The reason that CPU chips are becoming hotter than before
As we all know, today's semiconductor chips basically bring a lot of heat when working, so it is necessary to use a heatsink to dissipate heat. So the question is, how does the heatsink dissipate the heat brought by the CPU chip? Apply a layer of thermal grease on the chip, and then install the heatsink. The thermal grease transfers the heat on the surface of the CPU to the bottom of the heatsink, and then the heat is transferred to the fins by the heat pipe or liquid cooling pipe. Finally, the fan blows away the heat on the fins or cold exhaust, which is the process of cooling.
In the future, the heat generation by semiconductor chips will be more serious, and new thermal designs closer to the "heat source" need to be used. So the question is, why will the chip fever become more and more serious in the future?
Chip design and semiconductor process bottlenecks:
Whether from the product design ideas, power consumption data, or from the real energy efficiency ratio test results, today's entire consumer electronics chip industry has actually entered a situation of "significantly improved performance, but also rapidly increased power consumption".
And the increasing power consumption may not only happen in the field of PC CPU chip,but also in graphics cards. The performance improvement of graphics cards in recent years is basically realized by stacking more cores and pulling higher frequencies, but they are retreating in the design of transistor structure and computing architecture at the bottom.
Software changes lead to increased power consumption:
Take anti-virus software as an example. Nowadays, Defender anti-virus software integrated with windows will not only consume the computing power of CPU, but also use the general computing power of graphics card to speed up the scanning process; For another example, chrome, which now occupies the absolute mainstream position in the browser industry, is actually a software that consumes a lot of memory and CPU, but no one can deny that the design with high hardware occupation does make its rendering speed and page loading speed much faster than other competitors.
In addition, in terms of office software, office has used GPU for font rendering and interface acceleration since the version several years ago, which is why many people feel that office software is not small, but the interface fluency is faster than many lightweight office software.
In other words, whether in hardware or software, the whole PC industry is actually showing a general trend of "power consumption for performance". Although environmentalists may think this is a very bad situation, users who benefit from this sharp increase in performance may not feel uncomfortable with this increase in power consumption and heating. Therefore, thermal solutions will always be a key point in cpu chip cooling design with the performance increase.
