I am using a Raspberry Pi 5, which is equipped with a Cortex-A76 CPU. I would like to know the read latencies for each level of cache. For instance, the delay for an L1d cache hit may be in the range of 1-5 cycles, while the delay for a cache miss that requires reading from RAM can be several hundred nanoseconds. I would like to know where I can find this information.
Currently, I can find memory latency data for the ARM Cortex-A76 (Kryo 485 Gold Prime, 2.84 GHz) on the 7-cpu website(https://www.7-cpu.com/cpu/Cortex-A76.html), but I believe this may differ from the BCM2712 used in the Raspberry Pi.
