主要区别

• The MSI has 6144 CUDA cores to the Gigabyte's 2048, plus 12GB of GDDR7 on a 192-bit bus versus 8GB of GDDR6 on a 128-bit bus. That's 672 GB/s of bandwidth against 192 GB/s.
• Gaming scores tell the story: the MSI hits 94/100 at 1080p and 92/100 at 1440p, while the Gigabyte manages 37 and 32. At 4K it's 81 vs 20. The 3050 isn't a 4K card, period.
• Ray tracing is a blowout too. The MSI has 48 RT cores and scores 88, the Gigabyte has 16 and scores 31. If you care about RT at all, the 3050 is basically a non-starter.
• Real-world sentiment backs this up. The MSI has a 4.7/5 from over 2,000 reviews with owners praising 1440p performance and cool, quiet operation. The Gigabyte sits at 3.3/5 from just 3 reviews, which is a tiny sample but not exactly a ringing endorsement.
• The one thing the Gigabyte has going for it is price and power draw. It's a low-power card that'll run on a modest PSU, while the MSI is a chunky triple-fan card that needs real case space and a decent power supply.
