Radeon R9 390X

2015

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌Poor future-proofing: 2015-era hardware with 8 GB of VRAM is already a legacy-tier option for modern games.
❌
53.8% HIGHER MSRP
$429 MSRPvs$279 MSRP
❌Lower G3D Mark per dollar, at 21.6 vs 33.4 G3D/$ ($429 MSRP vs $279 MSRP).
❌57.1% higher power demand at 275W vs 175W.

Radeon RX 590

2018

Why buy it

✅Costs $150 less on MSRP ($279 MSRP vs $429 MSRP).
✅Delivers 54.4% more G3D Mark for each dollar spent, at 33.4 vs 21.6 G3D/$ ($279 MSRP vs $429 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅Less risky long-term buy than Radeon R9 390X: it remains the more sensible modern option while Radeon R9 390X is already legacy-tier future-proofing.
✅Draws 175W instead of 275W, a 100W reduction.

Trade-offs

❌Limited future-proofing: older hardware, 8 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.

Quick Answers

So, is Radeon RX 590 better than Radeon R9 390X?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 9,278 vs 9,315 in G3D Mark. The bigger reason to prefer Radeon RX 590 is the overall package: you are getting a newer generation, FSR upscaling + limited Frame Generation, plus much lower power draw (175W vs 275W).

Which one is more future-proof for 2026 and beyond?

Radeon RX 590 is the more future-proof choice for 2026 and beyond. You are getting a newer 2018 generation instead of 2015, better frame-generation support with FSR Frame Generation (2023) instead of FSR upscaling, and a 12nm process instead of 28nm. That broader feature stack should age better as more games lean on modern upscaling and frame-generation support.

Which one is the smarter buy today, not just the cheaper card?

Radeon RX 590 can still make sense if you find it at the right price, especially around $279 MSRP. Radeon RX 590 is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon RX 590 is about $150 cheaper on MSRP at $279 MSRP versus $429 MSRP, and you are getting 0.4% higher G3D Mark. Moving to $279 MSRP gets you newer hardware, lower power draw (175W vs 275W), and FSR upscaling + limited Frame Generation.

Is Radeon R9 390X still worth buying for gaming in 2026?

Yes. Radeon R9 390X is still a strong gaming card in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. Price is really the swing factor here. If you find it at or below $429 MSRP, it remains a very sensible buy. Radeon RX 590 is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR upscaling + limited Frame Generation.
