Intel formally announced its 9th generation Core mainstream desktop processors on October 8, 2018 at its Fall Launch Event in New York. So far, they have announced three members of this family. The prices below are the MSRP prices. Actual street prices are a currently little higher, especially for the Core i9-9900K. Supply is also a little tight so far.

The Core i9-9900K has a base clock speed of 3.60 GHz, a Turbo clock speed of 5.0 GHz, and 16MB of L3 cache. The Core i7-9700K has a base clock speed of 3.60 GHz, a Turbo clock speed of 4.9 GHz, and 12MB of L3 cache. Finally, the Core i5-9600K has a base clock speed of 3.70 GHz, a Turbo clock speed of 4.6 GHz, and 9MB of L3 cache. These processors are aimed at gaming and general desktop usage. They are competitors to AMD’s Ryzen 2xxx mainstream processors.

You may have noticed that Intel has dropped hyper-threading (HT) from the Core i7 line (which is something it has always had, and was one of the main differentiators over the Core i5 line in the past). The lack of HT means a loss of about 25-30% of your overall CPU capacity when you have the same number of physical cores.

These new processors have soldered thermal interface material (rather than thermal paste) which will help with heat dissipation, and let them run more cores at slightly higher (100-200MHz) clock speeds more often. They also have hardware-level mitigation for some of the Meltdown CPU exploits, which will result in better performance than software mitigations.

These new processors will all work in existing Intel 300 series chipsets (with an updated BIOS), but Intel is also introducing a new Z390 chipset, which is a very slight improvement over the previous Z370 chipset, primarily with native USB 3.1 Gen 2 support and built-in 802.11ac Wi-Fi support. Here is the list of Z390 motherboards from NewEgg, while AnandTech has a roundup of Z390 motherboards here.

Intel also announced a new generation of high-end desktop (HEDT) processors, which are the Core X-Series processors. These processors use the LGA2066 socket on X299 motherboards. There are seven SKUs in this family.

These processors are designed to compete with the AMD Ryzen Threadripper HEDT processors. Unlike previous generation Intel HEDT processors, every one of the SKUs in this family support 48 PCIe 3.0 lanes.
