RX100 video IQ impressive

just wondering if the rx100 trumps slightly older camcorders. I have a handycam HDR-TG7 and trying to figure out if I should sell it and put towards the RX100.

Heres what it looks like:

It's about 2/3 years old now but I still love the form factor and it's simplicity. I assume the audio would still be better even on an old camcorder and the zooming probably easier but for IQ I am interested in how it compares. From the specs my camcorder has I think16Mbps recording at 1080i so apart from progressive and a slightly higher bitrate I am not sure the RX100 would be so much better?

Perhaps some of you could help me?

Rick
