✅Costs $51 less on MSRP ($499 MSRP vs $550 MSRP).
✅Delivers 527.4% more G3D Mark for each dollar spent, at 44.4 vs 7.1 G3D/$ ($499 MSRP vs $550 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅100% more VRAM for high-resolution textures and newer games (8 GB vs 4 GB).

Trade-offs

❌193.3% higher power demand at 220W vs 75W.

Radeon R9 M390X

2015

Why buy it

✅Draws 75W instead of 220W, a 145W reduction.

Trade-offs

❌Lower PassMark G3D performance (3,895 vs 22,172).
❌Less VRAM, with 4 GB vs 8 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on FSR Upscaling / FSR 4 (2025) instead.
❌Very weak future-proofing: 2015-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.

Quick Answers

So, is GeForce RTX 3070 better than Radeon R9 M390X?

Yes. GeForce RTX 3070 is clearly the better overall GPU here. You are also looking at 22,172 vs 3,895 in G3D Mark. On top of that, GeForce RTX 3070 is a 2020 card with DLSS Super Resolution, 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?

GeForce RTX 3070 is the more future-proof choice for 2026 and beyond. You are getting a newer 2020 generation instead of 2015, 469.2% more raw performance headroom, more VRAM at 8 GB instead of 4 GB, and the stronger feature stack with DLSS Super Resolution 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?

GeForce RTX 3070 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce RTX 3070 is about $51 cheaper on MSRP at $499 MSRP versus $550 MSRP, and you are getting 469.2% higher G3D Mark. It also leads G3D-per-dollar by 527.4%. 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 GeForce RTX 3070 is still the cleaner recommendation on overall value today.
