Overview
Mars II is Phytium's second-generation many-core server processor based on a custom ARM core. The Mars II is largely a shrink of their first-generation SoC but it does introduce a number of enhancements. Fabricated on a leading-edge 16 nm FinFET process, the new SoC is considerably smaller than the prior die, offers higher frequency, and lower power. Mars II features 64 custom ARMv8.0 cores operating at up to 2.3 GHz for a total of 588.8 GFLOPS. The SoC incorporates high DDR4-2400 memory channels and includes 33 PCIe Gen 3.0 lanes.
