The AMD Phenom II P940 was a mobile processor with 1 core, designed for laptops and launched in May 2010. It is part of the Phenom II lineup, using the Champlain architecture with Socket S1G4. AMD Phenom II P940 has 4.5 MB of L2/L3 cache (combined) and operates at 1.7 GHz base frequency, with a maximum turbo frequency of 1.8 GHz depending on thermal conditions. AMD manufactured the Phenom II P940 on a 45 nm production process. With a TDP of just 25 W, this processor is highly power-efficient for mobile applications, making it suitable for thin-and-light laptops. AMD's processor supports DDR2 memory with a dual-channel interface, though actual memory speed support depends on the system configuration. For communication with other components in the system, Phenom II P940 uses a HyperTransport 3.0 connection. This processor lacks integrated graphics, so a discrete graphics card is required. Hardware virtualization (AMD-V) is available on the Phenom II P940, which improves virtual machine performance. The processor also supports AMD's PowerNow! technology for dynamic power management.
