We can better compare what are the technical differences between the two processors.

Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

We see that the two processors have an equivalent number of cores, the maximum frequency of Amlogic S905X3 is greater, that their respective TDP are of the same order. The Amlogic S805X2 was started more recently.

Performances :

Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench 4.

There are still no results in the benchmark platforms for at least one of these processors. Please come back later.
