The mainstream VLSI technology in the period 2004-2008 was 90 nm.
Now the industry is using 35-45 nanometer and smaller (but yield problems).
Parameters from a 90 nanometer standard cell library:
Typical processor core: 200k gates + 4 RAMs: one square millimeter.
Typical SoC chip area is 50-100 mm² → 20-40 million gates (semi-custom/standard cell).
Actual gate and transistor counts are higher owing to full-custom blocks (RAMs mainly).
