About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, raw graphics performance, VRAM, feature set, power efficiency, pricing context, and long-term value so you can see which GPU actually makes more sense.

GeForce GTX 1660 Ti (Mobile)

2020

Why buy it

  • ✅Draws 50W instead of 72W, a 22W reduction.

Trade-offs

  • ❌Less VRAM, with 6 GB vs 8 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.
  • ❌Lower G3D Mark per dollar, at 0 vs 4.3 G3D/$ (Unknown MSRP vs $2,345 MSRP).

L4

2023

Why buy it

  • ✅Delivers 100+% more G3D Mark for each dollar spent, at 4.3 vs 0 G3D/$ ($2,345 MSRP vs Unknown MSRP).
  • ✅33.3% more VRAM for high-resolution textures and newer games (8 GB vs 6 GB).
  • ✅More future proof: Ada Lovelace (2022−2024) on 5nm with a newer platform for upcoming games.

Trade-offs

  • ❌44% higher power demand at 72W vs 50W.

Quick Answers

So, is L4 better than GeForce GTX 1660 Ti (Mobile)?
Yes. L4 is clearly the better overall GPU here. You are also looking at 10,153 vs 10,119 in G3D Mark. On top of that, L4 is a 2023 card with no meaningful modern upscaling stack, while GeForce GTX 1660 Ti (Mobile) is a 2020 model from an older generation with no meaningful modern upscaling stack. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.
Which one is more future-proof for 2026 and beyond?
L4 is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2020, more VRAM at 8 GB instead of 6 GB, 100.0% more ray-tracing hardware, and a 5nm 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?
L4 can still make sense if you find it at the right price, especially around $2,345 MSRP. L4 is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. L4 is priced in an unclear MSRP range at $2,345 MSRP versus an unclear MSRP, and you are getting 0.3% higher G3D Mark. Moving to $2,345 MSRP gets you newer hardware, and no meaningful modern upscaling stack.
Is GeForce GTX 1660 Ti (Mobile) still worth buying for gaming in 2026?
Yes. GeForce GTX 1660 Ti (Mobile) is still a strong gaming card in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. Price is really the swing factor here. If you find it at or below an unclear MSRP, it remains a very sensible buy. L4 is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and no meaningful modern upscaling stack.
