Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 4070 is the faster gaming card right now. In our data, it leads by 19124.0% in average FPS across 50 tracked games in our benchmark data and by 538280% in PassMark G3D (26,919 vs 5), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce RTX 4070 is the safer long-term pick for 2026 and beyond. The case is simple: 12 GB vs 65 MB of VRAM, the newer feature stack, with DLSS 3.5 Super Resolution (2023) and DLSS 3.5 + Frame Generation (2023), while GeForce4 MX 420 is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 5nm process instead of 12nm, and 46 vs 0 ray-tracing units. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce RTX 4070 makes the most sense to buy today. It is $500 more expensive on MSRP at $599 vs $99, and it leads G3D-per-dollar by 88881% (44.9 vs 0.1), so the value case lines up with the gaming result.
