Colorful iGame GeForce RTX 4070 Super Loong Edition OC

Manufacturer: Colorful

The Colorful iGame GeForce RTX 4070 Super Loong Edition OC is a graphics card grounded in NVIDIA's Ada Lovelace architecture, produced on a 5 nm node with 35,800 million transistors. It operates at a base clock of 1980 MHz with a boost clock of 2670 MHz, generating 38.28 TFLOPS of floating-point performance alongside a pixel rate of 213.6 GPixel/s and a texture rate of 598.1 GTexels/s. The card does not feature RGB lighting, and supports up to four simultaneous display outputs.

Memory comes in the form of 12GB of GDDR6X on a 192-bit bus running at an effective 21,000 MHz, with a maximum bandwidth of 504 GB/s and ECC memory support included. The feature set covers DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, stereoscopic 3D, and Intel Resizable BAR, while XeSS is not supported. Display outputs consist of one HDMI 2.1 port and three DisplayPort connections, with no USB-C, DVI, or mini DisplayPort options available. The card has a TDP of 245W, uses PCIe 4.0, relies on air cooling only, and measures 336.9 mm in width by 144.5 mm in height.

Pros
  • A boost clock of 2670 MHz combined with 38.28 TFLOPS of floating-point throughput provides solid compute capacity for rendering and GPU-intensive tasks
  • Ray tracing and DLSS support together enable compatibility with modern rendering techniques and upscaling workflows
  • DirectX 12 Ultimate and OpenCL 3 support cover a wide range of current graphics and compute application requirements
  • ECC memory support adds a useful degree of data integrity for workloads where memory accuracy is important
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can benefit frame pacing in compatible systems
  • Four simultaneous display outputs via three DisplayPort and one HDMI 2.1 port offer flexible multi-monitor configurations
Cons
  • At 336.9 mm in length and 144.5 mm in height, the card has a notably large physical footprint that demands careful verification of chassis clearance before installation
  • The 192-bit memory bus limits maximum bandwidth to 504 GB/s, which may constrain sustained throughput in heavily memory-bound workloads
  • No RGB lighting is present, which may be a drawback for users who prioritize visual customization in their builds
  • Water cooling is not supported, restricting thermal management options to air cooling only
  • XeSS upscaling is not available, limiting compatibility for users whose workflows or games depend on that technology
Who is this for?

This card is a natural fit for users focused on ray-traced rendering and DLSS-enabled workloads, where its 38.28 TFLOPS of floating-point throughput and 2670 MHz boost clock can be put to consistent use. The support for DirectX 12 Ultimate, OpenCL 3, and Intel Resizable BAR makes it well-suited to a range of modern graphics and compute applications, and those running multi-monitor setups of up to four displays will find the output configuration straightforward to use. Users who do not require RGB lighting and are comfortable working within a 245W power budget will find this card a capable and feature-complete option for sustained workloads.

Who is this NOT for?

At 336.9 mm in length, this card demands generous chassis clearance, making it a poor match for compact or mid-tower builds where physical space is limited. Users who depend on XeSS upscaling or require water cooling integration will find neither feature available here, which narrows the card's appeal for those specific use cases. Additionally, workloads that are highly sensitive to memory bandwidth may encounter constraints from the 192-bit bus and 504 GB/s bandwidth ceiling, particularly under sustained GPU-memory-intensive conditions.
