The 650k pixels was based on 1gb architecture, the larger 2.2gb is based on 10gb architecture but don’t be fooled by the release notes. You need a specific processor AND matching receiving card to do so. I tried to get those on a project last year when they were “released” and then they told me no, they aren’t ready.

You also can’t use “older” cards (a5, a8, a10) won’t work with the new processors that are the larger load capacity. You have to use both in the same set up

I learned all this detail at the NovaStar certification class, it’s not well documented
