The SiSoftware database is revealing an entry of an AMD processor for which the GPU has 28 compute units and 2 GB of memory. The processor could be the desktop equivalent of Raven Ridge.

The IGP of the processor is referred to as AMD 15FF Graphics in the SiSoftware database. Denoted as:" AMD 15FF Graphics (28CU 1792SP SM5.2 555MHz, 16kB L2, 2GB 2.4GHz".

A few weeks ago AMD announced its Ryzen processors for laptops with built-in Vega-GPU and AMD 15DD Graphics. The laptop versions have a maximum 11 CU's and thus 640 shader processors, the desktop version has 28 CU's (x64) = 1792 shader processors.
 

 
What is very interesting as the memory is being read out as 2GB, it's indicative to be tied to the GPU and could be HBM2. I am saying the carefully though, as HBM2 would be very, perhaps too, expensive for an IGP part. The database name is listed as "AMD Fenghuang Raven", not very likely the code name of the processor itself, but the platform. Raven Ridge is the code name of the AMD Ryzen processors with integrated GPU. The laptop platform is codenamed Mandolin Raven and possibly Fenghuang Raven is the counterpart for desktops.
