LS3C5000L
Loongson 3C5000L is a general-purpose processor developed by Loongson Technology specifically for servers. Based on the Loongson 3A5000 processor, the chip integrates 16 high-performance LA464 cores and utilizes LoongArch, a proprietary ISA of Loongson. It features a higher integration level while keeping its system and software fully compatible with the Loongson 3A5000.
