主な違い

• Memory bandwidth is the elephant in the room: the MSI pushes 896 GB/s over a 256-bit bus with GDDR7, while the XFX is stuck at 322 GB/s on a 128-bit GDDR6 bus. That's nearly 3x the bandwidth and it shows in every benchmark.
• Ray tracing and AI hardware are wildly different: the MSI has 70 RT cores and 280 Tensor cores versus 32 and 64 on the XFX. If you care about DLSS 4, multi-frame generation, or ray-traced games, this isn't even close.
• Real-world performance gap is massive: PassMark G3D scores are 32,373 vs 19,749, and 4K gaming scores are 96 vs 63. The MSI is roughly 60-65% faster in actual games.
• The XFX does win on boost clock (3,320 MHz vs 2,482 MHz) and FP16 compute (51.3 vs 43.9 TFLOPS), so it's not a total wash. But FP32, which matters more for gaming, goes to the MSI at 43.9 vs 25.6 TFLOPS.
• Customer sentiment backs up the specs: the MSI has 906 reviews at 4.6/5 with owners praising cooling, quiet operation, and 1440p/4K performance. The XFX only has 4 reviews, so you're taking a bigger leap of faith there.
