Intel continues filling out its processor lineup with the introduction of the 2010 Intel Core Processor Family, comprising new versions of Core i3, Core i5, and Core i7 processors. The new Core i3 and Core i5 processors use Intel's new "Westmere" architecture, which brings facets of Intel's "Nehalem" design to the lower-end desktop CPUs (code-named "Clarkdale") and mobile CPUs (code-named "Arrandale"). These are Intel's first CPUs to be built on a 32-nanometer process, and some models include another first for Intel: a graphics processing unit (GPU) included on-chip. Built with Intel Hyper-Threading Technology and an improved version of the Turbo Boost feature introduced with the original Nehalem processors, how do these new dual-core CPUs compare with other processors in Intel's line? Benchmark Reviews tests the Intel Core i5-661 CPU, model BX80616I5661, with its integrated GPU to find out.
