What is a core video card

Core Graphics is a new generation of smart graphics, integrated in the intelligent processor, relying on the processor's powerful computing power and intelligent Energy efficiency adjustment design, with lower power to achieve the same outstanding graphics processing performance and smooth application experience. AMD's processor with core graphics is known as the APU (accelerating processor), and the processor of Intel's core graphics card is the SNB platform.

Overview

What is a core video card? The core graphics card is a graphics processing unit built on the same core chip as the processor. In short, it is a graphics processor that is merged with the processor core. Unlike the design of the Nehalem processor, which encapsulates both the 32nm processing core plus the 45nm graphics core, the 32nm core graphics and 32nm processors on the Sandy Bridge processor are fully integrated: the CPU and GPU regions are divided in the same wafer, Each of them undertakes the task of data processing and graphics processing. This integration design greatly reduces the processing core, graphics core, memory and memory controller data turnaround time, effectively enhance the processing efficiency and greatly reduce the chipset overall power consumption, helping to reduce the core components of the size of the notebook, one machine and other products to provide a more powerful performance, Richer multimedia capabilities and broader design space.

The core graphics card also has an independent energy control unit, as a result, as with the processing core support Rui Frequency acceleration technology, can independently accelerate or reduce frequency, and share three cache, which not only greatly shorten the graphics processing response time, greatly enhance the rendering performance, and complete 32+32 design mode to bring us lower power consumption. And this down before the cost of high, communication delay high disadvantages are resolved.

It is important to note that the core graphics card is not the same as the traditional integrated graphics card. At present, the graphics solution of notebook platform mainly has two kinds of "independence" and "integration". The former has a separate graphics core and independent video memory, can meet the complex and large graphics processing needs, and provide efficient application of the image coding; Integrated graphics core is integrated into the motherboard on a separate chip. and the dynamic sharing part of the system memory used as video memory, so can provide a simple graphics processing capabilities, as well as a more fluent coding applications. In contrast to the first two, the core video card integrates the graphics cores into the processor, further enhance the efficiency of graphics processing, and integrated graphics in the "Processor + Bridge + North Bridge (graphics core + memory control + display output)" Three chip solution to simplify to "processor (processing core + graphics core + memory control) + motherboard chip (Display output) "dual-chip mode, effectively reduce the core components of the overall power consumption, more conducive to the extension of the notebook's endurance time.

Development overview

Core graphics card with the Intel Next Generation Sandybridge processor came to us, playing an increasingly powerful graphics processing role.

At present, we are using the Smart processor, the graphics core of the 45nm process technology, the core is the use of 32nm process technology, so the two are only placed on the same substrate, not the true meaning of the package in the same core. It can complete the smooth decoding playback of high-definition video, enrich the multimedia application, so it is called HD graphics card.

However, with the development of technology, in the Intel Next Generation Intelligent Processor Sandybridge, the graphics core will adopt the advanced 32nm process technology, truly integrates with the processing core, this is the core video card. It provides efficient graphics processing performance and supports a range of advantage technologies such as graphics switching, DX10, SM4.0, OpenGL2.0, and Full HD mpeg2/h.264/vc-1 format decoding.

In addition, the Intel Smart processor unique Turbo Boost intelligent acceleration technology will also be used in the future for core graphics, it will not only improve the processor performance, but also provide the built-in graphics core dynamic overclocking capability, so the new generation of core graphics card performance will be significantly increased, Can even meet the mainstream game application needs.
