Dear forum users,

I need to change my actual HP Omen 15 with an ultrabook since this one is really heavy to travel with or go to university.

I'm looking for a 2 in 1 ultrabook with 8550u, ssd and 16gb.

The options as a gamer are microsoft surface or razer blade however I just jumped into knowing that I can choose cheaper solutions attaching a eGPU via thunderbolt 3

I saw here that a notebook needs to have GT4 OPI and 4 lines thunderbolt 3 in order to work properly with egpus with native displays and processors.

There is a guide to follow in order to understand what laptops have those specs? I saw several spectre 360 ae04#ng models and the latest yoga 920 but how i know what are the proper model since there is no trace in understanding if they have or not those requirements?

I plan on attaching an aorus gaming box.

Thanks in advance for any help you would provide me an best regards.

A few quick notes:

- the Microsoft Surface line does not use Thunderbolt, so no eGPUs there (unless you mean the performance base of the Surface Books).

- "properly" might be a stretch, x2 and GT2 laptops will work, but will have a performance penalty (but then, so does using the internal display, so it's more about which compromises you are willing to make).

- Among Spectres, the best one for eGPU setups is very specifically the 13" x360 with 8th gen Intel CPUs (i7 8550). Others will work (15", 7th gen, etc), but will carry a 5-20% performance penalty depending on use-case

Yep, the HP Spectre x360 13" models or Lenovo Yoga 920 both with 8th gen 8250/8550 processors.

Does this include the Spectre 13 T in ceramic white? I like this one because it is the smallest, the most beautiful, And the power input is on the usb 3.1 not on the 2 thunderbolts leaving them both free. Is there anyway to know for sure if it is a 4 laner?

Unfortunately no surefire (outside way) other than someone testing it. Given there isn't an internal NVidia GPU and that it shares some innards with the x360, I'd guess it's likely that it's an x4, but confirmation from an owner would be still the best way.

If your dock has decent power delivery (e.g. 60W or 87W) charging from the TB3 port is ideal.

So HWinfo shows x1 unused, x1 internal attached to wifi adapter, x4 unused, and x4 attached to nvme drive.

My experience has been the rear TB3 port is the x4 that shows as unused (that's where I plug in my egpu). The front one I assume would be the x1.

 

Please note... I have the copper/dark ash x360, not the white one, implementation guide has been posted.

Thank you for all the help.

4chip I was only stating that for gaming I choose among an ultrabook like surface or blade (that actually have built-in GPU but are heavier) or an ultrabook with eGPU. Furthermore, I'll never turn back a 6700hq (omen 15 2016) for a dual core i7. 8550u represent the minimum for me. Grin

I'll go with one of these 2:

lenovo 920 13ikb 80y8001 8550 16gb 512

HP Spectre x360 13-ae004nl 8550 16gb 512

Actually, these are the only solutions available on amazon Italy so I can't choose differently. Is the spectre model fine? I cant find any thunderbolt info about the lines or GT. 🙁

Yes, that HP Spectre x360 is 4 lanes and GT4.

Hi, yes, I believe there is consensus about 13" x360 ones having x4 - I was just referring to the Spectre 13 @lightstrum mentioned, aka "T" Spectre (ie not x360 Spectre), which is a slightly different beast, with a slightly different port layout (has 3 USB-Cs, all from the rear side).
