As far as the standard power range goes, the list of new SKUs includes the Core i5-8600, Core i5-8500, and the Core i3-8300. Both the Core i5-8600 and Core i5-8500 are six-core SKUs without Hyper-Threading support, 9MB of cache, 65W TDP, support for dual-channel DDR4-2666 memory, and Intel vPro support.
These parts will fill the gap between the currently available Core i5-8600K and the Core i5-8400. The Core i3-8300 is a quad-core part without HyperThreading and support for Intel Turbo Boost 2.0 technology, 62W TDP, 8MB of cache and official support for slower DDR4-2400 memory, like all Core i3 parts.
In addition, Intel also released a total of six Core i7, Core i5 and Core i3 low-power parts, including the Core i7-8700T, Core i5-8600T, Core i5-8500T, Core i5-8400T, Core i3-8300T and the Core i3-8100T. All of these parts are pretty similar to their standard power counterparts in terms of core count and cache size but work at lower clocks and fit in the 35W TDP range.
In addition to the new 8th gen Core Coffee Lake desktop SKUs, Intel released its new 300 series chipsets, including the H370, Q370, B360 and the H310. Compared to the currently available Z370 chipset, these bring new integrated 802.11ac WiFi, support for USB 3.1 Gen2 (10Gbps) directly from the chipset, support for Intel Smart Sound technology (except for the H310 chipset), support for Intel Optane Memory (except for the H310 chipset) and support for Modern Standby.
New chipsets mean that Coffee Lake parts will finally get cheaper motherboards which should chime with the newly introduced Core i5 and Core i3 parts, pushing Coffee Lake into a wider range of consumers.
Plenty of motherboard makers have already started to announce their motherboards based on new chipsets and new CPUs are likely to be already available from a wide range of retail/e-tail shops and/or OEMs and system integrators.
