Looks to me like the Samsung chipset is klunky compared to the competitor:

"...Samsung's HD Radio baseband processor, based on Tensilica's
programmable core, integrates the baseband, memory, SDRAM and flash in a
system-in-package measuring 9 x 9 mm. Including the companion RF chip,
the chip set's total power consumption is 150 mW...

...Sunder Velamuri, vice president of marketing at SiPort, said power
dissipation of the mixed-signal device is expected to be "around 100 mW
in typical configurations." He added that the chip, essentially "a
software radio," can tune and demodulate not only analog AM/FM and HD
Radio but also DAB and DMB-T, making it ready for the global market.
Taiwan Semiconductor Manufacturing Co. is fabricating the device..."

There are no chips developed for HD radio. Sansung and TI have some
years old notes on how you can use a set of their respective general
purpose chips DSP/CPU and analog baseband devices to make an HD radio.
For these parts to work as an HD radio they need additional support
devices and the license to use the ibiquity software. A lot of power
must be used to drive all this.

That's not what it says. It says it uses ca. 100 mW in "typical
configurations". It says it "can tune and demodulate" so I would think
any "additional support devices" wouldn't be that big a deal.
