When comparing the performance specs of the Asus ROG Astral RTX 5080 and the Inno3D RTX 5080 X3 OC, the two cards are in complete lockstep. Both share an identical base clock of 2295 MHz and a boost clock of 2640 MHz, meaning neither card has a factory overclock advantage over the other at the spec level provided.

The computational throughput figures reinforce this parity. Both deliver 56.77 TFLOPS of floating-point performance, a pixel rate of 295.7 GPixel/s, and a texture rate of 887 GTexels/s — numbers that place them squarely in high-end territory for rasterization and shader-heavy workloads. The underlying silicon configuration is also shared: 10,752 shading units, 336 TMUs, and 112 ROPs, confirming both cards use the same fully-enabled GPU die with no cut-down variants in play. Memory speed, at 1875 MHz, is also identical, so bandwidth-sensitive tasks like high-resolution texture streaming will behave the same on both boards.

On paper, this group is a dead tie. Neither card holds a performance edge based solely on these specs. Any real-world differentiation between the two — such as sustained boost behavior under thermal load — would come down to cooling design and power delivery rather than the clock speeds themselves, which are not reflected in this data set.
