Colorful iGame GeForce RTX 4070 Ti Super Loong Edition OC

Manufacturer: Colorful

The Colorful iGame GeForce RTX 4070 Ti Super Loong Edition OC is a graphics card based on NVIDIA's Ada Lovelace architecture, fabricated on a 5 nm process with 45,900 million transistors. It carries 16GB of GDDR6X VRAM across a 256-bit memory bus, delivering up to 672 GB/s of bandwidth at an effective speed of 21,000 MHz. The card supports ray tracing, DLSS, DirectX 12 Ultimate, and can output to up to four displays through three DisplayPort and one HDMI 2.1 connection. RGB lighting is also included.

On the performance side, the GPU runs at a base clock of 2,340 MHz with a turbo frequency of 2,685 MHz, producing 45.37 TFLOPS of floating-point throughput alongside a texture rate of 708.8 GTexels/s and a pixel rate of 257.8 GPixel/s. Its 8,448 shading units work in tandem with 264 texture mapping units and 96 render output units. The card has a rated TDP of 310W, connects via PCIe 4.0, supports ECC memory and Intel Resizable BAR, and measures 336.9 mm in width by 144.5 mm in height. Cooling is handled by air only, as water cooling is not supported.

Pros
  • 16GB of GDDR6X VRAM across a 256-bit bus delivers 672 GB/s of memory bandwidth, giving the card substantial headroom for texture-heavy and high-resolution workloads
  • 45.37 TFLOPS of floating-point performance supported by 8,448 shading units provides substantial compute throughput for demanding rendering tasks
  • Ray tracing and DLSS are both supported, enabling hardware-accelerated lighting and upscaling in compatible applications
  • RGB lighting is included, making the card suitable for builds where interior aesthetics are a consideration
  • ECC memory support adds a layer of data integrity useful for compute or professional workloads
  • Intel Resizable BAR is supported, allowing the processor broader simultaneous access to GPU memory for improved data transfer efficiency
Cons
  • A 310W TDP places notable demands on system power delivery and case airflow, requiring careful build planning
  • Water cooling is not supported, limiting thermal management to air-only solutions which may be a constraint in thermally restricted environments
  • No USB-C, DVI, or mini DisplayPort outputs are available, which may limit compatibility with certain display setups
  • At 336.9 mm in length, the card requires a case with sufficient GPU clearance, ruling out many compact form factors
Who is this for?

This card is well-suited for users engaged in demanding rendering, high-resolution gaming, or GPU-accelerated compute tasks, where its 45.37 TFLOPS of floating-point performance and 672 GB/s of memory bandwidth can be fully utilized. The 16GB GDDR6X frame buffer across a 256-bit bus provides ample capacity for texture-heavy workloads and large datasets. Support for ray tracing, DLSS, ECC memory, and Intel Resizable BAR further broadens its appeal to users who need both visual fidelity and computational reliability, while the inclusion of RGB lighting and multi-display support for up to four screens makes it a practical fit for desktop setups that prioritize both functionality and aesthetics.

Who is this NOT for?

Users building in compact or small-form-factor cases may find this card difficult to accommodate given its 336.9 mm length, and those in thermally constrained environments will need to plan carefully around its 310W TDP with air-only cooling. The absence of water-cooling support removes a common option for users seeking quieter or more aggressive thermal management. Additionally, anyone relying on USB-C, DVI, or mini DisplayPort connectivity will find no compatible outputs on this card, making it a poor match for display setups that depend on those interfaces.
