See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GeForce GTX 870M
2014Why buy it
- ✅Draws 100W instead of 220W, a 120W reduction.
Trade-offs
- ❌Lower average FPS than GeForce RTX 3070 across 50 tracked games in our benchmark data.
- ❌Less VRAM, with 6 GB vs 8 GB for high-resolution textures and newer games.
- ❌No DLSS support; it relies on Upscaling support instead.
- ❌2014 hardware with 6 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌Lower G3D Mark per dollar, at 0 vs 44.4 G3D/$ (Unknown MSRP vs $499 MSRP).
GeForce RTX 3070
2020Why buy it
- ✅348.0% more average FPS across 50 tracked games in our benchmark data.
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 44.4 vs 0 G3D/$ ($499 MSRP vs Unknown MSRP).
- ✅Access to DLSS 2 Super Resolution (2020).
- ✅33.3% more VRAM for high-resolution textures and newer games (8 GB vs 6 GB).
- ✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.
Trade-offs
- ❌120% higher power demand at 220W vs 100W.
