The AMD PRO A8-8650B was a desktop processor with 4 cores, launched in September 2015. It is part of the A8 lineup, using the Godaveri architecture with Socket FM2+. PRO A8-8650B has 4MB of L2 cache and operates at 3.2 GHz by default, but can boost up to 3.9 GHz, depending on the workload. AMD is building the PRO A8-8650B 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 A8-8650B, which limits its overclocking capabilities.
With a TDP of 65 W, the PRO A8-8650B consumes typical power levels for a modern PC. AMD's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 2133 MHz, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer, PRO A8-8650B uses a PCI-Express Gen 3 connection. This processor features the Radeon R7 integrated graphics solution.
Hardware virtualization is available on the PRO A8-8650B, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
