Radeon R9 M390X

2015

Why buy it

✅Draws 75W instead of 165W, a 90W reduction.

Trade-offs

❌Lower PassMark G3D performance (3,895 vs 16,581).
❌Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌Very weak future-proofing: 2015-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌
104.5% HIGHER MSRP
$550 MSRPvs$269 MSRP

Radeon RX 7600

2023

Why buy it

✅+325.7% higher PassMark G3D performance.

Quick Answers

So, is Radeon RX 7600 better than Radeon R9 M390X?

Yes. Radeon RX 7600 is clearly the better overall GPU here. You are also looking at 16,581 vs 3,895 in G3D Mark. On top of that, Radeon RX 7600 is a 2023 card with FSR 3 + AFMF, while Radeon R9 M390X 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?

Radeon RX 7600 is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2015, 325.7% more raw performance headroom, more VRAM at 8 GB instead of 4 GB, and better frame-generation support with FSR Frame Generation + AFMF (2023) instead of FSR upscaling. That leaves it with more room for heavier textures, tougher ray tracing loads, and higher-end 1440p or 4K gaming over the next few years.

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

Radeon RX 7600 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Radeon RX 7600 is about $281 cheaper on MSRP at $269 MSRP versus $550 MSRP, and you are getting 325.7% higher G3D Mark. It also leads G3D-per-dollar by 770.4%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is Radeon R9 M390X still worth buying for gaming in 2026?

Yes. Radeon R9 M390X is still a strong modern gaming GPU: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It remains a good buy when you can get it meaningfully cheaper than the alternative around $550 MSRP, even if Radeon RX 7600 is still the cleaner recommendation on overall value today.
