Our base model may look a bit bare, but there's still plenty of silicon on this massive slab:

2x aQuantia AQtion AQC107-B1-C multi-gigabit ethernet controller

2x Diodes Incorporated PI3DBS16 PCIe Thunderbolt 3 signal mux

Pericom (acquired by Diodes Incorporated) P17C9X PCIe packet switch

TPS 51980A TI 921 A57R buck converter

PLX Technology PEX8798-AB80B1 G 1907 CB007158 TA1BAN, probably a PCIe switch

3x Primarion (acquired by Infineon) PXE1610CDN, most likely PMIC
