   It isn't clear to me how the interaction of Arm Holdings and their   
   licensees works. Arm Holdings doesn't fabricate devices. Overlooking the   
   current feud, when Arm licenses its designs to Qualcomm, who is   
   responsible for the integration into a Snapdragon SoC?   
      
   The Raspberry Pi family is another example. The Pi 4 uses the Broadcom   
   BCM2711 with 4 Cortex-A72 cores at 1.5 GHZ. The Pi 5 has the BCM2712 with   
   4 Cortex-A76 cores at 2.4 GHz. The 5 is much faster but requires a better   
   power supply. Cooling is strongly suggested if you're going to push it.   
   How much of the power and performance difference is from the core design   
   and how much from Broadcom's decisions during integration.   
      
   The A78 is claimed to be better for power and performance where the   
   Cortex-X1 is the balls to the wall rework of the A78 used in the   
   Snapdragon 888 but that design also has 3 A76 cores and 4 A55 cores to   
   balance things out.   
      
   The first devices were hot little buggers which ultimately got blamed on   
   Samsung's manufacturing process versus TSMC so it seems It's not only the   
   Arm design but who fabs the device.

   In short, Arm's designs are aimed at different criteria but much of the   
   responsibility depends on what the licensees do with the designs. Bring on   
   the finger pointing.
