See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GeForce 945M
2015Why buy it
- ✅Competitive enough if your priority is price, power, or specific feature preference.
Trade-offs
- ❌Lower average FPS than Radeon 820M across 31 tracked games in our benchmark data.
- ❌Less VRAM, with 512 MB vs 2 GB for high-resolution textures and newer games.
- ❌2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌150% higher power demand at 75W vs 30W.
Radeon 820M
2024Why buy it
- ✅35.8% more average FPS across 31 tracked games in our benchmark data.
- ✅300% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).
- ✅Better long-term bet: RDNA 3+ (2024) on 4nm gives it a newer hardware base for upcoming games.
- ✅Draws 30W instead of 75W, a 45W reduction.
Trade-offs
- ❌Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.
