GT/s = Giga-transfers per second; MB/s = Megabytes per second. Communication occurs via packets

: The highest layer, responsible for generating and receiving Transaction Layer Packets (TLPs). It handles requests like memory reads/writes and configuration cycles. : The highest layer, responsible for generating and
