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

Radeon Pro Vega 20

2018

Why buy it

✅6.4% 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).
❌2018 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 0 vs 88.7 G3D/$ (Unknown MSRP vs $60 MSRP).
❌185.7% higher power demand at 100W vs 35W.

Radeon RX 6300

2022

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 88.7 vs 0 G3D/$ ($60 MSRP vs Unknown 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 6nm gives it a newer hardware base for upcoming games.
✅Draws 35W instead of 100W, a 65W reduction.

Trade-offs

❌Lower average FPS than Radeon Pro Vega 20 across 50 tracked games in our benchmark data.

Quick Answers

Which GPU is faster for gaming right now?

Radeon Pro Vega 20 is the faster gaming card right now. In our data, it leads by 6.4% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon RX 6300 instead at 5,319 vs 5,169, 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 6300 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 20 has no comparable frame-generation support, a 6nm process instead of 14nm, and 12 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 6300 makes the most sense today based on the pricing and value data we have for this matchup. Radeon Pro Vega 20 still makes more sense if max raw gaming performance matters more than value.
