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

Radeon PRO W6600X

2021

Why buy it

✅30.9% more average FPS across 50 tracked games in our benchmark data.
✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).

Trade-offs

❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌Radeon RX 6600S is the safer long-term pick here because the hardware is newer and the feature stack is stronger.
❌
74.8% HIGHER MSRP
$699 MSRPvs$400 MSRP
❌Lower G3D Mark per dollar, at 18.8 vs 32.5 G3D/$ ($699 MSRP vs $400 MSRP).
❌50% higher power demand at 120W vs 80W.

Radeon RX 6600S

2022

Why buy it

✅Costs $299 less on MSRP ($400 MSRP vs $699 MSRP).
✅Delivers 73.5% more G3D Mark for each dollar spent, at 32.5 vs 18.8 G3D/$ ($400 MSRP vs $699 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
✅Better long-term bet: RDNA 2.0 (2020−2025) on 7nm gives it a newer hardware base for upcoming games.
✅Draws 80W instead of 120W, a 40W reduction.

Trade-offs

❌Lower average FPS than Radeon PRO W6600X across 50 tracked games in our benchmark data.

Quick Answers

Which GPU is faster for gaming right now?

Radeon PRO W6600X is the faster gaming card right now. In our data, it leads by 30.9% in average FPS across 50 tracked games in our benchmark data and by 0.7% in PassMark G3D (13,113 vs 13,016), so the answer here is pretty clean.

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: native frame generation with FSR Frame Generation + AFMF (2023), while Radeon PRO W6600X has no comparable frame-generation support and a newer 2022 generation instead of 2021. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon RX 6600S makes the most sense to buy today. It is $299 cheaper on MSRP at $400 vs $699, and it leads G3D-per-dollar by 73.5% (32.5 vs 18.8), which is enough to swing the recommendation its way. Radeon PRO W6600X still makes more sense if max raw gaming performance matters more than value.
