2, i7 computers are generally suitable for designers.

3. Core i7 is a family logo of CPU produced by Intel for middle and high-end users, including Bloomfield(28), Lynnfield(29), Clarksfield(29), Arlanda Le (21), Gulftown(21) and Sandy Bridge(211).

4. Core i5 processor is a product of Intel, which is also based on Intel Nehalem microarchitecture. Unlike Core i7, which supports three channels of memory, Core i5 only integrates dual-channel DDR3 memory controllers. In addition, Core i5 will integrate some functions of Northbridge, and will integrate PCI-Express controller. The interface is also different from LGA 1366 of Core i7, and Core i5 adopts a brand-new LGA 1156. As for the processor core, the code name is Lynnfiled, and the Core i5 with 45nm process will have four cores, which does not support hyper-threading technology, and only four threads are provided in total. L2 buffer memory, each core has its own independent 256KB, and * * * enjoys an L3 buffer memory of 8MB. As for the chipset, Intel P55 (code name: IbexPeak) will be adopted. In addition to supporting Lynnfield, it will also support Havendale processor. Although the latter has only two processor cores, it integrates the display core. P55 will adopt a single-chip design, and its function is similar to that of the traditional south bridge, and it supports SLI and Crossfire technologies. However, unlike the high-end X58 chipset, P55 will not use the newer QPI connection, but will use the traditional DMI technology. Interface, it can be compatible with other 5 series chipsets. It will replace P45 chipset.
