OK, more precisely (I did refer to the release notes of 12.2(20)S in my
previous email) the 7304 is a PXF platform when using a NSE-100.
The 7304 can be used with either a NPE-G100 (stated as 1M PPS, 3xGE) or
NSE-100 (stated as 3.5M PPS by PXF, 450k PPS non-PXF, 2xGE).
Of the PXF platforms:
NSE-1 263MHz RM7000 "100MHz PXF"
NSE-100 350MHz RM7000 "3.5M PPS PXF"
7401ASR 375MHz RM7000 "PXF based on NSE-1"
The NSE-100 is a faster version of the NSE-1, and probably faster than
the 7401ASR. Not clear if all the PXF based performance is equal or
not between the three platforms; the 7401ASRs describe their PXF as
"tmc type TMC ASIC revision 2".
