Based of the Intel Skylake X micro architecture, this Core X processor lineup is oriented for HEDP (High-End Desktop) with options ranging from 8 to 18 cores for extreme performance. These processors are built using 14nm technology and support quad-channel memory. The Intel Turbo Boost Max Technology 3.0¹ identifies the processor's fastest two cores and directs your most critical workloads to them, to achieve optimized performance in lightly-threaded computing. Every product comes unlocked, enabling you to overclock beyond the maximum turbo frequency, while the solder thermal interface material (STIM) delivers efficient heat transfer between the CPU die and heat spreader, thus facilitating extreme overclocking.² These Core X processors come in LGA 2066 packaging and work with Intel X299-chipset motherboards. This Intel Core i9-9990X model has 10 cores (20 threads), support 44 PCIe 3.0 lanes, and features 3.50 GHz base frequency, 4.40 GHz turbo frequency, and 4.50 GHz maximum turbo frequency with Intel Turbo Boost Max 3.0 technology. It has NO built-in graphics so a discrete graphics card is required to complete your setup.
