The AMD PRO A10-8850B was a desktop processor with 4 cores, launched in September 2015. It is part of the A10 lineup, using the Godaveri architecture with Socket FM2+. PRO A10-8850B has 4 MB of L2 cache and operates at 3.9 GHz by default, but can boost up to 4.1 GHz, depending on the workload. AMD is building the PRO A10-8850B on a 28 nm production process using 2,411 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on PRO A10-8850B, which limits its overclocking capabilities. With a TDP of 95 W, the PRO A10-8850B consumes a good deal of power, so decent cooling is needed. AMD's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 2133 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, PRO A10-8850B uses a PCI-Express Gen 3 connection. This processor features the Radeon R7 integrated graphics solution. Hardware virtualization is available on the PRO A10-8850B, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
