Colorful iGame GeForce RTX 4080 Super Loong Edition OC

Manufacturer: Colorful

The Colorful iGame GeForce RTX 4080 Super Loong Edition 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 features 54.07 TFLOPS of floating-point performance, making it a capable option for demanding rendering workloads, and comes equipped with RGB lighting along with support for up to four simultaneous displays.

On the memory side, the card carries 16GB of GDDR6X across a 256-bit bus, reaching an effective speed of 23,000 MHz and delivering up to 736 GB/s of bandwidth. Its 10,240 shading units are paired with 320 texture mapping units and 112 ROPs, with a base GPU clock of 2,295 MHz that boosts up to 2,640 MHz under load. The card has a TDP of 350W, connects via PCIe 4.0, and offers three DisplayPort outputs alongside one HDMI 2.1 port, with full support for DirectX 12 Ultimate, ray tracing, and DLSS.

Pros
  • Supports up to four simultaneous displays, offering flexibility for multi-monitor setups
  • Includes ray tracing and DLSS support, enabling more advanced rendering capabilities in compatible applications
  • ECC memory support adds a layer of data integrity for error-sensitive workloads
  • 16GB of GDDR6X across a 256-bit bus delivers substantial memory capacity and bandwidth for demanding tasks
  • RGB lighting is built in, allowing for visual customization within a system build
  • Intel Resizable BAR support enables the CPU to access the full GPU frame buffer, which can improve data throughput in supported configurations
Cons
  • A TDP of 350W places significant demands on the power supply, requiring a robust system build
  • The card measures 348.5 mm in length, which may not fit in smaller or mid-tower cases without careful planning
  • No USB-C, DVI, or mini DisplayPort outputs, limiting compatibility with certain older or specialized displays
  • Air-water cooling is not supported, restricting cooling options to the included air cooler only
Who is this for?

This card is well-suited to users running demanding 3D rendering, simulation, or compute workloads that benefit from high floating-point throughput and ECC memory support for data integrity. With 16GB of GDDR6X and a texture rate of 844.8 GTexels/s, it also fits users working in high-resolution content creation or game development pipelines where large memory capacity and fast data throughput matter. Additionally, the support for up to four displays and multi-display technology makes it a reasonable fit for multi-monitor professional environments requiring broad screen real estate.

Who is this NOT for?

The card's 350W TDP and 348.5 mm length make it a poor fit for users with compact or small-form-factor builds where physical space and power headroom are limited. The absence of USB-C and DVI outputs means it is not well-suited to users relying on older display hardware or USB-C monitor connections. It also lacks air-water cooling support, so users seeking custom liquid cooling configurations would need to look elsewhere, as only the included air cooling solution is supported.
