Multi-core Architecture
Two CPU dies, each with up to 32 cores and 4 DDR4 controllers.
One I/O die provides the PCIe interface, Ethernet interface, storage controller, inter-chip cache coherence interface, and hardware acceleration engine.
System on a Chip
A single chip integrates the CPU, southbridge, NIC, and drive controller, while supporting multiple data encryption, decryption, compression, and decompression mechanisms.
Superior Performance
2.9 times higher integer computing performance compared with the previous-generation single processor
Increased parallel computing performance in big data, software-defined storage, and database applications
Massive Throughput
60% higher memory bandwidth with eight DDR4 channels
66% higher I/O bandwidth with PCIe 4.0
Four times the network bandwidth with 100GE Ethernet
Inter-chip Interconnection
The Huawei Cache Coherence System (HCCS) bus provides coherent access to the system memory for kernels, devices, and clusters.
Up to 480 Gbit/s inter-chip bandwidth allows interconnection of up to four Kunpeng 920 processors and supports a NUMA architecture with up to 256 physical cores.
