The VIA Nano QuadCore L4800 is a mobile processor with 4 cores, launched in May 2011. It is part of the Nano Quad lineup, using the Isaiah (CNQ) architecture with VIA nanoBGA2. Nano QuadCore L4800 has 1 MB of L2 cache per core and operates at 1466 MHz by default, but can boost up to 1600 MHz, depending on the workload. VIA is building the Nano QuadCore L4800 on a 40 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 L4800, which limits its overclocking capabilities. With a TDP of 28 W, the Nano QuadCore L4800 consumes only 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. Hardware virtualization is available on the Nano QuadCore L4800, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications.
