A lot of little Phi coprocessors lightens the load

The Xeon Phi is not Larrabee but it does give a chance to remind people that Intel did at one time swear we would be seeing huge results from a lot of strung together Pentium chips.  Nor is Many Integrated Cores the same as AMD's Magny-cours, although you can be forgiven if that thought popped into your head.  Instead the Xeon Phi is a co-processor that will have 50 or more 512-bit SIMD architecture based processors, each with 512KB of Level 2 cache.  These cores are comparatively slow on their own but have been designed to spread tasks over dozens of cores for parallel processing to make up for the lack of individual power.  Intel sees Phi as a way to create HPC servers which will be physically smaller than one based solely on traditional Xeon based servers as well as being more efficient.  There is still a lot more we need to learn about these chips; until then you can check out The Inquirer's article on Intel's answer to NVIDIA and AMD's HPC cards.

Can't be bothered clicking the link.

I'm not sure on any exact figures, but you can expect it to be really expensive at it's aimed at enterprise/HPC market :).
