users running compute-intensive and rendering workloads that benefit from 52.84 TFLOPS of floating-point performance, DPFP support, and ECC memory capability. Content creators and developers working with large datasets or high-resolution assets will find the 16GB of GDDR6X VRAM and 736.3 GB/s of memory bandwidth a practical fit, while those building multi-monitor setups can take advantage of the four available display outputs. The inclusion of ray tracing, DLSS, and DirectX 12 Ultimate also makes it a capable card for visually demanding real-time 3D applications.

Who is this NOT for?

At 328.9 mm in length, this card is not a good match for users working with compact or small form-factor cases, where physical fitment may be a genuine obstacle. The 320W TDP also makes it unsuitable for systems with limited power delivery capacity or restricted airflow, as the card relies entirely on air cooling with no air-water option available. Users who require USB-C video output or XeSS upscaling support will also find those capabilities absent here.

Final Verdict

The Gainward GeForce RTX 4080 Super Panther OC is a thoroughly specified graphics card that pairs a dense feature set with the raw throughput to back it up. Its 16GB of GDDR6X memory, DPFP support, and ECC capability give it genuine reach across both visual and compute-oriented workloads, while ray tracing, DLSS, and four-display output round out a well-equipped package for demanding users. The 320W TDP and 328.9 mm length do impose real constraints on system compatibility, so it rewards careful build planning — but for users whose setup can accommodate it, the Panther OC delivers a complete and capable card that holds its ground across a broad range of serious use cases.
