Architecture and compatibility notes
Arc A770 belongs to Intel’s Xe-HPG Alchemist discrete graphics generation. The local GDDR6 configuration and PCIe link are part of the board record; actual negotiated PCIe speed and width are limited by the host slot, firmware and platform.
For a reliable deployment record, retain the exact board SKU, subsystem/device IDs, motherboard and firmware versions, driver package, operating system, PSU model and display connection path. Intel’s Resizable BAR guidance explains the platform prerequisites; it is a platform feature, not a board connector.
