GeForce GTX 1660

2019

Why buy it

✅12.9% more average FPS across 50 tracked games in our benchmark data.
✅Costs $10 less on MSRP ($219 MSRP vs $229 MSRP).
✅Draws 120W instead of 150W, a 30W reduction.
✅Measures 229mm instead of 241mm, a 12mm shorter card that is more SFF-friendly.

Trade-offs

❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌Limited future-proofing: older hardware, 6 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.

Radeon RX 5600

2020

Why buy it

✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅More future proof: RDNA 1.0 (2019−2020) on 7nm with a newer platform for upcoming games.
✅More future proof: RDNA 1.0 (2019−2020) on 7nm with a newer platform for upcoming games.

Quick Answers

So, is Radeon RX 5600 better than GeForce GTX 1660?

Yes. Radeon RX 5600 is the better GPU overall here. You are getting 1% higher PassMark G3D performance. It also comes from 2020 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 RX 5600 is the more future-proof choice for 2026 and beyond. You are getting a newer 2020 generation instead of 2019, better upscaling support with FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack and better frame-generation support with FSR Frame Generation (2023) instead of no meaningful modern upscaling stack, and a 7nm process instead of 12nm. That broader feature stack should age better as more games lean on modern upscaling and frame-generation support.

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

GeForce GTX 1660 is easier to justify on price alone at $219 MSRP, but Radeon RX 5600 is still the stronger gaming card overall. Radeon RX 5600 is about 4.6% more expensive on MSRP at $229 MSRP versus $219 MSRP, and you are getting lower estimated average FPS across 50 tracked games in our benchmark data and 1.0% higher G3D Mark. GeForce GTX 1660 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium. Go with Radeon RX 5600 if you want the better experience; go with GeForce GTX 1660 if keeping cost down matters more than squeezing out the highest performance.

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

Yes. GeForce GTX 1660 is still a very good gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. Around $219 MSRP, it makes sense if you would rather save money than pay about 4.6% more for the extra performance. If you have more room in the budget, Radeon RX 5600 is still the safer long-term pick.

Advanced Features (DLSS/FSR)

A critical advantage for the Radeon RX 5600 is support for FSR Frame Generation. This allows it to generate entire frames using AI/Algorithms, essentially doubling the frame rate in CPU-bound scenarios or heavy ray-tracing titles. The GeForce GTX 1660 lacks specific hardware/driver support for this native frame generation tier.The GeForce GTX 1660 gives access to NVIDIA DLSS (Deep Learning Super Sampling), widely regarding as the superior upscaling method for image quality. The Radeon RX 5600 relies on FSR (FidelityFX Super Resolution), which is capable but generally slightly noisier than DLSS in motion.
