Here's a really haphazard try. I probably got a lot of stuff wrong, but I'm excited to see what others come up with:

some labels on SKX

Some questionable things:
  • Is the block of SRAM to the left the L1i, or the BTB? And if it's the BTB, part of what I labeled the uop cache would be the icache (had a discussion with someone on discord and they thought that might be the case)

  • There's a lot of buffers in the fetch portion of the chip. That can't just be for the fetch queue and IDQ.

  • Can't find the decoders. Can't imagine what they'd look like.
