Intel details Iris Xe Max dGPU for Tiger Lake laptops — no SLI-esque features for gaming but Deep Link with Xe iGPU for content creation and AI – Notebookcheck.net

Unfortunately, Intel didn’t delve too deep into how this technology works. For instance, we didn’t get much information on how Dynamic Power Share is different from similar implementations from NVIDIA and AMD. We also didn’t get any confirmation on the laptop’s TDP configuration to properly utilize this feature. However, we could arrive at a few speculative inferences.

Remember the Tiger Lake naming conundrum in which we pointed out how a Core i7-1185G7 can supposedly be configured by OEMs to actually perform worse than a Core i7-1165G7? Though Intel wasn’t explicit in detailing this, it appears that an Xe Max laptop does mean a Tiger Lake chip configurations with at least 28 W cTDP.

We, however, did get an indication that Xe Max will be part of “35 W-class” Tiger Lake laptops. In fact, Intel’s test system specifications (see slide below) indicate that the Swift 3X with a Core i7-1165G7 was running at a PL1 of 30 W. Our speculation is that the added 2 W headroom is for the Xe Max. So, in a 35 W system, 28 W could be for the Tiger Lake package and 7 W for the Xe Max dGPU.

It is likely that a majority of the power is allocated to the Tiger Lake package and then shared intelligently with Xe Max via Dynamic Power Share. This not only helps OEMs design better cooling but also prevents unnecessary power loss on battery. Again, this is our takeaway from discussions with Intel. Hopefully, we will get to know the full picture once we get our hands on Xe Max-powered Tiger Lake notebooks.
