32-bits of DSP is a very substantive technical claim IMHO
The implication we're supposed to draw is that those DSPs are accompanied by at
least 16-bits of A/D & D/A and therefore >90 dB of dynamic range. Limited DR
has been the Achilles heel of doing effective DSP at IF. OTOH if they're still
just feeding those DSPs with 8 or 12-bit flash A/Ds for the IF, then you're
right, it's just hype.
