Radeon PRO W6400

2022

Why buy it

✅Costs $320 less on MSRP ($229 MSRP vs $549 MSRP).
✅Delivers 141.1% more G3D Mark for each dollar spent, at 36.8 vs 15.3 G3D/$ ($229 MSRP vs $549 MSRP).
✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.
✅Draws 50W instead of 275W, a 225W reduction.
✅Measures 168mm instead of 275mm, a 107mm shorter card that is more SFF-friendly.

Trade-offs

❌Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

Radeon R9 290X / 390X

2015

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌Poor future-proofing: 2015-era hardware with 4 GB of VRAM is already a legacy-tier option for modern games.

Quick Answers

So, is Radeon PRO W6400 better than Radeon R9 290X / 390X?

Yes. Radeon PRO W6400 is clearly the better overall GPU here. You are also looking at 8,428 vs 8,380 in G3D Mark. On top of that, Radeon PRO W6400 is a 2022 card with FSR upscaling, while Radeon R9 290X / 390X is a 2015 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 2015, 100.0% more ray-tracing hardware, and a 6nm process instead of 28nm. That makes it the safer long-run choice for modern games.

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

Radeon PRO W6400 can still make sense if you find it at the right price, especially around $229 MSRP. Radeon PRO W6400 is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon PRO W6400 is about $320 cheaper on MSRP at $229 MSRP versus $549 MSRP, and you are getting 0.6% higher G3D Mark. Moving to $229 MSRP gets you newer hardware, lower power draw (50W vs 275W), and FSR upscaling.

Is Radeon R9 290X / 390X still worth buying for gaming in 2026?

Yes. Radeon R9 290X / 390X is still a strong gaming card in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. Price is really the swing factor here. If you find it at or below $549 MSRP, it remains a very sensible buy. Radeon PRO W6400 is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR upscaling.
