The AMD Sempron 3850 was a desktop processor with 4 cores, launched in April 2014. It is part of the Sempron lineup, using the Kabini architecture with Socket AM1. Sempron 3850 has 2 MB of L2 cache and operates at 1300 MHz. AMD is building the Sempron 3850 on a 28 nm production process, the transistor count is unknown. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. The multiplier is locked on Sempron 3850, which limits its overclocking capabilities.
With a TDP of 25 W, the Sempron 3850 consumes only little energy. AMD's processor supports DDR3 memory with a single-channel interface. The highest officially supported memory speed is 1600 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Sempron 3850 uses a PCI-Express Gen 2 connection. This processor features the Radeon R3 128CU integrated graphics solution.
Hardware virtualization is available on the Sempron 3850, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
