GeForce GTX 775M vs Radeon 840M: 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 775M

2013

Why buy it

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

Trade-offs

❌Lower average FPS than Radeon 840M across 17 tracked games in our benchmark data.
❌2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌233.3% higher power demand at 100W vs 30W.

Radeon 840M

2024

Why buy it

✅8.6% more average FPS across 17 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 100W, a 70W 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 840M is the faster gaming card right now. In our data, it leads by 8.6% in average FPS across 17 tracked games in our benchmark data. PassMark G3D leans toward GeForce GTX 775M instead at 3,837 vs 3,803, so for this question the real-game FPS result matters more than the synthetic split.

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 28nm, and a newer 2024 generation instead of 2013. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon 840M makes the most sense today based on the pricing and value data we have for this matchup.
