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

GeForce RTX 3060

2021

Why buy it

  • +1072.1% higher PassMark G3D performance.
  • Delivers 100+% more G3D Mark for each dollar spent, at 51.7 vs 0 G3D/$ ($329 MSRP vs Unknown MSRP).
  • Access to DLSS 2 Super Resolution (2020).
  • 100+% more VRAM for high-resolution textures and newer games (12 GB vs Unknown).
  • Better long-term bet: Ampere on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

  • 1033.3% higher power demand at 170W vs 15W.

Iris Plus Graphics 645

2019

Why buy it

  • Draws 15W instead of 170W, a 155W reduction.

Trade-offs

  • Lower PassMark G3D performance (1,450 vs 16,995).
  • Less VRAM, with Unknown vs 12 GB for high-resolution textures and newer games.
  • No DLSS support; it relies on Upscaling support instead.
  • 2019 hardware with Unknown 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 0 vs 51.7 G3D/$ (Unknown MSRP vs $329 MSRP).

Quick Answers

Which GPU is faster for gaming right now?
GeForce RTX 3060 is the faster gaming card right now based on the synthetic data we have. It leads by 1072.1% in PassMark G3D (16,995 vs 1,450), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce RTX 3060 is the safer long-term pick for 2026 and beyond. The case is simple: 12 GB vs Unknown of VRAM, the newer upscaling stack, DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack, a 8nm process instead of 14nm, and 28 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 3060 makes the most sense today based on the pricing and value data we have for this matchup.
