Radeon R9 390X

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 21.6 vs 0 G3D/$ ($429 MSRP vs Unknown MSRP).
✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).

Trade-offs

❌Poor future-proofing: 2015-era hardware with 8 GB of VRAM is already a legacy-tier option for modern games.
❌358.3% higher power demand at 275W vs 60W.

RTX A1000 Mobile

2022

Why buy it

✅More future proof: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.
✅Draws 60W instead of 275W, a 215W reduction.
✅More future proof: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.

Trade-offs

Quick Answers

So, is RTX A1000 Mobile better than Radeon R9 390X?

Yes. RTX A1000 Mobile is clearly the better overall GPU here. You are also looking at 9,463 vs 9,278 in G3D Mark. On top of that, RTX A1000 Mobile is a 2022 card with no meaningful modern upscaling stack, while Radeon R9 390X is a 2015 model from an older generation with FSR upscaling. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

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

RTX A1000 Mobile is the more future-proof choice for 2026 and beyond. You are getting a newer 2022 generation instead of 2015, the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling, and a 8nm 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?

RTX A1000 Mobile is the smarter buy by a wide margin. RTX A1000 Mobile is priced in an unclear MSRP range at an unclear MSRP versus $429 MSRP, and you are getting 2.0% higher G3D Mark. Radeon R9 390X really only makes sense now as a very cheap stopgap or a used-market placeholder.

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

No, not for a fresh gaming build. Radeon R9 390X is 2015 hardware with 8 GB of VRAM, 9,278 in G3D Mark, and FSR upscaling. That is simply too far behind to be an easy modern recommendation.
