Radeon PRO W6400

2022

Why buy it

✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform 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

❌Poor future-proofing: 2017-era hardware with 8 GB of VRAM is already a legacy-tier option for modern games.
❌270% higher power demand at 185W vs 50W.
❌43.5% longer card at 241mm vs 168mm.

Quick Answers

So, is Radeon RX 580 better than Radeon PRO W6400?

Yes. Radeon RX 580 is clearly the better overall GPU here. Radeon RX 580 averages 59.9% more FPS across 50 tracked games in our benchmark data. You are also looking at 8,799 vs 8,428 in G3D Mark. On top of that, Radeon RX 580 is a 2017 card with FSR upscaling + limited Frame Generation, while Radeon PRO W6400 is a 2022 model from an older generation with FSR upscaling. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

Which one is more future-proof for 2026 and beyond?

Radeon PRO W6400 is the more future-proof choice for 2026 and beyond. You are getting a newer 2022 generation instead of 2017, the stronger feature stack with FSR upscaling instead of FSR upscaling + limited Frame Generation, and a 6nm process instead of 14nm. That broader feature stack should age better as more games lean on modern upscaling and frame-generation support.

Which one is the smarter buy today, not just the cheaper card?

Radeon RX 580 is the smarter buy by a wide margin. Radeon RX 580 is in basically the same MSRP band at $229 MSRP versus $229 MSRP, and you are getting 59.9% more estimated average FPS across 50 tracked games in our benchmark data and 4.4% higher G3D Mark. Radeon PRO W6400 really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does Radeon PRO W6400 make more sense than Radeon RX 580?

Yes. Radeon PRO W6400 is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is newer architecture, lower power draw (50W vs 185W), future-proofing, and staying closer to $229 MSRP more than squeezing out the extra headroom of Radeon RX 580. The trade-off is that Radeon RX 580 currently gives you 4.4% higher G3D Mark and 59.9% more estimated average FPS across 50 tracked games in our benchmark data. It only holds a slight 4.4% edge in G3D-per-dollar, so the value lead is real but narrow.
