Fujitsu has developed a 16-core SPARC processor for high-reliability servers.
Called SPARC64 X and made on a 28nm high-k metal-gate CMOS process, the 10th generation SPARC64 processor has three billion transistors and 13 layers of copper/low-k interconnect on a 588mm2 die.
Its 16 cores clock at 3GHz, and share 24Mbyte of level 2 (L2) cache, four 1.6GHz DDR3 ports, two PCIe Gen3 port controllers, and five 14.5Gbit/s serial ports to connect to the rest of a system.
