The Amazon page shows pictures of a few chips in the UV-5R vs. GT3. I design circuits for a living and have access to a database of most of the worlds chips so I looked them up.
One chip handles the commercial broadcast FM (music) band. The GT-3 has an incremental improvement over the old chip. It only handles FM music, so it doesn't matter for us.
The next chip handles the 2M & 70cm bands. It also looks like an incremental improvement over the old one, but I can't get a full data sheet on the new one. Since they kept the same part number and chip package and I don't see anything really different in the radio's descriptions, I'm guessing the difference between the chips isn't great.
The 3rd chip drives the speaker/headphones.
So, of the 3 chips, only 1 might make a difference to us and I haven't read anything that tells me there is a difference I would notice. My next Baofeng won't be a $63 GT-3.
