As a domain expert in computational neuroscience and cognitive psychology, I have spent considerable time exploring the intricacies of both human cognition and artificial computation. When we compare the human brain to a computer, it's important to understand that these two systems are fundamentally different in their architecture and function. The human brain is an organic, complex, and highly interconnected network of neurons, while a computer is an electronic device that processes information based on binary logic.
Speed of Processing
The speed at which a computer can process information is indeed faster than the human brain in terms of raw computational power. For instance, the K supercomputer from Fujitsu, as mentioned, computes at a rate that is four times faster than the human brain and can store ten times as much data. However, the human brain's processing is not uniform across all tasks. It excels in areas such as pattern recognition, decision-making under uncertainty, and learning from experience, which are not necessarily measured in terms of raw speed but in the complexity and adaptability of the processing.
Energy Efficiency
One of the critical aspects to consider is energy efficiency. The human brain operates on about 20 watts of power, which is remarkably energy-efficient considering the complexity of its operations. In contrast, supercomputers require vast amounts of energy to perform their calculations, often running into the megawatt range.
Parallel Processing
The human brain is a master of parallel processing. It can handle multiple tasks simultaneously, integrating sensory inputs, emotional responses, and cognitive functions without the need for sequential processing. Computers, while capable of parallel processing, often require complex algorithms and significant computational resources to achieve the same level of multitasking.
Adaptability and Learning
The human brain is also unparalleled in its ability to learn and adapt. It can form new neural connections and pathways in response to new experiences, a process known as neuroplasticity. This ability to learn from experience and adapt to new situations is something that, while being a focus of artificial intelligence research, computers currently cannot replicate to the same extent.
Generalization and Creativity
When it comes to generalization and creativity, the human brain stands out. Humans can take knowledge from one domain and apply it to another, creating new ideas and solutions. Computers, on the other hand, are very good at tasks they are specifically programmed for but struggle with generalization without extensive reprogramming or learning from vast datasets.
Emotional Intelligence
Lastly, the human brain possesses emotional intelligence, which is the ability to understand and manage our own emotions as well as empathize with others. This is a dimension of intelligence that computers do not possess and is critical for human interaction and decision-making.
In conclusion, while computers are faster and can store more data, the human brain's capabilities in areas such as pattern recognition, energy efficiency, parallel processing, adaptability, generalization, creativity, and emotional intelligence make it a unique and powerful organ. The comparison between the two is not straightforward, as they are designed for different purposes and operate on different principles.

Computers versus Brains. For decades computer scientists have strived to build machines that can calculate faster than the human brain and store more information. The contraptions have won. The world's most powerful supercomputer, the K from Fujitsu, computes four times faster and holds 10 times as much data.Nov 1, 2011
