The primary difference between a 32-bit and a 64-bit CPU architecture lies in the amount of data they can process and the memory they can address. A 64-bit architecture can process larger amounts of data more efficiently than a 32-bit architecture because it allows for a wider data bus, which means it can handle more bits of data at once. Specifically, a 64-bit CPU can directly address significantly more RAM—up to 16 exabytes theoretically, though operating systems often have physical limits much lower than this. In practice, many modern applications and operating systems are designed to take advantage of 64-bit architecture to enhance performance, especially when dealing with large data sets.

The larger register size also allows 64-bit CPUs to improve the performance of certain calculations and operations, particularly those involving high-performance computing, gaming, and large databases, as they can process more data with each cycle compared to their 32-bit counterparts. This efficiency can lead to better multitasking capabilities, improved performance in memory-intensive applications, and an overall smoother user experience.

In the context of the other choices, a 32-bit architecture does not inherently handle processes more slowly (although the limitations on memory can lead to performance issues in RAM-intensive situations), it supports less RAM
