Quick Answers

So, is Radeon HD 6990M Crossfire better than Radeon Ryzen 5 6600H?

Yes. Radeon HD 6990M Crossfire is clearly the better overall GPU here. You are also looking at 3,500 vs 3,448 in G3D Mark. On top of that, Radeon HD 6990M Crossfire is a 2011 card with FSR upscaling, while Radeon Ryzen 5 6600H is a 2021 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 Ryzen 5 6600H is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2011, 100.0% more ray-tracing hardware, and a 7nm process instead of 40nm. That makes it the safer long-run choice for modern games.

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

Radeon HD 6990M Crossfire is the smarter buy by a wide margin. Radeon HD 6990M Crossfire is about 99.7% more expensive on MSRP at $699 MSRP versus $350 MSRP, and you are getting 1.5% higher G3D Mark. Radeon Ryzen 5 6600H really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does Radeon Ryzen 5 6600H make more sense than Radeon HD 6990M Crossfire?

Yes. Radeon Ryzen 5 6600H 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 newer architecture, future-proofing, and staying closer to $350 MSRP more than squeezing out the extra headroom of Radeon HD 6990M Crossfire. The trade-off is that Radeon HD 6990M Crossfire currently gives you 1.5% higher G3D Mark. Radeon Ryzen 5 6600H still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
