Both cards share an identical architectural foundation — 2048 shading units, 128 TMUs, and 64 ROPs — meaning any performance gap between them comes down entirely to clock speeds, not hardware configuration. This makes the comparison clean: it is a straight factory overclock contest on the same silicon.
And on that front, the Gigabyte Radeon RX 9060 XT Gaming OC holds a consistent and meaningful lead. Its base clock of 1900 MHz runs 200 MHz higher than the Asus Prime OC's 1700 MHz, and its boost clock of 3320 MHz outpaces the Asus's 3130 MHz by 190 MHz — roughly a 6% advantage sustained across all derived throughput metrics. This translates directly into a higher pixel fill rate (212.5 vs. 200.3 GPixel/s), better texture throughput (425 vs. 400.6 GTexels/s), and notably more compute headroom (27.2 vs. 25.64 TFLOPS). In real-world terms, a 6% clock advantage at this tier can mean a few extra frames per second in GPU-bound scenarios and slightly more breathing room in compute-heavy workloads like ray tracing or AI-accelerated features.
Memory bandwidth is a non-factor here — both cards run at an identical 2518 MHz memory speed, and both support Double Precision Floating Point, which is relevant for professional or scientific compute tasks. The edge in this group belongs clearly to the Gigabyte Gaming OC, which delivers a consistent factory overclock advantage across every performance metric, making it the stronger choice for users who want maximum out-of-box performance without manual tuning.
