The Z990 PCH for Nova Lake motherboards is apparently 22% smaller than Z890, despite featuring a higher power maximum power draw of up to 14W. The leaked picture of the PCH shows a 11.15 x 6.5mm die and 25 x 24mm package, but we're unsure what motherboard it actually comes from.

A couple of new add-in cards exemplify the trend of slapping AMD's Promontory 21 chipset onto a card for extra I/O expansion.
