These 8th generation Core CPUs are going into ultrabooks. The big news is they are now quad-core instead of dual-core CPUs.

Is Intel doing eGPU enthusiasts a favor? Probably not. AMD continues to up the pressure is more likely the reason. AMD Raven Ridge is forthcoming. If you can wait on getting a new ultrabook, definitely hold out until the end of the year.

Here Intel have TDP optimized these new 8th gen ULV CPUs with a higher core count. More cores at lower voltage getting more processing within the TDP than less cores at a higher voltage. Hence the low base frequency available.

A benefit of eGPU users being some can spared CPU package TDP for CPU processing when not using the on-die iGPU for any intensive graphical activity.

Intel  are claiming up to a 40% performance improvement here over their 7th gen counterparts:

Intel, ever tight-lipped about the specific design and manufacturing improvements that go into successive chip generations, didn’t elaborate on how the eighth-generation Core lineup achieves its 40 percent performance gains. In a press briefing last week, however, the company did say that 25 percent of the performance boost comes from adding two more cores (seventh-generation Core i5 and i7 U-series chips have only two cores), while design and manufacturing improvements are responsible for the remaining 15 percent.

I really like those news - heard abou it from leaks day ago. 

It means that I can get ultra slim laptop with great battery usage to go and use it as powerhorse with egpu at home.

Totally agree, my setup is quite perfect now but I would love to have a quad core CPU

Thanks for the rundown - when you suggest waiting for the end of the year before purchasing a new notebook, is this because you think the AMD Raven Ridge APU based eGPU hosts will enable superior performance to the Intel Quad-core 8th-gen U-series, or because notebooks with Intel 8th-gen HQ series chips likely won't be announced/begin shipping until then?

Any specific notebooks coming down the pipeline that you are looking out for?

Think these have the integrated thunderbolt controller Intel mentioned?

At this moment only U-series of 8th gen CPU are available. Specifically 4 models (2 modes of i5 and 2 models of i7). Desktop and H (45watt laptop) versions will be announced this fall whereas first 8th gen U series laptop will be released this September.

@mambo99 I think there will be better options for us to make more informed decision. I’m curious to see what AMD has up its sleeve as far as TB3 laptops go. Here’s an early performance test by WCCFTech.

Thunderbolt 3 is Intel's turf. I wouldn't bet on it being available to AMD...

Dell announced XPS 13 with 8th gen. quad-core CPU. Availability starts on September 12th. It does not appear Dell is changing anything else architecturally with the laptop so x2 PCIe lane over Thunderbolt 3 remains an issue.

HP has a Spectre x360 update listed on their site, rocking the i7 8550U, a single TB3 port, as well as a MX150 2GB GDDR5 (this is essentially a GT1030) dGPU driving a 4K 15" display. My one question about the 8550U and 8650U is how long can they turbo-boost before they drop their clocks. 4 cores are nice, but if they spend most of their time at 2Ghz, then I'd rather have a 3.2Ghz dual-core.

Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

For systems with a dGPU, I’d rather go with an HQ/HK CPU. The improvement in my opinion is to iGPU-only ultrabooks.

I want an iGPU only HQ/HK system in a relatively small form-factor. Judging by the TDPs on the parts, this Spectre could've been one of those (15W CPU + 30W dGPU matches perfectly with a 45W high-end CPU part), and they might have something like this down the like when the HQ/HK parts get released. That would be a perfect eGPU base-platform. Extra points for connecting the TB3 controller and M.2 slots straight to the CPU (seeing as there's nothing else goes there, pretty much), but if it is a design refresh, that is not likely.

We recently saw a forum member reported that the 15″ Spectre X360 has x2 PCIe over Thunderbolt 3 connection. This is most likely the case still.

at the moment there are these systems with a HQ cpu and thunderbolt3 port:

-dell latitude 5570 (930m)

-dell latitude 5480 (940m)

-dell latitude 5580 (940mx)

-dell precision 7520 (igpu)

-hp zbook g4 15 studio (igpu)

-clevo n750hu (igpu)

-clevo n751hu (igpu)

I sort of meant relatively light systems (the Spectre 15" is ~2kg, whereas the ZBook Studio and Clevos are a bit heavier, but pretty close to the mark) with only an iGPU, most of the current systems are relatively large.

To add to your list:

-Lenovo P50/P51 (Various Quadros, including high-end ones)

-HP ZBook G3/G4 (non-Studio) 15/17 (Various Quadros, mostly mid-range)

-MBP2016/MBP2017 15" (Various Radeon Pros)

Oh, those Latitudes do look nice. For some reason I remembered that line being heavier! Very, very nice. Thanks for setting me straight.
