  • We've cleared the board, and it's time for a rundown of the silicon:

  • Intel Xeon W-2140B (Skylake, 14 nm—likely an underclocked W-2145 to keep the temps in check), 3.2 GHz CPU with Turbo Boost up to 4.2 GHz, paired with what could well be a standard LGA 2066 socket

  • AMD S5J68 1747 GPEW0333S3 SS63HBN181747US40104 Radeon Pro Vega 56 GPU with integrated 8 GB of HBM2 memory (on-package)

  • Intel X723D733 E1 05780 (SR3PV?) - likely platform controller hub

  • AQUANTIA AQtion AQC107-B1-C PCIe to multi-gigabit ethernet controller

  • Pericom Semiconductors PI3PCIE3412AZHE PCIE 3.0 mux/demux switch

  • Apple/Universal Scientific Industrial (USI) 339S00428 00012021 Wi-Fi/Bluetooth module

  • Genesys Logic GL3227A SD 4.0 memory card controller, and Texas Instruments LP8565A13 (likely LED backlight driver)

我们已经清空了主板，是时候来捋一捋这些芯片了

英特尔至强（Intel Xeon）W-2140B（Skylake架构，14 nm制作工艺——像是为了能控制住温度而设计的W-2145的低频版）， 3.2 GHz主频，可睿频至4.2 GHz，带有LGA 2066的CPU插槽

AMD S5J68 1747 GPEW0333S3 SS63HBN181747US40104 Radeon Pro Vega 56 GPU带有8 GB的HBM2内存（内封装）

Intel X723D733 E1 05780（SR3PV?）可能是平台控制芯片

AQUANTIA AQtion AQC107-B1-C PCIe 10Gb 以太网控制器

Pericom Semiconductors PI3PCIE3412AZHE PCIE 3.0 差动开关

Apple/Universal Scientific Industrial （USI） 339S00428 00012021 Wi-Fi/蓝牙模块

创惟科技（Genesys Logic）GL3227A SD 4.0 存储卡控制器，以及德州仪器（Texas Instruments）LP8565A13 （可能是LED背光控制器）
