Colorful iGame GeForce RTX 5070 Ultra W OC specifications and in-depth review

Colorful iGame GeForce RTX 5070 Ultra W OC

Manufacturer: Colorful

The Colorful iGame GeForce RTX 5070 Ultra W OC is a Blackwell-based graphics card designed for demanding workloads, offering a blend of modern rendering features and a substantial memory configuration. Built on a 5nm semiconductor process and housing 31,100 million transistors, it carries RGB lighting and fits within a 300.5 mm length and 120 mm height form factor. Its 250W TDP reflects the compute density packed into its design, and it connects via PCIe 5.0 for maximum host bandwidth.

On the memory side, the card ships with 12GB of GDDR7 across a 192-bit bus, delivering up to 672 GB/s of bandwidth at an effective speed of 28,000 MHz. The GPU runs at a base clock of 2,325 MHz, boosting to 2,557 MHz, and achieves 31.42 TFLOPS of floating-point performance alongside a texture rate of 490.9 GTexels/s. It supports DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and Intel Resizable BAR, with display output covered by one HDMI 2.1b port and three DisplayPort outputs, supporting up to four simultaneous displays.

Pros
  • Supports up to four simultaneous displays, offering flexibility for multi-monitor setups
  • ECC memory support adds a layer of data integrity for error-sensitive workloads
  • Intel Resizable BAR is included, allowing the CPU to access the full GPU framebuffer for smoother data transfers
  • RGB lighting is built in, providing visual customization without requiring additional hardware
  • HDMI 2.1b output ensures compatibility with modern high-refresh-rate and high-resolution displays
  • Double Precision Floating Point (DPFP) support broadens usability beyond standard rendering workloads
Cons
  • The 192-bit memory bus is narrower than what some cards in this segment offer, which limits potential bandwidth scaling
  • No USB-C output is available, restricting connectivity options for displays or devices that rely on that interface
  • Air-water cooling is not supported, limiting thermal management to the card's built-in air cooling solution
  • With a 250W TDP, the card places a notable power demand on the system, requiring a capable PSU and adequate case airflow
Who is this for?

This card is well-suited to users who work across demanding rendering and compute workloads, given its 31.42 TFLOPS of floating-point performance, DPFP support, and ECC memory, which together make it a reasonable fit for tasks requiring numerical accuracy and sustained GPU throughput. Gamers and creators who rely on ray tracing and DLSS will find those features natively supported, and anyone running a multi-monitor setup of up to four displays will benefit from the broad output configuration of three DisplayPort and one HDMI 2.1b port.

Who is this NOT for?

Users who need USB-C display connectivity will find this card lacking, as no such output is present, making it a poor match for setups that depend on that interface. Those working in environments where power efficiency is a priority may find the 250W TDP difficult to accommodate without a well-specified power supply and adequate airflow. Additionally, users seeking Intel XeSS (XMX) support will need to look elsewhere, as that feature is absent from this card's specification set.
