GeForce GTX 1660

2019

Why buy it

✅Costs $5,480 less on MSRP ($219 MSRP vs $5,699 MSRP).
✅Delivers 2465% more G3D Mark for each dollar spent, at 53.1 vs 2.1 G3D/$ ($219 MSRP vs $5,699 MSRP).
✅Less risky long-term buy than Tesla P40: it remains the more sensible modern option while Tesla P40 is already legacy-tier future-proofing.
✅Draws 120W instead of 250W, a 130W reduction.
✅Measures 229mm instead of 267mm, a 38mm shorter card that is more SFF-friendly.

Trade-offs

❌Less VRAM, with 6 GB vs 24 GB for high-resolution textures and newer games.
❌Limited future-proofing: older hardware, 6 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.

Why buy it

✅300% more VRAM for high-resolution textures and newer games (24 GB vs 6 GB).

Trade-offs

Quick Answers

So, is Tesla P40 better than GeForce GTX 1660?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 11,639 vs 11,808 in G3D Mark. The bigger reason to prefer Tesla P40 is the overall package: you are getting no meaningful modern upscaling stack.

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

GeForce GTX 1660 is the more future-proof choice for 2026 and beyond. You are getting a newer 2019 generation instead of 2016 and a 12nm process instead of 16nm. That makes it the safer long-run choice for modern games.

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

Tesla P40 is the smarter buy by a wide margin. Tesla P40 is about 2502.3% more expensive on MSRP at $5,699 MSRP versus $219 MSRP, and you are getting 1.5% higher G3D Mark. GeForce GTX 1660 really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does GeForce GTX 1660 make more sense than Tesla P40?

Yes. GeForce GTX 1660 is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is newer architecture, lower power draw (120W vs 250W), future-proofing, and staying closer to $219 MSRP more than squeezing out the extra headroom of Tesla P40. The trade-off is that Tesla P40 currently gives you 1.5% higher G3D Mark. GeForce GTX 1660 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.

Games Benchmarks

Real-world benchmarks and performance projections based on comprehensive hardware analysis and comparative metrics. Values represent expected performance on High/Ultra settings at 1080p, 1440p, and 4K. Modeled using a Ryzen 7 9800X3D reference profile to minimize specific CPU bottlenecks.

Note: Performance behavior can vary per game. Specific architectures may perform better or worse depending on game engine optimizations and API implementation.
