The cover letter from Nicolas includes:

0x7 is three bits set, so it certainly looks like there are 3 shader
cores. Of course I wouldn't guarantee that it is as simple as each power
domain has a shader core in. The job manager and tiler also need to be
powered somehow, so they are either sharing with a shader core or
there's something more complex going on.
