Firstly, I want to introduce 2 processors named, Core 2 and core i5, then I will go in detail of the core 2 duo and core i5. Core 2 processor is very much older than the Core i5 processor core 2 processor was introduced in 2006 and the Core i5 processor was introduced in 2009. Intelligent people who buildup processors are still made Core i5 processors, they don’t make core 2 processors anymore. Core 2 Duo processors as show in name, are dual-core processors. The quad-core processors are also available from core 2 generation are called core 2 quads. Both names of processors are quite similar so that is so confusing. The Core i5 processors are much fast, enhance and updated processors. These are available in quad-core models, but the current generation Core i5 is quad-core processors.

Core 2 Duo Processors

The core 2 duo processors were launched in 2006. This is dual core processors. It has 64-bit dual-core processors, which is shown that two processors are worked inside a core 2 in parallel. Core 2 processors are available in notebook and desktop. These are based on the same processor. The notebook processor has a lower voltage than the desktop voltage.

Performance of Core 2 Duo Processors

The performance of the Core 2 Duo processor is very good as we compare it with its competitor the AMD Turion. The core duo processors can beat the competitor with the same clock rate.

Specifications of Core 2 Duo Processors

The core 2 duo processors are buildup in 65 nm, which contains 14 stages pipeline and 2-4 MB level 2. Each core is based on the Pentium m microarchitecture.

Core I5 Processor

Core i5 processors have launched bt intel in 2009. Core i5 is a computer processor which is available as a dual-core and quad-core processor. It is available in both desktop and laptop computers. There are three types of Core i5 processors and one of these types is ‘I’ series, which is called intel core processors. There are three types of intel core i5 processors.1.The intel core i5 6600k 3.50 GHz Quad-Core Skylake desktop processor,2.The intel core i5 6500 3.20 GHz quad-core Skylake desktop processors.3.The intel core i5 7500 this is the 7th generation, desktop processors.

Performance of Core I5 Processor

Core i5 was designed by Intel, has 64-bit x86 processors, in both desktop and laptop are available. Core i5 microprocessors are positioned between the high-end performance core i7 and low-end performance core i5. Core i5 is mid-range performance processors with performance higher than those offered by the core i7. core i5 has more core than i3 and have more features.


Intel has been grouping core i5 processors into 8 generations on the base of microarchitecture.

Core I5 1st generation

Westmere microarchitecture, the Arrandale based i5 processors are dual-core processors. These processors had the FSB replaced with direct media interface 1.0. These processors use socket g1.

Core I5 2nd generation

Core i5 2nd generation core i5 processors were based on the sandy bridge. It provides higher performance at higher power efficiency.

Core I5 3rd generation

Core I5 3rd generation of Core i5 processors, based on 22 nm processors for desktop and server. It was introduced in 2011. This is first microprocessors to use tri-gate transistors for their product.

Core I5 4th generation

Core  I5 4th generation of Core i5 is based on a 22nm process for mobile and desktop.it was introduced in 2013, became the successor to previous generation processors.

Core I5 5th generation

Core I5 5th generation of Core i5 is based on a 14nm process for mobile and desktop.it was introduced in early 2015, this is a process shrink of Haswell.

Core I5 6th generation

Intel introduced the desktop Skylake mid-range processors in 2015. All desktop models utilize the LGA-1151 socket which is used for most of the skyline desktop lineup.

Core I5 7th generation

The 7th generation of Core i5 was introduced in early 2017, are manufactured on Intel was improved 14nm process which allowed higher clock speed at similar voltage.

Core I5 8th generation

The 8th generation of core i5 was introduced in 2017. Those new microprocessors bring some considerable performance. Those new mobile core i5 also have hyperthreading enabled.
