Intel today announces its eight Core generation of desktop processors with two Core i3 quad-cores, two Core i5 hexacores without HyperThreading and two Core i7 hexacores with HyperTreading.

This new family introduces the first-ever 6-core Intel Core i5 desktop processor and first-ever 4-core Intel Core i3 desktop processor. The family offers a wide range of performance options for consumers with unlocked “K” processors that deliver maximum tuning flexibility at each brand level and up to 40 platform PCIe 3.0 lanes for system expandability on graphics, storage and I/O. These processors are supported with new Intel Z370 chipset-based motherboards.

The announcement shows what has been circulating for a while now, including the specs. Coffee Lake processors are fabbed at 14nm, similar to Kaby Lake, Skylake and Broadwell. The speed gain can be found by the additional cores mostly. The architecture of the CPU and GPU did not change compared to Kaby Lake.
 

 
Combined with the CPU and Z370 chipset you get up to 40 pci-e 3.0 lanes and ddr4-2666 memory support, the proc has x16 available for graphics. See the presentation slides below, the processors are available starting October 5th.
