GeForce GT 640M

2012

Why buy it

✅Draws 32W instead of 170W, a 138W reduction.

Trade-offs

❌Lower average FPS than GeForce RTX 3060 Laptop GPU across 50 tracked games in our benchmark data.
❌Less VRAM, with 2 GB vs 6 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on Upscaling support instead.
❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

GeForce RTX 3060 Laptop GPU

2022

Why buy it

✅1434.4% more average FPS across 50 tracked games in our benchmark data.
✅Access to DLSS 2 Super Resolution (2020).
✅200% more VRAM for high-resolution textures and newer games (6 GB vs 2 GB).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 3060 Laptop GPU is the faster gaming card right now. In our data, it leads by 1434.4% in average FPS across 50 tracked games in our benchmark data and by 1352% in PassMark G3D (13,170 vs 907), so the answer here is pretty clean.

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

GeForce RTX 3060 Laptop GPU is the safer long-term pick for 2026 and beyond. The case is simple: 6 GB vs 2 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 Laptop GPU makes the most sense today based on the pricing and value data we have for this matchup.
