主な違い

• VRAM and memory bus are night and day: the Sapphire packs 24GB on a 384-bit bus with 960 GB/s bandwidth, while the MSI makes do with 16GB on a 128-bit bus at 448 GB/s, which matters a lot at 4K and for AI workloads.
• Raw compute is not even close: the Sapphire hits 61.4 FP32 TFLOPS and 122.8 FP16 TFLOPS versus the MSI's 19.2 in both, and PassMark G3D scores back that up at 31,427 vs 22,099.
• The MSI wins on power and practicality: it runs cool and quiet in small form factor builds and eGPU enclosures, while the Sapphire is a 4-slot card that owners say needs a beefy PSU and occasionally exhibits coil whine.
• Customer sentiment tells an interesting story: the MSI scores 82/100 with users praising its value for older builds, but the Sapphire scores 88/100 with high confidence from 43 evidence sources, and reviewers specifically call out its excellent 4K performance and quiet operation.
• Price is the elephant in the room: the MSI's budget score of 89 vs the Sapphire's 75 means you're paying a serious premium for all that extra performance, so the MSI makes way more sense if you're not pushing past 1440p.
