The AMD A8-4555M was a mobile processor with 4 cores, launched in September 2012. It is part of the A8 lineup, using the Trinity architecture with Socket FP2. A8-4555M has 4MB of L2 cache and operates at 1600 MHz by default, but can boost up to 2.4 GHz, depending on the workload. AMD is building the A8-4555M on a 32 nm production process using 1,303 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on A8-4555M, which limits its overclocking capabilities.
With a TDP of 19 W, the A8-4555M consumes very little energy. AMD's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1333 MHz, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, A8-4555M uses a PCI-Express Gen 2 connection. This processor features the Radeon HD 7600G integrated graphics solution.
Hardware virtualization is available on the A8-4555M, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
