About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, raw graphics performance, VRAM, feature set, power efficiency, pricing context, and long-term value so you can see which GPU actually makes more sense.

Radeon R9 390

2015

Why buy it

  • Costs $100 less on MSRP ($329 MSRP vs $429 MSRP).
  • Delivers 24.5% more G3D Mark for each dollar spent, at 26.9 vs 21.6 G3D/$ ($329 MSRP vs $429 MSRP).

Trade-offs

  • Poor future-proofing: 2015-era hardware with 8 GB of VRAM is already a legacy-tier option for modern games.

Quick Answers

So, is Radeon R9 390X better than Radeon R9 390?
Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 8,855 vs 9,278 in G3D Mark. The bigger reason to prefer Radeon R9 390X is the overall package: you are getting FSR upscaling.
Which one is more future-proof for 2026 and beyond?
Radeon R9 390 is the safer long-term GPU choice because it gives you the stronger overall hardware and feature outlook for modern games.
Which one is the smarter buy today, not just the cheaper card?
Radeon R9 390X is the smarter buy by a wide margin. Radeon R9 390X is about 30.4% more expensive on MSRP at $429 MSRP versus $329 MSRP, and you are getting 4.8% higher G3D Mark. Radeon R9 390 really only makes sense now as a very cheap stopgap or a used-market placeholder.
When does Radeon R9 390 make more sense than Radeon R9 390X?
Yes. Radeon R9 390 is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is future-proofing and staying closer to $329 MSRP more than squeezing out the extra headroom of Radeon R9 390X. The trade-off is that Radeon R9 390X currently gives you 4.8% higher G3D Mark. Radeon R9 390 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
