GeForce RTX 4070 vs Radeon HD 6670: 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

✅1161.4% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 513.7% more G3D Mark for each dollar spent, at 44.9 vs 7.3 G3D/$ ($599 MSRP vs $99 MSRP).
✅Access to a newer frame-generation stack with DLSS 3.5 + Frame Generation (2023).
✅500% more VRAM for high-resolution textures and newer games (12 GB vs 2 GB).
✅Better long-term bet: Ada Lovelace (2022−2024) on 5nm gives it a newer hardware base for upcoming games.

Trade-offs

❌81% longer card at 304mm vs 168mm.

Radeon HD 6670

2010

Why buy it

✅Costs $500 less on MSRP ($99 MSRP vs $599 MSRP).
✅Measures 168mm instead of 304mm, a 136mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than GeForce RTX 4070 across 50 tracked games in our benchmark data.
❌Less VRAM, with 2 GB vs 12 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like DLSS 3.5 + Frame Generation (2023).
❌2010 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 7.3 vs 44.9 G3D/$ ($99 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 1161.4% in average FPS across 50 tracked games in our benchmark data and by 3613% in PassMark G3D (26,919 vs 725), 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 2 GB of VRAM, native frame generation with DLSS 3.5 + Frame Generation (2023), while Radeon HD 6670 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 to buy today. It is $500 more expensive on MSRP at $599 vs $99, and it leads G3D-per-dollar by 513.7% (44.9 vs 7.3), so the value case lines up with the gaming result.
