About G3D Mark

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 6970M Crossfire

2011

Why buy it

  • Costs $849 less on MSRP ($150 MSRP vs $999 MSRP).
  • Delivers 574.5% more G3D Mark for each dollar spent, at 37.6 vs 5.6 G3D/$ ($150 MSRP vs $999 MSRP).
  • 33.3% more VRAM for high-resolution textures and newer games (4 GB vs 3 GB).
  • Draws 50W instead of 375W, a 325W reduction.
  • Measures 1mm instead of 305mm, a 304mm shorter card that is more SFF-friendly.

Trade-offs

  • Lower average FPS than Radeon HD 7990 across 50 tracked games in our benchmark data.
  • Very weak future-proofing: 2011-era hardware with 4 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.

Radeon HD 7990

2013

Why buy it

Quick Answers

So, is Radeon HD 7990 better than Radeon HD 6970M Crossfire?
Yes. Radeon HD 7990 is the better GPU overall here. You are getting 53.9% more average FPS across 50 tracked games in our benchmark data and 1.3% higher PassMark G3D performance. It also comes from 2013 instead of 2011, which helps its case as the more complete modern gaming card.
Which one is more future-proof for 2026 and beyond?
Radeon HD 6970M Crossfire is the more future-proof choice for 2026 and beyond. You are getting more VRAM at 4 GB instead of 3 GB. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.
Which one is the smarter buy today, not just the cheaper card?
Radeon HD 7990 is the smarter buy by a wide margin. Radeon HD 7990 is about 566.0% more expensive on MSRP at $999 MSRP versus $150 MSRP, and you are getting 53.9% more estimated average FPS across 50 tracked games in our benchmark data and a lower G3D Mark (5,566 vs 5,637). Radeon HD 6970M Crossfire really only makes sense now as a very cheap stopgap or a used-market placeholder.
When does Radeon HD 6970M Crossfire make more sense than Radeon HD 7990?
Yes. Radeon HD 6970M Crossfire 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 lower power draw (50W vs 375W), future-proofing, and staying closer to $150 MSRP more than squeezing out the extra headroom of Radeon HD 7990. The trade-off is that Radeon HD 7990 currently gives you a lower G3D Mark (5,566 vs 5,637) and 53.9% more estimated average FPS across 50 tracked games in our benchmark data. Radeon HD 6970M Crossfire still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
