Bottlenecking with egpus

Hi, I've been considering to buy a laptop to replace my Desktop and use an egpu to play games on the go. This way I can bring my laptop anywhere, and when I get home, I simply plug in the egpu(with a gtx 1080 FE inside). Specifically, I am looking at the dell xps 13 9360, and the Razer core v2 for the egpu. However, I've ran into a problem with bottlenecking! I've looked at all the CPUs that the xps 13 can have, and they are mainly i7 7560U, i7 8550U, i5 8250U, and i5 7200. If I plug in the Razer core v2 with a 1080 FE inside, will the xps bottleneck, and if so how bad will it be? Which xps laptop will handle the 1080 the best, and does the egpu affect this?

It will bottleneck (even with the 8550U) unfortunately. Still nothing unplayable tho

Not just CPU bottleneck, but TB3 bottleneck as well. My expectation will be half to 70% the performance compared to desktops with the same graphics card.

CPU: i7-2600K 4751MHz 1.44V (software) --> 1.47V at the back of the socket Motherboard: Asrock Z77 Extreme4 (BCLK: 103.3MHz) CPU Cooler: Noctua NH-D15 RAM: Adata XPG 2x8GB DDR3 (XMP: 2133MHz 10-11-11-30 CR2, custom: 2203MHz 10-11-10-26 CR1 tRFC:230 tREFI:14000) GPU: Asus GTX 1070 Dual (Super Jetstream vbios, +70(2025-2088MHz)/+400(8.8Gbps)) SSD: Samsung 840 Pro 256GB (main boot drive), Transcend SSD370 128GB PSU: Seasonic X-660 80+ Gold Case: Antec P110 Silent, 5 intakes 1 exhaust Monitor: AOC G2460PF 1080p 144Hz (150Hz max w/ DP, 121Hz max w/ HDMI) TN panel Keyboard: Logitech G610 Orion (Cherry MX Blue) with SteelSeries Apex M260 keycaps Mouse: BenQ Zowie FK1
