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 645

2010

Why buy it

  • Costs $50 less on MSRP ($150 MSRP vs $200 MSRP).
  • Delivers 31% more G3D Mark for each dollar spent, at 12.5 vs 9.6 G3D/$ ($150 MSRP vs $200 MSRP).

Trade-offs

  • Less VRAM, with 1 GB vs 2 GB for high-resolution textures and newer games.
  • Very weak future-proofing: 2010-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
  • 700% higher power demand at 200W vs 25W.

Quadro M520

2017

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).
  • Draws 25W instead of 200W, a 175W reduction.
  • More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

  • Very weak future-proofing: 2017-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
  • 33.3% HIGHER MSRP
    $200 MSRPvs$150 MSRP
  • Lower G3D Mark per dollar, at 9.6 vs 12.5 G3D/$ ($200 MSRP vs $150 MSRP).

Quick Answers

So, is Quadro M520 better than GeForce GTX 645?
Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 1,880 vs 1,913 in G3D Mark. The bigger reason to prefer Quadro M520 is the overall package: you are getting a newer generation, no meaningful modern upscaling stack, plus much lower power draw (25W vs 200W).
Which one is more future-proof for 2026 and beyond?
GeForce GTX 645 is the safer long-term GPU choice because it gives you the stronger overall hardware and feature outlook for modern games.
Which one is the smarter buy today, not just the cheaper card?
Quadro M520 is the smarter buy by a wide margin. Quadro M520 is about 33.3% more expensive on MSRP at $200 MSRP versus $150 MSRP, and you are getting 1.8% higher G3D Mark. GeForce GTX 645 really only makes sense now as a very cheap stopgap or a used-market placeholder.
When does GeForce GTX 645 make more sense than Quadro M520?
Yes. GeForce GTX 645 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 future-proofing and staying closer to $150 MSRP more than squeezing out the extra headroom of Quadro M520. The trade-off is that Quadro M520 currently gives you 1.8% higher G3D Mark. GeForce GTX 645 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
