WebMar 25, 2024 · Basically, there are three main factors that affect CPU performance. These are the: 1. Clock Speed, 2. The Number of Cores and 3. Cache Size. Aside from those that … WebJun 3, 2009 · The small/fast caches built-in to other cores are there to speed up those cores. Sharing them directly would probably cost more power (and maybe even more transistors / die area) than other ways of increasing cache hit rate. (Power is a bigger limiting factor than transistor count or die area.

WebMar 19, 2024 · If a cache size is too small, the processor may be unable to store all of the data it needs and performance will suffer. On the other hand, if a cache size is too large, the processor may be wasting resources on unnecessary data. To optimize cache size, consider the workload and determine how much information needs to be stored in the cache.
