Correction note: this page previously described the Z2 Mini G9 as charging over 90W USB-C PD, offering a 96GB memory option, a Xeon processor and an “RTX A500” GPU. None of those is correct for this machine — it takes a 180W or 280W external adapter through a DC barrel jack, tops out at 64GB of DDR5-4800, ships 12th-Gen Core processors only, and its professional GPU options are the T400, T600, T1000 and RTX A2000 12GB.
