Loongson develops its first CPU with an integrated graphics card

The famous Chinese processor manufacturer Longson was the last to enter the GPU market, even though it did so in a very humble way, i.e. by developing an integrated graphics card (iGPU) with power similar to a classic graphics card launched in 2004.

Interestingly, this graph is inside the chipset Loongson 7A200 which is attached to the CPU, and we only know that it is capable of operating at a frequency between 400 and 500MHzwhich is compatible with the OpenGL 2.1 and OpenGL ES 2.0 APIs, and which allows two video outputs in the form of HDMI + VGA, being capable of displaying a resolution of 1920 x 1080 pixels @ 60 Hz or 2560 x 1440 pixels @ 30 Hz

“Recently, the new generation of Loongson 7A2000 chips, the bridge chip that supports Loongson 3 series processors, was officially launched. Compared to its predecessor, Loongson 7A2000 has an I/ S high-speed that reaches the market mainstream and has a self-developed integrated GPU, which can form a standalone display solution and significantly reduce system costs,” the company said on its website.

Regarding the performance, it is stated that in an old benchmark from 2004, like GLMark2, it is able to reach 300 FPS, while in an even older benchmark from 2000, Glxgears, it reached 1800 FPS. Of course, no matter how well you perform in games, and that’s that it’s not even compatible with the most basic functions DirectX APIso it wouldn’t even be able to run a modern Windows operating system.

The 7A200 chipset is designed to work with Loongson 3 series processors, based on the LoongArch architecture, and requires an operating system and software compatible with this architecture. Another of its specifications is to include PCI-Express 3.0 interface, SATA III @ 6 Gbps, USB 3.0, GbE PHY, UART and even GPIO. Additionally, the CPU and chipset are now connected using an interface Hyper Transport 3.1 from 32 bits to 3.2 GT/s, which implies an improvement in bandwidth 2.4 times compared to its predecessor, while SATA read and write speed improved by 82% and 97% respectively.
