Colorful iGame GeForce RTX 5070 Ti Ultra Z OC

Manufacturer: Colorful

The Colorful iGame GeForce RTX 5070 Ti Ultra Z OC is a high-specification graphics card based on NVIDIA's Blackwell architecture, manufactured on a 5nm process and housing 45,600 million transistors. It operates at a base clock of 2295 MHz with a boost frequency that reaches 2497 MHz, and RGB lighting is integrated into the card's design. With support for up to four simultaneous displays, it covers a broad range of multi-monitor configurations right out of the box.

On the memory side, the card carries 16GB of GDDR7 VRAM across a 256-bit bus, delivering a maximum bandwidth of 896 GB/s at an effective speed of 28,000 MHz, with ECC memory support also included. Compute throughput reaches 44.75 TFLOPS of floating-point performance alongside a texture rate of 699.2 GTexels/s, backed by 280 texture mapping units and 96 render output units. The card supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, and connects via one HDMI 2.1b port and three DisplayPort outputs. It carries a TDP of 300W and interfaces with the system over PCIe 5.0, with Intel Resizable BAR support enabled.

Pros
  • Supports up to four simultaneous displays, making it suitable for multi-monitor setups without additional hardware
  • ECC memory support adds a layer of data integrity useful for compute-intensive workloads
  • DLSS and ray tracing are both supported, enabling advanced rendering features in compatible applications
  • The 256-bit memory bus paired with 896 GB/s bandwidth allows for substantial data throughput in memory-intensive tasks
  • Intel Resizable BAR support is included, allowing the CPU to access the full GPU frame buffer for improved data transfer efficiency
  • RGB lighting is integrated into the card's design for users who prioritize visual customization in their build
Cons
  • A 300W TDP places significant demand on the system power supply, requiring careful planning around overall system power draw
  • No USB-C output is available, limiting direct connectivity options for displays or devices that rely on that interface
  • Air-water hybrid cooling is not supported, leaving users with only the standard thermal solution for heat management
  • At 300.5 mm in width, the card may not fit in smaller or compact PC cases without careful compatibility checks
Who is this for?

This card is well-suited to users who run demanding rendering and compute workloads, given its 44.75 TFLOPS of floating-point performance, 8960 shading units, and ECC memory support that helps maintain data integrity under sustained load. The combination of ray tracing, DLSS, and DirectX 12 Ultimate support makes it a strong fit for users engaged in modern, graphically intensive gaming where these features are actively leveraged. Those who regularly work across multi-monitor configurations will also find the four-display support and three DisplayPort outputs practical for wide desktop setups.

Who is this NOT for?

Users working within space-constrained or compact builds may find the card's 300.5 mm width a limiting factor, as many smaller form-factor cases will not accommodate it without compatibility issues. The 300W TDP makes this card a poor match for systems with modest power supplies or builds where overall power draw needs to be kept low. Additionally, users who rely on USB-C display output or require a DVI connection for older monitors will find the port selection unsuitable, as neither interface is present on this card.
