GeForce GTX 680MX

2012

Why buy it

✅Draws 122W instead of 200W, a 78W reduction.

Trade-offs

❌Lower PassMark G3D performance (3,799 vs 26,919).
❌Less VRAM, with 4 GB vs 12 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like DLSS 3.5 + Frame Generation (2023).
❌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 0 vs 44.9 G3D/$ (Unknown MSRP vs $599 MSRP).

GeForce RTX 4070

2023

Why buy it

✅+608.6% higher PassMark G3D performance.
✅Delivers 100+% more G3D Mark for each dollar spent, at 44.9 vs 0 G3D/$ ($599 MSRP vs Unknown MSRP).
✅Access to a newer frame-generation stack with DLSS 3.5 + Frame Generation (2023).
✅200% more VRAM for high-resolution textures and newer games (12 GB vs 4 GB).
✅More future proof: Ada Lovelace (2022−2024) on 5nm with a newer platform for upcoming games.

Trade-offs

❌63.9% higher power demand at 200W vs 122W.

Quick Answers

So, is GeForce RTX 4070 better than GeForce GTX 680MX?

Yes. GeForce RTX 4070 is clearly the better overall GPU here. You are also looking at 26,919 vs 3,799 in G3D Mark. On top of that, GeForce RTX 4070 is a 2023 card with DLSS 3.5 + Frame Generation, while GeForce GTX 680MX 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 4070 is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2012, 608.6% more raw performance headroom, more VRAM at 12 GB instead of 4 GB, and better upscaling support with DLSS 3.5 Super Resolution (2023) instead of no meaningful modern upscaling stack and better frame-generation support with DLSS 3.5 + Frame Generation (2023) 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 4070 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce RTX 4070 is priced in an unclear MSRP range at $599 MSRP versus an unclear MSRP, and you are getting 608.6% higher G3D Mark. It also leads G3D-per-dollar by 100+%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is GeForce GTX 680MX still worth buying for gaming in 2026?

Yes. GeForce GTX 680MX is still a strong modern gaming GPU: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It remains a good buy when you can get it meaningfully cheaper than the alternative around an unclear MSRP, even if GeForce RTX 4070 is still the cleaner recommendation on overall value today.
