The VIA Nano QuadCore C4650 ES is a desktop processor with 4 cores, that was never released. It is part of the Nano Quad lineup, using the Isaiah II architecture with VIA Socket 2084. To further increase overall system performance, up to two Nano QuadCore C4650 ES CPUs can link up in a multi-processor (SMP) configuration. Nano QuadCore C4650 ES has 2 MB of L2 cache and operates at 2000 MHz. VIA is building the Nano QuadCore C4650 ES on a 28 nm production process, the transistor count is unknown. The silicon die of the chip is not fabricated at VIA, but at the foundry of TSMC. The multiplier is locked on Nano QuadCore C4650 ES, which limits its overclocking capabilities.
With a TDP of 18 W, the Nano QuadCore C4650 ES consumes very little energy. VIA's processor supports DDR3 memory with a single-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. This processor does not have integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Nano QuadCore C4650 ES, 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, VIA is including the newer AVX2 standard, too, but not AVX-512.
