This behemothic Itanium packs 2.06 billion transistors onto one die – a record for a processor – and consumes an equally Brobdingnabian 170 watts. Each of the four cores has 104 million transistors and takes around 25 watts, while the system interface and input/output accounts for 200 million and 50 watts. The lion's share of the remaining component budget goes into the 1.420 billion transistor L3 cache, although that only takes 20 watts in operation.
