Radeon 820M vs Radeon R9 M385: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

Radeon 820M

2024

Why buy it

✅36.5% more average FPS across 30 tracked games in our benchmark data.
✅Better long-term bet: RDNA 3+ (2024) on 4nm gives it a newer hardware base for upcoming games.
✅Draws 30W instead of 75W, a 45W reduction.

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌Lower G3D Mark per dollar, at 0 vs 6.9 G3D/$ (Unknown MSRP vs $300 MSRP).

Radeon R9 M385

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 6.9 vs 0 G3D/$ ($300 MSRP vs Unknown MSRP).
✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).

Trade-offs

❌Lower average FPS than Radeon 820M across 30 tracked games in our benchmark data.
❌2015 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌150% higher power demand at 75W vs 30W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon 820M is the faster gaming card right now. In our data, it leads by 36.5% in average FPS across 30 tracked games in our benchmark data and by 4% in PassMark G3D (2,143 vs 2,061), so the answer here is pretty clean.

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

Radeon 820M is the safer long-term pick for 2026 and beyond. The case is simple: a 4nm process instead of 28nm and a newer 2024 generation instead of 2015. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon R9 M385 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 R9 M385 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 820M has the stronger long-term case.
