GeForce GT 640 vs GeForce RTX 3060: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

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 50 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.
❌2012 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 11.8 vs 51.7 G3D/$ ($99 MSRP vs $329 MSRP).

GeForce RTX 3060

2021

Why buy it

✅1353.2% more average FPS across 50 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).
✅Better long-term bet: Ampere on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

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

Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 3060 is the faster gaming card right now. In our data, it leads by 1353.2% in average FPS across 50 tracked games in our benchmark data and by 1353.8% in PassMark G3D (16,995 vs 1,169), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce RTX 3060 is the safer long-term pick for 2026 and beyond. The case is simple: 12 GB vs 4 GB of VRAM, the newer upscaling stack, DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack, a 8nm process instead of 28nm, and 28 vs 0 ray-tracing units. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce RTX 3060 makes the most sense to buy today. It is $230 more expensive on MSRP at $329 vs $99, and it leads G3D-per-dollar by 337.5% (51.7 vs 11.8), so the value case lines up with the gaming result.
