GeForce RTX 3070 vs Radeon RX 580 2048SP: 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 3070

2020

Why buy it

✅106.6% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 33.3% more G3D Mark for each dollar spent, at 44.4 vs 33.3 G3D/$ ($499 MSRP vs $229 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.

Trade-offs

❌Less VRAM, with 8 GB vs 16 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌46.7% higher power demand at 220W vs 150W.

Radeon RX 580 2048SP

2018

Why buy it

✅Costs $270 less on MSRP ($229 MSRP vs $499 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅100% more VRAM for high-resolution textures and newer games (16 GB vs 8 GB).
✅Draws 150W instead of 220W, a 70W reduction.
✅Measures 241mm instead of 242mm, a 1mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than GeForce RTX 3070 across 50 tracked games in our benchmark data.
❌No DLSS support; it relies on FSR Upscaling / FSR 4 (2025) instead.
❌Older hardware, 16 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌Lower G3D Mark per dollar, at 33.3 vs 44.4 G3D/$ ($229 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 106.6% in average FPS across 50 tracked games in our benchmark data and by 190.5% in PassMark G3D (22,172 vs 7,633), 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: a 8nm process instead of 14nm, 46 vs 0 ray-tracing units, and a newer 2020 generation instead of 2018. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce RTX 3070 makes the most sense to buy today. It is $270 more expensive on MSRP at $499 vs $229, and it leads G3D-per-dollar by 33.3% (44.4 vs 33.3), so the value case lines up with the gaming result.
