Intel states that its next-generation processors no longer use lead as raw material, and it is expected to stop using halogens by 2008. Through these measures, Intel processors will greatly reduce the harm to the environment. It can effectively solve the problem of electrical leakage and increase the power consumption efficiency of the processor by 30%. As the size of transistors continues to shrink, the electrical leakage is also more serious, leading to the problem of processor heating and excessive functions. In a way, electrical leakage has become a bottleneck that hinders further improvement in processor performance. The most appropriate summary of the main meaning of this passage? ['Intel Corporation has successfully developed new technologies to address the issue of electrical leakage.', 'Electrical leakage is a bottleneck that needs to be resolved in the processor production process.', 'As the size of transistors continues to shrink, the heat and power consumption of processors will become more and more serious.', "Intel's next-generation processors use new materials, which is not only more environmentally friendly, but also increases power."]
