主な違い

• VRAM is the big one: 16GB on the ASUS vs 24GB on the Sapphire. Owners of the ASUS already call the 16GB ceiling a concern, while Sapphire buyers specifically praise the 24GB for future-proofing.
• Ray tracing and upscaling are where the ASUS pulls ahead. It scores 99 vs 90 in ray tracing and has 336 tensor cores vs 192, so if you care about DLSS and RT performance, the Nvidia card is the clear pick.
• Raw compute tells a different story than gaming benchmarks. The Sapphire crushes FP16 at 122.8 TFLOPS vs 56.3, and edges out FP32 too. For content creation or compute-heavy work, the Sapphire has more muscle.
• Customer sentiment favors the Sapphire: 88/100 vs 82/100. ASUS owners complain about the price being above MSRP and mediocre overclocking headroom, while Sapphire owners mostly just warn you need an 850W+ PSU.
• Power draw is close but the Sapphire is slightly more efficient at 339W vs 360W TDP, despite having more VRAM and a wider 384-bit memory bus.
