2024

Why buy it

✅43.8% more average FPS across 14 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 40W, a 10W reduction.

Trade-offs

❌Lower G3D Mark per dollar, at 0 vs 21.8 G3D/$ (Unknown MSRP vs $170 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

Radeon 840M is the faster gaming card right now. In our data, it leads by 43.8% in average FPS across 14 tracked games in our benchmark data and by 2.8% in PassMark G3D (3,803 vs 3,698), so the answer here is pretty clean.

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

Radeon 840M 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 14nm, and a newer 2024 generation instead of 2018. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Quadro P620 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, Quadro P620 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 840M has the stronger long-term case.
