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 4 MB 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 MT/s, 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.
