GeForce GTX 680M SLI

2012

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

  • Very weak future-proofing: 2012-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
  • Lower G3D Mark per dollar, at 0 vs 23.3 G3D/$ (Unknown MSRP vs $150 MSRP).
  • 150% higher power demand at 75W vs 30W.

Maxwell GPU Surface Book (940M, GDDR5)

2015

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 23.3 vs 0 G3D/$ ($150 MSRP vs Unknown MSRP).
  • Draws 30W instead of 75W, a 45W reduction.
  • More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

  • Very weak future-proofing: 2015-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.

Quick Answers

So, is GeForce GTX 680M SLI better than Maxwell GPU Surface Book (940M, GDDR5)?
Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 3,569 vs 3,500 in G3D Mark. The bigger reason to prefer GeForce GTX 680M SLI is the overall package: you are getting no meaningful modern upscaling stack.
Which one is more future-proof for 2026 and beyond?
GeForce GTX 680M SLI 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?
GeForce GTX 680M SLI is the smarter buy by a wide margin. GeForce GTX 680M SLI is priced in an unclear MSRP range at an unclear MSRP versus $150 MSRP, and you are getting 2.0% higher G3D Mark. Maxwell GPU Surface Book (940M, GDDR5) really only makes sense now as a very cheap stopgap or a used-market placeholder.
When does Maxwell GPU Surface Book (940M, GDDR5) make more sense than GeForce GTX 680M SLI?
Yes. Maxwell GPU Surface Book (940M, GDDR5) 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 (30W vs 75W), and staying closer to $150 MSRP more than squeezing out the extra headroom of GeForce GTX 680M SLI. The trade-off is that GeForce GTX 680M SLI currently gives you 2.0% higher G3D Mark. Maxwell GPU Surface Book (940M, GDDR5) still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
