The AMD Phenom II P920 was a mobile processor with 4 cores, designed for laptops and launched in May 2010. It is part of the Phenom II lineup, using the Champlain architecture with Socket S1G4. The processor operates at a base frequency of 1.6 GHz and features a total of 4.512 MB of L2 cache. Built on a 45 nm production process, the Phenom II P920 is optimized for energy efficiency with a TDP of just 25 W, making it suitable for portable devices where power consumption is a critical factor.

The processor supports DDR3 memory with a dual-channel interface, running at up to 1800 MHz, providing balanced performance for multitasking and everyday computing tasks. Unlike some high-end desktop CPUs, the Phenom II P920 does not support Hyper-Threading or unlocked multipliers, limiting its overclocking potential.

For communication with other system components, the Phenom II P920 utilizes an integrated memory controller and HyperTransport technology for efficient data transfer. This processor does not include integrated graphics, so a discrete GPU is required for display output. Hardware virtualization (AMD-V) is supported, enhancing performance in virtualized environments.

Overall, the AMD Phenom II P920 was a power-efficient quad-core solution for mid-range laptops, offering a balance of performance and battery life.
