The New Intel® Core™ X-series Processor Family – Featuring the Intel® Core™ i9 Extreme Edition Processor


Extreme Platform for Gaming and Content Creation

May 30, 2017 — Creating rich, immersive experiences and bringing them to life takes a lot of compute power. Creators, gamers and enthusiasts have an insatiable demand for more power, more performance and more capability that lets them focus on what they want to do, not on whether their computer is up to the task. Intel is committed to continue giving them that extreme platform.

Introducing the new Intel® Core™ X-series processor family: Intel’s most scalable, accessible and powerful desktop platform ever. Ranging from 4 to 18 cores, it offers unprecedented scalability. With price points to match, there is an Intel® Core™ X-series processor that is sure to meet the needs for the widest range of enthusiast customers ever.


We’re also introducing the entirely new Intel® Core™ i9 processor brand, representing the highest performance for advanced gaming, VR and content creation. At the top of the lineup is the new Intel® Core™ i9 Extreme Edition processor – the first consumer desktop CPU with 18 cores and 36 threads of power.


Select SKUs of the Intel® Core™ X-series processor family brings extreme performance to enthusiasts with Intel® Turbo Boost Max Technology 3.0 creating new levels of single-threaded and dual-threaded performance. The Intel® Core™ X-series processor family also delivers the first teraflop desktop CPU from Intel. And install Intel® Optane™ memory, a smart system accelerator to improve system responsiveness with large storage drives. Intel® Core™ X-series processors use more cores and more threads to do more simultaneous workloads, like extreme mega-tasking. For our enthusiasts, we have new overclocking features including AVX 512 ratio offset, memory controller trim voltage control, and PEG/DMI overclocking to get more performance than ever before.
