Mystery AMD APU with 1,792 SP Shows Up on SANDRA Database
A mysterious AMD APU showed up on SiSoft SANDRA online database, featuring a massive integrated graphics. The chip reports itself to SANDRA as "AMD Fenghuang Raven," and is likely a semi-custom chip being tested by an AMD engineer in the course of its development. SANDRA reports the integrated graphics component as "AMD 15FF Graphics," featuring 1,792 stream processors across 28 compute units, 555 MHz engine clock, and 2 GB of video memory with 182.15 GB/s memory bandwidth. The result doesn't put out too many details about the CPU component, except its 2.40 GHz clock speed. The iGPU scored 98 points on SANDRA graphics tests with Direct3D 11 API, and 39.99 GB/s observed score.

What gave it up, is a massive memory bandwidth (read "HBM2").
So, either it's a "beefed-up" version of Core+Vega, but for compute or workstations (the one announced for laptops earlier only has 24CUs), or AMD is working on their own version with Ryzen core and better Vega... Probably to empower Baidu in the conquest to take over the world. :D
AMD has to concentrate on the large volume segments: mobile and server. So any "APU" news is important.
As of December 2017 - almost a year of Ryzen and few months of Vega - the first one is almost non-existent in notebooks and the best implementation of the latter is in currently developed Intel's MCM.
And assuming TPU is publishing a press release for every large client that chooses EPYC over Xeon, there are clearly not many of them as well...
Desktop high-end parts (both CPU and GPU) are niche products. Seriously, no one beside gaming/nerd communities cares about them.
And BTW: do you remember how few months ago people here got excited by market share estimations on PassMark? It looked like AMD share is going to explode. The more optimistic AMD fans expected it to reach 30% by the end of the year. And what happened?

I assume you're aware of this as well:

Vega is just screwed anyway you look at it. Raja touted a bunch of features that ended up doing nothing. People can defend the man all they want but this is the biggest dud of a video card since Nvidi'a Fermi.
Interesting :)
Elite APU? this would be most powerful APU of all time with 28 vega CUs
BTW: I needed some info for work and I had to go through AMD's pages. They are a mess! Almost worse than those of Taiwanese motherboard manufacturers...

Nah it could be
In a typical modern datacenter, which mixes CPUs and GPUs (or coprocessors like Xeon Phi), the two types of processors complement each other. CPUs are better at some types of calculations, GPUs are better at others.
If you need more GPU potential, you just add a GPU. There's really no point in adding an APU, which is inherently slower than a PCI-card variant on the same architecture.
Moreover, from a practical standpoint, it's fairly important to have identical GPUs in the system.
And BTW: CPUs also cover the "maintenance" tasks - like moving data around (disks <-> RAM <-> GPU), so replacing them with APUs could actually bottleneck the whole system, not make it faster.
