AmpereOne Scaling from 32 to 192 Cores, Core-for-Core Benchmarks vs. Altra Max

The recent benchmarks of the AmpereOne A192-32X processor demonstrate its performance scaling from 32 to 192 cores, with a focus on core-for-core comparisons against the Ampere Altra Max M128-30. The testing utilized a Supermicro ARS-211M-NR R13SPD 2U server platform, revealing that the AmpereOne processor maintains a consistent clock speed of 3.2GHz across all cores, even when cores are offlined. However, the base power consumption remains high, with idle consumption not dropping below 100 Watts, significantly higher than competitors like Intel Xeon and AMD EPYC, which can idle in the 10-30 Watt range. The absence of Simultaneous Multi-Threading (SMT) allows for better performance in scalable workloads, particularly beneficial for cloud and virtual machine applications. The current AmpereOne lineup starts at 96 cores, indicating a gap in offerings for lower core counts, which may be addressed in future updates. Overall, the AmpereOne A192-32X shows promising scalability and efficiency in high-core count environments, although power consumption remains a concern.

- AmpereOne A192-32X scales effectively from 32 to 192 cores.

- The processor operates consistently at 3.2GHz across cores without turbo modes.

- Idle power consumption is notably high, exceeding 100 Watts.

- The lack of SMT benefits performance in cloud and VM workloads.

- Current offerings start at 96 cores, leaving a gap for lower core count processors.
