Palit GeForce RTX 4080 Super Infinity 3 OC

Manufacturer: Palit

The Palit GeForce RTX 4080 Super Infinity 3 OC is a high-end graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process with 45,900 million transistors. It ships with 16GB of GDDR6X video memory across a 256-bit bus, delivering a maximum memory bandwidth of 736 GB/s at an effective memory speed of 23,000 MHz, making it well-suited for demanding rendering workloads.

The card operates at a base GPU clock of 2,295 MHz with a turbo frequency reaching 2,580 MHz, and its 10,240 shading units contribute to a floating-point throughput of 52.84 TFLOPS. A texture rate of 825.6 GTexels/s is supported by 320 texture mapping units and 112 render output units. For display connectivity, it provides one HDMI 2.1a port alongside three DisplayPort outputs, supporting up to four displays simultaneously. The card carries a TDP of 320W, measures 294 mm × 116 mm, and supports DirectX 12 Ultimate, OpenGL 4.6, ray tracing, and DLSS, while also featuring Intel Resizable BAR support.

Pros
  • Supports up to four displays simultaneously through three DisplayPort outputs and one HDMI 2.1a port, offering flexible multi-monitor setups
  • 16GB of GDDR6X memory across a 256-bit bus provides substantial VRAM capacity for memory-intensive workloads
  • ECC memory support helps maintain data integrity during compute-heavy tasks
  • Ray tracing and DLSS are both supported, enabling advanced rendering and upscaling capabilities
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can improve frame delivery
  • Double Precision Floating Point (DPFP) support extends the card's suitability beyond graphics into compute applications
Cons
  • A 320W TDP places notable demands on system power delivery and case airflow
  • Water cooling is not supported, leaving thermal management entirely dependent on the air cooling solution
  • No USB-C output is available, limiting connectivity options for certain monitors and devices
  • DVI and mini DisplayPort outputs are absent, which may require adapters for users with older display equipment
  • No RGB lighting is present for users who prioritize visual customization within their build
Who is this for?

This card is well-matched for users running demanding rendering and compute workloads, thanks to its 52.84 TFLOPS of floating-point throughput, DPFP support, and ECC memory — attributes that matter in 3D content creation, simulation, and GPU-accelerated compute tasks. The 16GB GDDR6X frame buffer and 736 GB/s memory bandwidth also make it a strong fit for high-resolution gaming and real-time ray tracing, where large texture assets and fast memory throughput are essential. Users who need multi-monitor productivity setups will benefit from the four simultaneous display outputs across HDMI 2.1a and three DisplayPort connections.

Who is this NOT for?

With a 320W TDP and no water cooling support, this card is not well-suited for compact or small-form-factor builds where thermal headroom and power delivery are constrained. Users who rely on USB-C or DVI display connections will find the port selection limiting, as neither interface is available on this model. Additionally, those looking for visual customization through RGB lighting will need to look elsewhere, as this card offers no such feature.
