AMD processor with Vega GPU and 28 compute units appears in SiSoftware database

In the benchmark database of SiSoftware, an AMD processor has appeared that has a built-in gpu with 28 compute units and 2GB of memory. It may be hbm2. The processor is probably a desktop version of Raven Ridge.

The graphics part of the processor is referred to in the SiSoftware database as AMD 15FF Graphics. At the end of October, AMD introduced its Ryzen processors for laptops with built-in Vega GPUs and those models are labeled AMD 15DD Graphics. The laptop versions have a gpu with a maximum of 11 cu’s and therefore 640 stream processors, the alleged desktop variant has 28 cu’s and that is good for 1792 stream processors.

The number of CUs indicates a lot of graphical computing power, because it is equal to half the number of CUs that the Vega 56 GPU has. It is not yet clear whether the desktop processor with built-in Vega GPU will get hbm2. The database states that the chip has 2GB of memory, but the type is unknown. The laptop versions use 256MB DDR4. If the AMD desktop processor actually has its own memory, it would be likely that this is hbm2, because it takes up little space.

The entry in the database makes nothing clear about the CPU part of the processor. However, it is likely that it is a Ryzen processor based on the Zen architecture. The number of cores is unknown. The laptop versions have four cores and eight threads.

In the database of SiSoftware, the name is called AMD Fenghuang Raven. This is probably not the code name of the processor itself, but of the platform. Raven Ridge is the code name of the AMD Ryzen processors with integrated GPUs. The laptop platform is codenamed Mandolin Raven and Fenghuang Raven may be the desktop counterpart.
