GeForce GT 820M vs Radeon 6600M: 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 GT 820M

2014

Why buy it

✅16.8% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌2014 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌150% higher power demand at 100W vs 40W.

Radeon 6600M

2023

Why buy it

✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 40W instead of 100W, a 60W reduction.
✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than GeForce GT 820M across 50 tracked games in our benchmark data.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GT 820M is the faster gaming card right now. In our data, it leads by 16.8% in average FPS across 50 tracked games in our benchmark data and by 1.1% in PassMark G3D (542 vs 536), so the answer here is pretty clean.

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

Radeon 6600M is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 6nm process instead of 28nm, 6 vs 0 ray-tracing units, and a newer 2023 generation instead of 2014. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce GT 820M 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, GeForce GT 820M is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 6600M has the stronger long-term case.
