Intel Core i5

Core i5 is a brand name used by Intel for several upcoming processors. It is positioned between the mid-range Core i3 and Core 2 and the high-end Core i7 and Xeon brands.

As of September 7, 2009, there is only one Core i5 processor: The Core i5 750,[1] which is a 2.66 GHz quad-core processor with Hyper-threading disabled. This appears to be a case of crippleware, as the other two speed grades of LGA 1156 processors introduced at the same time include Hyper-threading, but are Core i7 processors.

Lynnfield[2] is the codename of a family of Intel desktop and mobile x86-64 microprocessors, which were released on September 8, 2009[3] using the Intel Nehalem microarchitecture and Intel Westmere microarchitecture and are a mainstream variant to the Intel Core i7 family.

 Lynnfield microprocessors will feature an integrated dual-channel DDR3 memory controller,integrated PCI-Express graphics controller and Direct Media Interface controller for communication with Intel P55 and improved turbo boost (Ibexpeak) chipset.

Lynnfield was supposed to be released in July, 2009, but has been delayed to September because Intel wants vendors to deplete the Intel series 4 chipset so the processor can be released with the Intel series 5 chipsets. It has been stated among various sources that Core i5 would be the brand name for Lynnfield, but Intel announced at Computex 2009 that this was not the case, as both the Core i5 and Core i7 processors will use the Lynnfield core.
