线性稳定电源有一个共同的特点就是它的功率器件调整管工作在线性区，靠调整管之间的电压降来稳定输出。由于调整管静态损耗大，需要安装一个很大的散热器给它散热。而且由于变压器工作在工频(50Hz)上,所以重量较大。

工作流程和物理结构大致是类似的，相比于CPU而言，GPU的工作更为单一。在大多数的个人计算机中，GPU仅仅是用来绘制图像的。

如果CPU想画一个二维图形，只需要发个指令给GPU，GPU就可以迅速计算出该图形的所有像素，并且在显示器上位置画出相应的图形。由于GPU会产生大量的热量，所以通常显卡上都会有立的散热装置。

A common feature of the linear stable power supply is that its power device adjustment tube works in the linear region and stabilizes the output by adjusting the voltage drop between the tubes. Due to the large static loss of the adjustment tube, it is necessary to install a large radiator to dissipate heat. And because the transformer works at the power frequency (50Hz), the weight is larger.

The workflow and physical structure are roughly similar, and the GPU's job is more monolithic than the CPU's. In most personal computers, Gpus are only used to draw images.

If the CPU wants to draw a two-dimensional graph, it only needs to send an instruction to the GPU, and the GPU can quickly calculate all the pixels of the graph and draw the corresponding graph on the display. Because Gpus generate a lot of heat, there is usually a cooling device on the graphics card.
