It is not difficult to see from the naming that this notebook is equipped with the domestic Loongson. The Loongson 3A4000 chip, which is based on the new generation processor core (code-named GS464V), has a performance improvement of 100% compared to the previous generation Loongson 3A3000.
According to the actual test results of the CPU performance test tool SPEC CPU2006, the fixed-point and floating-point single-core scores of the Loongson 3A4000 both exceed 20 points, and the Unixbench four-thread score based on the Loongson 3A4000 and the latest version of the domestic operating system has reached more than 2700 points. In order to protect data security, Loongson 3A4000 integrates vulnerability prevention design, hardware national secret algorithm, secure trusted module and secure access control mechanism, which truly guarantees safe use from the bottom source of the chip.
