GeForce GTX 645 vs GeForce RTX 2060: 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 GTX 645

2010

Why buy it

  • Costs $199 less on MSRP ($150 MSRP vs $349 MSRP).
  • Measures 147mm instead of 229mm, a 82mm 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 1 GB vs 6 GB for high-resolution textures and newer games.
  • No DLSS support; it relies on Upscaling support instead.
  • 2010 hardware with 1 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 12.5 vs 40.4 G3D/$ ($150 MSRP vs $349 MSRP).

GeForce RTX 2060

2019

Why buy it

  • 324.6% more average FPS across 50 tracked games in our benchmark data.
  • Delivers 222.7% more G3D Mark for each dollar spent, at 40.4 vs 12.5 G3D/$ ($349 MSRP vs $150 MSRP).
  • Access to DLSS 2 Super Resolution (2020).
  • 500% more VRAM for high-resolution textures and newer games (6 GB vs 1 GB).
  • Better long-term bet: Turing (2018−2022) on 12nm gives it a newer hardware base for upcoming games.

Trade-offs

  • 55.8% longer card at 229mm vs 147mm.

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 324.6% in average FPS across 50 tracked games in our benchmark data and by 650.7% in PassMark G3D (14,114 vs 1,880), 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 1 GB of VRAM, the newer upscaling stack, DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack, a 12nm process instead of 40nm, 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 $199 more expensive on MSRP at $349 vs $150, and it leads G3D-per-dollar by 222.7% (40.4 vs 12.5), so the value case lines up with the gaming result.
