Radeon Pro Vega 64

2017

Why buy it

✅2.1% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌Less VRAM, with Unknown vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌2017 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
49.8% HIGHER MSRP
$599 MSRPvs$400 MSRP
❌Lower G3D Mark per dollar, at 21.5 vs 32.5 G3D/$ ($599 MSRP vs $400 MSRP).

Radeon RX 6600S

2022

Why buy it

✅Costs $199 less on MSRP ($400 MSRP vs $599 MSRP).
✅Delivers 51.2% more G3D Mark for each dollar spent, at 32.5 vs 21.5 G3D/$ ($400 MSRP vs $599 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
✅100+% more VRAM for high-resolution textures and newer games (4 GB vs Unknown).
✅Better long-term bet: RDNA 2.0 (2020−2025) on 7nm gives it a newer hardware base for upcoming games.

Quick Answers

Which GPU is faster for gaming right now?

Radeon Pro Vega 64 is the faster gaming card right now. In our data, it leads by 2.1% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon RX 6600S instead at 13,016 vs 12,891, so for this question the real-game FPS result matters more than the synthetic split.

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

Radeon RX 6600S is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs Unknown of VRAM, native frame generation with FSR Frame Generation + AFMF (2023), while Radeon Pro Vega 64 has no comparable frame-generation support, a 7nm process instead of 14nm, and 28 vs 0 ray-tracing units. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 6600S makes the most sense to buy today. It is $199 cheaper on MSRP at $400 vs $599, and it leads G3D-per-dollar by 51.2% (32.5 vs 21.5), which is enough to swing the recommendation its way. Radeon Pro Vega 64 still makes more sense if max raw gaming performance matters more than value.
