Old hardware?

[Electuur]

Hello,

Which chips are on the TBS6981 and TBS6991?
The TBS6981 is an older card then the TBS6991. Does this mean that it has older hardware then newer card? Is the image quality of the newer card better? Does the newest card have other advantages over the older one, other than the dual CI? Which chips are on the other DVB-S2 PCIe cards?

Is the image quality with Linux equal to the image quality with Windows?

Bye,
Electuur
