> We proceed with our series of articles devoted to analyzing performance of modern CPUs in real applications and finding out the effect of processor features. However it requires an OS (Programing) link to do so. This allows the CPU to access the files at top speed constantly, without having to wait on other components to refresh, which would force the CPU to idle or seek out the information in slower types of storage. To put it simply, CPU's were getting faster, but memory wasn't. Cache performance measurement has become important in recent times where the speed gap between the memory performance and the processor performance is increasing exponentially. More recently, the L2 cache was moved from the processor packaging to the CPU die itself. The clock cycle is the time between the two electrical pulses of an oscillator. This RAM stores data which has been repeatedly used by the processor and it does not require a request from the system memory. While there are a lot of different types of storage, like DRAM (which is the system RAM), or the classic HDD or SSD memory, modern processors are getting gradually faster, requiring faster memory to prevent them from getting bottlenecked (when a system is imbalanced due to incompatibility between components). Disk cache - hard drives have some amount of cache to speed up data handling, both for read and write data. © How Does the Cache size Affect the CPU Performance? Higher-end CPUs will have more, lower end CPUs will have less. CPU-resident cache is called Level-1 (L1)cache.External cache is called Level-2 (L2) cache.
