Even more info : 17GBs per link and 50ns latency.See here : http://bt.pa.msu.edu/TM/BocaRaton2006/talks/davis.pdf
Alsowe have Gesher compared to Larrabee : the L3 latency looks huge IMO ,maybe they are sharing the L3 for 2-4 cores and there is a shared L4behind all.
The latency for CSI seems high too , Numalink 4 (arguably the best interconnect on the market ) has 28ns , altough lowerBW ( 3.2GBs per direction )
Could it be that CSI BW to be 17GBs per direction ? Also is it bidirectional or not ?

今天又看了一下P大放的幻灯片,看到里边提到的CSI的典型延迟时间是50nm,同现在的延迟相比,确实小得多啊 w00t) |
