The AMD GX-420GI was a mobile processor with 4 cores, launched in February 2016. It is part of the G-Series lineup, using the Excavator architecture with Socket FP4. GX-420GI has 1 MB of L2 cache and operates at 2000 MHz by default, but can boost up to 2.2 GHz, depending on the workload. AMD is building the GX-420GI 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 GX-420GI, which limits its overclocking capabilities.
With a TDP of 15 W, the GX-420GI consumes very little energy. AMD's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 1866 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, GX-420GI uses a PCI-Express Gen 3 connection. This processor features the Radeon R7E 6CU integrated graphics solution.
Hardware virtualization is available on the GX-420GI, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
