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 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
                                                            Intel Core I series

1st Generation of Intel Core Processor- Nehalem

The First Generation of Intel CPUs is based on Nehalem micro-architecture. It is released by intel in 2008. This microarchitecture is based on 45nm process technology. These processors have 731M to 2300 Million transistors of size 45nm each. In the performance section, the clock speed of first Generation Intel processors ranges from 1.06 GHz to 3.33 GHz. Nehalem series has a minimum of 2 cores and a maximum of 6 cores.

The cache memory of these processors has 64 kb per core of L1 cache, 256 kb per core of L2cache, and 4 MB to 24 MB of shared (used by all the cores) L3 cache. Hyper-Threading technology was also reintroduced in this generation. It supports 1156 LGA sockets and 2-channel DDR3 RAM.

2nd Generation of Intel Core Processor- Sandy Bridge

2nd Generation Intel of processors was based on Sandy Bridge micro-architecture. It is introduced by Intel in 2011. Processors of this generation are based on 32 nm process technology.

Kaby Lake is the first computer architecture that enables overclocking features for I3 branded CPUs.

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.
