Asus ROG Astral GeForce RTX 5080 OC Edition VS Colorful iGame GeForce RTX 5070 Advanced OC

The most telling gap between these two cards lies in their raw computational muscle. The Asus ROG Astral RTX 5080 OC delivers 59.35 TFLOPS of floating-point performance versus 31.6 TFLOPS on the Colorful iGame RTX 5070 Advanced OC — nearly double the throughput. This difference flows directly from the shading unit count: 10,752 vs 6,144. In practice, this means the RTX 5080 can push far more parallel compute workloads simultaneously, which matters not just for gaming frame rates but also for AI-accelerated rendering, ray tracing workloads, and creative applications.

The clock speed story is more nuanced. The RTX 5070 actually has a marginally higher base clock (2325 MHz vs 2295 MHz), but the RTX 5080 pulls decisively ahead under boost, reaching 2760 MHz vs 2572 MHz. That wider boost headroom translates to more sustained peak performance during demanding scenes rather than just brief spikes. The texture and pixel throughput numbers reinforce this: the RTX 5080's 927.4 GTexels/s texture rate and 309.1 GPixel/s pixel rate are roughly 88% and 50% higher respectively, meaning noticeably sharper and faster geometry and texture processing at high resolutions. Memory speed also favors the RTX 5080 at 1875 MHz vs 1750 MHz, providing extra bandwidth headroom.

Both cards support Double Precision Floating Point (DPFP), which is relevant for compute and scientific workloads beyond gaming. Overall, the Asus ROG Astral RTX 5080 OC holds a clear and substantial performance advantage across every meaningful metric in this group — the RTX 5070 is not a slow card, but the 5080 occupies a categorically higher performance tier.

The Asus ROG Astral GeForce RTX 5080 OC Edition features an effective memory speed of 30000 MHz, which is faster than the Colorful iGame GeForce RTX 5070 Advanced OC’s 28000 MHz. In terms of maximum memory bandwidth, the RTX 5080 OC has a significant lead with 960 GB/s, while the RTX 5070 Advanced OC offers 672 GB/s. The VRAM on the RTX 5080 OC is also higher at 16GB, compared to the 12GB found in the RTX 5070 Advanced OC.

Both products use GDDR7 memory and support Error-Correcting Code (ECC) memory, ensuring data integrity. However, the memory bus width on the RTX 5080 OC is 256-bit, which is wider than the 192-bit memory bus width of the RTX 5070 Advanced OC, contributing to better overall memory performance in the 5080 OC.

Despite these differences, both products share the same GDDR version and ECC support, but the Asus ROG Astral GeForce RTX 5080 OC Edition generally offers higher memory speed, bandwidth, and VRAM capacity when compared to the Colorful iGame GeForce RTX 5070 Advanced OC.

Both the Asus ROG Astral GeForce RTX 5080 OC Edition and the Colorful iGame GeForce RTX 5070 Advanced OC support DirectX 12 Ultimate, OpenGL version 4.6, and OpenCL version 3, ensuring compatibility with a wide range of modern games and applications. Additionally, both GPUs support multi-display technology, ray tracing, 3D rendering, DLSS, and are equipped with Intel Resizable BAR, with neither having support for XeSS (XMX) nor featuring LHR (Lite Hash Rate) capabilities.

Both products also feature RGB lighting and support up to 4 displays, offering a visually customizable and versatile experience for users. Despite the similarities in features, the specifications for these two GPUs are identical in this category.

In summary, the Asus ROG Astral GeForce RTX 5080 OC Edition and the Colorful iGame GeForce RTX 5070 Advanced OC share a very similar set of features, including support for key technologies and multi-display setups, as well as RGB lighting and 4-display support. No significant differences are found in this group.

Both the Asus ROG Astral GeForce RTX 5080 OC Edition and the Colorful iGame GeForce RTX 5070 Advanced OC come with HDMI 2.1b outputs. However, the RTX 5080 OC has two HDMI ports, while the RTX 5070 Advanced OC has only one HDMI port. Both GPUs feature 3 DisplayPort outputs, and neither includes USB-C, DVI, or mini DisplayPort outputs.

In summary, the main difference between the two products in this category is the number of HDMI ports, with the RTX 5080 OC offering two, compared to the RTX 5070 Advanced OC’s single HDMI port.

Overall, both products provide a similar set of output options, but the RTX 5080 OC offers more flexibility in terms of HDMI connections.

Both the Asus ROG Astral GeForce RTX 5080 OC Edition and the Colorful iGame GeForce RTX 5070 Advanced OC are built on the Blackwell GPU architecture and feature a 5 nm semiconductor size. The RTX 5080 OC has a higher Thermal Design Power (TDP) of 360W, compared to the 270W TDP of the RTX 5070 Advanced OC. Both products use PCIe version 5 for connectivity, ensuring high bandwidth and low latency for data transfer.

The Asus ROG Astral GeForce RTX 5080 OC Edition has a larger physical size, measuring 357.6 mm in width and 149.3 mm in height, while the Colorful iGame GeForce RTX 5070 Advanced OC is smaller with a width of 330 mm and a height of 140 mm.

In terms of transistor count, the RTX 5080 OC has 45,600 million transistors, which is higher than the 31,100 million found in the RTX 5070 Advanced OC. Neither GPU features air-water cooling, both relying on standard cooling solutions.
