2018 models ship with Intel's eighth-generation Core i5 (https://ark.intel.com/products/135935/Intel-Core-i5-8259U-Processor-6M-Cache-up-to-3_80-GHz) or Core i7 processors (https://ark.intel.com/products/137979/Intel-Core-i7-8559U-Processor-8M-Cache-up-to-4_50-GHz), which both support up to 16 PCI Express lanes, providing enough bandwidth for maximum data transfer speeds up to 40Gb/s on all four Thunderbolt 3 ports.





2016 and 2017 models of the 13-inch MacBook Pro with Touch Bar could be configured with sixth- and seventh-generation Intel Core i5 (https://ark.intel.com/products/97535/Intel-Core-i5-7360U-Processor-4M-Cache-up-to-3_60-GHz) and Core i7 processors (https://ark.intel.com/products/97541/Intel-Core-i7-7567U-Processor-4M-Cache-up-to-4_00-GHz), which supported up to 12 PCI Express lanes, limiting full speeds to the two left-side Thunderbolt 3 ports, with reduced bandwidth on the right-side ports (https://www.macrumors.com/2016/10/28/macbook-pro-tb3-reduced-pci-express-bandwidth/).





Now, users have the freedom to plug higher-performance peripherals into any Thunderbolt 3 port they desire without compromise.





All three generations of the 15-inch MacBook Pro with Touch Bar have always had four full-speed Thunderbolt 3 ports, while the 13-inch MacBook Pro with function keys has only two Thunderbolt 3 ports, both full speed.
