Both cards share the same core silicon architecture — identical 2048 shading units, 128 TMUs, and 64 ROPs — meaning any performance gap between them comes purely from clock speeds, not from hardware configuration differences. This is a factory overclock situation: the XFX Swift ships with a higher base clock of 1900 MHz versus the Asus Dual's 1700 MHz, and a higher boost ceiling of 3320 MHz versus 3230 MHz. In practice, base clock differences matter less in gaming since GPUs spend most of their time near boost, but a higher base does reduce the risk of clock dips during sustained workloads.
The clock advantage translates directly into every throughput metric. The XFX edges ahead with 27.2 TFLOPS of floating-point performance versus 26.46 TFLOPS, and a texture rate of 425 GTexels/s compared to 413.4 GTexels/s. These are roughly a 2.8–3% uplift across the board — real, but modest. In gaming, this margin typically translates to a few frames per second at most, an improvement that will be measurable in benchmarks but unlikely to be perceptible in everyday use. Memory throughput is a non-issue: both cards run identical 2518 MHz GDDR memory, so bandwidth is not a differentiating factor.
The XFX Swift holds a clear, if narrow, performance edge in this group strictly on the basis of its factory overclock. If raw peak throughput is the priority, it wins. That said, the Asus Dual operates on the same die with the same memory subsystem, and the gap is small enough that real-world gaming differences will be marginal — thermal behavior, power limits, and driver conditions could easily close it under sustained load.
