The first rumour is that Blackford would lack performance. It seems to be true that there are performance problems with certain configurations but these are not chipset related and as this chipset will be released by late Q1 there's still enough time to get it right.
Another rumour is that they will be delayed, possible by as much as six months. This isn't entirely true but it is true that Blackford and Bensley were delayed from late February to early or mid March.
>br> The last one is about FB-DIMMs which are rumoured to be quite hot:
It seems that the buffer chips on the DIMMs were running much hotter than anticipated. The numbers I heard were 5-7W versus the expected 2-4W. There were some minor changes to the chips and tweaking here and there since the reports, and it is now mostly a non problem, hopefully. They may be a little above the hoped for 4W cap, but not by much, hopefully.The reporter believes Intel will be able to deliver a new, fast platform to get back into the server game.
