Intel Core i3 processor families
Core i3 line of entry-level Core-branded microprocessors was introduced on January 7, 2010 at Consumer Electronics Show in Las Vegas. Performance-wise and price-wise these are middle-class CPUs, positioned between more expensive and more powerful Core i5 and Core i7 microprocessors, and budget Pentium and Celeron processor families. Originally based on Westmere (enhanced Nehalem) micro-architecture, Core i3 CPUs were eventually transitioned to Sandy Bridge, and later to Ivy Bridge architecture. Common features of all Core i3 generations are dual-channel DDR3 memory controller, HD-capable graphics controller, and separate DMI interface to peripheral devices. All processors have per-core 256 KB level 2 cache, large level 3 cache shared between two cores, as well as support for basic and some advanced microarchitecture features, such as SSE4 instructions, and Virtualization and HyperThreading technologies. Sandy Bridge and Ivy Bridge CPUs also added support for Advanced Vector Extensions. As common with entry-level and budget families, Core i3 line doesn't include advanced technologies, or have some of its features crippled:
Intel Core i3 lineup currently consists of desktop and mobile Core i3 families. Desktop Core i3 microprocessors are packaged in 1155- and 1156-land Land-Grid Array (LGA) packages, and require socket 1155 or socket 1156 motherboards. Mobile Core i3 CPUs are manufactured in 1023-ball BGA, 1288-ball BGA or 988 micro-PGA packages. BGA processors are soldered directly on motherboards, and PGA processors utilize socket G1 or G2.
