Intel® Xeon® Silver 4210 Processor Is Running with about Half or a Lower Base Frequency

Environment

Intel® Xeon® Silver 4210 Processor (13.75M Cache, 2.20 GHz)

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Summary

Provides troubleshooting that why an Intel® Xeon® Processors may be running with about half or lower Base Frequency than listed in the processor's specifications

Description

Intel® Xeon® Silver 4210 Processor (13.75M Cache, 2.20 GHz) is showing a base frequency of 1.1 GHz instead of 2.20 GHz.

Resolution

The processor might be running at lower frequency than expected due to one of the following reasons:

  • The processor is operating in AVX-512 (Advanced Vector Extensions-512) or AVX 2.0 mode which supports a lower base frequency.
    • The Intel Product Specifications website lists the Base Frequency of 2.2 GHz for Non-AVX mode. 
    • For example: The Intel® Xeon® 4114 Processor operating in AVX-512 mode will support a Base Frequency of 1.1 GHz but in Non-AVX mode will support 2.2 GHz.

    More details about AVX-512.

  • Highly parallel or vectorized applications generating the highest load on the processor cores may require more power and generate more heat and thus may lower the frequency.
