An Itanium® processor implemented in 32 nm CMOS with nine layers of Cu contains 3.1 billion transistors. The die measures 18.2 mm by 29.9 mm. The processor has eight multi-threaded cores, a ring based system interface and combined cache on the die is 50 MB. High-speed links allow for peak processor-to-processor bandwidth of up to 128 GB/s and memory bandwidth of up to 45 GB/s.
