    The OP's youtube video posting has links to articles that highlight AMD in their title and text:

    New Intel Core Processor Combines High-Performance CPU with Custom Discrete Graphics from AMD to Enable Sleeker, Thinner Devices
    https://newsroom.intel.com/editoria...nce-cpu-discrete-graphics-sleek-thin-devices/

    "...The new product, which will be part of our 8th Gen Intel Core family, brings together our high-performing Intel Core H-series processor, second generation High Bandwidth Memory (HBM2) and a custom-to-Intel third-party discrete graphics chip from AMD’s Radeon Technologies Group* – all in a single processor package.

    It’s a prime example of hardware and software innovations intersecting to create something amazing that fills a unique market gap. Helping to deliver on our vision for this new class of product, we worked with the team at AMD’s Radeon Technologies Group. In close collaboration, we designed a new semi-custom graphics chip, which means this is also a great example of how we can compete and work together, ultimately delivering innovation that is good for consumers."
    ...
    "**“Our collaboration with Intel expands the installed base for AMD Radeon GPUs and brings to market a differentiated solution for high-performance graphics,” said Scott Herkelman, vice president and general manager, AMD Radeon Technologies Group. “Together we are offering gamers and content creators the opportunity to have a thinner-and-lighter PC capable of delivering discrete performance-tier graphics experiences in AAA games and content creation applications. This new semi-custom GPU puts the performance and capabilities of Radeon graphics into the hands of an expanded set of enthusiasts who want the best visual experience possible.”"

    At :37 "in this case the custom built Radeon mobile graphics processor".

    Ya gotta love Intel, here's what they say about the AMD and Radeon copyrighted material used in that video:

    "Other names and brands may be claimed as the property of others."

    Intel doesn't mention amd in the copyright area....JPG

    AMD's performance per watt is pretty poor. This seems.. questionable..

    On what is this based?
    AMD's GPU's are clocked on lower frequencies than Nvidia and are built on a manuf. process not suited for high clocks (in addition to being overvolted from factory) while still delivering same or better performance.
    Power draw as I said is down to the GPU's being overvolted and clocked too high for the 14nm GLOFO process. There's a chance 12nm LP process that they will use will be more suited for higher clocks though... at which point AMD might be able to clock as high as Nvidia while consuming same amount of power as Nvidia counterparts... or less.

    If the mobile components are appropriately clocked, there's no reason to thing the mobile GPU will have low performance per watt. Plus, this seems to be based on Vega igp, and possibly the version that has infinity fabric optimized for gaming.

    I was just remembering power draw of Vega 64 vs a 1080 where Vega used much more power for practically the same performance. I don't see why that wouldn't translate to mid-tier level.

    If accurate this chip is way more powerful than I expected:

    "Both are expected to features quad-core Intel processors based on the company’s Kaby Lake architecture paired with a custom AMD Radeon graphics processor with 24 compute units and 1536 stream processors. The result is two processors that should be able to outperform any Intel mobile chips with integrated Intel HD graphics… but which should (at least theoretically) consume less power than a typical laptop with an Intel processor and discrete graphics."

    It appears this iGPU will be somewhere between the GT 1030 and GTX 1050. I'm still surprised that they managed to pack so many SP's in.

    But that's not because of the architecture itself... its mainly down to the manuf. process limitations and voltages.
    Also bear in mind that AMD has more stream processors on their GPU's vs CUDA cores - which only add to the power draw.
    Plus, when Vega is set to similar voltages like Nvidia's counterparts without touching the clocks, their power draw does reduce to similar/same level - and of course there's the fact that an undervolted Vega 56 which is also overclocked on the core and HBM ends up performing like GTX 1080 while drawing less power than 1080.

    So, again, it's not Vega's architecture to blame here... its the manuf. process.
    I wonder what would have happened in AMD used same TSMC 16nm process for Vega... clocked it as high as Nvidia did their chips (along with increasing the HBM frequency) and operated on similar/same voltages.
    I would imagine that we could see a much better performance per watt ratio.

    The 12nm LP process for Vega and Ryzen refresh could bring that about (along with supposedly optimized for gaming infinity fabric on Vega)...

    TSMC 16nm process vs Glofo 14nm process is no contest in favor for TSMC because its designed for high performing parts... Glofo process is designed for low performing parts (plus there's the additional problem of necessary gpu yields on that process - which is why it was mentioned AMD might go to TSMC for 7nm Navi) - and of course, AMD would be incurring monetary loss as a result of switching fabs.
