GeForce GT 640

2012

Why buy it

✅Costs $70 less on MSRP ($99 MSRP vs $169 MSRP).
✅Measures 145mm instead of 160mm, a 15mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower PassMark G3D performance (1,169 vs 10,749).
❌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 63.6 G3D/$ ($99 MSRP vs $169 MSRP).

GeForce RTX 3050 6GB

2024

Why buy it

✅+819.5% higher PassMark G3D performance.
✅Delivers 438.6% more G3D Mark for each dollar spent, at 63.6 vs 11.8 G3D/$ ($169 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: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.

Trade-offs

❌10.3% longer card at 160mm vs 145mm.

Quick Answers

So, is GeForce RTX 3050 6GB better than GeForce GT 640?

Yes. GeForce RTX 3050 6GB is clearly the better overall GPU here. You are also looking at 10,749 vs 1,169 in G3D Mark. On top of that, GeForce RTX 3050 6GB is a 2024 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 3050 6GB is the more future-proof choice for 2026 and beyond. You are getting a newer 2024 generation instead of 2012, 819.5% 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 3050 6GB is the smarter buy by a wide margin. GeForce RTX 3050 6GB is about 70.7% more expensive on MSRP at $169 MSRP versus $99 MSRP, and you are getting 819.5% 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.
