GRID P40-1Q 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.

GRID P40-1Q

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 1.3 vs 0 G3D/$ ($3,000 MSRP vs Unknown MSRP).

Trade-offs

❌2015 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌650% higher power demand at 225W vs 30W.

Radeon 840M

2024

Why buy it

✅Better long-term bet: RDNA 3+ (2024) on 4nm gives it a newer hardware base for upcoming games.
✅Draws 30W instead of 225W, a 195W reduction.
✅More future proof: RDNA 3+ (2024) on 4nm with a newer platform for upcoming games.

Trade-offs

❌Lower G3D Mark per dollar, at 0 vs 1.3 G3D/$ (Unknown MSRP vs $3,000 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

GRID P40-1Q is the faster gaming card right now based on the synthetic data we have. It leads by 0.9% in PassMark G3D (3,839 vs 3,803), which is the best performance signal available in this matchup.

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 2015. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

GRID P40-1Q 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, GRID P40-1Q is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 840M has the stronger long-term case.
