Hello everyone !

 

Next step in my research for best perf/thermals/noise with tiger lake laptops.

I used the same the same eGPU of my main setup :

2020 15" Lenovo Legion 7i (RTX2070S) [10th,8C,H] + RTX 3080 @ 32Gbps-TB3 (Razer Core X Chroma) + Win10 20H2

> This laptop have great heat dissipation hardware with to big fans and vapor chambers.

> It can handle 45/50W at max fan speed and 90-92 °C

> TDP in perfo mode is PL2 64W / PL1 45W

 

> On software side it's not that good, HP have some work to make it responsive and user friendly

> Also, with usbc/thunderbolt as power source, it throttle TDP going to PL2 45W-40W / PL1 40W-35W 

> You have to reboot with AC adapter on only then hotplug EGPU to get full max TDP/power again

 

> I think this laptop without dgpu could have been a eGPU pairing beast 

Edit : seems the iGPU version exist in the US but not in my country :

It's quite possible the unit without a dGPU might have weaker cooling and not be able to maintain 45W PL1. I can't seem to find a teardown of the one without a dGPU to compare, even HP themselves have a video of how to replace parts on the one with a dGPU.

Indeed, but I can't check by myself, dGPU only units aren't available here :/

I'll continue my research to replace my lenovo 7i by another laptop with TB4 (thank to french local laws I can order, test and return if I'm not satisfied ^^)

@wildfear, I wouldn't worry about it too much, you can just disable the dGPU in device manager and take advantage of the beefy shared cooler for the CPU alone.  I guess call the price of the dGPU a thermal management tax. Smile

 

It could be that the one with iGPU only has the same heat pipe and fan arrangement just without the piece that sit on the dGPU.

Here's the video at the timecode of removing the heatsink for those that might happen across your build:

 Perhaps iGPU only just doesn't have the dGPU plate but same pipes and fans.. I think that might be wishful thinking though. Shruggie. I Dont Know

Disabling dGPU without mux switch or bios option result in dGPU staying on and drawing power.

You get better battery life and thermals with dGPU enable and optimus set to iGPU priority.

The main issue the constant stuttering while having both nvidia dGPU and eGPU enable at the same time, didn't found any real solution to that :/

For the battery issue, I use a personnal powershell script (with a task to start it at windows login) on my lenovo to automatically activate / desactivate dGPU when eGPU is plugged or unplugged.

Here the script if someone wants it :

Spoiler
Script dGPU swap

@wildfear, nice. Conditionally doing it sounds the best route as with the eGPU I would imagine it's on power by means of PD. Just need someone to test out the iGPU only one I guess as the best option. Smile
