主な違い

• VRAM is the headline: 12GB GDDR7 on the MSI vs 24GB GDDR6 on the Sapphire. The Sapphire's older memory type but double the capacity and a 384-bit bus gives it 960 GB/s bandwidth vs 672 GB/s on the MSI.
• Raw compute isn't close. The Sapphire pushes 61.4 FP32 TFLOPS and 122.8 FP16 TFLOPS, while the MSI manages 30.9 for both. That's why the Sapphire scores 89 for 4K gaming vs the MSI's 78.
• Power draw is a real trade-off. The MSI sips 250W and owners praise it for quiet, cool operation in compact builds. The Sapphire pulls 370W with spikes up to 400W, and reviewers say you'll want an 800W PSU minimum, 1000W to be safe.
• Price-to-performance tells the story. The MSI wins the budget score 85 to 74, and its 4.8/5 rating from owners reflects strong value at MSRP. The Sapphire's 4.4/5 from 717 reviews shows people love the performance but grumble about power needs and occasional driver quirks.
• AI and workstation tasks favor the Sapphire hard: 83 vs 59 for AI/LLM workloads and 77 vs 68 for workstation use. If you're doing local AI inference or heavy 3D rendering, the 24GB VRAM is the deciding factor.
