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 the 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 the 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 are 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.

Best Budget Intel Core-X Processors for Gaming and Workstation

Here are some of the best budget HEDT Intel Core-X series processors that pack a lot of power and are a great choice for building a VR Gaming PC or a powerful Workstation.

Intel Core i9-7900X Processor

Intel Core i9-7900X is one of the fastest processors available in the market today. This is a Skylake-X series processor and is one of the latest offerings from Intel. It is the cheapest Core i9 CPU and is even faster than the AMD Ryzen 7 1800X which is the top of range Ryzen 7 processor from AMD.  


Intel Core i9-7900X is a Deca-core (10 cores) processor and it comes with 13.75MB cache. The processor has got a base frequency of 3.30 GHz and Maximum Turbo Frequency of 4.30 GHz. Beyond Turbo Frequency, this Core i9 processor can also achieve speed up to 4.50 GHz using the latest Intel Turbo Boost Max Technology 3.0. This technology is almost similar to the AMD Ryzen Extended Frequency Range (XFR) where the processor can achieve higher turbo frequencies if there is sufficient cooling and power available at its disposal.

The processor comes with 10 physical cores but can execute 20 threads at once and can provide you performance equivalent to 20 core processor in multi-threaded applications. This is a great processor but it is more expensive and has higher power consumption compared to Ryzen 7 1800X.  The maximum memory supported by this Core i9 processor is up to 128GB (DDR4-2666). So if you don’t have any budget issues and want an ultra-fast processor for your monstrous gaming rig or powerful workstation then you should definitely go for this.

Final Words

Intel Core-X Processors are definitely the future of high-end Intel processors. This is also because 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).
