I've been looking online and I can't find out what the 2nd smaller die is. Is it the iGPU?

Most likely yes.

When i ask for more specs, don't expect me to know the answer!

I think it's the other way around, the iGPU would be the bigger die.

By searching more online, it seems the smaller one is the 14nm PCH, and the larger one is the 10nm SoC.

Neither.

 

What is that supposed to be a picture of?

The larger SoC die (with iGPU)

Was asking about the OP image, sorry.

 

Found all of the info.

Larger square die is CPU+GPU.

Smaller rectangular die is the PCH.

IGPU is not on a different die on any current parts.  Older Intel parts looking like this had an external eDRAM die for cache that could be used by the IGPU or CPU cores on the CPU die.  The IGP was still on the CPU die though.  These were known by the codename crystal well AFAIK, the marketing term was Iris Pro.  Im going to go out on a limb and guess that the seccond die in that shot is eDRAM and not the GPU itself.

 

Even further back on 1st gen i7 parts the memory controller and IGP was housed on a seperate die in the CPU package, but this was 10+ years ago now.
