GeForce GT 640

2012

Why buy it

✅Costs $230 less on MSRP ($99 MSRP vs $329 MSRP).
✅Draws 65W instead of 170W, a 105W reduction.
✅Measures 145mm instead of 242mm, a 97mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than GeForce RTX 3060 across 36 tracked games in our benchmark data.
❌Less VRAM, with 4 GB vs 12 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on Upscaling support instead.
❌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 51.7 G3D/$ ($99 MSRP vs $329 MSRP).

GeForce RTX 3060

2021

Why buy it

✅1738.7% more average FPS across 36 tracked games in our benchmark data.
✅Delivers 337.5% more G3D Mark for each dollar spent, at 51.7 vs 11.8 G3D/$ ($329 MSRP vs $99 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅200% more VRAM for high-resolution textures and newer games (12 GB vs 4 GB).
✅More future proof: Ampere on 8nm with a newer platform for upcoming games.

Trade-offs

❌161.5% higher power demand at 170W vs 65W.
❌66.9% longer card at 242mm vs 145mm.

Quick Answers

So, is GeForce RTX 3060 better than GeForce GT 640?

Yes. GeForce RTX 3060 is clearly the better overall GPU here. GeForce RTX 3060 averages 1738.7% more FPS across 36 tracked games in our benchmark data. You are also looking at 16,995 vs 1,169 in G3D Mark. On top of that, GeForce RTX 3060 is a 2021 card with DLSS Super Resolution, 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 3060 is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2012, 1353.8% more raw performance headroom, more VRAM at 12 GB instead of 4 GB, and better upscaling support with DLSS 2 Super Resolution (2020) 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 3060 is the smarter buy by a wide margin. GeForce RTX 3060 is about 232.3% more expensive on MSRP at $329 MSRP versus $99 MSRP, and you are getting 1738.7% more estimated average FPS across 36 tracked games in our benchmark data and 1353.8% 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.
