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

Radeon R9 390X

2015

Why buy it

✅18.0% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 21.6 vs 0 G3D/$ ($429 MSRP vs Unknown MSRP).
✅33.3% more VRAM for high-resolution textures and newer games (8 GB vs 6 GB).

Trade-offs

❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌2015 hardware with 8 GB of VRAM already sits in legacy territory for modern games.
❌83.3% higher power demand at 275W vs 150W.

Radeon RX 5600M

2020

Why buy it

✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅Better long-term bet: RDNA 1.0 (2019−2020) on 7nm gives it a newer hardware base for upcoming games.
✅Draws 150W instead of 275W, a 125W reduction.

Trade-offs

❌Lower average FPS than Radeon R9 390X across 50 tracked games in our benchmark data.
❌Less VRAM, with 6 GB vs 8 GB for high-resolution textures and newer games.
❌Lower G3D Mark per dollar, at 0 vs 21.6 G3D/$ (Unknown MSRP vs $429 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

Radeon R9 390X is the faster gaming card right now. In our data, it leads by 18.0% in average FPS across 50 tracked games in our benchmark data and by 4.8% in PassMark G3D (9,278 vs 8,857), so the answer here is pretty clean.

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

Radeon RX 5600M is the safer long-term pick for 2026 and beyond. The case is simple: native frame generation with FSR Frame Generation (2023), while Radeon R9 390X has no comparable frame-generation support, a 7nm process instead of 28nm, and a newer 2020 generation instead of 2015. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon R9 390X makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Radeon R9 390X is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon RX 5600M has the stronger long-term case.
