Radeon Pro Vega 64

2017

Why buy it

✅Costs $100 less on MSRP ($599 MSRP vs $699 MSRP).
✅Delivers 14.7% more G3D Mark for each dollar spent, at 21.5 vs 18.8 G3D/$ ($599 MSRP vs $699 MSRP).

Trade-offs

❌Less VRAM, with Unknown vs 8 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2017-era hardware with Unknown of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌108.3% higher power demand at 250W vs 120W.
❌10.8% longer card at 267mm vs 241mm.

Radeon PRO W6600X

2021

Why buy it

✅100+% more VRAM for high-resolution textures and newer games (8 GB vs Unknown).

Quick Answers

So, is Radeon PRO W6600X better than Radeon Pro Vega 64?

Yes. Radeon PRO W6600X is clearly the better overall GPU here. You are also looking at 13,113 vs 12,891 in G3D Mark. On top of that, Radeon PRO W6600X is a 2021 card with FSR upscaling, while Radeon Pro Vega 64 is a 2017 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 W6600X is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2017, more VRAM at 8 GB instead of Unknown, 100.0% more ray-tracing hardware, and a 7nm process instead of 14nm. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.

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

Radeon PRO W6600X is the smarter buy by a wide margin. Radeon PRO W6600X is about 16.7% more expensive on MSRP at $699 MSRP versus $599 MSRP, and you are getting 1.7% higher G3D Mark. Radeon Pro Vega 64 really only makes sense now as a very cheap stopgap or a used-market placeholder.

Is Radeon Pro Vega 64 still worth buying for gaming in 2026?

No, not for a fresh gaming build. Radeon Pro Vega 64 is 2017 hardware with Unknown of VRAM, 12,891 in G3D Mark, and FSR upscaling. That is simply too far behind to be an easy modern recommendation.
