                At the end of 2017, Intel launched their latest Coffee Lake (8th Gen) CPU with up to 6 cores and 12 threads along with their associated Z370 chipset motherboards. Unlike the move from Skylake to Kaby Lake, Coffee Lake CPUs require new motherboards to function properly – despite all three CPUs using the LGA 1151 socket. The benefit here is that CPU coolers compatible with previous Skylake and Kaby Lake CPUs will work perfectly with Coffee Lake. Just like Z270, the Z370 chipset carries over the unique abilities of overclocking your CPU and the use of multiple graphics cards (e.g. Nvidia SLI & AMD Crossfire). This guide will assist you in understanding the difference between the Intel Z270 vs Z370 chipsets.


                Along with supporting Coffee Lake CPUs, Z370 chipset motherboards offer a few additional native features over Z270.

                A new feature supported by the Z370 chipset is USB 3.1 Gen 1. This new generation of USB provides the same transfer speed as standard USB 3.0 however increases the power delivery to 100W. The increased power delivery can be very useful as it allows many devices such as Ultrabooks to be charged without needing an AC power brick. USB 3.1 Gen 1 also brings with it support for USB Type-C which provides an improved user experience due to the reversible connector. Though not supported natively by Z370, some motherboard vendors provide USB3.1 Gen 2 support with both rear I/O ports and as an internal header designed to be used with a case’s front panel USB 3.1 Gen 2 port.* USB3.1 Gen 2 doubles the data transfer bandwidth – up to 10Gbps from 5Gbps of USB3.1 Gen 1.


                Although a new type of USB may seem like a measly new feature of the Z370 chipset, motherboard vendors such as ASRock, Asus, EVGA, Gigabyte and MSI have included unique features for example multiple M.2 ports, Thunderbolt support, Wi-Fi, RGB lighting, USB 3.1 Gen 2 and much more.


                Overall, supporting Intel’s newest Coffee Lake (8th Gen) CPUs is the most noteworthy new feature of the Z370 chipset. Intel Z370 motherboards should be at the top of your shopping list if you are planning to upgrade or build a new PC and wish to overclock and/or run multiple graphics cards.
