At the foundation, both the Gigabyte Aero OC and the MSI Ventus 2X OC share the same core hardware configuration: identical base clocks of 2280 MHz, the same 3840 shading units, 120 TMUs, 48 ROPs, and matched memory speeds of 1750 MHz. This means the two cards are built on the same silicon with the same rendering pipeline, and any performance gap between them comes down entirely to how aggressively each manufacturer has factory-overclocked the GPU boost frequency.
That is where the Gigabyte Aero OC pulls ahead. Its boost clock reaches 2595 MHz versus 2527 MHz on the Ventus 2X OC — a difference of 68 MHz, or roughly 2.7%. This directly translates into every derived throughput metric: the Aero OC delivers 19.93 TFLOPS of floating-point performance against 19.41 TFLOPS, a 311.4 GTexels/s texture fill rate versus 303.2, and a pixel rate of 124.6 GPixel/s compared to 121.3. In real-world terms, a ~2.7% clock advantage is unlikely to be perceptible in most gaming scenarios, but it does mean the Aero OC has a slightly higher performance ceiling, which can matter in GPU-bound workloads or compute tasks where every TFLOP counts.
Both cards support Double Precision Floating Point (DPFP), which is relevant for certain professional or scientific compute workloads beyond gaming. Overall, the Gigabyte Aero OC holds a narrow but consistent performance edge in this group, driven purely by its higher factory boost clock. The MSI Ventus 2X OC is not slower by any meaningful gaming margin, but on paper the Aero OC is the faster card of the two.
