GeForce 305M vs Radeon HD 3650 AGP: 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 305M

2015

Why buy it

✅6.6% more average FPS across 50 tracked games in our benchmark data.
✅Draws 33W instead of 45W, a 12W reduction.
✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

❌2015 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 0 vs 1.9 G3D/$ (Unknown MSRP vs $80 MSRP).

Radeon HD 3650 AGP

2011

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 1.9 vs 0 G3D/$ ($80 MSRP vs Unknown MSRP).

Trade-offs

❌Lower average FPS than GeForce 305M across 50 tracked games in our benchmark data.
❌2011 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?

GeForce 305M is the faster gaming card right now. In our data, it leads by 6.6% in average FPS across 50 tracked games in our benchmark data and by 0.7% in PassMark G3D (151 vs 150), so the answer here is pretty clean.

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

GeForce 305M is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2015 generation instead of 2011. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon HD 3650 AGP makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Radeon HD 3650 AGP is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 305M has the stronger long-term case.
