Generations of Intel Core Processor

Whenever you see the various ranges of Intel processors, you might notice a thing that Intel releases its series of processors in a generation-wise manner. Do you know what’s the fact behind this? As we all know that technology is improving and updating rapidly as time and days are passing through. So, whenever the improved or better technology has been implemented in the processors, Intel releases its processors with the new edition. This series of the new editions of processors are released by Intel in the form of a new generation. Basically, the sequence of releasing the processors in these generations starts after the commencement of Core i-series processors (i3, i5, i7, i9 CPUs).

However, the Generation of a CPU matters a lot in terms of performance and energy efficiency. For example, if we say that the i7 8th generation CPU is better than the i5 8th generation CPU then it is quite true. But if we say that the i7 8th generation CPU is better than the i5 9th generation CPU then this statement might be wrong. This is because these upgraded generation CPUs are better than the previous generation CPUs. In terms of previous generations, they are better in terms of process technology (nm technology) or micro-architecture which enhances its performance, high-end clock speed and power efficiency, etc. There are various generations of Intel processors.

Intel Core I series

6th Generation of Intel Core Processor- SkyLake

Intel release Skylake, the 6th Generation processor in August 2015. Skylake is just a new redesign on the same 14nm process technology which was initially introduced in Broadwell (Intel’s 5th generation architecture). This generation was launched in August 2015. According to Intel, its redesign makes a great difference in the increase in its CPU and GPU performance and low power consumption.

Its maximum clock speed reaches up to 4.5 GHz. The cache memory of this generation is the same as the previous generation for L1 and L2 cache but there is 2 MB per core of the L3 cache. This architecture supports 2-28 cores of CPUs. Skylake is the last microarchitecture that has official driver support by Microsoft for Operating systems older than Windows 10.

7th Generation of Intel Core Processor- KabyLake

The Micro-architecture of this Generation is known by Intel’s codename ‘Kaby Lake’ and was launched in August 2016. Kaby lake began to ship their Kaby lake chips for mobile OEMs in the Quarter phase of 2016 but Kaby Lake desktop chips were officially launched in January 2017. Kaby Lake is of course a refresh of Skylake architecture with few efficiencies and power optimizations. CPU Clock speed performance ranges from 1.00 GHz to 4.5 GHz. The number of cores ranges from 2-4 cores.

Kaby Lake is the first Intel platform which lacks the official driver support by Microsoft for Operating system older than Windows 10. Kaby Lake was designed to improve the performance in 3D graphics and 4K video playback. It supports 1151 LGA sockets and has dual-channel support for DDR3L-1600 and DDR4-2400 RAM slots. Its L1 and L2 cache is the same as previous generations and the L3 cache is up to 8 MB which is shared by all the cores of the CPU. Kaby Lake is the first computer architecture that enables overclocking feature for I3 branded CPU.

8th Generation of Intel Core Processor- KabyLake-R

In 2017, Intel redefined Kaby Lake processors as their new 8th Generation CPUs. The specifications are the same as mentioned in the 7th generation (Kaby Lake) Intel processor but 8th generation processors support DDR4 RAM up to 2666 MHz frequency but lack DDR3L RAM support.

9th Generation of Intel Core Processor- Coffee Lake

Intel’s brand new 9th Generation was launched in October 2017 but come in sale in early 2019. This generation was known by Coffee Lake name suggested by Intel on behalf of their microarchitecture(Coffee Lake). This is the first generation platform for the commencement of a brand new I9 processor which reaches up to 5 GHz of clock speed in its activated turbo boost technology.

This generation brings gaming PCs to the next level. Because Coffee Lake processors break the limit of 4 cores per CPU. Now the new processors support up to 8 cores per CPU. It supports 1151 LGA sockets with altered pinouts to support more than 4 cores along with up to 16 MB of L3 cache. Since there are more than 4 cores then definitely it will impart heat enormously. To manage it’s thermal, intel attached Integrated Heat Spreader (IHS) to their CPU instead of thermal paste which was used earlier in their previous generations.

10th Generation of Intel Core Processor- Cannon Lake/Ice Lake

Cannon Lake, Intel’s 10th Generation architecture, was introduced with all new 10 nm process technology. It was released in late 2017 but production properly started in 2018 and began its sale in early 2020. This generation was best in power efficiency due to its small build form factor of 10 nm and due to minimum production of heat then clock speed will also increase in this segment up to 5.3 GHz in its I9 unlocked high-end series processor. I9 10th gen Processor is the World’s fastest mobile processor segment.

Ice lake is the 2nd generation for the 10 nm CPUs.

They use BGA 1526 sockets and come with DDR4 RAM with 3200 MHz and LPDDR4X RAM with 3733 MHz frequency support. This is the first processor architecture by intel that comes with integrated support for Wi-Fi 6 (802.11ax) and Thunderbolt 3 USB port. This architecture is a boon for portable computing devices like laptops, mobiles, etc, because this architecture is most energy-efficient which releases less amount heat hence improves the performance by increasing clock speed and battery life.
