What level of processor does i5 belong to?
i5 processors belong to the mid-to-high-end level, with i3 and Pentium series at the lower end, and i7 and i9 series at the upper end. The i5 processor can meet most applications. As long as the machine performance is not very demanding, i5 is basically enough.

The Core i5 processor is a product of Intel and is also based on the Intel Nehalem microarchitecture. Unlike Core i7 which supports three-channel memory, Core i5 will only integrate dual-channel DDR3 memory controller. In addition, Core i5 will integrate some northbridge functions and will integrate PCI-Express controller. The interface is also different from the LGA 1366 of the Core i7. The Core i5 uses the new LGA 1156.
In terms of processor core, the Core i5, codenamed Lynnfiled and using a 45-nanometer process, will have four cores, does not support hyper-threading technology, and only provides a total of 4 threads. In terms of L2 buffer memory, each core has its own independent 256KB and shares an L3 buffer memory of 8MB. In terms of chipset, Intel P55 (codename: IbexPeak) will be used. In addition to supporting Lynnfield, it will also support Havendale processors. Although the latter has only two processor cores, it integrates a display core. The P55 will use a single-chip design with similar functions to the traditional south bridge and support SLI and Crossfire technology. However, unlike the high-end X58 chipset, the P55 will not use the newer QPI connection, but will use traditional DMI technology. In terms of interface, it is compatible with other 5 series chipsets. It will replace the P45 chipset.
Core i5 processor was produced in July 2009, shipped in August, and officially released on September 1.
In January 2011, Intel released a new generation of quad-core Core i5. The difference from the old model is that the new generation of Core i5 uses the Sandy Bridge architecture. In February of the same year, a dual-core version of Core i5 was released, and the interface was also updated to LGA 1155, which was incompatible with the old model. In addition to the first four digits in the code, the meanings of the last English words added are: K=unlocked multiplier version, S=low-power version, T=ultra-low-power version.
