Rock from SUN - 16 cores/32 threads

    [http://en.wikipedia.org/wiki/Rock_(processor)]
    "The Rock processor implements the 64-bit SPARC V9 instruction set and the VIS 3.0 SIMD multimedia instruction set extension.Each Rock processor has 16 cores, with each core capable of running two threads simultaneously, yielding 32 threads per chip. Servers built with Rock use FB-DIMMs to increase reliability, speed and density of memory systems. The Rock processor uses a 65nm manufacturing process for a design frequency of 2.3 GHz.The maximum power consumption of the Rock processor chip is approximately 250W."

    Ко всему этому - это один из первых процессоров аппаратно поддерживающих Transactional Memory. А это одна из самых перспективных технологий для разработки баз данных, а Oracle купил SUN:)
    "In August 2007, Sun confirmed that Rock would be the first production processor to support transactional memory."
