At their core, the Gainward Ghost 8GB and the Galax 1-Click OC 16GB share the same fundamental GPU architecture: identical base clocks of 2407 MHz, the same 4608 shading units, 144 TMUs, 48 ROPs, and matching memory speeds of 1750 MHz. This means both cards are drawing from the exact same silicon well, and any performance delta between them will come down to how aggressively each manufacturer has tuned the boost behavior.
That tuning gives the Galax a measurable, if slim, edge. Its boost clock reaches 2587 MHz versus the Gainward's 2572 MHz — a 15 MHz difference that cascades across every derived throughput metric. The Galax edges ahead with 23.84 TFLOPS of floating-point performance versus 23.7 TFLOPS, a 372.5 GTexels/s texture rate versus 370.4 GTexels/s, and a pixel rate of 124.2 GPixel/s versus 123.5 GPixel/s. In real-world terms, these margins translate to less than a 1% throughput advantage — a gap that will be statistically invisible in gaming frame rates or rendering benchmarks under typical conditions.
Both cards support Double Precision Floating Point (DPFP), which matters for compute workloads like scientific simulations or certain AI tasks rather than gaming. Overall, the Galax 1-Click OC holds a technical performance edge in this group purely on the strength of its higher turbo clock, but the advantage is so narrow that it should carry essentially zero weight in a real-world purchase decision based on raw performance alone — the two cards are, for all practical purposes, performance peers.
