What is the meaning of Core i3

Core i3 (Chinese: core™ i3, Central code: Clarkdale) processor is Intel's first CPU+GPU product, built on Intel Westmere microarchitecture. Unlike Core i7, which supports three-channel storage, the core i3 only integrates dual-channel DDR3 memory controllers. In addition, the Core i3 integrates some of the North Bridge features that will integrate the Pci-express controller. The interface also differs from the LGA 1366 of the Core i7, with the core i3 adopting a new LGA 1156. Processor core, code-named Clarkdale, using the 32 nm process Core i3 has two cores, supporting hyper-Threading technology. L3 buffer storage, two core share 4MB. Core i3 was launched in early 2010.

Chipset, using the Intel P55,P53 (code: ibexpeak). In addition to supporting Lynnfield, it also supports Havendale processors. While the latter has only two processor cores, it integrates the display core. P55 is designed with a single chip and functions similar to the traditional South Bridge, supporting SLI and Crossfire technology. However, unlike the high-end X58 chipset, the P55 does not adopt newer QPI connections (because the I3 processor integrates PCI-E and memory controllers in the CPU, or with a QPI connection, except for the external use of DMI with a single chip P55 connection), using traditional DMI technology. interface, it can be compatible with other 5 series chipsets.

The core i3 can be viewed as a further compact version of the Core i5 and will have a 32nm process version (the core process is clarkdale and the architecture is Nehalem). The biggest feature of the core i3 is the integration of the GPU (graphics processor), which means that the core i3 will be encapsulated by the CPU+GPU two cores. Because of the limited performance of the integrated GPU, users want to get better 3D performance and can be added to the graphics card. It is worth noting that even if the core process is Clarkdale, the production process showing the core part will still be 45nm. Integration of CPUs and GPU, such plans both Intel and AMD early on, they all think that the integration platform is a trend in the future. And Intel is undoubtedly in the front, integrated GPU CPU has been introduced in 2010, commonly known as "core I", still for the core series.

Process characteristics

Intel's Lynnfield Core I5/i7, released in 09, has integrated the memory controller with the PCI-E controller to the CPU, in short, most of the previous motherboard bridge chipset features are integrated into the CPU, so the P55 motherboard chipset also has no North-south bridges, The CPU communicates with the P55 chip through the DMI bus. The h55/h57 motherboard is similar to the P55 motherboard, but H55/H57 also provides Intel flexible Display Interface (FDI) to output the GPU's signal output. Therefore, to adopt the Core i3 GPU features, you must match the h55/h57 motherboard, if used on the P55 motherboard, you can only use their CPU functions.

On the specs, Core i3 (that is, I3 530) of the CPU part of the dual-kernel design, through hyper-Threading technology to support four threads, bus frequency 2.5gt/s DMI bus, three-level cache from 8MB to 4MB, while memory controller, dual-channel, hyper-Threading technology and other technologies will be retained. Also using the LGA 1156 interface, the corresponding motherboard will be h55/h57.

February 2011, Inter company released four new core I series processors and six core new flagship i7-990x. These include the new I3, I3 2100. The new version of the I3--I3 2100 compared with the old I3, the main frequency increased to 3100, bus frequencies increased to 5.0gt/s, the multiplier increased to 31 times times, the most important is to adopt the latest and new I5, new I7 the same framework Sandy Bridge. However, the level three cache is reduced to 3M.

The

i3 CPU belongs to the midrange cpu,i5 positioning is high-end. Although I3 integrates the GPU, the performance is extremely limited. Mainly because I3 is a dual core four thread, commonly known as dual core, and the previous release does not integrate the GPU I5 750, is the original four core CPU, quad core in performance beyond the dual-core many. Don't think I5 is inferior to I3 because there is no integrated GPU, this is a misunderstanding.
