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

✅Delivers 100+% more G3D Mark for each dollar spent, at 11.8 vs 0 G3D/$ ($99 MSRP vs Unknown MSRP).
✅Draws 65W instead of 160W, a 95W reduction.

Trade-offs

❌Lower average FPS than GeForce RTX 4060 Laptop GPU across 50 tracked games in our benchmark data.
❌Less VRAM, with 4 GB vs 8 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.

GeForce RTX 4060 Laptop GPU

2023

Why buy it

✅Access to a newer frame-generation stack with DLSS 3.5 + Frame Generation (2023).
✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).
✅More future proof: Ada Lovelace (2022−2024) on 5nm with a newer platform for upcoming games.

Trade-offs

❌Lower G3D Mark per dollar, at 0 vs 11.8 G3D/$ (Unknown MSRP vs $99 MSRP).

Quick Answers

So, is GeForce RTX 4060 Laptop GPU better than GeForce GT 640?

Yes. GeForce RTX 4060 Laptop GPU is clearly the better overall GPU here. GeForce RTX 4060 Laptop GPU averages 1630.0% more FPS across 50 tracked games in our benchmark data. You are also looking at 17,400 vs 1,169 in G3D Mark. On top of that, GeForce RTX 4060 Laptop GPU is a 2023 card with DLSS 3.5 + Frame Generation, 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 4060 Laptop GPU is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2012, 1388.5% more raw performance headroom, more VRAM at 8 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 4060 Laptop GPU is the smarter buy by a wide margin. GeForce RTX 4060 Laptop GPU is priced in an unclear MSRP range at an unclear MSRP versus $99 MSRP, and you are getting 1630.0% more estimated average FPS across 50 tracked games in our benchmark data and 1388.5% 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.
