What is Core i5

Core i5 (Chinese: core™ i5, Central Code: Lynnfield) The processor is an Intel product that is a low-level version of Intel Core i7, and is also based on the Intel Nehalem microarchitecture. Unlike Core i7, which supports three-channel storage, the core i5 only integrates dual-channel DDR3 memory controllers. In addition, the Core i5 will integrate some of the North Bridge features and will integrate the Pci-express controller. The interface also differs from the LGA 1366 of the Core i7, with the Core i5 adopting a new LGA 1156. Processor core, code-named Lynnfiled, with 45 nm process Core i5 will have four cores, does not support hyper-Threading technology, a total of only 4 threads. L2 buffer memory, each core has its own independent 256KB, and share a 8MB of L3 buffer memory.

Chipset, Intel P55 (code: Ibexpeak) will be used. In addition to supporting Lynnfield, it also supports Havendale processors. While the latter has only two processor cores, it integrates the display core. The P55 will be designed with a single chip, similar in function to the traditional South Bridge, supporting SLI and Crossfire technology. However, unlike the high-end X58 chipset, P55 does not use a newer QPI connection, but uses traditional DMI technology. interface, it can be compatible with other 5 series chipsets. It will replace the P45 chipset.

Core i5 processor with July 2009 production, August shipments, officially released on September 1.

In January 2011, Intel published a new generation of four core i5, unlike the old one, where a new generation of Core i5 switched to the Sandy Bridge architecture. In February, the dual-core version of Core i5 was released, and the interface was also updated to LGA 1155, which was incompatible with the old paragraph. In addition to the first four digits in the code, the last addition of the meaning of the English word is: k=-frequency version, s= low-power version, t= Ultra Low power version.

Core i5 in post processing preprocessing, increased support for sharpness functions and XVYCC operations, output support for two sets of independent HDMI high-definition output, and append 12Bit Color Depth. For sound effects, it adds Dolby True HD and DTS-HD Master audio output support to cater to HTPC HD application needs. New core i5-661 internal fully integrated GPU and North Bridge function is not even the top Core i7 can not match.
