ATI Radeon HD 4000 Series discussion

[Calmatory]

R700 having a much better interconnect between GPU's than with 2 separate cards allready gives the R700 a performance advantage over Crossfired 4870's with matching clocks.....therfore annihilat0r is correct that with a 5% clock increase on R700 could very well have a 15% performance gain over 2 4870's in crossfire.

in theary thats: Sideport comunication=10% gain over xfire
5% higher clockspeed=5% gain
=15%

Ah, so it was about R700 vs. 2x RV770XT? I thought he was talking about general 5% -> 15% improvement.

My bad
