2.2 Caching operation
Main steps:
Initial access: When the processor needs data, it first checks the L1 cache.
Hits and misses:
Cache hit: If the data is found in the cache a "hit" is like a hit, not like a piece of music, it is quickly delivered to the processor
Cache miss: If the data is not in the cache a "miss" is a miss, the processor checks the next levels of cache L2, then L3. If the data is not found at these levels, it is fetched from RAM.
Cache refresh: Data retrieved from RAM is stored egypt mobile database in the cache for future access, replacing less frequently accessed data based on replacement algorithms such as Least Recently Used LRU.
2.3 Impact on performance
Effective use of cache can have a significant impact on system performance. Access to data is much faster than access to RAM, which reduces latency and improves data processing speed. Although this is a bit of a stretch, an example would be the Ryzen 7 5800X vs 5800X3D. The X3D has a large vertical 3D cache. And as you probably know or have seencan see in benchmarks, the 5800X3D significantly outperforms applications that can use a larger cache. One explanation is that the cache implementation and its use are better.
