Cache memory consists of different levels called L1, L2, ... It is usually 64 KB per core, so that a quad-core CPU, for example, has a total of 256 KB. A CPU usually has three cache memory levels.

Many people have heard the term cache coherency without fully understanding the considerations in the context of system-on-chip (SoC) devices, especially those using a network-on-chip (NoC). To ...

Cache memory is a vital part of a PC's performance and efficiency. However, you can't directly control how much cache you'll have available, and are only able to clear it when it gets too full.

For example, in the scenario illustrated in Figure 1b, suppose CPU0 retrieves and modifies data from the main memory and then stores the altered version in its L1 cache. Now, imagine that CPU3 ...

Once a device caches a memory location, it can implement any advanced semantics since it’s guaranteed to be performed atomically within the 64-byte cache line boundary. Another example is ...

So let's see how memory scaling differs between Zen 4 and Zen 4 3D V-Cache in today's games. For all of the testing, we used a GeForce GTX 4090 at 1080p, Windows 11, and Resizable BAR was enabled.

Write-back caches improve performance, because writing to the cache is faster than writing to main memory or disk. Disk Writes. A disk write-back cache does add a slight amount of risk, ...
