Intel announced the Core i7 processors in August. Core i7 was formerly known as Nehalem. Tweaktown reviews the new Intel Core i7 platform launching today.
Quote from the review: "Today Intel’s CPU, formally known as Nehalem arrives and with it comes a new architecture along with a new bus. Intel’s latest addition to the Core architecture is the Core i7 series, which is based on the same architecture that made the Core 2 series so popular, but with a few major changes to the design. To replace the aging FSB, Intel has designed a new point-to-point communication protocol which is known as Quick Path Interconnect or QPI. Intel’s first generation of QPI is a 20-bit interface with bi-directional communication running at either 4.8GT/s for the Core i7 range or 6.4GT/s for the Core i7 Extreme range of processors."
