I checked the available information, but I couldn't determine if the second smallest die is the iGPU.
I believe the opposite is true; the iGPU would be the larger component.
The picture depicts a component belonging to a system. I was checking the original post image, sorry about that. All relevant details were gathered from the source page: https://en.wikichip.org/wiki/intel/micro...e_(client). A bigger die contains the CPU and GPU, while a smaller rectangular die houses the PCH. The IGPU isn’t on its own die in any current Intel parts. Earlier Intel designs featured an external eDRAM cache that could serve either the IGPU or CPU cores on the main die. The IGPU remained on the CPU die itself. These units were previously known by the codename "Crystal Well," and the marketing name was "Iris Pro." I’m leaning to believe the second die in that photo is eDRAM, not the GPU directly. Going back further, on earlier 1st generation i7 models, the memory controller and IGPU were placed on a separate die within the CPU package—something that has changed significantly over time.
