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

  • 2233.0% more average FPS across 50 tracked games in our benchmark data.
  • Delivers 100+% more G3D Mark for each dollar spent, at 44.9 vs 0 G3D/$ ($599 MSRP vs Unknown MSRP).
  • Access to a newer frame-generation stack with DLSS 3.5 + Frame Generation (2023).
  • 2300% more VRAM for high-resolution textures and newer games (12 GB vs 512 MB).
  • Better long-term bet: Ada Lovelace (2022−2024) on 5nm gives it a newer hardware base for upcoming games.

Trade-offs

  • 166.7% higher power demand at 200W vs 75W.

Radeon HD 6490M

2011

Why buy it

  • Draws 75W instead of 200W, a 125W reduction.

Trade-offs

  • Lower average FPS than GeForce RTX 4070 across 50 tracked games in our benchmark data.
  • Less VRAM, with 512 MB vs 12 GB for high-resolution textures and newer games.
  • No equivalent frame-generation stack like DLSS 3.5 + Frame Generation (2023).
  • 2011 hardware with 512 MB 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 44.9 G3D/$ (Unknown 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 2233.0% in average FPS across 50 tracked games in our benchmark data and by 7021.4% in PassMark G3D (26,919 vs 378), 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 512 MB of VRAM, native frame generation with DLSS 3.5 + Frame Generation (2023), while Radeon HD 6490M has no comparable frame-generation support, a 5nm process instead of 40nm, 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 4070 makes the most sense today based on the pricing and value data we have for this matchup.

Advanced Features (DLSS/FSR)

The clearest feature edge for the GeForce RTX 4070 is support for DLSS 3.5 + Frame Generation. In games that support it, that can smooth out motion and lift perceived FPS. The Radeon HD 6490M does not have comparable native support in the same tier.The GeForce RTX 4070 gets NVIDIA DLSS, which still tends to look cleaner in motion. The Radeon HD 6490M leans on FSR, which is flexible and widely supported, but usually a bit rougher at the same settings.
