Not true.  7401 has a PXF.  It's essentially an NSE-1 with GE/IO in a
pizza box.  7301 is based on the NPE-G1 and doesn't have a PXF anywhere
in sight.  

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".
