XGS vs XG : NGFW Throughput (Gbps)

hello,

In XG documentation , there are these values about NGFW Throughput  (Gbps)

XG 330    NGFW Throughput  (Gbps)    9.3

XG 430    NGFW Throughput  (Gbps)    10

XG 450    NGFW Throughput  (Gbps)    13.9

But I can't find these values in XGS documentation,

so what is the (NGFW Throughput  (Gbps)) for :   XGS 3300,  XGS 4300, XGS 4500 ?

thanks
