modern CPU caches can predict instructions with over 95% accuracy. The L in L1, L2, and L3 stands for "Level", hinting at their hierarchical structure. The L1 cache is the fastest of the lot ...

For example an MP3 decode is more than 40% faster with a 256K L2 cache when the cache miss penalty is 144 CPU cycles. The following graphs show how the L2 cache behaves when performing a block copy.

The new AMD Ryzen 9 8945HX is still a Zen 4 gaming laptop chip, and it doesn't even increase the clock speed over its ...

[Clamchowder] explains in the post how the cache has a unique architecture ... and another one that is uncommitted. A typical CPU will have a shared L3 cache, but with so much L2 cache, IBM ...
