GeForce RTX 4070 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 4070

2023

Why buy it

  • 675.8% more average FPS across 50 tracked games in our benchmark data.
  • Delivers 229% more G3D Mark for each dollar spent, at 44.9 vs 13.7 G3D/$ ($599 MSRP vs $159 MSRP).
  • 200% more VRAM for high-resolution textures and newer games (12 GB vs 4 GB).
  • Better long-term bet: Ada Lovelace (2022−2024) on 5nm gives it a newer hardware base for upcoming games.

Trade-offs

  • 300% higher power demand at 200W vs 50W.

Radeon RX 640

2019

Why buy it

  • Costs $440 less on MSRP ($159 MSRP vs $599 MSRP).
  • Draws 50W instead of 200W, a 150W reduction.

Trade-offs

  • Lower average FPS than GeForce RTX 4070 across 50 tracked games in our benchmark data.
  • Less VRAM, with 4 GB vs 12 GB for high-resolution textures and newer games.
  • 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 44.9 G3D/$ ($159 MSRP vs $599 MSRP).

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 675.8% in average FPS across 50 tracked games in our benchmark data and by 1139.4% in PassMark G3D (26,919 vs 2,172), 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 4 GB of VRAM, a 5nm process instead of 14nm, 46 vs 0 ray-tracing units, and a newer 2023 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 4070 makes the most sense to buy today. It is $440 more expensive on MSRP at $599 vs $159, and it leads G3D-per-dollar by 229% (44.9 vs 13.7), so the value case lines up with the gaming result.

Advanced Features (DLSS/FSR)

Both GPUs support Frame Generation, but they get there through different ecosystems. The GeForce RTX 4070 uses DLSS 3.5 + Frame Generation, while the Radeon RX 640 relies on FSR Frame Generation + AFMF. Both can help smooth out supported games, but they are not on the same feature stack.The GeForce RTX 4070 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.
