AmpereOne Family Product Brief
AmpereOne™ is the next generation of Cloud Native Processors from Ampere, extending the family of high-performance processors to new industry leading core counts. The AmpereOne Family establishes new levels of performance and VM density for computing solutions at scale.
AmpereOne compliments the existing Ampere® Altra® products and adheres to the same Cloud Native principles:
Ampere is more. More cores, more memory bandwidth, more memory capacity, more IO bandwidth, and more Cloud Native features.

Cloud Native Features
The AmpereOne Family picks up from the top end of the Ampere Altra Family, offering products from 136 cores up to 192 cores operating at consistent and predictable frequencies of up to 3.0 GHz. Each core is single-threaded by design with its own 16 KB L1 Instruction-cache, 64 KB L1 Data-cache, while doubling the L2 private cache to 2 MB.
Large private caching, consistent operating frequency, single threaded cores, and new memory management features combine to deliver predictable performance by mitigating the noisy neighbor challenges in multi-core processing architectures while providing a very secure microarchitecture for multi-tenant cloud environments.
A coherent mesh interconnect provides efficient bandwidth with 64 distributed home nodes and directory-based snoop filters to enable seamless connectivity between the cores. AmpereOne also adds Mesh congestion management and QOS enforcement features further augmenting the predicable behavior of data movement in high core count products.
Supporting eight 80-bit DDR5 channels, the AmpereOne Family offers an improvement in memory bandwidth and a larger addressable space of up to 8 TB of memory.
Using industry leading power efficiency per core, the AmpereOne family provides high performance processing products up to 192 cores providing further scalability to deploy dense compute for the most demanding compute installations on the planet, especially in hyperscale data centers.
AmpereOne dense Cloud Native Processors deliver the most cores per rack, maximize the number of servers per rack, and provide the highest performance per rack for the most sustainable and power- efficient computing installations in the industry.
The AmpereOne Family provides consistent incremental performance on a per core basis. Workloads scale linearly as more processes are added to the single-threaded cores. For dense virtual machine implementations, more VMs can be provisioned on an AmpereOne high core count processor than any other compute product in the industry.
With up to 128 lanes of PCIe Gen5 (32 GT/s per lane) per socket, the AmpereOne Family provides the flexibility to add up to 32 off-chip devices, including networking cards, storage/NVMe devices, GPUs, and other accelerators. AmpereOne platforms are well suited to a variety of system configurations delivering the highest performance for large capacity storage, networking, AI inference, and the newest generative AI models and applications.
The AmpereOne Family leads all other server compute products in this key metric: performance per rack. This allows operators and IT designers unprecedented compute capacity for high-density compute environments. This advantage reduces rack and floor space, trims power requirements for operational efficiency, and saves money. Carbon footprints are drastically reduced allowing managers to meet aggressive ESG goals and shorten the time to Net-Zero emissions initiatives.
The densest compute products in the AmpereOne Family allow Cloud Native workloads to scale out providing maximum rack capacity and outperforming legacy x86 products at the rack level. This efficiency can reduce operational IT budgets by 10s to 100s of millions of dollars.
The AmpereOne Family includes new advanced power management features: Advanced Configuration Power Interface (ACPI) v6.4 support; Adaptive Voltage Scaling (AVS); Dynamic Voltage Frequency Scaling (DVFS); fine-grained thermal monitoring and power provisioning; and dynamic power estimation.
|Speculative Side Channel Attack Mitigation||Additional protection against a class of potential attacks that use side channels|
|Buffer Overflow Protection/Memory Tagging||Prevents a class of potential attacks that use buffer overflow to compromise data|
|ROP/JOP Attack Mitigation||Prevents a class of potential attacks that use types of application exploits used in the past to compromise processes in execution|
|Crypto and Entropy Acceleration||Improves performance for RNG, SHA512, SHA3 cryptography algorithms|
|Single-Key Memory Encryption||Protects memory from being maliciously read by unauthorized actors|
