GeForce GTX 645 vs GeForce GTX 1650: 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

✅Measures 147mm instead of 229mm, a 82mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than GeForce GTX 1650 across 50 tracked games in our benchmark data.
❌Less VRAM, with 1 GB vs 4 GB for high-resolution textures and newer games.
❌2010 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
0.7% HIGHER MSRP
$150 MSRPvs$149 MSRP
❌Lower G3D Mark per dollar, at 12.5 vs 52.8 G3D/$ ($150 MSRP vs $149 MSRP).

GeForce GTX 1650

2019

Why buy it

✅147.0% more average FPS across 50 tracked games in our benchmark data.
✅Costs $1 less on MSRP ($149 MSRP vs $150 MSRP).
✅Delivers 321.4% more G3D Mark for each dollar spent, at 52.8 vs 12.5 G3D/$ ($149 MSRP vs $150 MSRP).
✅300% more VRAM for high-resolution textures and newer games (4 GB vs 1 GB).
✅GeForce GTX 645 is already obsolete for modern gaming, so GeForce GTX 1650 is the less risky modern option long term.

Trade-offs

❌Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌55.8% longer card at 229mm vs 147mm.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 1650 is the faster gaming card right now. In our data, it leads by 147.0% in average FPS across 50 tracked games in our benchmark data and by 318.6% in PassMark G3D (7,869 vs 1,880), so the answer here is pretty clean.

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

GeForce GTX 1650 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 1 GB of VRAM, a 12nm process instead of 40nm, and a newer 2019 generation instead of 2010. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce GTX 1650 makes the most sense to buy today. It is $1 cheaper on MSRP at $149 vs $150, and it leads G3D-per-dollar by 321.4% (52.8 vs 12.5), so the value case lines up with the gaming result.
