Amd ryzen 1700x and 1800x have intentional error in temperature reading

The new AMD Ryzen processors have arrived with a high-quality thermal bond between the die and the IHS, something that provides optimal heat conductivity to improve dissipation efficiency, a situation completely contrary to Intel processors that have serious problems to cool properly.

AMD Ryzen has an offset in its temperature

Analyzes of the Ryzen 7 1700 have shown that the processor works at excellent temperatures, however its older siblings, the Ryzen and 1700X and 1800X, have been found to achieve higher temperatures. AMD has reported that the models with XFR technology, that is, the Ryzen and 1700X and 1800X, present an intentional error in the reading of their temperatures, an error of no less than 20ºC.

This is something that can confuse users but the reason for this is quite simple in our opinion, XFR technology is an automatic overclock that works based on temperature. The intentional error in temperature reading is intended to allow XFR to do its job perfectly so that processors can perform at their best while leaving a margin of safety. AMD claims that the software will soon be able to read the temperature of these models correctly when needed.

We believe AMD has been successful in using high-quality solder between the processor die and the IHS, something that allows processors to dissipate the heat generated excellently. This is essential given the innovative XFR feature that Sunnyvale's have introduced in their new Zen microarchitecture. Reading error is something that gets users quite confused and we don't really see any benefit to it, AMD has adjusted its XFR technology to It does not pose any problem in Ryzen processors, so we do not see the need to show a temperature 20ºC higher than the real one.
