> This 2 in 1 laptop has some power to give and the only 5cm fan seems to do the job with nice TDP profiles :

>> Performance : PL2 64W / PL1 40W

>> Balanced : PL2 51W / PL1 28W

>> Silence : PL2 45W / PL1 25W

Yes there is some throttling and it can only sustain between 35 and 40W (3,7 and 3,9GHz) but that's still impressive for a 14" convertible.

 

>> I might use this device as my new daily device : good perf, good battery life (70wh - 9 to 10 hours video playback), contained external thermals, painless eGPU usage, ...

@wildfear, Thank you for the detailed build. This Yoga 7i 14ITL5 looks like a great eGPU host. Are the Samsung Galaxy Book Pro laptops available in your market? It's coming to the US later this week. I pre-ordered a 15-in version which has i7-1165G7 and an OLED display. I've found Samsung laptops to have very good build quality. We'll see about the cooling system.

Another nice build! How would you compare this Yoga 7i to the E13 Flip you tested a few weeks ago? I'm aware the Lenovo is cheaper and has slightly better benchmarks results. How do the build quality, keyboard, pen input, handling etc compare?

Dell Latitude 5290 2-in-1 (i7 8650u, 16GB LPDDR3) + Lenovo ThinkPad X1 Tablet 3rd Gen (i7 8550u, 16GB LPDDR3) + Mantiz Saturn Pro V2 + RTX 3070

@mrcat, actually I think this Lenovo Yoga is a more balanced device for a good price. 

Materials and hardware are not as premium E13 but seems more durable and sturdy.

I also prefers lenovo software and ergonomy for my use.

That said, about your questions : keyboard is good, pen is good but not great, handling is nice.
