All of the greatest CPUs and GPU chips now available are silicon-based, but researchers are aware of their limits. There is a lot of research being done to develop a successor for silicon since it is necessary to maintain scaling up performance without sacrificing power efficiency.
Graphene may be one of these options, as it has the ability to perform 10 times better than silicon while using less electricity. The issue is that it is quite expensive to produce.
According to Wccftech, a number of businesses have discussed replacing silicon-based circuits with graphene. The China Graphene Copper Innovation was developed during the China International Graphene Innovation Conference, and it appears that something may really materialize from these graphene-related ambitions for the first time in a long time.
Graphene might undoubtedly be superior to silicon, despite silicon’s current popularity because to its high yields and affordable production costs. It is supposedly 200 times stronger than steel and significantly stronger than silicon. Despite this, it is quite light. Graphene weights less than a milligram per square meter. It might take the place of copper in these cutting-edge chips because it is also very conducive in terms of thermals and electricity.
The IBM Corporation first unveiled graphene wafers in 2010, thus graphene research has been ongoing for a while. The processors at the time displayed transistor rates of up to 100GHz, although IBM claimed that they might scale up to 1000GHz. Despite this, graphene has never been adopted for mass production; the reason is the expense of manufacture.
Even while silicon-based circuits may be reaching their technological limits, they are still quite common and significantly more affordable to produce. It’s difficult to predict whether and when graphene-based circuits will go into mass manufacturing on a level that may have an impact because they are far more difficult to build. Additionally, researchers are looking into more bizarre avenues, including producing printed circuit boards out of paper or creating chips out of honey (PCBs).
