Asus ROG Astral LC GeForce RTX 5090 OC Edition VS Inno3D GeForce RTX 5090 X3 OC

Both cards share the same foundation: identical base clocks of 2017 MHz, the same 21,760 shading units, 680 TMUs, 176 ROPs, and matched memory speeds of 1750 MHz. This means they are built on the same silicon with the same theoretical throughput ceiling — the real story is entirely in how aggressively each manufacturer has pushed the boost clock.

That is where the Asus ROG Astral LC pulls decisively ahead. Its GPU turbo reaches 2580 MHz versus the Inno3D X3 OC's 2452 MHz — a gap of 128 MHz, or roughly 5.2%. Because pixel fill rate, texture throughput, and floating-point performance all scale linearly with clock speed on identical silicon, this single difference cascades across every derived metric: the ROG delivers 112.3 TFLOPS of FP32 compute and a texture rate of 1754 GTexels/s, compared to 106.7 TFLOPS and 1667.4 GTexels/s on the Inno3D. In practice, that translates to a measurable, consistent throughput advantage in GPU-bound workloads — ray tracing, AI inference, and high-resolution rasterization alike.

The Asus ROG Astral LC holds a clear performance edge in this group, and its advantage is not a rounding quirk — it is a sustained, clock-driven lead that will be visible in benchmarks. The Inno3D X3 OC is by no means slow, but buyers prioritizing raw compute headroom should favour the ROG. Both cards support Double Precision Floating Point, which matters for professional and scientific workloads, so that capability is a non-differentiator here.

The Asus ROG Astral LC GeForce RTX 5090 OC Edition and the Inno3D GeForce RTX 5090 X3 OC are closely matched in terms of memory specifications. Both models feature an effective memory speed of 28000 MHz, ensuring equivalent performance in terms of memory access speed.

The maximum memory bandwidth is nearly identical, with the Asus model offering 1790 GB/s and the Inno3D model slightly edging ahead at 1792 GB/s. Both products come with 32GB of VRAM, and both use GDDR7 memory, ensuring high-speed performance across the board.

Both products also share the same 512-bit memory bus width, which facilitates fast data transfer across the memory system. Additionally, both cards support Error-Correcting Code (ECC) memory, offering enhanced reliability during heavy workloads and reducing the risk of memory errors.

The Asus ROG Astral LC GeForce RTX 5090 OC Edition and the Inno3D GeForce RTX 5090 X3 OC offer identical feature sets. Both models support DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, ensuring compatibility with a wide range of modern software and applications.

Both products also support multi-display technology, ray tracing, and 3D, providing immersive visuals and versatile display options. They are compatible with DLSS for improved performance in supported games, and neither card includes XeSS (XMX) support.

For system compatibility, both cards support Intel Resizable BAR and feature no LHR (Lite Hash Rate), ensuring full mining potential. Additionally, both models feature RGB lighting and support up to four displays, making them ideal for multi-monitor setups.

The Asus ROG Astral LC GeForce RTX 5090 OC Edition and the Inno3D GeForce RTX 5090 X3 OC both include HDMI 2.1b outputs. However, the Asus model provides two HDMI ports, while the Inno3D model has only one HDMI port.

Both products feature three DisplayPort outputs, ensuring compatibility with a variety of display setups. Neither card includes USB-C, DVI, or mini DisplayPort outputs, meaning their video output options are limited to HDMI and DisplayPort.

In summary, the main difference between the two cards in this group is the number of HDMI ports, with the Asus model offering a greater number of ports for HDMI-based displays.

Both the Asus ROG Astral LC GeForce RTX 5090 OC Edition and the Inno3D GeForce RTX 5090 X3 OC share identical GPU architecture (Blackwell), thermal design power (TDP) of 575W, PCIe version 5, semiconductor size of 5 nm, and number of transistors (92,200 million), meaning the core specifications of these two cards are identical in terms of processing power and energy consumption.

One key difference lies in cooling: the Asus model features air-water cooling, while the Inno3D model lacks this feature, relying solely on air cooling. This distinction could affect thermal performance and noise levels under load.

In terms of physical dimensions, the Asus card is 288.5 mm in width and 153.7 mm in height, whereas the Inno3D model is slightly wider at 333 mm and shorter in height at 137 mm. These differences in size could influence case compatibility depending on available space.
