Colorful iGame GeForce RTX 4080 Super Ultra W OC

Manufacturer: Colorful

The Colorful iGame GeForce RTX 4080 Super Ultra W OC is a high-end graphics card based on NVIDIA's Ada Lovelace architecture, manufactured on a 5 nm process node and housing 45,900 million transistors. It ships with 16GB of GDDR6X memory across a 256-bit bus, offering a maximum bandwidth of 736 GB/s, and carries a thermal design power rating of 320W. RGB lighting is included, and the card measures 337 mm in length and 150 mm in height.

On the performance side, the card operates at a base clock of 2295 MHz and reaches a boost of 2595 MHz, delivering 53.15 TFLOPS of floating-point throughput alongside a texture rate of 830.4 GTexels/s and a pixel rate of 290.6 GPixels/s. Its 10,240 shading units are paired with 320 texture mapping units and 112 render output units. Feature support includes DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, Double Precision Floating Point, Intel Resizable BAR, and multi-display output across up to four screens via three DisplayPort 1.4 connectors and one HDMI 2.1 port.

Pros
  • Supports ray tracing and DLSS, enabling advanced rendering and upscaling features in compatible applications
  • 16GB of GDDR6X VRAM with 736 GB/s bandwidth accommodates memory-intensive workloads and high-resolution rendering
  • Four simultaneous display outputs allow for expansive multi-monitor setups
  • ECC memory support adds data integrity protection for compute-sensitive tasks
  • Double Precision Floating Point support extends usability to professional and scientific compute workloads
  • RGB lighting is built in, offering visual customization without requiring additional hardware
Cons
  • 320W TDP places significant demand on system power delivery and case airflow
  • At 337 mm in length, the card may not fit in smaller or mid-tower cases without careful planning
  • No USB-C or DVI outputs limits compatibility with certain monitors and display adapters
  • Air-water hybrid cooling is not supported, restricting cooling options to standard air or separate liquid solutions
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, given its 53.15 TFLOPS of floating-point performance, Double Precision Floating Point support, and ECC memory — a combination that serves both high-end gaming and professional GPU compute tasks. Content creators working with large textures or high-resolution assets will benefit from the 16GB of GDDR6X VRAM and 736 GB/s of memory bandwidth, while those using multi-monitor setups of up to four displays will find the output configuration directly accommodating.

Who is this NOT for?

Users working within compact or small-form-factor builds will likely find the card's 337 mm length a limiting factor, as fitting it requires a sufficiently spacious case. The 320W TDP also makes it a poor match for systems with modest power supplies or limited airflow, since it demands robust power delivery and thermal management. Additionally, users who rely on USB-C display outputs or DVI connections will find no support for either on this card, which could be a constraint depending on the monitor ecosystem in use.
