IBM and Intel today separately revealed a new chip process that should dramatically improve the performance of CPUs as soon as this year, according to Reuters. Called high-K metal gate, the technology replaces materials long used in chips until today, replacing the silicon of a given chip transistor's dielectric and gate with hafnium and other metals. The result is the ability to shrink chips from 65 to 45 nanometers with far less of electricity leaks that waste heat and performance. This has the potential not only to boost speed in the near-term but also for years ahead, both semiconductor makers said. Intel added to the announcement by demonstrating a faster Core 2 Duo processor using the 45nm process. Codenamed "Penryn," the new CPU (pictured) uses the extra space to boost the second-level cache per core by 50 percent, jumping from 4MB to 6MB. A new set of processor instructions dubbed SSE4 will also help with media decoding. Although Penryn is expected to arrive in production systems only towards the end of 2007, the processor has already been demonstrated running multiple operating systems -- including Mac OS X, the company said.
