Colorful iGame GeForce RTX 4070 Ti Super Vulcan OC

Manufacturer: Colorful

The Colorful iGame GeForce RTX 4070 Ti Super Vulcan OC is a graphics card based on NVIDIA's Ada Lovelace architecture, fabricated on a 5 nm process and packed with 45,900 million transistors. It ships with 16GB of GDDR6X VRAM across a 256-bit memory bus, and its feature set includes ray tracing, DLSS, stereoscopic 3D support, and compatibility with Intel Resizable BAR.

The card operates at a base clock of 2,340 MHz with a boost up to 2,685 MHz, backed by 8,448 shading units, 264 texture mapping units, and 96 render output units, producing a texture rate of 708.8 GTexels/s and a pixel rate of 257.8 GPixel/s. Memory bandwidth reaches 672 GB/s at an effective speed of 21,000 MHz, and ECC memory support is included. Output connectivity consists of one HDMI 2.1 port and three DisplayPort outputs, supporting up to four displays, while the card draws up to 310W TDP and measures 348.5 mm × 159.5 mm.

Pros
  • 45.37 TFLOPS of floating-point performance places this card among the more compute-capable options in its class
  • 16GB of GDDR6X VRAM on a 256-bit bus delivers 672 GB/s of memory bandwidth, supporting memory-intensive workloads effectively
  • Ray tracing and DLSS are both supported, enabling advanced rendering and upscaling for compatible applications
  • ECC memory support adds a layer of data reliability for precision-sensitive compute tasks
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, improving data transfer efficiency in compatible systems
  • Four simultaneous display outputs are supported through a combination of one HDMI 2.1 port and three DisplayPort connections
Cons
  • A TDP of 310W places significant demands on the system power supply and case airflow
  • At 348.5 mm in length and 159.5 mm in height, the card requires a spacious case with adequate clearance
  • No RGB lighting is present, which may matter to users who prioritize visual customization in their builds
  • No USB-C output is available, limiting direct compatibility with certain modern monitors and docking solutions
  • Air-water hybrid cooling is not included, leaving all thermal management to the air-cooling solution alone
Who is this for?

This card is a strong fit for users running demanding rendering, compute, or graphics workloads that can take full advantage of 45.37 TFLOPS of floating-point performance and 672 GB/s of memory bandwidth. The 16GB GDDR6X VRAM with ECC support makes it well-suited for workloads requiring both capacity and data integrity, such as technical compute or content creation tasks. Users operating multi-display setups of up to four screens will also find the port configuration practical, and Intel Resizable BAR support ensures efficient data transfer in compatible PCIe 4 systems.

Who is this NOT for?

The card's 310W TDP makes it a poor match for systems with limited power delivery or constrained airflow, as it places considerable demands on both the power supply and the chassis cooling. At 348.5 mm in length, it is also unsuitable for compact or small-form-factor builds where physical clearance is restricted. Users who require USB-C display connectivity or expect built-in RGB lighting for aesthetic customization will find neither feature available on this model.
