A recent paper published in the IEEE’s “Transactions on Cloud Computing” journal highlights that Alibaba’s Yitian 710, released in 2021, is currently the most powerful and energy-efficient Arm-based cloud server processor.
The Alibaba Yitian 710 is manufactured using a 5nm process, employs a pure 64-bit Armv9 instruction set architecture, has 128 cores, 1MB of L2 cache per core, and a shared 64MB L3 cache. It features a maximum clock speed of 3.2GHz, supports eight-channel DDR5 memory, and provides 96 PCIe 5.0 lanes.
Alibaba claims it’s the most powerful Arm server chip in the industry, outperforming the industry benchmark by over 20% and improving energy efficiency by over 50%. It is primarily used in Alibaba Cloud data centers.
The tests compared several competitive products, including Intel Xeon Platinum 8848C (32 cores/3.2GHz/105MB), Kunpeng 920 (60 cores/2.4GHz/32MB), Ampere Altra (80 cores/3GHz/32MB), and Amazon Graviton 2/3 (64 cores/2.5/2.6GHz/32MB).
Among these, Intel’s processor uses the x86 instruction set, while the others follow the Armv8 instruction set.
In eight tests, the Alibaba Yitian 710 performed consistently well compared to its Arm-based competitors, with the sole exception being in Excel.
Even against the x86-based Intel Xeon Platinum 8848C, the Yitian 710 held its ground, matching it in the Dhrystone and Whetstone benchmarks.
The paper also notes that, in addition to its impressive performance, the Alibaba Yitian 710 features a leading instruction set, DDR5 memory, PCIe 5.0 lanes, and a larger L3 cache, all achieved in 2021.
