Quadro K4000M 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.

Quadro K4000M

2012

Why buy it

✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).

Trade-offs

❌Lower average FPS than Radeon 820M across 32 tracked games in our benchmark data.
❌2012 hardware with 4 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 820M

2024

Why buy it

✅13.6% more average FPS across 32 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

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.

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 13.6% in average FPS across 32 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: 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.
