Best Intel Core-X Processors for Gaming & Work [LGA 2066 Socket]

Intel Core-X Processors are the latest edition to the Intel Core series processors. These Skylake-X and Kaby Lake–X processors and are based on LGA Socket 2066 and are launched to counter the AMD Ryzen 7 and AMD Ryzen 5 processors which are latest high-end  and mid-range processors from AMD respectively. Intel Core X-series Processors include Intel Core i9-7900X, Intel Core i9-7920X,  Intel Core i7-7820X, Intel Core i7-7800X, Intel Core i7-7740X and Intel Core i5-7640X.  We may see more variants of Intel Core-X series processors in future. These LGA 2066 Socket processors  require a Socket 2066 motherboard.

Skylake-X and Kaby Lake-X processors are an upgrade over the Broadwell-E processors. Intel Core Extreme processors require LGA 2011-v3 Socket motherboard but these newer Core-X series processors are totally different and is based on the latest LGA 2066 Socket. These CPUs or processors are very powerful and are a great choice for building a high-end gaming PC or a powerful workstation. Here in this post I am going to list down the latest Intel Core-X processors with their specifications and performance comparison.  

Note: Intel Core-X series processors do not come with integrated graphics and you have a buy a separate graphics card for it.

Final Words

Intel Core-X Processors are definitely the future of high-end Intel processors. This is also because of the newer LGA 2066 Socket X299 chipset is better has more potential and it may make the older LGA 1151 Socket obsolete in near future. This may also take a while too because the newer Intel 8th Generation processors (Coffee Lake) are also based on the LGA 1151 Socket. As of now, Core i9 is the fastest commercial processor but things will change very quickly after the introduction of Ryzen Threadripper processors from AMD, namely Ryzen Threadripper 1950X (16 Cores) and Ryzen Threadripper 1920X (12 Cores).
