By Marina Lopes NEW YORK (Reuters) – International Business Machines Corp, in its latest attempt at reviving demand for its hardware products, is launching high-end system servers that it says are 50 times faster than its closest competitor at analyzing data. The POWER8 servers, the product of a $2.4 billion, three-year investment, are part of the companys decade-long shift to higher-value hardware technology. IBM said the machines are 50 times faster than the low-end x86-based servers it sold to Chinese PC maker Lenovo Group Ltd in January. For IBM customers in particular the POWER8 represents a generational jump forward so far as overall performance and system capacity goes, said Charles King, an analyst at Pund-IT in California.
