The GPU is the "heart" of the graphics card, which is equivalent to the role of the CPU in the computer. It determines the grade and most of the performance of the graphics card, and it is also the difference between 2D and 3D graphics cards. 2D display chips mainly rely on the CPU's processing power when processing 3D images and special effects, known as "soft acceleration". The 3D display chip is the three-dimensional image and the special effects processing function is concentrated in the display chip, which is the so-called "hardware acceleration" function. The display chip is usually the largest chip (and the one with the most pins) on the display card. The GPU makes the graphics card less dependent on the CPU and does some of the work of the CPU, especially in 3D graphics processing. The core technologies used by GPU include hardware T&l, cubic environment material mapping and vertex mixing, texture compression and bump mapping, dual texture

  CPU   Generally speaking, the CPU computing power is the weakest, although the CPU has the highest main frequency, but the single is also 8 cores, 16 cores, a core of 3.5g, 16 cores is 56g, and then consider the instruction cycle, up to 30g times per second multiplication. Still fixed point.   D SP   Although the main frequency of the DSP is not as good as the CPU, but the multiplier is more, casually with 16 multipliers, or floating point. And then a 4 cores, 8 cores, and specific algorithms hardware acceleration, so although the main frequency is only 1,2g but the computing power is still stronger than the CPU. Of course, now there is a CPU with a dedicated multiplier, DSP also set the ARM core, the boundary between the two began to blur.   All DSP calculations use floating point algorithms, and there are no bit or integer instructions yet.   GPU   GPU is designed for image processing, the main frequency is generally around 500mhz, but there are many cores, such as titan, there are

As almost everyone who knows anything about hardware will know, the CPU is a square, thick piece of metal, although there are also rectangular versions. The top surface is flat and smooth, while the bottom surface has metal contacts or pins. Although the default shape of a CPU is rectangular, I wonder if you have ever wondered why CPUs are not made round? 1. The CPU we see is not a real CPU Before answering this question, I would like to explain that the small piece of metal we can see with our eyes and feel with our hands is not the CPU but its package, the CPU chip is firmly mounted in the center of the package. It is no coincidence that the CPU chip is also rectangular, so let's talk about why the real CPU chip is in this shape. 2. Let's start with manufacturing Many students may know that the CPU chip is made of sand, I do not know if this knowledge has the credit of the science that Lei wants to sell mobile phone chips at the price of sand in it. The composition of the san
