GeForce GT 640

2012

Why buy it

✅Costs $250 less on MSRP ($99 MSRP vs $349 MSRP).
✅Draws 65W instead of 160W, a 95W reduction.
✅Measures 145mm instead of 229mm, a 84mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than GeForce RTX 2060 across 42 tracked games in our benchmark data.
❌Less VRAM, with 4 GB vs 6 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 40.4 G3D/$ ($99 MSRP vs $349 MSRP).

GeForce RTX 2060

2019

Why buy it

✅1181.0% more average FPS across 42 tracked games in our benchmark data.
✅Delivers 242.5% more G3D Mark for each dollar spent, at 40.4 vs 11.8 G3D/$ ($349 MSRP vs $99 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅50% more VRAM for high-resolution textures and newer games (6 GB vs 4 GB).
✅More future proof: Turing (2018−2022) on 12nm with a newer platform for upcoming games.

Trade-offs

❌146.2% higher power demand at 160W vs 65W.
❌57.9% longer card at 229mm vs 145mm.

Quick Answers

So, is GeForce RTX 2060 better than GeForce GT 640?

Yes. GeForce RTX 2060 is clearly the better overall GPU here. GeForce RTX 2060 averages 1181.0% more FPS across 42 tracked games in our benchmark data. You are also looking at 14,114 vs 1,169 in G3D Mark. On top of that, GeForce RTX 2060 is a 2019 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 2060 is the more future-proof choice for 2026 and beyond. You are getting a newer 2019 generation instead of 2012, 1107.4% more raw performance headroom, more VRAM at 6 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 2060 is the smarter buy by a wide margin. GeForce RTX 2060 is about 252.5% more expensive on MSRP at $349 MSRP versus $99 MSRP, and you are getting 1181.0% more estimated average FPS across 42 tracked games in our benchmark data and 1107.4% 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.
