GeForce GTX 645

2010

Why buy it

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

Trade-offs

❌Lower PassMark G3D performance (1,880 vs 7,869).
❌Less VRAM, with 1 GB vs 4 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2010-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌
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

✅+318.6% higher PassMark G3D performance.
✅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).
✅Less risky long-term buy than GeForce GTX 645: it remains the more sensible modern option while GeForce GTX 645 is already obsolete for modern gaming.

Trade-offs

❌Limited future-proofing: older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.
❌55.8% longer card at 229mm vs 147mm.

Quick Answers

So, is GeForce GTX 1650 better than GeForce GTX 645?

Yes. GeForce GTX 1650 is clearly the better overall GPU here. You are also looking at 7,869 vs 1,880 in G3D Mark. On top of that, GeForce GTX 1650 is a 2019 card with no meaningful modern upscaling stack, while GeForce GTX 645 is a 2010 model from an older generation with no meaningful modern upscaling stack. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

Which one is more future-proof for 2026 and beyond?

GeForce GTX 1650 is the more future-proof choice for 2026 and beyond. You are getting a newer 2019 generation instead of 2010, 318.6% more raw performance headroom, more VRAM at 4 GB instead of 1 GB, and a 12nm process instead of 40nm. That leaves it with more room for heavier textures, tougher ray tracing loads, and higher-end 1440p or 4K gaming over the next few years.

Which one is the smarter buy today, not just the cheaper card?

GeForce GTX 1650 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce GTX 1650 is about $1 cheaper on MSRP at $149 MSRP versus $150 MSRP, and you are getting 318.6% higher G3D Mark. It also leads G3D-per-dollar by 321.4%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is GeForce GTX 645 still worth buying for gaming in 2026?

Yes. GeForce GTX 645 is still a strong modern gaming GPU: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It remains a good buy when you can get it meaningfully cheaper than the alternative around $150 MSRP, even if GeForce GTX 1650 is still the cleaner recommendation on overall value today.
