G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, raw graphics performance, VRAM, feature set, power efficiency, pricing context, and long-term value so you can see which GPU actually makes more sense.

Radeon HD 7790

2013

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 20.7 vs 0 G3D/$ ($149 MSRP vs Unknown MSRP).

Trade-offs

❌Very weak future-proofing: 2013-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.

Radeon Pro 555

2017

Why buy it

✅More future proof: GCN 4.0 (2016−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Very weak future-proofing: 2017-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌Lower G3D Mark per dollar, at 0 vs 20.7 G3D/$ (Unknown MSRP vs $149 MSRP).

Quick Answers

So, is Radeon Pro 555 better than Radeon HD 7790?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 3,090 vs 3,141 in G3D Mark. The bigger reason to prefer Radeon Pro 555 is the overall package: you are getting a newer generation, FSR upscaling.

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

Radeon HD 7790 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 555 is the smarter buy by a wide margin. Radeon Pro 555 is priced in an unclear MSRP range at an unclear MSRP versus $149 MSRP, and you are getting 1.7% higher G3D Mark. Radeon HD 7790 really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does Radeon HD 7790 make more sense than Radeon Pro 555?

Yes. Radeon HD 7790 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 $149 MSRP more than squeezing out the extra headroom of Radeon Pro 555. The trade-off is that Radeon Pro 555 currently gives you 1.7% higher G3D Mark. Radeon HD 7790 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
