context_page_description: Loongson is a family of general-purpose MIPS64 CPUs developed at the Institute of Computing Technology, Chinese Academy of Sciences in China. The chief architect is Professor Hu Weiwu. It was formerly called Godson.
  Loongson is the result of a public–private partnership. BLX IC Design Corporation was founded in 2002 by ICT and Jiangsu Zhongyi Group. Based in Beijing, BLX focuses on designing the 64-bit Loongson general-purpose and embedded processors, together with developing software tools and reference platforms.
  STMicroelectronics fabricates and markets Loongson chips for BLX, which is fabless.
context_section_description: There are two versions of the Loongson-3B1500 (Godson-3B1500), the first featuring a 32 nm 6-core processor, and the second version having a 28 nm 8-core processor. Each version can be clocked from 1.2 GHz to 1.5 GHz. Loongson-3B has exceptional energy efficiency in terms of performance per watt - executing 192 GFLOPS using 40 watts. Each CPU core has 64 KB L1 cache and 128 KB L2 cache. All the cores share a common 8 MB L3 cache, which helps to reduce the cache miss rate.
  ICT has launched a Loongson-3B-based six-core desktop solution. Technical specifications:
  Mini-ITX motherboard with Loongson-3B CPU
  ATI RS780E (AMD 780E) southbridge with 128 MB integrated graphics
  ATI SBx00 Azalia on-board audio
  up to 16 GB DDR3 memory
  Intel 82574L gigabit network interface
  PCI, PCIe, 4 SATA ports, USB and other peripheral interfaces
  Can optionally be equipped with AMD HD6770 discrete graphics, and HDD or SSD hard drive
  This desktop solution uses an optimized version of Fedora 13, with a lot of software ported and available, such as Kingsoft (WPS) office suite. The manufacturer states that the user experience of the desktop solution has been significantly improved over its Loongson-3A based predecessor. Results of a benchmark test, conducted in April 2014, are available
