In terms of raw performance, the Galax GeForce RTX 5090 D 1-Click OC and the Inno3D GeForce RTX 5090 X3 are nearly identical across the board. Both cards share the same 2017 MHz base clock and 2407 MHz boost clock, the same 21,760 shading units, 680 TMUs, 176 ROPs, and identical 1750 MHz memory speed. This is expected given they are built on the same GPU die, but it also means neither card has been factory-tuned to pull ahead in clock speed or memory bandwidth.

The only measurable difference between the two lies in the texture rate: the Galax reports 1637 GTexels/s versus the Inno3D's 1636.8 GTexels/s — a delta of just 0.2 GTexels/s. This is a rounding-level discrepancy with absolutely no perceptible real-world impact on texture throughput or rendering performance. Similarly, both deliver identical 423.6 GPixel/s pixel fill rate and 104.8 TFLOPS of floating-point performance, and both support Double Precision Floating Point (DPFP), which benefits scientific computing and certain professional workloads.

In conclusion, these two cards are effectively performance-tied in this category. The texture rate difference is purely a matter of decimal rounding and should not factor into any purchasing decision. Buyers should look to other specification groups — such as cooling, design, or connectivity — to differentiate between these two otherwise compute-equivalent GPUs.
