Which of the following statements is true about L1 cache?

L1 cache operates at the same or very close to the processor's clock speed, meaning it delivers data as fast as the processor can handle, not generally faster than the processor's fundamental clock speed.

L1 cache is the highest-level (closest to the CPU core) cache memory and is directly integrated onto the CPU die itself. This direct integration minimizes latency, allowing the processor to access frequently used data and instructions at the fastest possible speed.

While L1 cache is extremely fast, 5 nanoseconds (ns) is a relatively long latency for modern L1 cache access, which is typically measured in a few CPU cycles, often in the picosecond range (e.g., 0.25ns to 1ns per cycle for a 4GHz CPU).

L1 cache is integrated directly within the CPU chip itself, not located externally on the system board (motherboard), which is where RAM modules are typically found.
