Cavium announces ThunderX2

ThunderX2 targets high performance volume servers deployed by Public/Private Cloud and Telco data centres and high performance computing applications. It is optimized for key data centre workloads such as compute, security, storage, data analytics, network function virtualization (NFV) and distributed databases. ThunderX2 will deliver two to three times the performance across a wide range of standard benchmarks and applications compared to ThunderX. It also significantly expands the market reach of the ThunderX family of processors by targeting applications that require high single thread performance such as web search, graph analytics, a variety of enterprise applications such as massively parallel processing (MPP) databases, data warehousing and enterprise HPC applications such as computational fluid dynamics (CFD) and reservoir modelling. ThunderX2 will deliver comparable performance at a better TCO compared to the next generation of traditional server processors.

ThunderX2 is the second generation workload optimized ARMv8 processor built in the 14nm FinFET process. It is fully compliant with ARMv8.2 architecture as well as ARM's Server Base System Architecture (SBSA) standard.

Key ThunderX2 features will include:

1. 2nd generation of full custom Cavium ARM core.

• Multi-Issue, Fully OOO.
• 2.4 to 2.8GHz in normal mode, Up to 3 GHz in Turbo mode.
• > 2x single thread performance compared to ThunderX.

2. Up to 54 cores per socket delivering 2-3X socket level performance compared to ThunderX.

3. Cache.

• 40K I-Cache and 64K D-cache, highly associative.
• 32MB shared Last Level Cache (LLC).

4. Single and dual socket configuration support using 2nd generation of Cavium Coherent Interconnect with > 2.5X coherent bandwidth compared to ThunderX.

5. System Memory.

• 6 DDR4 memory controllers per socket.
• Dual DIMM per memory controller, for a total of 12 DIMMs per socket.
• Up to 3200MHz in 1 DPC and 2966MHz in 2 DPC configuration.
• Up to 3 TB of memory in dual socket configuration.

6. Full system virtualization for low latency from virtual machine to IO enabled through Cavium virtSOC technology.

7. Next Generation IO.

• Integrated 10/25/40/50/100GbE network connectivity.
• Multiple integrated SATAv3 interfaces.
• Integrated PCIe Gen3 interfaces, x1, x4, x8 and x16 support.

8. Integrated Hardware Accelerators.

• OCTEON style packet parsing, shaping, lookup, QoS and forwarding.
• Virtual Switch (vSwitch) offload.
• Virtualization, storage and NITROX V security.

"The Cavium ThunderX2 will expand the market opportunity for ARM-based server technologies by addressing demanding application and workload requirements for compute, storage networking and security", stated Simon Segars, CEO, ARM. "ThunderX2 demonstrates Cavium's ability to deliver a combination of innovation and engineering execution and the new product family increases the momentum for server deployments powered by ARM processors in large scale data centers and end user environments."

ThunderX2 family of processors include, four workload optimized processors targeting different workloads:

• ThunderX2_CP: Optimized for Cloud compute workloads such as private and public Clouds, web serving, web caching, web search, commercial HPC workloads such as computational fluid dynamics (CFD) and reservoir modelling. This family supports multiple 10/25/40/50/100 GbE network Interfaces and PCIe Gen3 interfaces. It also includes accelerators for virtualization and vSwitch offload.
• ThunderX2_ST: Optimized for Big Data, Cloud storage, massively parallel processing (MPP) databases and Data warehousing workloads. This family supports multiple 10/25/40/50/100 GbE network interfaces, PCIe Gen3 interfaces and SATAv3 interfaces. It also includes hardware accelerators for data protection/ integrity/security, user to user efficient data movement.
• ThunderX2_SC: Optimized for secure web front-end, security appliances and cloud RAN type workloads. This family supports multiple 10/25/40/50/100 GbE interfaces and PCIe Gen3 interfaces. Integrated hardware accelerators include Cavium's industry leading, 5th generation NITROX security technology with acceleration for IPSec, RSA and SSL.
• ThunderX2_NT: Optimized for media servers, scale-out embedded applications and NFV type workloads. This family supports multiple 10/25/40/50/100 GbE interfaces. It also includes OCTEON style hardware accelerators for packet parsing, shaping, lookup, QoS and forwarding.

"ThunderX2 combines our next generation core that will deliver significantly higher single thread performance with next generation IO and hardware accelerators to provide a compelling value proposition for the server market and greatly expand the serviceable server TAM", stated Syed Ali, President and CEO of Cavium. "ThunderX2 will enable flexible, scalable and fully optimizable servers for next generation software defined data centres."

Cavium's ThunderX2 SoC family is supported by a comprehensive software ecosystem ranging from platform level systems management and firmware to commercial Operating Systems, Development Environments and Applications. Cavium has actively engaged in server industry standards groups such as UEFI and delivered numerous reference platforms to a broad array of community and corporate partners. Cavium has also demonstrated its leadership role in the Open Source software community driving upstream kernel enablement for ThunderX, actively contributing to Linaro's Enterprise and Networking Groups, investing in key Linux Foundation projects such as Xen and OPNFV and sponsoring the FreeBSD Foundation's ARMv8 server implementation.
