GeForce GTX 670MX SLI vs Radeon 820M: 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 670MX SLI

2012

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌Lower average FPS than Radeon 820M across 33 tracked games in our benchmark data.
❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌400% higher power demand at 150W vs 30W.

Radeon 820M

2024

Why buy it

✅3.0% more average FPS across 33 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 150W, a 120W reduction.

Trade-offs

❌Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

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 3.0% in average FPS across 33 tracked games in our benchmark data and by 3.3% in PassMark G3D (2,143 vs 2,075), 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: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 4nm process instead of 28nm, and a newer 2024 generation instead of 2012. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon 820M makes the most sense today based on the pricing and value data we have for this matchup.
