P3D V4 Performance on 8550U laptop with 1080ti TB3 eGPU

[alswg1994]

I'm considering to sell the desktop computer and replace it with 8550U/16GB(DDR4-2400 Dual-ch). Also I'll buy Thunderbolt 3 eGPU kit and GTX 1080TI for desktop for connecting to that laptop.

The performance of I7-8550U about the same performance as 7700HQ(=desktop 4790). 

The performance hit of TB3 eGPU is about 20-30% when using laptop's display and the fps is high. If using 4K external monitor, the performance hit is lower than 10% even when using GTX 1080TI.

Also I think P3D doesn't really use multicore much, even V4. Also I saw 4790K(stock clock) has near fps compared to 8700k(stock clock), so even IPC/clock difference on CPU seems not to affect P3D v4 performance.

So, how do you guys think about it? Can a 8550U+GTX 1080ti TB3 eGPU laptop deliver enough power to play 4K P3D v4 with rich graphic options and addons like PMDG/REX/etc.?

Today's laptops are generally capable of running P3D with decent Frame rates and visuals. However, what many people tend to ignore: still today, the proper cooling of laptop processors and graphic cards is still an issue. Means: while for a short benchmark, those laptops usually run at the max processor speed and GPU speed without issue, but when flying around for several hours, heat might become a factor resulting in throttling of both CPU and GPU.
