GeForce GT 520 vs GeForce RTX 3070: 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 GT 520

2015

Why buy it

  • Costs $440 less on MSRP ($59 MSRP vs $499 MSRP).
  • Draws 90W instead of 220W, a 130W reduction.
  • Measures 145mm instead of 242mm, a 97mm shorter card that is more SFF-friendly.

Trade-offs

  • Lower average FPS than GeForce RTX 3070 across 50 tracked games in our benchmark data.
  • Less VRAM, with 2 GB vs 8 GB for high-resolution textures and newer games.
  • No DLSS support; it relies on Upscaling support instead.
  • 2015 hardware with 2 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 5.5 vs 44.4 G3D/$ ($59 MSRP vs $499 MSRP).

GeForce RTX 3070

2020

Why buy it

  • 2610.4% more average FPS across 50 tracked games in our benchmark data.
  • Delivers 711.6% more G3D Mark for each dollar spent, at 44.4 vs 5.5 G3D/$ ($499 MSRP vs $59 MSRP).
  • Access to DLSS 2 Super Resolution (2020).
  • 300% more VRAM for high-resolution textures and newer games (8 GB vs 2 GB).
  • Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

  • 144.4% higher power demand at 220W vs 90W.
  • 66.9% longer card at 242mm vs 145mm.

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 2610.4% in average FPS across 50 tracked games in our benchmark data and by 6764.4% in PassMark G3D (22,172 vs 323), 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 2 GB of VRAM, the newer upscaling stack, DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack, a 8nm process instead of 28nm, 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 $440 more expensive on MSRP at $499 vs $59, and it leads G3D-per-dollar by 711.6% (44.4 vs 5.5), so the value case lines up with the gaming result.
