Using performance results, we can compare these two cards.
This is the comparation radar graph of NXP JCOP 21 V2.2 36K and NXP J3A081 JCOP v2.4.1.
The values closer to 100% represent the times close to the fastest result among all tested cards, whereas values close to 10% suggest slower performance in the corresponding algorithm. Value of 0%(NS) indicates a lack of support or occurrence of unexpected error during the tested algorithm.
