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
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.
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.
Base Frequencies and Maximum Core Frequencies for Non-AVX, AVX 2.0, and AVX-512 modes are listed in the processor family's Specification Update:
- 1st Generation Intel® Xeon® Scalable Processors Specification Update
- 2nd Generation Intel® Xeon® Scalable Processors Specification Update
- 3rd Generation Intel® Xeon® Scalable Processors Specification Update
