GeForce GT 640

2012

Why buy it

✅Costs $200 less on MSRP ($99 MSRP vs $299 MSRP).
✅Draws 65W instead of 115W, a 50W reduction.
✅Measures 145mm instead of 240mm, a 95mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower PassMark G3D performance (1,169 vs 19,548).
❌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.
❌Lower G3D Mark per dollar, at 11.8 vs 65.4 G3D/$ ($99 MSRP vs $299 MSRP).

GeForce RTX 4060

2023

Why buy it

✅+1572.2% higher PassMark G3D performance.
✅Delivers 453.7% more G3D Mark for each dollar spent, at 65.4 vs 11.8 G3D/$ ($299 MSRP vs $99 MSRP).
✅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

❌76.9% higher power demand at 115W vs 65W.
❌65.5% longer card at 240mm vs 145mm.

Quick Answers

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

Yes. GeForce RTX 4060 is clearly the better overall GPU here. You are also looking at 19,548 vs 1,169 in G3D Mark. On top of that, GeForce RTX 4060 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 is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2012, 1572.2% 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 is the smarter buy by a wide margin. GeForce RTX 4060 is about 202.0% more expensive on MSRP at $299 MSRP versus $99 MSRP, and you are getting 1572.2% 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.
