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

Radeon PRO W6400

2022

Why buy it

✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 50W instead of 185W, a 135W reduction.
✅Measures 168mm instead of 241mm, a 73mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower average FPS than Radeon RX 580 across 50 tracked games in our benchmark data.
❌Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation (2023).

Radeon RX 580

2017

Why buy it

✅59.9% more average FPS across 50 tracked games in our benchmark data.
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).

Trade-offs

❌2017 hardware with 8 GB of VRAM already sits in legacy territory for modern games.
❌270% higher power demand at 185W vs 50W.
❌43.5% longer card at 241mm vs 168mm.

Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 580 is the faster gaming card right now. In our data, it leads by 59.9% in average FPS across 50 tracked games in our benchmark data and by 4.4% in PassMark G3D (8,799 vs 8,428), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon PRO W6400 is the safer long-term pick for 2026 and beyond. The case is simple: a 6nm process instead of 14nm, 12 vs 0 ray-tracing units, and a newer 2022 generation instead of 2017. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon RX 580 makes the most sense to buy today. It is priced the same on MSRP at $229 vs $229, and it leads G3D-per-dollar by 4.4% (38.4 vs 36.8), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Radeon RX 580 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon PRO W6400 has the stronger long-term case.
