The Nehalem architecture has numerous advantages over the Core 2 architecture. The Core i3 is based off a new architecture called Nehalem. The Core and Core 2 architectures were arguably Intel’s most successful architectures, as they replaced the Pentium 4 processors in desktop systems and made Intel competitive in that space once again. The Core 2 Duo processors are based off the Core 2 architecture.
However, the processors are based on different architectures. Both are dual-core processors and most Core 2 Duos and Core i3 have similar clock speeds. It is very similar to the Core 2 Duo in many ways. However, there is a newcomer which is challenging the Core 2 Duo. Core 2 Duo processors have also been the go-to for many less expensive desktop systems, with speeds reaching over 3Ghz. Over those three years the average speeds of Core 2 Duo processors have advanced significantly, and many of today’s Core 2 Duo laptops have speeds of around 2.2Ghz or faster. The Core 2 Duo has been the processor of choice in laptops for about three years.
