| Intel Core i5 microprocessor family, released in September 2009, is a family of processors with medium-level performance as compared to Core i7. The i5 processors include many features found in Core i7 Nehalem CPUs - single-die quad-core design, on-die DDR3 memory controller, point-to-point protocol used to communicate with I/O devices, 256 KB level 2 cache (per core), large shared level 3 cache, SSE4 instructions, and support for such features as Virtualization technology and Turbo Boost technology |
Some features, though, were crippled or completely removed in the Core i5 CPUs:- The microprocessors include dual-channel memory controller as opposed to triple-channel controller in Nehalem CPUs.
- Instead of Quick Path Interface, the i5 processors feature slower Direct Media Interface point-to-point protocol.
- i5-7xx processors do not support Hyper-Threading technology.
- Future i5-6xx microprocessors do include Hyper-Threading feature, but they have only two CPU cores.
Desktop Intel Core i5 microprocessors are packaged in 1156-land Land-Grid Array (LGA) package, and require socket 1156 motherboards.
