Which component is responsible for controlling the CPU and other components on the motherboard?

The chip component is responsible for controlling the CPU and other components on the motherboard. The term chipset usually refers to two main motherboard chipsets, namely: 1. Northbridge chip, which provides control of the CPU type and main frequency. Support, system cache support, etc.; 2. Southbridge chip, which provides support for I/O and support for KBC, etc.

The operating environment of this article: Windows 7 system, Dell G3 computer.

It is the chipset that is responsible for controlling communication and interaction between the CPU and other components on the motherboard.

The term chipset usually refers to the two main motherboard chipsets: Northbridge and Southbridge.

Northbridge chip:

Provides support for CPU type and main frequency, system cache support, motherboard system bus frequency, memory management (memory type, capacity and performance), graphics card slot specifications, ISA/PCI/AGP slot, ECC error correction and other support;

Southbridge chip:

Provides support for I/ O support, providing support for KBC (Keyboard Controller), RTC (Real-Time Clock Controller), USB (Universal Serial Bus), Ultra DMA/33(66) EIDE data transmission method and ACPI (Advanced Energy Management), etc. , and determine the type and number of expansion slots and the type and number of expansion interfaces;

Core upgrade of the chipset

The chipset integrates the latest designed Radeon HD4200 graphics core. Compared with the Radeon HD3200 display core used in the 780G chipset (the 780V chipset uses the Radeon HD3100 display core), it has greatly improved both in terms of specifications and technology.

Radeon HD4200 has a built-in upgraded version of the popular high-definition decoding engine UVD—UVD2.0 high-definition decoding engine, which can not only hardware decode H.264, VC-1, and MPEG with lower processor usage -2 videos, and also added a number of improved technologies.

Its newly added DVD Upscaling to HD technology can upgrade 720×480P resolution movies to 1920×1080ide resolution and reduce video blur, allowing users to get a better full HD video experience.

In addition, the dynamic light and dark contrast adjustment technology added to Radeon HD4200 can increase the light and dark contrast of the video, allowing users to enjoy a higher level of visual enjoyment. Corel WinDVD9, Cyberlink PowerDVD8 and Microsoft Windows Media Player already have support for the UVD2 hardware decoding engine, and Roxio, Nero and Arcsoft will launch relevant upgraded versions that support UVD2 in the short term.

The addition of Accelerated Video Transcoding (AVT) technology allows the integrated motherboard to complete high-speed video encoding work that was only possible on high-end workstations in the past. This is also the latest application of AMD GPGPU engineering.

This technology can provide 1080p video encoding capabilities faster than the actual playback time of the image, and supports the currently popular H.264 and MPEG-2 formats.

The software can transmit image data to the CAL core of GPGPU through the built-in AVT interface of the driver, and perform video hardware encoding calculations with the help of 40 highly parallelized stream processors. Cyberlink's PowerDirector 7 has officially supported AVT technology, and more and more encoding software will support this technology in the future.

In terms of specifications, AMD Radeon HD4200 has 40 stream processors, 8 texture addressing units, 8 texture filtering units, and 4 rasterization units.

Due to the advanced manufacturing process, the core frequency of HD4200 will be higher and it will continue to support hybrid crossfire, so the 3D performance of this integrated graphics card will be further enhanced.

In addition, this HD4200 graphics core also supports the latest DX10.1 application programming interface, allowing the integrated motherboard to correctly display the dazzling visual effects in various latest game masterpieces.
