主な違い

• Raw performance is a blowout: the MSI scores 28,796 on PassMark G3D and 14,588 on GPU Compute, while the HyperRender manages 8,788 and 3,438. The MSI is over 3x faster in real-world benchmarks.
• The MSI has 12GB of GDDR7 on a 192-bit bus with 672 GB/s of bandwidth. The RX 580 has 8GB of much older GDDR5 on a 256-bit bus with 504 GB/s. The wider bus on the RX 580 doesn't make up for the ancient memory tech.
• Customer sentiment tells a very different story: the MSI gets a 4.6/5 from 424 reviews with users praising its quiet operation and strong 2K performance, while the RX 580 sits at 3.8/5 with multiple verified buyers reporting display artifacts, black screens, and non-functional ports.
• The MSI's boost clock of 2,557 MHz crushes the RX 580's 1,286 MHz, and the MSI has 48 RT cores for ray tracing while the RX 580 has none. If you care about modern features like DLSS or ray tracing, the RX 580 isn't even in the conversation.
• Value is tricky here: the RX 580 is dirt cheap and fine for basic 1080p, but the MSI's 88/100 budget score vs the RX 580's 31/100 suggests you're getting way more performance per dollar with the MSI, assuming you can afford the higher upfront cost.
