One of the largest cloud providers in China, Alibaba, has today announced a preview for a new instance powered by Yitian 710 processor. The new processor is a collection of Alibaba’s efforts to develop a home-grown design capable of powering cloud instances and the infrastructure needed for it and its clients. Without much further ado, the Yitian 710 is based on Armv9 ISA and features 128 cores. Ramping up to 3.2 GHz, these cores are paired with eight-channel DDR5 memory to enable sufficient data transfer. In addition, the CPU supports 96 PCIe 5.0 lanes for IO with storage and accelerators. These are most likely custom designs, and we don’t know if they are using a blueprint based on Arm’s Neoverse. The CPU is manufactured at TSMC’s facilities on 5 nm node and features 60 billion transistors.
Alibaba offers these processors as a part of their Elastic Compute Service (ECS) instance called g8m, where users can select 1/2/4/8/16/32/64/128 vCPUs, where each vCPU is equal to one CPU core physically. Alibaba is running this as a trial option and notes that users should not run production code on these instances, as they will disappear after two months. Only 100 instances are available for now, and they are based in Alibaba’s Hangzhou zone in China. The company notes that instances based on Yitian 710 processors offer 100 percent higher efficiency than existing AMD/Intel solutions; however, they don’t have any useful data to back it up. The Chinese cloud giant is likely trying to test and see if the home-grown hardware can satisfy the needs of its clients so that they can continue the path to self-sustainability.
