Intel gives 'turbo' boost to Nehalem

After politics, place the ads produced. In his keynote, Pat Gelsinger, current vice president of Intel company, has devoted much of his time in Nehalem, the new Intel architecture that will make his first steps with the Core processors i7 (see The successor of the Core 2 Duo Core will be the i7). Pat Gelsinger first indicated that the first i7 Core processors will arrive well in the market at year-end. While the characteristics of the Nehalem architecture have already been widely discussed, to start with four hearts on a monolithic design enjoying each HyperThreading technology, integration of a memory controller DDR3 on three channels, using a new bus system, the QPI, or the addition of 4.2 SSE instructions.



Intel today lifted the veil on the features in terms of energy management processor said. While Intel processors benefit all of the current clock gating, the Core i7 inaugurate the Power Gating, a name that implies a change in the manufacturing process. The idea is to effectively extinguish anything that might be, and each one of hearts, independently, all with a minimum leakage current between transistors. Côté operating frequencies, each heart has its own frequency modulation and voltage and Intel will function with Nehalem Turbo Mode appeared on Penryn processors for laptops. When an application does not use all hearts, hearts are turned off unused and frequency of the first two hearts increases automatically. By default this increase corresponds to a predetermined ratio will it be possible to modify the Core i7 Extreme processors, although this parameter is also dependent on the TDP processor.
