The Loongson-3A2000 and -3B2000 are four-way superscalar processors built on a nine-stage, super-pipelined architecture with in-order execution units, two floating-point units, a memory management unit, and an innovative crossbar interconnect. The 3A2000 is said to be aimed at the high-performance consumer electronics market while the 3B2000 will be used in a number of home-grown eight and 16-core server systems.
The 3B series also features Loongson-3B1500, a MIPS64-based superscalar processor claimed to be clocked at 1.5GHz. Platforms integrating the3B1500 are alleged to deliver up to 192GFLOPS of peak performance at 30W.
Benchmarking data released recently showed the CPUs surpassing several competing processors in performance efficiency (SPEC CPU2000 per GHz), including ARM Cortex-A57 and AMD E1-2100. These performance figures also show a 2.7x improvement in performance over the Loongson-3A1000 and -3B1000 previous generation cores.
