Quick Answers

So, is Radeon PRO W6600M better than GeForce GTX 1660?

Yes. Radeon PRO W6600M is the better GPU overall here. You are getting 13.4% more average FPS across 50 tracked games in our benchmark data, 2% higher PassMark G3D performance, and 8 GB vs 6 GB of VRAM. It also comes from 2021 instead of 2019, which helps its case as the more complete modern gaming card.

Which one is more future-proof for 2026 and beyond?

Radeon PRO W6600M is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2019, more VRAM at 8 GB instead of 6 GB, better upscaling support with FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, and a 7nm process instead of 12nm. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.

Which one is the smarter buy today, not just the cheaper card?

Radeon PRO W6600M is priced in an unclear MSRP range at an unclear MSRP versus $219 MSRP, and you are getting 13.4% more estimated average FPS across 50 tracked games in our benchmark data and a lower G3D Mark (11,407 vs 11,639). GeForce GTX 1660 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium. If you are comfortable paying the premium for the stronger gaming result, Radeon PRO W6600M is the one to buy. If staying closer to budget matters more, GeForce GTX 1660 still makes more sense on price alone, but the performance trade-off is much harder to justify by current standards.

Is GeForce GTX 1660 still worth buying for gaming in 2026?

Yes. GeForce GTX 1660 is still a strong gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. This mostly comes down to price. If you want to stay closer to $219 MSRP, it remains a strong choice; if you are comfortable paying more, Radeon PRO W6600M earns that extra money with a clearly stronger gaming result and a more complete overall package.
