Overview of CPU specs: Cache size and power efficiency

“

- [Instructor] For the cache size, the CPU cache memory is a small, extremely fast memory used by the CPU to store and quickly access frequently-used data, usually measured in kilobytes or megabytes. If the CPU were to fetch every instruction or piece of data directly from the memory, it would spend a lot of time waiting. So cache memory can temporarily store the data needed by the CPU to increase the speed of data retrieval. Using the same examples, the cache size of this Intel CPU unit is 24 megabyte. And for the AMD Ryzen 9 CPU, it's showing the cache memory size for each level. I will cover more about it in the cache memory video later in this course. In general, larger cache sizes can contribute to better CPU performance, particularly in task that require large amount of data to be repeatedly accessed. However, larger cache sizes can sometimes introduce slightly more latency, meaning it might take longer time to…
