Which is faster a BS2P or a BS2SX?

I was wondering as to which chip is faster?
The BS2p or the BS2sx.
The overview info at Parallax looks like it implies that the BS2p can
execute lines of code faster than the BS2sx, but they seem to
advertise that the SX is the faster chip based on it's clock speed?
Thanks
Earl

The BS2sx clock is faster but the BS2p actually runs code faster. The BS2sx
runs code in "PIC compatibility mode" which means that its 50 MHz oscillator
gets divided by four. The BS2p runs in turbo mode at 20 MHz -- undivided.
What this means is that the BS2p runs code faster while drawing less current
than the BS2sx.
