Hello, I'm from Greece and I'm trying to choose the best laptop for me. At first I was going for a budget gaming laptop in order to buy a big pc in the near future. I thought that this will cost me around 1800-2000€.
So I thought that it's best to buy a premium laptop that will be future proof, at least for the next three years.
I will need it for gaming, video editing etc.
I'm between these 2:
The first has a ryzen 7 4800h with A rtx 2060,
The second one has a Intel i7 9750h with a rtx 2070.
The first has a better cpu and the second one a better gpu.
I really think that the second one is better because it has a thunderbolt 3 and therefore I can buy a egpu in three years when me internal gpu may feel obsolete.
Do you think that the i7 cpu will be a problem for my future proof plans?
I saw the benchmarks and it's worse than the ryzen but too close, just a little behind.
Do you think that the idea with the egpu is a bad one?

If it`s mainly about the gaming you should go with the "dell g5", as most games are GPU dependant.
The 2070 mobile is quite powerfull - it will be hard to best this via an eGPU.
At least you should do some research before buying an expensive eGPU setup:
- TB3 will give you an performance hit about 20%
- 9th core H CPUs have the TB3 connected to them via an seperate PCH that will limit performance even more!

TB3 will give you an performance hit about 20%
what you mean by this? is it max. performance hit regardless of internal GPU?

.@ultrasilent, Ah sorry! As a rule of thumb: If you use any GPU as an eGPU for a notebook you will face a 20% performance hit.
So if your 2070 in a regular PC will offer 100% performance the exact same 2070 used as egpu will offer you about 80% of that performance.
Considering that the 2070 inside the notebook that offers Thunderbolt 3 is a really good card you will have to buy a really really powerfull GPU in order to best the that 2070.
Especially as the (like I said) i7-9750H has the eGPU connected to the CPU by an external PCH chip that will limit bandwidth even more.
That`s all I was talking about.

Can you please explain what kind of options do we have in modern laptops regarding this and how to understand which option is realized in a given laptop? Which options give us 20% performance hit and how much limited are another options?
what you can say regarding this one:

.@ultrasilent, at first I have to give credit to itsage and nando, from which I learned about what I am going to tell you:
1.) every eGPU connected via TB3 / TB4 will take a performace hit due to limited bandwith (2 or 4 lanes only)
2.) An external Monitor will decrease this performance hit as the information will be sent diretly to the video out of the egpu and has not to be transported back to the internal screen.
3.) The higher the resolution the less critical is the performance hit, still the overall FPS will take a hit.
4.) There are some games (ecspecially the UBI ones) that perform absolutely terrible on any eGPU -> Assassin`s Creed fans beware!
5.) ALL 8th, 9th and I guess even 10th gen H processors utilize an external Platform Controller Hub (PCH) which decreases the performance of the eGPU by an aditional 10-15%. 7th gen hq Processors have their PCH integrated I guess - at least my 7700hq performance with the very same eGPU was about 12% better than the performance with my actual 9750H.
6.) MacBooks make an exception from this rule as far as I know.
7.) Most U/G Processors utilize an integrated PCH an therefore might be preferable when planing to use an eGPU - however the older models where not as capaple as the H processors, but I guess we are approaching a point where the U and G processors are getting comparable.
Hope this is somewhat helpful

@phila-delphia, so, if I my config looks like this:
OMEN 17 7700HQ 1070M TB3 up to 40 gbit/s
which eGPU will double my 4k gaming FPS in case of external 4к TV? nvidia 3080 desctop? or TB3 will not use all potential of this powerfull card?

Hi I can play Apex Legends on 4K (RX 5600XT, build in signature) but 45-60 FPS and somewhat choppy ("TB3 20% reduction" in performance due to bandwidth limitations).
Your 7700HQ is a decent laptop CPU and your TB3 with Razer X and perhaps RTX 3060Ti or 3070 may give you decent 4K performance (but you have to reduce settings to Low-Medium for AAA titles).
3080 or above is probably a waste as there's lots of horsepower being "wasted".
Just my opinion from being a new eGPU user.
FWIW in my build for Apex Legends 1080p I can get 55-100FPS if I make some settings High and some settings Low, and set VRAM budget to 4GB (so less data transfers through the TB3 for textures I think).
Cheers.
Yes, the problem might be: While the 7700HQ does not suffer the extra performance loss due to PCH it has a clear deficit in multiplayer titles (fewer cores).
If you are aming for singleplayer titles - then you can go for it. If you want you can have a look at the following thread where I show the performance differences between 7700qh and 9750hq (with the 7700 besting the 9750 in all titles that are not to cpu dependant): https://egpu.io/forums/pc-setup/less-egpu-performance-with-better-notebook/
All the best
