Ryzen 7 3800x reaches different 'boost' frequencies depending on the motherboard
Table of contents:
People have been seeing slight differences in performance and some have complained that the boost frequency of Ryzen processors is not being reached. Colleagues in the unboxed hardware have taken the trouble to use a Ryzen 7 3800X and test it with 14 models of motherboards to see what the behavior of the processor is and if boost frequencies are reached.
Ryzen 7 3800X 'boost' frequencies vary by motherboard
AMD Ryzen 7 3800X underwent a great comparison with 14 different motherboards. The same processor and the same cooling system were used in each case to prevent temperatures from affecting the results.
Comparative test
Cinebench R20 was run three times in a single core test and the maximum boost clock was recorded at HWiNFO64 . Ryzen 7 3800X achieved a boost clock of 4, 500 MHz on a number of six motherboards. Then, three motherboards reached 4, 475 MHz and two 4, 465 MHz. A total of three motherboards could not reach clocks higher than 4, 375 MHz, it does not seem that AGESA (firmware) has much impact on the boost clock.

The worst is Biostar, which is the worst result with the latest version of AGESA. It's not uncommon to see performance tweaks, for example all major brands also have optimizations for Intel processors for example turbo all cores on ASUS motherboards with Intel processors. Chances are they are doing it to gain an edge over the competition and to position motherboards a bit better based on performance. This is an interesting finding that could have an impact on the choice of a motherboard, especially for performance enthusiasts.

Amd would have lowered the frequencies 'boost clock' in ryzen 3000
AMD had been too aggressive with the boost clock, and with a view to improving reliability, those frequencies would now have been lowered.
