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

GeForce GT 640 Rev. 2

2013

Why buy it

✅Costs $250 less on MSRP ($99 MSRP vs $349 MSRP).
✅Draws 49W instead of 160W, a 111W 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 50 tracked games in our benchmark data.
❌Less VRAM, with 512 MB vs 6 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on Upscaling support instead.
❌2013 hardware with 512 MB 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 40.4 G3D/$ ($99 MSRP vs $349 MSRP).

GeForce RTX 2060

2019

Why buy it

✅1090.3% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 242.8% 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).
✅1100% more VRAM for high-resolution textures and newer games (6 GB vs 512 MB).
✅Better long-term bet: Turing (2018−2022) on 12nm gives it a newer hardware base for upcoming games.

Trade-offs

❌226.5% higher power demand at 160W vs 49W.
❌57.9% longer card at 229mm vs 145mm.

Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 2060 is the faster gaming card right now. In our data, it leads by 1090.3% in average FPS across 50 tracked games in our benchmark data and by 1108.4% in PassMark G3D (14,114 vs 1,168), so the answer here is pretty clean.

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

GeForce RTX 2060 is the safer long-term pick for 2026 and beyond. The case is simple: 6 GB vs 512 MB of VRAM, the newer upscaling stack, DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack, a 12nm process instead of 28nm, and 30 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 2060 makes the most sense to buy today. It is $250 more expensive on MSRP at $349 vs $99, and it leads G3D-per-dollar by 242.8% (40.4 vs 11.8), so the value case lines up with the gaming result.
