In late 2023 I reviewed the HP Z6 G5 A workstation that at the time was built around the AMD Ryzen Threadripper PRO 7000 series and NVIDIA RTX Ada Generation graphics. More recently, HP has revised the Z6 G5 A workstation for the latest Threadripper PRO 9000 series and NVIDIA RTX PRO Blackwell graphics. HP sent over the upgraded Z6 G5 A workstation that I've been benchmarking the past few weeks. This workstation remains Linux-friendly down to convenient LVFS/Fwupd support and delivers stellar performance with the Zen 5 Threadripper and NVIDIA Blackwell combination.
