Intel Core i5 microprocessor family, planned to be 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), 8 MB 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 processors do not support Hyper-Threading technology.
Intel Core i5 microprocessors are packaged in 1156-land Land-Grid
Array (LGA) package, and require socket 1156 motherboards.
