The problems with the Intel Iris Xe (i)GPU archiecture in connection with USB-C and Thunderbolt docking stations.

I bought a new notebook (a gaming Asus TUF Dash F15 notebook, which I want to use as a workstation notebook), which also has an Intel Iris Xe iGPU (alongside an NVIDIA Geforce RTX3070). And that has exactly the same problems as my Samsung Galaxy Book Pro (also with Iris Xe iGPU) with USB-C and Thunderbolt docks with external monitors, with random dropouts and display timing mismatch problem. So there seems to be a general problem with the new Intel Iris Xe GPU architecture regarding the DisplayPort protocol over USB-C and Thunderbolt. Because I have six different USB-C and Thunderbolt docks, and with all of them the problems occur with these two different notebooks, each with an Intel Iris Xe (i)GPU. And of course, I've also tested through different cables and as well as different monitors, with absolutely no improvement. 

My new Samsung Galaxy Book Pro 13

I now have a Samsung Galaxy Book Pro 13 which weights only 868 grams. Unfortunately it‘s only the variant with the i5 and soldered 8GB RAM, because the variant with the i7 and 16GB RAM is no longer available and even nowhere in stock in the German DACH area. But I have already planned a BGA soldering upgrade to 16GB or even 32GB RAM by an expert in the field, where I am currently looking for someone who can do this for me. That means desoldering the old LPDDR4X RAM chips and soldering the new LPDDR4X RAM chips. Unfortunately BGA soldering is only possible with a professional infrared soldering device and the required skills to handle the soldering on the small scale of the chips. 

At the very least, the Samsung Galaxy Book with the i5-1135G7 beats my Thinkpad T480 with the i5 8250u and 32GB of RAM hands down in plain CPU performance, for the simple reason that the Samsung notebook simply throttles less often, if at all, whereas the Thinkpad T480 throttles frequently, if not almost always, and that's … (read more)
