GeForce GTX 1660 Ti with Max-Q Design vs Radeon RX 580: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce GTX 1660 Ti with Max-Q Design

2019

Why buy it

✅Radeon RX 580 is already legacy-tier future-proofing, so GeForce GTX 1660 Ti with Max-Q Design is the less risky modern option long term.
✅Draws 60W instead of 185W, a 125W reduction.
✅More future proof: Turing (2018−2022) on 12nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than Radeon RX 580 across 50 tracked games in our benchmark data.
❌Less VRAM, with 6 GB vs 8 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌Older hardware, 6 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌Lower G3D Mark per dollar, at 0 vs 38.4 G3D/$ (Unknown MSRP vs $229 MSRP).

Radeon RX 580

2017

Why buy it

✅6.3% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 38.4 vs 0 G3D/$ ($229 MSRP vs Unknown MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅33.3% more VRAM for high-resolution textures and newer games (8 GB vs 6 GB).

Trade-offs

❌2017 hardware with 8 GB of VRAM already sits in legacy territory for modern games.
❌208.3% higher power demand at 185W vs 60W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 580 is the faster gaming card right now. In our data, it leads by 6.3% in average FPS across 50 tracked games in our benchmark data and by 2.4% in PassMark G3D (8,799 vs 8,589), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce GTX 1660 Ti with Max-Q Design is the safer long-term pick for 2026 and beyond. The case is simple: a 12nm process instead of 14nm and a newer 2019 generation instead of 2017. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon RX 580 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Radeon RX 580 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce GTX 1660 Ti with Max-Q Design has the stronger long-term case.
