Intel seems to be addressing key platform limitations with its 8th generation Core "Coffee Lake" mainstream desktop platform. The first Core i7 and Core i5 "Coffee Lake" processors will launch later this year, alongside motherboards based on the Intel Z370 Express chipset. Leaked company slides detailing this chipset make an interesting revelation, that the chipset itself puts out 24 PCI-Express gen 3.0 lanes, that's not counting the 16 lanes the processor puts out for up to two PEG (PCI-Express Graphics) slots.

The PCI-Express lane budget of "Coffee Lake" platform is a huge step-up from the 8-12 general purpose lanes put out by previous-generation Intel chipsets, and will enable motherboard designers to cram their products with multiple M.2 and U.2 storage options, besides bandwidth-heavy onboard devices such as additional USB 3.1 and Thunderbolt controllers. The chipset itself integrates a multitude of bandwidth-hungry connectivity options. It integrates a 10-port USB 3.1 controller, from which six ports run at 10 Gbps, and four at 5 Gbps.

Ooo look, Intel finally found those PCI-E lanes they kept "loosing" the past few years.

And cores.

z270 already has 24 lanes from the chipset, it also makes little difference over a PLX solution since the DMI3 link does not have that much bandwidth.
