The "Mandolin Raven" sample spotted in the SiSoft database is a quad-core, eight-threaded model with a 3.0GHz base frequency and a 3.3GHz Boost clockspeed. It has 512KB L2 cache per core and a shared 4MB L3 cache. The GPU part of the chip consists of 11 Compute Units with 64 stream processors per CU, resulting in a total of 704 Vega-based stream processors. The clockspeed of the GPU is 800MHz.
FUD Zilla speculates this model may be a mobile APU, although the frequency seems quite high for that:
We still do not have any details whether this is a desktop or a mobile APU and although it has an "M" in its codename, it has a rather high clock for a mobile part. Earlier unconfirmed roadmaps suggested that AMD Raven Ridge APUs would range from 35W to 95W, which means these will cover a wide market range.
