[inpai] World's First Review of HD6990 - Page 4

post #31 of 100
I find it really odd that it beats 2x 6970 CFX in a few cases. Have they only used a single CFX bridge for 2x 6970? Or is there something special about 6990's interconnect that we are missing?

Full load temps are OK, too. A pair of Caymans runs really hot when sandwitched together.

More than one cfx bridge does nothing special.

By "nothing special," you could even say, "nothing at all."

I remember when 5850 CFX was crashing at high resolutions in one of the reviews till AMD told them to use two bridges. Could be something similar here, too.

I personally think the 590 will top the 6990, but the 6990 will kill the 590 in price. I'd expect the 6990 to sell around $600 and no way will NVIDIA get even close to that seeing as the 580 is $500 right now.

In response to the question, "why can 580 beat 6990 at 3dmark11 performance setting and get trounced in extreme", it's likely because of memory bandwidth bottlenecking the 6990's 256 bit interface at the lower 720p res. Many reviews have show the 580 will win at lower resolutions while AMD's cards pull ahead at higher res.

I see. Not too many sites test at 3x30" resolutions though..

Let's hope that exchange rate doesn't hold true to MSRP here in the states. That would be way off what I was thinking it would cost.

WHy are you guys acting like the 6990 results are going to be magically better than Crossfired versions of whats out there. Obviously its going to be crossfired 6970's/6950's hybrid so the performance should already be obvious from benchmarks of those cards. I would personally stay away from these dual cards, Not worth it especially because AMD/Nvidia do not make custom drivers for them.
