GeForce RTX 3070 vs GeForce4 MX 420: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce RTX 3070

2020

Why buy it

  • 18222.0% more average FPS across 50 tracked games in our benchmark data.
  • Delivers 87877.1% more G3D Mark for each dollar spent, at 44.4 vs 0.1 G3D/$ ($499 MSRP vs $99 MSRP).
  • Access to DLSS 2 Super Resolution (2020).
  • 12598.4% more VRAM for high-resolution textures and newer games (8 GB vs 65 MB).
  • Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

  • 780% higher power demand at 220W vs 25W.

GeForce4 MX 420

2020

Why buy it

  • Costs $400 less on MSRP ($99 MSRP vs $499 MSRP).
  • Draws 25W instead of 220W, a 195W reduction.

Trade-offs

  • Lower average FPS than GeForce RTX 3070 across 50 tracked games in our benchmark data.
  • Less VRAM, with 65 MB vs 8 GB for high-resolution textures and newer games.
  • No DLSS support; it relies on Upscaling support instead.
  • 2020 hardware with 65 MB of VRAM already sits in legacy territory for modern games.
  • Lower G3D Mark per dollar, at 0.1 vs 44.4 G3D/$ ($99 MSRP vs $499 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
GeForce RTX 3070 is the faster gaming card right now. In our data, it leads by 18222.0% in average FPS across 50 tracked games in our benchmark data and by 443340% in PassMark G3D (22,172 vs 5), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce RTX 3070 is the safer long-term pick for 2026 and beyond. The case is simple: 8 GB vs 65 MB of VRAM, the newer upscaling stack, DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack, a 8nm 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 3070 makes the most sense to buy today. It is $400 more expensive on MSRP at $499 vs $99, and it leads G3D-per-dollar by 87877.1% (44.4 vs 0.1), so the value case lines up with the gaming result.
