Well well well, I have something really interesting for you. Remember the Xe HP GPU leak from a couple of days back that showcased a 4-tile 500W GPU? And remember how most people assumed this is a 512 EU affair with 4096 cores? Well, I decided to ask one of my sources working at Intel and they told me the exact ratio and its not 128 EU per tile. The distinction, it seems, lies in between Xe LP and Xe HP - and the documents leaked were about Xe HP.

Let's start by setting the record straight about something. The original leak by Digital Trends assumed a number of 128 EUs per tile. The problem is they were talking about Xe LP which is not the same thing as Xe HP. While the former is designed as a low power/performance platform and internally referred to as Xe 12.1, the latter is a high power/high-performance platform internally referred to as Xe 12.5. The EU count per-tile of Xe 12.5 or Xe HP is actually different. Xe HP actually has an EU count of 512 EUs per tile.
