Using performance results, we can compare these two cards.
This is the comparation radar graph of NXP JCOP 31 V2.2 36K and NXP JCOP4 P71D321.
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.
