Boost clock	1,733 MHz or 1,759 MHz	1,710 MHz or 1,800 MHz
Architecture
Architecture	GP104; 7.2 billion transistors; 160 texture units and 64 ROPs. Main specifications and photo describe the original Founders Edition; the later 11 Gbps memory version is represented by MSI's GAMING+ 8G in its default Gaming mode.	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.
