AMD CPUs description mismatch

Question

Looking through the technical guide for the R6515, https://i.dell.com/sites/csdocuments/product_docs/en/poweredge-r6515-technical-guide.pdf
noticed that the listed clock speeds on some CPUs do not match documentation from AMD, for example the 7373X lists on AMD's site with a base clock of 3.05Ghz, (https://www.amd.com/en/products/processors/server/epyc/7003-series/amd-epyc-7373x.html) but in the technical guide it shows 3.80Ghz. Does the PowerEdge automatically boost these to full capacity when installed?
On the other hand, a 73F3 matches on the technical guide and the AMD website: https://www.amd.com/en/products/processors/server/epyc/7003-series/amd-epyc-73f3.html

This discrepancy seems to only exist on these "X" CPUs, but I haven't gone through every line yet.

Any input is appreciated

Mtexter,

Dell’s technical guides sometimes list the maximum boost frequency rather than the base clock, especially for CPUs with variable boost behavior like the EPYC “X” series (e.g., 7373X). These CPUs are designed with 3D V-Cache and may have different thermal and performance profiles depending on system cooling and BIOS settings.

The PowerEdge R6515 does not automatically boost all cores to max frequency, but it does support Precision Boost and CPPC (Collaborative Power and Performance Control), which allows the CPU to dynamically boost based on workload and thermal headroom.

Let me know if this helps.

Hello, I don't quite know if you are having an actual problem with one of those CPUs or if you happen to be just browsing internet for any mismatches but for what I know, it's all platform specific. For example, here, R6525 does not have an option for 73F3 at all. https://i.dell.com/sites/csdocuments/Product_Docs/en/poweredge-r6525-technical-guide.pdf
