Boost clock
Boost clock	2,581 MHz	1,710 MHz or 1,800 MHz
Architecture
Architecture	AMD reference specification; 40 compute units and 17.2 billion transistors. AMD's current product table labels 1 March 2021 as the launch date, but its announcement specifies 18 March as the first on-sale date used here.	Main figures follow NVIDIA's reference specification. Founders Edition raises boost clock and board power. Photo shows MSI's stock-clocked RTX 2080 AERO 8G partner board, which uses a blower rather than the Founders Edition's dual axial fans.
