Stratix 10 Devices SoC or not?

Hey all,

I was going through some of the Stratix 10 Devices to help myself understand the offerings available, however I noticed that several devices in this family such as the Stratix 10 TX, Stratix 10 DX are not marketed as SoC, however they both have an HPS much like an SoC would. Currently only the Stratix 10 SX is the only family with an HPS that is also marketed as an SoC.

Am I missing something here that makes the TX and DX devices not SoC? And if I am looking for a devices in the Stratix 10 Family that is not an SoC, am I limited to the GX and MX Families?
