GeForce RTX 3070 vs Radeon RX 640: 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

  • 639.4% more average FPS across 50 tracked games in our benchmark data.
  • Delivers 225.3% more G3D Mark for each dollar spent, at 44.4 vs 13.7 G3D/$ ($499 MSRP vs $159 MSRP).
  • Access to DLSS 2 Super Resolution (2020).
  • 100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).
  • Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

  • No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
  • 340% higher power demand at 220W vs 50W.

Radeon RX 640

2019

Why buy it

  • Costs $340 less on MSRP ($159 MSRP vs $499 MSRP).
  • Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
  • Draws 50W instead of 220W, a 170W reduction.

Trade-offs

  • Lower average FPS than GeForce RTX 3070 across 50 tracked games in our benchmark data.
  • Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
  • No DLSS support; it relies on FSR 3 (2023) instead.
  • Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
  • Lower G3D Mark per dollar, at 13.7 vs 44.4 G3D/$ ($159 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 639.4% in average FPS across 50 tracked games in our benchmark data and by 920.8% in PassMark G3D (22,172 vs 2,172), 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 4 GB of VRAM, a 8nm process instead of 14nm, 46 vs 0 ray-tracing units, and a newer 2020 generation instead of 2019. 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 $340 more expensive on MSRP at $499 vs $159, and it leads G3D-per-dollar by 225.3% (44.4 vs 13.7), so the value case lines up with the gaming result.

Advanced Features (DLSS/FSR)

The clearest feature edge for the Radeon RX 640 is support for FSR Frame Generation + AFMF. In games that support it, that can smooth out motion and lift perceived FPS. The GeForce RTX 3070 does not have comparable native support in the same tier.The GeForce RTX 3070 gets NVIDIA DLSS, which still tends to look cleaner in motion. The Radeon RX 640 leans on FSR, which is flexible and widely supported, but usually a bit rougher at the same settings.
