It is fabricated in 32nm 10 Cu-layer high-κ metal-gate (HKMG) low-power bulk CMOS, and contains 1.14 billion transistors within 182.5mm2 die area. Through numerous design improvements, Godson-3B1500 is able to support a wide voltage range from 1.0V to 1.3V, at frequencies ranging from 1.0GHz to 1.5GHz, achieving 172.8GFLOPS at 1.35GHz, with nearly 40W power dissipation. This represents a 35% power-efficiency improvement over the previous design, Godson-3B [1]. Godson-3B1500 maintains a two-node eight-core architecture with an enhanced GS464V core (which is MIPS64-compatible with vector extensions) [2].
