Difference between 6th and 7th generation

Intel has managed to retain the TDP at 15W by reducing the base clock of these processors. All these processors are of the 15W TDP type (though TDP is configurable by the OEM) and, unlike their previous 7th generation counterparts, they now feature quad cores with hyperthreading. The first of the 8th generation CPUs, the Kaby Lake-R was unveiled on August 21 with the launch of the Core i5-8250U, Core i5-8350U, Core i7-8550U and Core i7-8650U. Intel's processor nomenclature can be somewhat bewildering for those uninitiated and the new generation takes this confusion a notch up further: The 8th generation Intel CPUs will have a refreshed Kaby Lake lineup called the Kaby Lake-R (14nm+), which includes the 15W U-processor family, Coffee Lake (14nm++), which is purported to include the K-processor family from 65W to to 95W TDP, and Canon Lake (10nm). However, unlike earlier where each generation brought with it an underlying architectural or lithography change, the new 8th generation CPUs will be an assortment of multiple micro-architectures. In the midst of all these developments, Intel has announced the next iteration of its CPUs - the 8th generation Cores. Even in the server segment, AMD's EPYC and Intel's Skylake-SP are all set to bring high-end computing to datacenters worldwide.

There has been a lot of buzz in the High End Desktop (HEDT) segment as well, both with AMD unleashing the Threadripper 1950X with a massive 16-core/32-thread configuration and Intel revealing the Skylake-X ( Core i9-7900X) and Kaby Lake-X ( Core i7-7740X) CPUs in a variety of SKUs. AMD, after a longer than usual pause, demoed its Zen-architecture based Ryzen chips starting with the flagship Ryzen 7 1800X, which was received very well by both consumers and the press for its good price-to-performance ratio. The Intel 7th generation Kaby Lake platform debuted in late 2016 (with wide availability in early 2017) and has since been the staple of many laptops and desktops. 2017 has been a great year for CPU releases so far.
