At their core, both the Vanguard OC and the Vanguard SOC share identical foundational hardware: the same 4608 shading units, 144 TMUs, 48 ROPs, and a 1750 MHz memory speed. This means the two cards are built on the exact same silicon configuration, and any performance difference between them comes down entirely to how aggressively the GPU boost clock has been tuned at the factory.
That is where the SOC pulls ahead. Its GPU turbo clock of 2692 MHz outpaces the OC's 2647 MHz by 45 MHz — a modest but real gap. This higher sustained boost directly flows through to every throughput metric: the SOC delivers 24.81 TFLOPS of floating-point performance versus 24.39 TFLOPS on the OC, a 387.6 GTexels/s texture fill rate versus 381.2, and a pixel rate of 129.2 GPixel/s versus 127.1. In practice, the ~1.7% throughput advantage is unlikely to produce measurable frame-rate differences in most games, but it does suggest the SOC's cooling solution is validated to sustain a slightly higher operating point under sustained load.
The Vanguard SOC has a clear, if narrow, performance edge in this group. Both cards are otherwise identical in architecture and memory subsystem, so the SOC's advantage is purely clock-driven. For users prioritising peak theoretical throughput and a higher factory boost ceiling, the SOC is the stronger choice; those indifferent to a sub-2% performance delta will find the OC essentially equivalent in real-world use.
