WebMar 2, 2024 · Other cache layers can be larger and run at slower clocks, but this requires the CPU to wait until the cache answers. The GPU approach is to have lots of threads per core (i.e. a SMT factor of 16 or larger, compared with 2 on Intel CPUs or 4 on POWER). This means that each individual thread will only run at a fraction of the clock speed, but ... Cache hierarchy, or multi-level caches, refers to a memory architecture that uses a hierarchy of memory stores based on varying access speeds to cache data.
