Colorful iGame GeForce RTX 5080 Ultra W OC VS Gigabyte GeForce RTX 5080 Gaming OC

Both cards share an identical foundation: the same 2295 MHz base clock, 10752 shading units, 336 TMUs, 112 ROPs, and 1875 MHz memory speed. This means any performance gap between them is entirely determined by how aggressively each manufacturer has tuned the boost behavior — not by any architectural difference.

That gap becomes clear at the boost clock. The Gigabyte Gaming OC reaches a 2730 MHz GPU turbo, compared to 2655 MHz on the Colorful iGame Ultra W OC — a 75 MHz advantage that cascades into every derived metric. The Gigabyte card posts a higher floating-point throughput of 58.71 TFLOPS versus 57.09 TFLOPS, a pixel rate of 305.8 GPixel/s versus 297.4 GPixel/s, and a texture rate of 917.3 GTexels/s versus 892.1 GTexels/s. In practice, these translate to marginally better sustained frame rates in GPU-bound workloads and slightly faster throughput in compute or rendering tasks — not a transformative difference, but a consistent one.

For this performance group, the Gigabyte GeForce RTX 5080 Gaming OC holds a clear, if modest, edge. Its higher boost clock makes it the faster card on paper across every throughput metric. The Colorful iGame closes much of the gap at the base level, but buyers prioritizing peak GPU performance should give the nod to the Gigabyte model.

The Colorful iGame GeForce RTX 5080 Ultra W OC and the Gigabyte GeForce RTX 5080 Gaming OC share identical memory specifications across the board. Both cards have an effective memory speed of 30000 MHz and a maximum memory bandwidth of 960 GB/s. They both come equipped with 16GB of VRAM, use the GDDR7 memory type, and have a 256-bit memory bus width.

Additionally, both models support Error-Correcting Code (ECC) memory, ensuring data integrity during processing. There are no differences in any of the listed memory specifications between the two products.

In conclusion, for memory-related specs, the Colorful and Gigabyte cards are exactly the same, offering an equal performance foundation in terms of memory speed, bandwidth, VRAM, and error correction.

The Colorful iGame GeForce RTX 5080 Ultra W OC and the Gigabyte GeForce RTX 5080 Gaming OC share many common features. Both cards support DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, ensuring compatibility with modern graphics and compute workloads. They also both support multi-display technology, ray tracing, and 3D, along with DLSS. Additionally, both cards lack XeSS (XMX) support and are equipped with Intel Resizable BAR technology, while neither has LHR (Lite Hash Rate) features.

One key difference is in the number of supported displays. The Colorful card supports up to 4 displays, while the Gigabyte card supports 5 displays. Additionally, both cards include RGB lighting, though there are no further distinctions in this area.

Overall, the two cards are very similar in terms of features, with the primary difference being the number of supported displays, where the Gigabyte card offers one more option than the Colorful model.

The Colorful iGame GeForce RTX 5080 Ultra W OC and the Gigabyte GeForce RTX 5080 Gaming OC are identical in their port configurations. Both cards feature 1 HDMI output with HDMI 2.1b support, 3 DisplayPort outputs, and no USB-C, DVI, or mini DisplayPort outputs. The HDMI and DisplayPort specifications are the same for both models, offering consistent connectivity options across the two products.

In summary, there are no differences in the ports or output types between the Colorful and Gigabyte cards. Both models provide the same display connectivity features, including HDMI 2.1b and DisplayPort 1.4.

The Colorful iGame GeForce RTX 5080 Ultra W OC and the Gigabyte GeForce RTX 5080 Gaming OC share several key specifications. Both cards utilize the Blackwell GPU architecture and feature a 5 nm semiconductor size. They also have the same number of transistors, with both cards containing 45,600 million transistors, and both support PCI Express (PCIe) version 5. Additionally, neither model includes air-water cooling.

There are differences in the Thermal Design Power (TDP) and physical dimensions. The Colorful card has a TDP of 380W, while the Gigabyte card is slightly lower at 360W. In terms of size, the Colorful card measures 331 mm in width and 139.3 mm in height, while the Gigabyte card is slightly wider at 340 mm and taller at 140 mm.

Overall, the two cards are very similar, with the main differences being the TDP and slightly different physical dimensions, with the Gigabyte card being marginally larger and having a lower power requirement.
