Verdict
AMD Radeon R9 390X wins in 10 out of 10 games
At CheckFPS we measured both cards across 10 popular games at 1080p, 1440p and 4K on a reference CPU. The R9 390X comes out ahead by around 11% more FPS on average, and that lead holds up as resolution climbs. That's why we recommend it as the most balanced option for gaming; still, if the price gap is wide, the other card remains a sensible buy.
Frequently asked questions
Common questions when comparing the R9 390X with the R9 390.
Which is better, the R9 390X or the R9 390?
On average at 1080p, the R9 390X is 11% faster than the R9 390. The best one for you depends on your resolution, budget and whether you prioritise ray tracing or price.
Which is better at 4K?
At 4K Ultra, the R9 390X averages 5 FPS and the R9 390 5 FPS across the most popular games. For smooth 4K, enabling upscaling (DLSS/FSR) helps on both.
Is it worth paying more for the faster one?
At 1080p or 1440p the FPS gap may not justify the extra cost; at 4K or with ray tracing the faster card matters more. Check the by-resolution table to decide.
Which has better ray tracing and upscaling?
AI upscaling (DLSS on NVIDIA, FSR on AMD, XeSS on Intel) raises FPS on both; for ray tracing, GeForce RTX cards usually lead. See each card’s support above.
How big is the FPS difference between them?
On average across top games, the gap is around 11% at 1080p. At higher resolutions (1440p and 4K) the relative difference usually stays similar.
R9 390X vs R9 390: what's the real difference?
In performance, the R9 390X beats the R9 390 by around 11% more FPS on average at 1080p — the gap shifts a bit by resolution, as shown in the table above. If you're torn between the R9 390X and the R9 390 on price, the price and $/FPS section above can help you decide.
