AMD processor with 28 compute unit based Vega GPU appears in SiSoftware database

AMD processor with 28 compute unit based Vega GPU appears in SiSoftware database

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.

Time will tell, but this is an interesting spot alright.

This is probably the Ryzen 5/7 "Gaming" i was alluding to in the other thread about the new Roadmap.

This will make for some sweet gaming machines, with pretty good power consumption.

I would suspect the full shader compliment to be about 2048 Shaders.
Only 2GB of memory seems low, I would have expected 4GB as a minimum nowadays...

edit : It seems like its using system memory from the screencaps.

Would, in combination with a GPU, the driver recognize this as a multi GPU setup? Would be some nice extra horsepower.

This is exactly what I thought as well. " Buy a powerful Ryzen CPU wih powerful integraded graphics and combine it with a radeon GPU" Smart scenario in my opinion which would boost Ryzen and Radeon sales.

At this rate AMD APUs with powerful enough GPUs to reasonably play games will be available before MSRP priced Vega stock.

On TPU, they have another screen cap from Sandra that shows 182.15GB/s of memory Bandwidth.
That would equate to HBM2 at ~700MHz effective speed, on a 2048bit bus.
The Up and Down transfer speeds are close to 8GB/s, which to me, would indicate a PCIe3 x8 connection with the CPU (which should be plenty for this type of GPU).

Edit : FengHuang is also apparently translated in the West to "Chinese Phoenix" or just "Phoenix"...
