The GPU is powered by DDR4 memory at 2.0 – 2.4 GHz and has a maximum capacity of 16GB.The highest support dual-screen display, the basic resolution is [email protected]， Highest support [email protected]. As for performance, glmark2 achieves over 300 FPS, and glxgears can exceed 1800 FPS, which is no problem to meet desktop office needs.
In addition, Loongson 7A2000 integrates PCIe 3.0, SATA 3.0, USB 3.0 / 2.0, Gigabit PHY, HDMI, I2C, UART, GPIO and other interfaces to provide rich north-south bridge functions for the processor. The display interface is upgraded to dual HDMI and single VGA, which can be directly connected to the display, and the built-in network PHY physical layer can directly provide network output.
With the Loongson 3A5000 processor of Loongson 7A2000, its read and write performance and transmission speed have been significantly improved again:
- HyperTransport frequency up to 3.2 GHz, DDR4 memory frequency up to 2,400 MHz
- Compared with the previous generation Loongson 7A1000, the SATA read performance is increased by 82%, the write performance is increased by 97%, and the PCIe performance is increased by 1.4 times
