The processor has 5.56B transistors on a 31.9mm×20.8mm die in Intel’s high-κ metal-gate tri-gate 22nm CMOS technology [2] with 11 metal layers and achieves a 33% performance boost, on average, over previous generations [3]. Two additional metal layers enable area optimization and performance improvement. The design supports a wide range of configurations, including thermal design power ranging from 55 to 165W and frequencies ranging from 1.6 to 3.8GHz. Fig. 4.5.1 shows the processor block diagram of the 18 core die.
