Hybrid processors that can process 32 bits or 64 bits are known by what term?

Learn about x86–64 processors, also known as hybrid processors, that can process both 32-bit and 64-bit instructions. Discover their key features, benefits, and examples from Intel and AMD. Click Here to Know the Answer with Explanation

Hybrid processors that can process both 32-bit and 64-bit instructions are commonly referred to as x86–64 or x64 processors. These terms are used interchangeably to describe processors that are capable of running both 32-bit (x86) and 64-bit (x86–64) applications.

Understanding x86–64 Processors

x86–64 (also known as x64 or AMD64) is an extension of the x86 instruction set, which was originally developed for 16-bit and 32-bit processors. The x86 architecture has been the foundation for many personal computers for decades. When the need for greater computing power and larger memory addressing arose, the x86–64 architecture was developed to address these needs while maintaining compatibility with older software.

Key Features of x86–64 Processors

1. Backward Compatibility:

• x86–64 processors can run both 32-bit and 64-bit operating systems and applications. This backward compatibility is essential for users who need to run legacy software that was designed for 32-bit systems.

1. Increased Memory Addressing:

• One of the primary advantages of 64-bit processors is their ability to address significantly more memory than 32-bit processors. While a 32-bit processor can address up to 4 GB of RAM, a 64-bit processor can theoretically address up to 18.4 million TB of RAM, though practical limitations are much lower.

1. Enhanced Performance:

• 64-bit processors can handle larger data sizes and more complex calculations, leading to better performance in tasks such as video editing, gaming, and scientific computing.

1. Larger Registers:

• x86–64 processors have larger general-purpose registers, which allows for more efficient processing of data and improved performance in certain applications.

Examples of x86–64 Processors

• Intel: Intel’s line of x86–64 processors includes the Core series (i3, i5, i7, i9), Xeon, and Pentium processors. These processors are widely used in desktops, laptops, and servers.
• AMD: AMD’s x86–64 processors include the Ryzen series, EPYC, and Athlon processors. AMD was the first to introduce the x86–64 architecture with their AMD64 processors.
