2018 13" MacBook Pro Rumors
An article on winfuture.de shows a Geekbench screen capture of the 2018 13" MacBook Pro. This new model sports an i7-8559U CPU. This processor has 28W TDP and 16 PCI lanes. If the specs turn out to be true, this will make a great host laptop for eGPU use.
Top spec of the 2017 13" MBP Touchbar has i7-7567U. This CPU has 12 PCI lanes. The right TB3 controller uses a 2-lane connection because right TB3 controller uses 4, NVMe uses 4, and wireless card uses 1. The new CPU with 16 PCI lanes will afford Apple to use 4 lanes for the right TB3 controller in the 2018 MBP.
Can't wait for it, 13" quad-core is perfect for eGPU.

Thats near 15inch multicore score... I wonder if thermal throttling will be an issue... and if I get tempted to upgrade.
I have always preferred the footprint of the 13" MacBook Pro. The refresh later this fall will close the gap in terms of performance (quad-core CPU and 4x PCIe lanes to both TB3 controllers). My bet is we'll see new MacBook Pros when Mojave launches. The past three macOS versions' launch dates are the last weeks of September.
It would be interesting to hear if there are any firmware updates on these machines because eGPU implementation changed a fair bit from 2016 > 2017 (large memory) and with the 2017 firmware update rumoured to make AMD cards easier in Bootcamp I'm wondering if anything has changed on the 13's this year?
@karm I had mine for about 3 weeks and returned it. As you may have seen there are thermal issues on these 2018 MBPs. Apple rolled out an update for macOS but it did not help with Boot Camp. The Apple T2 chip is definitely a big deterrent of unsupported configurations. I also encountered issues with newer firmware in Mojave Beta removing Large Memory allocation in Windows.
I got the 15" MBP and I got mixed feelings. They released it too early in my eyes because the software (High Sierra) isn't really ready for these Macs. Since I installed Mojave it solved a lot of issues. Just the Bootcamp drivers and the firmware is still awful. But all in all I like it. It's a damn powerful machine and if Apple finally would fix those bugs it'd be a perfect pro user laptop. (And I didn't expect mixing the Radeon dGPU and a Nvidia eGPU would be so easy)
