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 GT 640

2012

Why buy it

  • Costs $300 less on MSRP ($99 MSRP vs $399 MSRP).
  • Draws 65W instead of 200W, a 135W reduction.
  • Measures 145mm instead of 242mm, a 97mm shorter card that is more SFF-friendly.

Trade-offs

  • Lower average FPS than GeForce RTX 3060 Ti across 50 tracked games in our benchmark data.
  • Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
  • No DLSS support; it relies on Upscaling support instead.
  • Very weak future-proofing: 2012-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
  • Lower G3D Mark per dollar, at 11.8 vs 50.9 G3D/$ ($99 MSRP vs $399 MSRP).

GeForce RTX 3060 Ti

2020

Why buy it

  • 1584.3% more average FPS across 50 tracked games in our benchmark data.
  • Delivers 331.1% more G3D Mark for each dollar spent, at 50.9 vs 11.8 G3D/$ ($399 MSRP vs $99 MSRP).
  • Access to DLSS 2 Super Resolution (2020).
  • 100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).
  • More future proof: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.

Trade-offs

  • 207.7% higher power demand at 200W vs 65W.
  • 66.9% longer card at 242mm vs 145mm.

Quick Answers

So, is GeForce RTX 3060 Ti better than GeForce GT 640?
Yes. GeForce RTX 3060 Ti is clearly the better overall GPU here. GeForce RTX 3060 Ti averages 1584.3% more FPS across 50 tracked games in our benchmark data. You are also looking at 20,312 vs 1,169 in G3D Mark. On top of that, GeForce RTX 3060 Ti is a 2020 card with DLSS Super Resolution, while GeForce GT 640 is a 2012 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?
GeForce RTX 3060 Ti is the more future-proof choice for 2026 and beyond. You are getting a newer 2020 generation instead of 2012, 1637.6% more raw performance headroom, more VRAM at 8 GB instead of 4 GB, and better upscaling support with DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack. That leaves it with more room for heavier textures, tougher ray tracing loads, and higher-end 1440p or 4K gaming over the next few years.
Which one is the smarter buy today, not just the cheaper card?
GeForce RTX 3060 Ti is the smarter buy by a wide margin. GeForce RTX 3060 Ti is about 303.0% more expensive on MSRP at $399 MSRP versus $99 MSRP, and you are getting 1584.3% more estimated average FPS across 50 tracked games in our benchmark data and 1637.6% higher G3D Mark. GeForce GT 640 really only makes sense now as a very cheap stopgap or a used-market placeholder.
Is GeForce GT 640 still worth buying for gaming in 2026?
No, not for a fresh gaming build. GeForce GT 640 is 2012 hardware with 4 GB of VRAM, 1,169 in G3D Mark, and no meaningful modern upscaling stack. That is simply too far behind to be an easy modern recommendation.
