As the leader of mobile processors, arm has not been ambitious to compete in the data center processor market for a long time. Therefore, it has specially launched the neovere processor platform. Last year, it launched the first generation of neoverse N1, and now it has released the new generation of neoverse N2 and neoverse V1 processor platforms.

Since the launch of neoverse N1 in March last year, several manufacturers have launched high-performance platforms based on neoverse N1, and have won the support of Amazon and other manufacturers.

The launch of the new generation of neoverse processor platform positioning is more clear, the official divided it into three series——E series focuses on energy efficiencyPower consumption and core area should be prior to performance,N series performance, power consumption and area, parallel capability is strong (i.e. more cores), andV series is a new one, focusing on high performance and larger core.

The neoverse V1 series is now available for 7Nm and 5nm processes, andThe neoverse N2 series is oriented to 2021 and mainly adopts 5nm processAfter 2022, there will be a more powerful Poseidon platform for 5nm and 3nm processes, and the performance will be improved by more than 30%.

Specifically, neoverse V1 focuses on high performance,Therefore, the performance of St single core is improved by more than 50% compared with neoverse N1It also supports 2x256bit SVE scalable vector extensions (SVE), which is a high-performance floating-point instruction set jointly developed by arm and Fujitsu. At present, the supercomputing fukuku, the top 500 performance, is realized by SVE performance.

From the data given by arm,The performance of SVE 2x256bit is more than 80% higher than the previous neon 2x128bitThe power consumption is reduced by 40-50%.

As for the neoverse N2 processor platform, it is the authentic successor to neoverse N1,St core performance increased by 40%.

In addition, neoverse N2 not only pays attention to performance, but also attaches importance to parallel performance. It can flexibly match cores according to different loads.

For example, in such an environment as 5g base station, 8-16 cores can be used, and the power consumption is controlled at 20-35w. For 5g edge calculation, 12-36 cores can be selected, and the power consumption is no more than 80W.

In a high-performance scenario like cloud data center,Up to 32-192 cores, 80-350w power consumption space, everything depends on the demand.

The biggest problem with arm as a data center is still ecology, so arm has made a lot of efforts in this respect,The new generation of neovere platform also adds ccix and CXL interconnection branchesIt not only provides leading processor cores, but also provides scalable switching network for partners to support a large number of processor cores.

In addition, arm has also worked with software ecosystems, and the purpose of working with project Cassini is to provide a smooth experience for software developers.

Through standards, platform security and reference implementation, project Cassini gives industry partners confidence in deploying "install as you go" software on ARM based platforms.

last,Arm also continues to promote infrastructure software support, operating systems, hypervisors such as Xen, KVM, docker containers, and more and more kubernetes have announced support for the arm architecture.

Many open source projects initially driven by arm are becoming autonomous, and commercial ISV applications are evolving.
