If you come across any particularly interesting posts with technical details, part numbers, fixes, or how-tos, let me know and I will include them on this list.
Many of these link back to the Notebook Review forum, which is going offline on January 31. I will change the links to point to the NBR Precision archive once I have it ready.
Upcoming systems: Precision 7670 & Precision 7770
CPU — Intel Alder Lake HX (12th gen) – Intel 7 process, hybrid architecture, 8P + 8E cores, bump up to 55W TDP
GPU — NVIDIA Ampere refresh – RTX A5500 with GA103S chip; 7,424 CUDA cores; 16GB vRAM; similar performance to GeForce RTX 3080 Ti Laptop GPU
DDR5 (up to 128GB)
PCIe4 support — Alder Lake S-BGA supports 36 lanes of PCIe4 (20 at CPU and 16 at PCH), so all NVMe slots in the system should be PCIe4 enabled
Expected to be available to order in mid/late second quarter 2022; could be earlier, primarily depends on release timing of Alder Lake HX CPUs, which is currently unclear
