Intel is telling everyone who will listen that they are going back to rDIMMs in 2008 over about 90% of their server line. This is due to them not being able to hit power numbers, seemingly a problem with the tech itself vs implementations, and of course cost. Looking out at the numbers, 4S servers are about 10% of the server market, 2S make up most of the rest, so this would seem to indicate that FBDs will be relegated to high socket counts.More info over here.
This move actually makes complete sense, the benefits of FBDs, high capacity and high bandwidth are a good match for that market. Likewise, the down sides, high cost, power and latency are less of a problem there. I can also see them putting it in niche 2S servers that need lots of DIMMs but go easier on the CPUs.
Intel pulls back from FB-DIMMs
