It looks like the bandwidth, you max bandwidth achievable is 3.3Gbps, 1.65Gbps\165 Mhz per channel.
Meaning your source can only stream that much information to your AVR/Destination, you might be able to achieve HDMI 1.2 max, which is rated at 4.95 Gbps @ 165 Mhz.
Since your device max is 3.3Gbps you might get audio or video drop outs if you run a 3D High Def source with DTS HD Master audio or something like that.
I'm not saying it will happen, but it is a possibility.
If you look at the NGear device it is rated up to 10.2 Gbps which lines up with the HDMI 1.4 spec, which means I should be able to support 4K video, 3D, ARC, and DTS HD Master audio all at the same time.
Theoretically at least.
