Dell XPS 15 9570

The Dell XPS 15 9570 is considered a "MacBook Pro killer". It has amazing performance for around half the cost. As with many laptops, there is some configuration require to make all the components work with Gentoo.

History
The Dell XPS 15 9570 is the updated version of the 9560 models. Released in May 2018, this model supports several choices in hardware configurations. Namely,


 * The CPU can be one of the new Coffee Lake quad-core Core i5, hexa-core Core i7, or Core i9 processors.
 * The graphics subsystem can consist of solely an Intel Integrated GPU or both an Intel Integrated GPU and NVIDIA GeForce GTX 1050Ti GPU.
 * An optional fingerprint scanner integrated into the power button.
 * There is a choice of touch FHD (1920x1080 @ 60.00 Hz), non-touch FHD (1920x1080 @ 60.00 Hz), touch UHD (3840x2160 @ 60.00 Hz), or non-touch UHD (3840x2160 @ 60.00 Hz) for the screen.
 * The choice of a 2.5 SATA SSD or M.@ PCIe NVME SSD.

Additionally, the 9570's Thunderbolt 3 port now supports all four PCIe lanes, unlike the previous models, which only had support for two lanes.

Wireless card
Remove the Killer Wireless-AC 1535 card and replace it with the Intel Wireless-AC 9260. According to this forums discussion, the Intel card is vastly superior to the Killer card in every way.

The Intel Wireless-AC 9260 can be purchased [//www.amazon.com/Intel-Wireless-Ac-9260-2230-Gigabit/dp/B079QJQF4Y/ref=sr_1_2?keywords=intel+wireless+ac+9260&qid=1553136796&refinements=p_85%3A2470955011&rnid=2470954011&rps=1&s=gateway&sr=8-2 on Amazon.]

Heat and CPU throttling
The 9570 has a serious issue with dissipating heat which sometimes leads to throttling [//www.notebookcheck.net/Some-Dell-XPS-15-9570-laptops-may-have-a-BIOS-related-GPU-bug.355026.0.html][//www.dell.com/community/XPS/Dell-XPS-15-9570-i9-thermals-throttling-and-solutions/td-p/6116619][//www.reddit.com/r/Dell/comments/98cyam/power_limit_throttling_xps_15_9570/].

In most cases, this can be solved by updating the motherboard firmware with the latest images from Dell's 9570 support page. However, if the issue still persists, following [//www.ultrabookreview.com/14875-fix-throttling-xps-15/ this tutorial] may produce better results.
