IBM Introduces World's Fastest Processor: 5.2GHz Enterprise Chip

               The new zEnterprise technology is the result of an investment of more than $1.5 billion in IBM research and development in the zEnterprise line, as well as more than three years of collaboration with some of IBM's top clients around the world. If you're into details, the z196 processor is a four-core chip that contains 1.4 billion transistors on a 512-square millimeter (mm) surface. It's manufactured using IBM's 45 nanometer (nm) SOI processor technology, and it makes use of IBM's patented embedded DRAM (eDRAM) technology, which allows IBM to place dense DRAM caches, or components, on the same chips as high-speed microprocessors, resulting in improved performance.

               The core server in the zEnterprise System -- called zEnterprise 196 -- contains 96 of the world's fastest, most powerful microprocessors, capable of executing more than 50 billion instructions per second. That's roughly 17,000 times more instructions than the Model 91, the high-end of IBM's popular System/360 family, could execute in 1970.
