Agreed these counts look high - but the fact that they can slot this into a $3,499 laptop is remarkable and must say something about the cost effectiveness of TSMC 5nm process.
The CPU may not have a 32 core GPU inside it but that doesn't stop you from adding the 2 numbers together and seeing it's still significantly less than 57 billion.
Would be very curious to see what took all of the die space. Neural engine? Those additional video encoding engines? I doubt we'll get to know unfortunately.
