Who are the two main manufacturers of CPUs?

The correct answer identifies Intel and AMD as the two primary manufacturers of CPUs, which are central processing units vital for computer functionality. Intel has been a dominant player in the CPU market for decades, known for its high-performance processors used in a wide range of devices, from personal computers to servers. AMD has emerged as a strong competitor, particularly known for its Ryzen series of processors that offer competitive performance and often better price-to-performance ratios than Intel's offerings.

Both companies have a longstanding rivalry that drives innovation and advances in CPU technology, making consumers the beneficiaries of these developments through competitive pricing and improved performance features. This competition has also led to improvements in multi-core processing, integrated graphics capabilities, and energy efficiency.

The other options do not accurately reflect the leading CPU manufacturers. NVIDIA is primarily known for its graphics processing units (GPUs) and has more recently begun to produce some CPUs, but it is not one of the main CPU manufacturers. Qualcomm specializes in mobile processors, particularly for smartphones, and while it plays a significant role in that market, it does not compete at the same level as Intel and AMD in the general CPU landscape. IBM and Apple have produced CPUs in the past, particularly for niche markets or legacy systems, but do not dominate the market like
