Quick Answers

So, is Radeon Pro WX 5100 better than Radeon HD 7990?

Yes, but this is not really about a huge raw performance gap. Radeon Pro WX 5100 averages 16.6% more FPS across 50 tracked games in our benchmark data. The broader synthetic picture is also very close at 5,566 vs 5,500 in G3D Mark. The bigger reason to prefer Radeon Pro WX 5100 is the overall package: you are getting a newer generation, FSR upscaling, plus much lower power draw (75W vs 375W).

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

Radeon HD 7990 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 Pro WX 5100 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Radeon Pro WX 5100 is about $500 cheaper on MSRP at $499 MSRP versus $999 MSRP, and you are getting 16.6% more estimated average FPS across 50 tracked games in our benchmark data and a lower G3D Mark (5,500 vs 5,566). It also leads G3D-per-dollar by 97.8%. Radeon HD 7990 is the more forward-looking alternative, so it still has a real case if you care more about future-proofing than about squeezing out the strongest gaming value today.

When does Radeon HD 7990 make more sense than Radeon Pro WX 5100?

Yes. Radeon HD 7990 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 $999 MSRP more than squeezing out the extra headroom of Radeon Pro WX 5100. The trade-off is that Radeon Pro WX 5100 currently gives you a lower G3D Mark (5,500 vs 5,566) and 16.6% more estimated average FPS across 50 tracked games in our benchmark data. It also leads G3D-per-dollar by 97.8%.
