Chinese CPU Maker Debuts 32-Core Chiplet-Based Processor

Building large monolithic many-core CPUs is extremely hard even for renowned chip designers. For Chinese CPU developers, many of whom do not have access to leading-edge production nodes, the only way to build a processor with high core count is to adopt a chiplet design. As it turns out, this is exactly what Chinese CPU maker Loongson does with its 32-core 3D5000 processor, Sina reports.  

Earlier this year Loongson began to ship its 3C5000 processor that relies on 16 LA464 cores featuring the company’s LoongArch microarchitecture, up to 64MB of cache, and four 64-bit DDR4-3200 memory interfaces with ECC support. The Loongson 3D5000 takes two 3C5000 CPUs and places it on a single piece of substrate to build a 32-core processor with eight memory channels. The 32-core processor supports up to 4-way simultaneous multiprocessor configurations and therefore it is possible to build a server with up to 128 cores.
