recently,AMD quietly updated the specification page of Ryzen Ruilong and ECYC Opteron processors, and began to add a variety of parameter annotation information, especially the "Max Boost Clock", which is officially interpreted as a single core in normal operating environment. The highest frequency that can be achieved.
PCIe version, TDP thermal design power, system memory bandwidth, etc. also have their own annotations, but it may be just beginning to update, some of the entries are not in place, such as Ruilong's explanation is still Xiaolong.
in fact,IntelThere is a similar approach. There are clear explanations for many specifications in the ARK database, including the “Max Turbo Frequency”, which is the same as AMD and is the single core maximum frequency.
For example, the Ruilong 7 3700X has a nominal reference frequency of 3.6 GHz and a maximum acceleration frequency of 4.4 GHz. The measured core can have a core (thread) up to about 4.38 GHz (4375 MHz), while other cores (threads) will be at 4218-4371 MHz. Not equal.
The i9-9900K has a nominal reference frequency of 3.6 GHz and a maximum core frequency of 5.0 GHz. The measured one can run to 4975 MHz, and the other 4438-4700 MHz.
