cpu cache explanation, faster ram than ddr5!

When talking about memory on a PC or laptop, surely you will immediately refer to RAM or hard disk or SSD. Even though besides this, there is still one more memory that is even the fastest of all.

Functions and explanations of CPU cache on the processor

Reported via video belonging to Techquickie. Whether a hard disk or SSD or RAM, actually the same concept provides data for processing by the processor. But modern processors like now, it turns out that their performance is not optimal because they often wait for data from RAM or hard disk or SSD.

For this reason there is such a thing CPU cache. The concept works similar to RAM, only the CPU cache is much faster and even exceeds DDR5. CPU cache itself is generally divided into three levels. Namely L1 cache, L2 cache and L3 cache. L1 cache is faster than L2 cache, L2 cache is faster than L3 cache. While large capacity, the opposite.

CPU cache can work very fast, because its nature is indeed different from the CPU cache DRAM (Dynamic RAM). This CPU cache can also be referred to as SRAM (Static RAM), where it does not need to refresh when saving data. But because the CPU cache is very small in size, only certain data is stored here. The rest, the data is stored in RAM and hard disk.

Then how much influence does this CPU cache have on performance such as FPS in games and others? It depends on the type of application, but in general you will definitely feel overall performance improvement. Because it is rather difficult to compare the differences between CPU caches, considering that the CPU cache is a single unit of a processor.
