See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GeForce GTX 660
2012Why buy it
- ✅Costs $370 less on MSRP ($229 MSRP vs $599 MSRP).
- ✅Draws 140W instead of 200W, a 60W reduction.
- ✅Measures 241mm instead of 304mm, a 63mm shorter card that is more SFF-friendly.
Trade-offs
- ❌Lower average FPS than GeForce RTX 4070 across 50 tracked games in our benchmark data.
- ❌Less VRAM, with 3 GB vs 12 GB for high-resolution textures and newer games.
- ❌No equivalent frame-generation stack like DLSS 3.5 + Frame Generation (2023).
- ❌2012 hardware with 3 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌Lower G3D Mark per dollar, at 17.6 vs 44.9 G3D/$ ($229 MSRP vs $599 MSRP).
GeForce RTX 4070
2023Why buy it
- ✅546.0% more average FPS across 50 tracked games in our benchmark data.
- ✅Delivers 154.7% more G3D Mark for each dollar spent, at 44.9 vs 17.6 G3D/$ ($599 MSRP vs $229 MSRP).
- ✅Access to a newer frame-generation stack with DLSS 3.5 + Frame Generation (2023).
- ✅300% more VRAM for high-resolution textures and newer games (12 GB vs 3 GB).
- ✅Better long-term bet: Ada Lovelace (2022−2024) on 5nm gives it a newer hardware base for upcoming games.
Trade-offs
- ❌42.9% higher power demand at 200W vs 140W.
- ❌26.1% longer card at 304mm vs 241mm.
