Asus ROG Astral GeForce RTX 5080 VS Inno3D GeForce RTX 5080 X3 Gaming OC

Both cards are built on the same RTX 5080 silicon, and it shows: they share an identical foundation of 10,752 shading units, 336 TMUs, 112 ROPs, and a base GPU clock of 2295 MHz. This means any performance difference between the two comes down entirely to how aggressively each manufacturer has pushed the boost clock — not architectural variation.

That is where the Inno3D GeForce RTX 5080 X3 Gaming OC pulls ahead. Its 2700 MHz GPU turbo outpaces the Asus ROG Astral's 2640 MHz by 60 MHz — a roughly 2.3% higher ceiling. This gap ripples directly into every derived performance metric: the X3 Gaming OC delivers 58.06 TFLOPS of floating-point throughput versus 56.77 TFLOPS, a 302.4 GPixel/s pixel rate versus 295.7 GPixel/s, and 907.2 GTexels/s texture throughput against 887 GTexels/s. In practice, a ~2% compute advantage of this kind translates to marginally higher sustained frame rates in GPU-bound scenarios, particularly at high resolutions where the GPU is the clear bottleneck.

In terms of raw performance, the Inno3D X3 Gaming OC holds a clear, if modest, edge in this group, driven purely by its higher factory boost clock. Both cards support Double Precision Floating Point, and their memory subsystems are identical at 1875 MHz, so the Inno3D's lead is real but narrow — meaningful for enthusiasts chasing every last frame, but unlikely to be perceptible in everyday gaming workloads.

The memory specifications of the Asus ROG Astral GeForce RTX 5080 and the Inno3D GeForce RTX 5080 X3 Gaming OC are identical across all key areas. Both products feature an effective memory speed of 30000 MHz, ensuring high-speed data transfer. Additionally, each card has a maximum memory bandwidth of 960 GB/s, allowing for quick access to memory resources.

Both models are equipped with 16GB of VRAM, offering substantial memory capacity for demanding graphical workloads. The GDDR7 memory version is used in both cards, further enhancing their overall performance potential. Furthermore, both models share a 256-bit memory bus width, facilitating efficient memory access.

Both products also support Error Correcting Code (ECC) memory, providing a layer of reliability by detecting and correcting memory errors during operation.

The Asus ROG Astral GeForce RTX 5080 and the Inno3D GeForce RTX 5080 X3 Gaming OC have identical feature sets across the board. Both models support DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, ensuring compatibility with modern software and APIs. Both cards also offer support for multi-display technology, ray tracing, 3D, and DLSS, providing an immersive and cutting-edge gaming experience.

Neither model includes XeSS (XMX) support, but both feature Intel Resizable BAR (part of AMD SAM/Intel Resizable BAR), allowing for enhanced performance with compatible CPUs. Additionally, both the Asus and Inno3D models are free from LHR (Lite Hash Rate), making them equally suitable for tasks beyond gaming, such as cryptocurrency mining.

RGB lighting is present on both products, adding a customizable visual flair to your system. Finally, both cards support up to 4 displays, offering ample connectivity for users with multi-monitor setups.

The Asus ROG Astral GeForce RTX 5080 and the Inno3D GeForce RTX 5080 X3 Gaming OC both come equipped with HDMI 2.1b outputs, but there is a difference in the number of HDMI ports. The Asus model features 2 HDMI ports, while the Inno3D version includes just 1 HDMI port. Both cards offer 3 DisplayPort outputs, providing solid options for multi-display setups.

Neither of the two products includes USB-C ports, DVI outputs, or mini DisplayPort outputs, indicating a similar lack of these specific connections on both models.

Both the Asus ROG Astral GeForce RTX 5080 and the Inno3D GeForce RTX 5080 X3 Gaming OC share the same GPU architecture, Blackwell, and feature a thermal design power (TDP) of 360W. They are both built with a 5 nm semiconductor size and contain the same number of transistors, 45600 million. Additionally, both models use PCI Express 5.0 for faster data transfer.

Neither product includes air-water cooling, indicating that they rely on standard cooling solutions. However, there are size differences: the Asus model is wider, measuring 357.6 mm, and taller, at 149.3 mm, compared to the Inno3D model which is 300 mm wide and 120 mm tall.
