Intel's limited edition 5GHz Core i7-8086K CPU on sale

Intel celebrates its 50th anniversary and the 40th anniversary of x86 processor architecture by releasing the Core i7-8086K CPU, which is named after the first x86 processor, the 8086, released in 1978.

This processor will be available in limited quantities and for a limited time. The product will come in special commemorative packaging.

Intel announced this processor as their first 5Ghz out of the box consumer desktop processor. Though 5GHz is the maximum default turbo frequency of only one core. The maximum default turbo frequency for all 6 cores is 4.6GHz. Actually, this processor is a 300MHz faster version of the i7-8700K, the flagship of Intel's 8th generation "Coffee Lake" desktop CPUs. The i7-8086K and the i7-8700K only differ in default CPU frequency. Intel's 8th generation CPUs are only compatible with motherboards with the Intel 300 series chipsets.

The price of the i7-8086K on Amazon.com is $425, $75 higher than the i7-8700K. Both are unlocked for overclocking, thus the i7-8700K can definitely be overclocked to the same frequency as the i7-8086K. But to achieve that, a motherboard with the Intel Z370 chipset is needed. Boards with the Intel Z370 chipset are more expensive than those with other Intel 300 series chipsets. While the i7-8086K can be installed on any board with the Intel 300 series chipset and performs in faster CPU frequency out of the box.

In terms of against Meltdown and Spectre vulnerabilities, this processor doesn’t have any hardware level advantage over other Intel 8th generation CPUs, though software level patches have been released to address these issues. Processors with silicon-based changes to address these issues are expected to hit the market later in 2018.
