The AMD A4-4355M was a mobile processor with 2 cores, launched in September 2012. It is part of the A4 lineup, using the Trinity architecture with Socket FP2. A4-4355M has 1 MB of L2 cache and operates at 1900 MHz by default, but can boost up to 2.4 GHz, depending on the workload. AMD is making the A4-4355M on a 32 nm production node 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 A4-4355M, which limits its overclocking potential. With a TDP of 17 W, the A4-4355M 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 system, A4-4355M uses a PCI-Express Gen 2 connection. This processor features the Radeon HD 7400G integrated graphics solution. Hardware virtualization is available on the A4-4355M, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications.
