Colorful iGame GeForce RTX 4070 Super Ultra W OC

Manufacturer: Colorful

The Colorful iGame GeForce RTX 4070 Super Ultra W OC is a graphics card built on NVIDIA's Ada Lovelace architecture, fabricated on a 5 nm process with 35,800 million transistors. It features 7168 shading units and a boost clock of 2565 MHz, translating to 36.77 TFLOPS of floating-point performance and a texture rate of 574.6 GTexels/s, giving it a well-defined specification profile within the RTX 4070 Super lineup.

The card carries 12GB of GDDR6X VRAM at an effective speed of 21,000 MHz across a 192-bit bus, yielding up to 504 GB/s of memory bandwidth. ECC memory support is included alongside DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, and Intel Resizable BAR. Output options consist of one HDMI 2.1 port and three DisplayPort outputs, supporting up to four simultaneous displays. The card has a TDP of 220W, measures 324.9 mm in length and 134 mm in height, and connects via PCIe 4.

Pros
  • The 2565 MHz boost clock delivers a notably elevated operating frequency for this GPU class, translating into 36.77 TFLOPS of floating-point throughput
  • Ray tracing and DLSS are both supported at the hardware level, enabling real-time lighting effects and AI-driven upscaling in compatible applications
  • 12GB of GDDR6X VRAM operating at 21,000 MHz effective speed provides substantial frame buffer capacity and memory throughput of 504 GB/s
  • ECC memory support is included, adding a layer of data integrity useful for compute-sensitive workloads beyond standard gaming
  • DPFP support broadens the card's applicability to double-precision compute tasks, expanding its usefulness beyond purely graphical workloads
  • Four simultaneous display outputs — one HDMI 2.1 and three DisplayPort — offer flexible multi-monitor configurations
Cons
  • At 324.9 mm in length and 134 mm in height, the card has a substantial physical footprint that may not fit in compact or mid-tower cases without careful clearance planning
  • The 192-bit memory bus width places a ceiling on potential bandwidth scaling relative to wider bus implementations
  • No USB-C video output is available, limiting compatibility with displays or devices that rely on that connection type
  • Multi-GPU is not supported, restricting the system to a single-card configuration
  • Air-water hybrid cooling is absent, leaving thermal management entirely dependent on the air cooling solution
  • RGB lighting is not included, which may be a drawback for users who factor visual build aesthetics into their setup
Who is this for?

This card is a good fit for users who prioritize ray tracing and DLSS in their gaming or creative workloads, as both are supported at the hardware level alongside DirectX 12 Ultimate. The 12GB of GDDR6X VRAM with 504 GB/s of bandwidth makes it well-suited to texture-heavy rendering and content creation tasks that place sustained demand on frame buffer capacity. Users who also engage in double-precision compute workloads will benefit from DPFP and ECC memory support, which together extend the card's utility beyond conventional graphics use. Those needing a broad multi-monitor setup will also find the four simultaneous display outputs practical.

Who is this NOT for?

The card's dimensions of 324.9 mm in length and 134 mm in height make it a poor match for compact or small form-factor builds where physical clearance is restricted. Users who rely on USB-C video output for their display setup will find no such port available, limiting compatibility with certain modern monitors and portable displays. Additionally, those looking to scale performance across multiple cards will be constrained, as multi-GPU configurations are not supported, locking the system to a single-card setup.

Final Verdict

The Colorful iGame GeForce RTX 4070 Super Ultra W OC brings together a well-defined set of specifications centered on its 2565 MHz boost clock and 12GB of GDDR6X VRAM, supported by ray tracing, DLSS, DPFP, and ECC memory — a combination that covers both gaming and compute use cases with reasonable breadth. Its four-display output capability and Intel Resizable BAR support add further practical value for users with demanding workspace or gaming configurations. That said, its considerable physical dimensions and the absence of USB-C video output and multi-GPU support mean it works best in full-size builds with a specific connectivity setup in mind. For users whose system accommodates its footprint and whose workflow aligns with its feature set, this card represents a coherent and capable option within the RTX 4070 Super segment.
