WebSep 9, 2009 · Modern DDR3-1333 DRAM runs on 667MHz actually (DDR stands for Double-Data-Rate). Compare that to the not-unheard-of 3.3GHz of a modern CPU - already five times slower. That means that one "memory clock cycle duration" is 1.5ns (nanoseconds), compared to the 300picoseconds of the CPU. The DDR3 RAM takes some time to … Webe) (4 pts) For a memory hierarchy consists of Ll cache, L2 cache, and main memory, the access latencies are 1 clock cycle, 10 clock cycles, and 100 clock cycles, respectively. If the local cache miss rates for Ll cache and L2 cache are 3% and 50%, respectively, what is the average memory access time? WebJan 30, 2024 · In its most basic terms, the data flows from the RAM to the L3 cache, then the L2, and finally, L1. When the processor is looking for data to carry out an operation, it first tries to find it in the L1 cache. If the CPU finds it, the condition is called a cache hit. It then proceeds to find it in L2 and then L3. grasshopper clutch
