Amd\'s latest Fusion chip, Llano, apparently has a weakness

[RSS_Poster]

An article posted on ars technica by Jon Stokes states that this hybrid chip suffers from a lack of memory bandwith limiting it's performance. "Llano, AMD's second entry in its Fusion family of processors that combine a CPU and GPU on the same die, launched earlier this month to moderately positive reviews.http://feeds.feedburner.com/~r/NewsAtBjorn3dcom/~4/p4QT1HeMS88

so you'll just have to throw in some high speed ram

I dont think that will help much however if you can get the base clock to 133 then that should help.

if you look at the architecture, there isn't much you can do. the bottleneck comes from the bandwidth between the cpu and gpu on the die.

[James86]

looks like memory speed does effect it

latency doesn't seem to have much effect tho

[Blacksmith1]

memory speed affects any CPU. the bottleneck referred to in that article is internal to the chip tho' and no external forces are going to relive it. O/Cing might seem to alleviate it, faster mem might hide it a bit, boosting the hypet transport might help the system go faster. but that bottleneck will still be there, and getting rid of it would make the system even faster in all the afore-mentioned cases.
