Things to know before picking the best ram for i7 8700K

About the Intel Core i7 8700K

Better known as Intel Coffee lake, the 8th generation series of processors were announced on September 25th, 2017. The Coffee lake series comes with enhanced performance and was the superior CPU family of its time. Instead of using thermal paste, Intel soldered the integrated Heat Spreader. This change in architecture assisted these CPU’s to have fewer thermal issues that may arise. This family of CPUs had increased cores since the 2011 range of CPU’s which is why this set was superior in its time.

The Coffee Lake CPUs were manufactured using Intel’s 14 nm process which added to the overall performance. The more advanced Coffee Lake Refresh (9th Gen) and the Ice Lake (10th Gen) CPUs have surfaced, this could be the reason the production of 8th Gen CPUs stopped. In 2021, the new Tiger Lake (11th generation) CPUs will be introduced. Coffee Lake CPUs are still capable of doing wonders as they have a maximum turbo frequency of 4.7GHz.
