主な違い

• Raw gaming performance is a blowout: the PNY scores 93 for 1080p and 90 for 4K, while the B580 manages 53 and 47. You're getting roughly double the frame rates in most titles.
• VRAM and bandwidth tell the story: 16GB of GDDR7 on a 256-bit bus with 896 GB/s bandwidth versus 12GB of GDDR6 on a 192-bit bus with 504 GB/s. The PNY has a massive memory advantage for high-res textures and future games.
• Ray tracing is barely a contest: 70 RT cores on the PNY versus 20 on the B580, and the scores reflect it at 89 vs 49. If you care about RT effects, the Intel card will struggle.
• Price is the B580's whole identity. At around $250 it's less than a third of the 5070 Ti's cost, and owners consistently call it the best value GPU on the market right now.
• Real-world feedback is surprisingly close: both cards sit at 4.6-4.7 stars and 82/100 sentiment. PNY owners praise the cool, quiet operation and easy install, while B580 owners love the value but note driver support is still maturing.
