How Good are Pakistani tank ammunition rounds

[Blitz Falcon 3536]

I'm a little confused as due to big difference in penetration power of anti tank rounds of various countries . This is because their are many ways to measure penetration in RHA armor and other countries use different methods.

So I searched a lot and did not find how Pakistan does it . I'll be straight, according to Pakistan ordinances factories Pakistani fin stabilized penetrateor rounds has 450mm penetrating power inside RHA armor while the Americans brand their latest rounds to have 750+mm penetrating power.

How good are Pakistani rounds in modern combat really?
