❌24100% longer card at 242mm vs 1mm.

Radeon HD 7620G + 8670M Dual

2013

Why buy it

✅Costs $349 less on MSRP ($150 MSRP vs $499 MSRP).
✅Draws 50W instead of 220W, a 170W reduction.
✅Measures 1mm instead of 242mm, a 241mm 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 512 MB vs 8 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on FSR Upscaling / FSR 4 (2025) instead.
❌2013 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 3.8 vs 44.4 G3D/$ ($150 MSRP vs $499 MSRP).

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 1404.3% in average FPS across 50 tracked games in our benchmark data and by 3742.6% in PassMark G3D (22,172 vs 577), 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 512 MB of VRAM, a 8nm process instead of 28nm, 46 vs 0 ray-tracing units, and a newer 2020 generation instead of 2013. 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 $349 more expensive on MSRP at $499 vs $150, and it leads G3D-per-dollar by 1055.1% (44.4 vs 3.8), so the value case lines up with the gaming result.
