50 cores! I thought Sun's Niagara chip was crazy... With Intel pushing even more cores now Concurrent programming paradigms are going to continue to grow in importance.
Sadly, I doubt Sunoracle will be able to top that with a 16-core Niagara III running 16 threads per core. In the meantime, Niagara II is shipping and this Intel piece is vaporware.
I would also like to remind the more overly enthusiastic (me included) that this family seems heavily targeted towards scientific (read FP-heavy) computing and I would expect more x86-controlled/GPU-based solutions in that space in the future. Niagara is more of a general-purpose animal targeted towards web and database workloads.
