i3 Nehalem microarchitecture based
The Core i3 was intended to be the new low end of the performance processor line from Intel, following the retirement of the Core 2 brand.
The first Core i3 processors were launched on January 7, 2010.
The first Nehalem based Core i3 was Clarkdale-based, with an integrated GPU and two cores. The same processor is also available as Core i5 and Pentium, with slightly different configurations.
The Core i3-3xxM processors are based on Arrandale, the mobile version of the Clarkdale desktop processor. They are similar to the Core i5-4xx series but running at lower clock speeds and without Turbo Boost.According to an Intel FAQ they do not support Error Correction Code (ECC) memory. According to motherboard manufacturer Supermicro, if a Core i3 processor is used with a server chipset platform such as Intel 3400/3420/3450, the CPU will support ECC with UDIMM. When asked, Intel confirmed that, although the Intel 5 series chipset supports non-ECC memory only with the Core i5 or i3 processors, using those processors on a motherboard with 3400 series chipsets it will support the ECC function of ECC memory.A limited number of motherboards by other companies also support ECC with Intel Core iX processors; the Asus P8B WS is an example, but it does not support ECC memory under Windows non-server operating systems.
Turbo Boost: Core i3 processors do not support "Turbo Boost"
performance.
Integrated GPU
(graphics processor): All models of Core i3 have an integrated GPU
CPU clock rate: 2.933 GHz to 3.2 GHz.
Launch date: January 7, 2010
Positioning: Low-end and Core 2,
i5 Nehalem microarchitecture based.
The first Core i5 using the Nehalem microarchitecture was introduced on September 8, 2009, as a mainstream variant of the earlier Core i7, the Lynnfield core. Lynnfield Core i5 processors have an 8 MB L3 cache, a DMI bus running at 2.5 GT/s and support for dual-channel DDR3-800/1066/1333 memory and have Hyper-threading disabled. The same processors with different sets of features (Hyper-Threading and other clock frequencies) enabled are sold as Core i7-8xx and Xeon 3400-series processors, which should not be confused with high-end Core i7-9xx and Xeon 3500-series processors based on Bloomfield.
The Core i5-5xx mobile processors are named Arrandale and based on the 32 nm Westmere shrink of the Nehalem microarchitecture. Arrandale processors have integrated graphics capability but only two processor cores. They were released in January 2010, together with Core i7-6xx and Core i3-3xx processors based on the same chip. The L3 cache in Core i5-5xx processors is reduced to 3 MB, while the Core i5-6xx will use the full cache and the Core i3-3xx will have no support for Turbo Boost.[29] Clarkdale, the desktop version of Arrandale, is sold as Core i5-6xx, along with related Core i3 and Pentium brands. It has Hyper-Threading enabled and the full 4 MB L3 cache.
According to Intel "Core i5 desktop processors and desktop boards typically do not support ECC memory",but information on limited ECC support in the Core i3 section also applies to Core i5 and i7.

i7 Nehalem microarchitecture based
Intel Core i7 is an Intel brand name for several families of desktop and laptop 64-bit x86-64 processors using the Nehalem, Westmere, Sandy Bridge and Ivy Bridge microarchitectures. The Core i7 brand is targeted at the business and high-end consumer markets for both desktop and laptop computers, and is distinguished from the Core i3 (entry-level consumer), Core i5 (mainstream consumer), and Xeon (server and workstation) brands.
The Core i7 name was introduced with the Bloomfield Quad-core processor in late 2008. In 2009 new Core i7 models based on the Lynnfield desktop quad-core processor and the Clarksfield quad-core mobile were added, and models based on the Arrandale dual-core mobile processor were added in January 2010. The first six-core processor in the Core lineup is the Gulftown, which was launched on March 16, 2010. Both the regular Core i7 and the Extreme Edition are advertised as five stars in the Intel Processor Rating. In January 2011, Intel released the second generation of Core i7 processors. Both the first and second generation of Intel Core i7 processors are rated as 5 stars in the Intel processor rating. The second generation of Intel core processors are based on the "Sandy Bridge" core and were updated in April 2012 with "Ivy Bridge".
In each of the first three microarchitecture generations of the brand, Core i7 has family members using two distinct system-level architectures, and therefore two distinct sockets (for example, LGA 1156 and LGA 1366 with Nehalem). In each generation, the highest-performing Core i7 processors use the same socket and QPI-based architecture as the low-end Xeon processors of that generation, while lower-performing Core i7 processors use the same socket and PCIe/DMI/FDI architecture as the Core i5.
"Core i7" is a successor to the Intel Core 2 brand. Intel representatives stated that the moniker Core i7 is meant to help consumers decide which processor to purchase as the newer Nehalem-based products are released in the future.

i3 Sandy Bridge microarchitecture based.
Released on January 20, 2011, the Core i3-2xxx line of desktop and mobile processors is a direct replacement of the 2010 "Clarkdale" Core i3-5xx and "Arrandale" Core i3-3xxM models, based on the new microarchitecture. While they require new sockets and chipsets, the user-visible features of the Core i3 are largely unchanged, including the lack of support for Turbo Boost and AES-NI. Unlike the Sandy Bridge based Celeron and Pentium processors, the Core i3 line does support the new Advanced Vector Extensions.
i5 Sandy Bridge microarchitecture based.
In January 2011, Intel released new quad-core Core i5 processors based on the "Sandy Bridge" microarchitecture at CES 2011. New dual-core mobile processors and desktop processors arrived in February 2011.
The Core i5-2xxx line of desktop processors are mostly quad-core chips, with the exception of the dual-core Core i5-2390T, and include integrated graphics, combining the key features of the earlier Core i5-6xx and Core i5-7xx lines. The suffix after the four-digit model number designates unlocked multiplier (K), low-power (S) and ultra-low-power (T).
The desktop CPUs now all have four non-SMT cores (like the i5-750), with the exception of the i5-2390T. The DMI bus is running at 5 GT/s.
The mobile Core i5-2xxxM processors are all dual-core chips like the previous Core i5-5xxM series and share most the features with that product line.
i7 Sandy Bridge microarchitecture based.
The Core i7 brand remains the high-end for Intel's desktop and mobile processors, featuring the Sandy Bridge models with the largest amount of L3 cache and the highest clock frequency. Most of these models are very similar to their smaller Core i5 siblings. The quad-core mobile Core i7-2xxxQM/XM processors follow the previous "Clarksfield" Core i7-xxxQM/XM processors, but now also include integrated graphics.
