How does cache coherency affect gaming performance?

What is cache coherency and why is it important for gaming?

Cache coherency refers to the consistency of data stored in local caches of a multi-core processor. It's crucial for gaming because it ensures that all cores have the most up-to-date data, reducing latency and improving performance.

How does it specifically impact frame rates in games?

When cache coherency is maintained, it minimizes the time the CPU spends waiting for data, which can lead to smoother frame rates. If there's a delay in data consistency, it can cause stuttering or lag.

Are there any games that are particularly affected by cache coherency issues?

Yes, games that require real-time data processing, like multiplayer online games, can suffer from cache coherency issues, leading to performance drops.

What can developers do to improve cache coherency in their games?

Developers can optimize data structures, use efficient algorithms, and leverage hardware features to enhance cache coherency, ensuring better performance.
