In comparison between an AMD processor and an Intel processor with the same speed rating, what factor can affect their performance?

1. Only the clock speed

2. Cache and other features

3. The brand name

4. System firmware

The correct answer is: Cache and other features

When comparing an AMD processor and an Intel processor that operate at the same clock speed, the performance differences can be attributed to various factors, with cache size and other features being particularly significant. Cache size plays a crucial role in CPU performance as it is a small amount of very fast memory located on the processor itself. The cache stores frequently accessed data and instructions, enabling the processor to retrieve this information more quickly than if it had to access the system RAM. AMD and Intel processors might have different cache architectures or sizes, which can lead to variances in how efficiently they handle tasks at the same clock speed. In addition to cache, other features such as hyper-threading, architecture design, integrated graphics capabilities, and thermal design power (TDP) can also impact overall performance. These characteristics influence how well a processor can manage simultaneous tasks, how efficiently it operates, and how well it maintains performance under load. Therefore, it's essential to consider not just the clock speed but also these additional factors to fully understand the performance differences between processors from AMD and Intel.
