Palit GeForce RTX 4080 Super Infinity 3

Manufacturer: Palit

The Palit GeForce RTX 4080 Super Infinity 3 is a desktop graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process and housing 45,900 million transistors. It features 10,240 shading units alongside 320 texture mapping units and 112 render output units, operating at a base clock of 2295 MHz with a turbo frequency of 2550 MHz. The card measures 294 mm in length and 116 mm in height, drawing up to 320W TDP and connecting to the host system via PCIe 4.0.

On the memory side, the card carries 16GB of GDDR6X across a 256-bit bus, delivering a maximum bandwidth of 736 GB/s at an effective speed of 23,000 MHz. It supports DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, and includes hardware-level ray tracing, DLSS, and Intel Resizable BAR. Display output is handled through one HDMI 2.1a port and three DisplayPort outputs, supporting up to four simultaneous displays. ECC memory and double-precision floating-point operations are both supported, while the card does not include USB-C outputs, DVI, or RGB lighting.

Pros
  • Supports up to four simultaneous displays through a combination of one HDMI 2.1a port and three DisplayPort outputs
  • 16GB of GDDR6X memory across a 256-bit bus delivers 736 GB/s of bandwidth, suitable for memory-intensive workloads
  • Hardware ray tracing and DLSS are both supported, enabling advanced rendering features in compatible applications
  • ECC memory support adds data integrity for compute-oriented tasks
  • Built on a 5 nm process with 45,900 million transistors, reflecting a dense and modern silicon design
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can improve frame delivery in supported systems
Cons
  • A 320W TDP demands a capable power supply and adequate case airflow, with no water-cooling option available
  • The card does not include any USB-C output, limiting compatibility with certain modern monitors and displays
  • No RGB lighting is present for users who prioritize visual customization in their build
  • At 294 mm in length, the card may not fit in smaller or compact chassis
  • XeSS (XMX) is not supported, restricting access to that particular upscaling technology
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, where the combination of 52.22 TFLOPS of floating-point performance, 16GB of GDDR6X memory, and ECC support provides both capacity and reliability. Content creators and 3D artists who work with large textures or complex scenes will benefit from the 736 GB/s memory bandwidth and high texture throughput. It also fits users who need multi-display setups, as the four video outputs — including an HDMI 2.1a and three DisplayPort connections — accommodate up to four monitors simultaneously, making it practical for professional workstation configurations.

Who is this NOT for?

Users working in compact or small-form-factor builds may find the 294 mm length and 320W TDP difficult to accommodate, as the card requires a spacious chassis and a robust power delivery setup without any water-cooling option available. Those who rely on USB-C display connectivity will find this card limiting, since no USB-C outputs are present. Additionally, users who prioritize aesthetic customization through RGB lighting will need to look elsewhere, as the card ships without any lighting features.

Final Verdict

The Palit GeForce RTX 4080 Super Infinity 3 is a capable graphics card built around NVIDIA's Ada Lovelace architecture, bringing together a dense transistor count, hardware ray tracing, DLSS support, and 16GB of GDDR6X memory with 736 GB/s of bandwidth into a package aimed at users with serious rendering or compute demands. Its multi-display output configuration and ECC memory support further extend its appeal toward workstation-oriented use cases. That said, its 320W power requirement, lack of water-cooling support, and 294 mm length mean it is best suited to well-equipped full-size builds rather than compact systems. For users whose environment accommodates its physical and power demands, this card offers a well-rounded specification set that covers both graphics and compute workloads without notable gaps in core feature support.
