I'm looking at the WS76-11UM-468. Why is the GPU only listed as 16 GB when the Nvidia site lists the A5000 as 24 GB?

the Desktop one has 24GB the Low Power Mobile one Has 16GB i Will Explain it to you

the Mobile one in Laptops is 16 GB GDDR6 as it has a Memory Bus of 256 bit so has 8 x 2GB VRAM Chips to make it 16 GB (32 bits per chip)

the Desktop one is 24 GB GDDR6 as it has a Memory Bus of 384 bit so has 12 x 2GB VRAM Chips to make it 24 GB (32 bits per chip)

Mobile versions are not as powerful as a Desktop one as they massively Reduce the Power on them as there is not the Cooling (Would need to be 2 inches Thick) or Power Delivery to Power it unless you had like 3 DC power Jacks and Power Adapters that all had to be connected for it to even works that defeats it being mobile.

here is the data for each:
