Intel NUC Based on Intel+Vega MCM Leaked
The first product based on Intel's ambitious "Kaby Lake-G" multi-chip module, which combines a quad-core "Kaby Lake-H" die with a graphics die based on AMD "Vega" architecture, will be a NUC (next unit of computing), and likely the spiritual successor to Intel's "Skull Canyon" NUC. The first picture of the motherboard of this NUC was leaked to the web, revealing a board that's only slightly smaller than the mini-ITX form-factor.
The board draws power from an external power brick, and appears to feature two distinct VRM areas for the CPU and GPU components of the "Kaby Lake-G" MCM SoC. The board feature two DDR4 SO-DIMM slots which are populated with dual-channel memory, and an M.2 NVMe slot, holding an SSD. There are two additional SATA 6 Gb/s ports, besides a plethora of other connectivity options.

Keep in mind that the NUC boards of today at least have the CPU on the bottom of the PCB as well, which clearly isn't the case here.
jeezus, shrinking sizes with power like this oh my ......
You have to consider that you have a discrete GPU w/ HBM2 and a CPU on the same die.
It's not as much about power delivery, but supplying different voltages to various components.
Just by looking at it you can see your usual grouping:
* 4+1 for GPU
* 2 for HBM
* 1 for something
* 2 SoC (cause the entire hub is integrated into CPU die)
* 4 CPU vCore
The other coils that are scattered around the MoBo are from the power supply circuitry (12V, 5V, 5VSB, 3.3V, 1.8V etc).
The only thing that it shows, is that there is a full desktop CPU/GPU combo on that module, and not some underwhelming 15W PoS mobile CPU w/ lowest-of-the-low-end vega.
Then again, I'd be perfectly happy with a well-cooled 25W Raven Ridge - sorry, Ryzen Mobile with Vega Graphics - in the same form factor.
You listening, OEMs?
Also: no, the GPU and HBM2 are not on their own PCB on top of the substrate - the substrate links all three, with an EMIB interconnect embedded into the substrate for data transfer between the GPU and HBM. Look at the renders from the original announcement: www.anandtech.com/show/12003/intel-to-create-new-8th-generation-cpus-with-amd-radeon-graphics-with-hbm2-using-emib
Sure, these are renders, but there's no reason for them to not be relatively visually accurate, and there is no visible distinction between the CPU and GPU substrates. If i were to guess, the gold outline seen here is some sort of guide for automated chip mounting systems, if not for cooler orientation or some other reason. Another argument from Intel for this is lower Z-height, which a second substrate would ruin. Not to mention that cooler mounting and manufacture would be greatly complicated with several different heights for the chips (just look at the issues surrounding the slight variations between different AMD Vega parts, which have far lower variance than a separate substrate would infer).
And nobody has called this "integrated video". Intel specifically calls it a "discrete graphics chip".
Lastly: the reason for the distance between the CPU and GPU is in all likelihood cooling: if this is a 30-50W+ GPU, sticking it right next to the 30-45W CPU would be downright silly. It's easier to fit more heatpipes over a more spread-out area, after all, and needlessly creating difficult-to-cool hotspots is just silly.
For these to be soldered directly to the motherboard is equal to or less complex than adding another layer to the PCB and more vias.
Then again, soldering a socket to the motherboard isn't really more complex than soldering on a BGA package, as the socket itself is usually just that - a BGA package, only one consisting of a grid of pins with solder ball "feet" in a plastic frame, rather than a PCB substrate. The retention bracket on LGA sockets are probably a bit of a hassle, though. Also, BGA grids can be far more dense than any grid of pins (whether LGA or PGA), at least at the same cost/complexity.
If it is indeed the future ZBox Magnus, the PC case is going to be tall enough for a decent 95W low-profile heatsink.
