At their core, both cards share an identical hardware foundation: the same 2280 MHz base clock, 3840 shading units, 120 TMUs, 48 ROPs, and 1750 MHz memory speed. This means the underlying silicon is the same, and any performance difference between them comes down entirely to how aggressively each manufacturer has tuned the boost behavior.
That is where the Asus Dual OC Edition separates itself. Its GPU turbo of 2535 MHz outpaces the Inno3D Twin X2's 2497 MHz — a 38 MHz advantage that flows directly into every derived metric. The Asus card delivers 19.47 TFLOPS of floating-point throughput versus 19.18 TFLOPS, a 304.2 GTexels/s texture rate against 299.6 GTexels/s, and a 121.7 GPixel/s pixel fill rate compared to 119.9 GPixel/s. In real-world terms, a higher boost clock means the GPU can sustain faster computation during demanding workloads — translating to marginally better frame rates and responsiveness under load, particularly in GPU-bound scenarios.
The differences are modest — roughly 1.5% across all throughput metrics — so neither card represents a fundamentally different tier of performance. Both also support Double Precision Floating Point (DPFP), which matters for compute workloads beyond gaming. That said, based strictly on the provided specs, the Asus Dual OC Edition holds a clear, consistent edge in every performance metric in this group, thanks solely to its higher factory overclock on the boost frequency.
