The Level 3 (L3) cache has the highest latency. The CPU cache is memory that is used to decrease the time that it takes the CPU to access data. Because the data is cached, it can be accessed more quickly. The CPU cache is often found directly on the CPU or built into the CPU. The L3 cache is usually larger than the L1 and L2 cache, but it is searched last. The CPU searches for data in the following order: L1 cache, L2 cache, L3 cache, RAM.

What is miss latency?
miss latency is the time (in cycles) the CPU waits when a miss happen in the cache. (the time needed to bring the data from the main memory to the cache).
What type of memory stores frequently used instructions or data needed by the CPU?
the memory that directly communicates with the CPU is called Cache Memory this is; When the processor(CPU) needs to read from or write to a location in main memory, it first checks whether a copy of that data is in the cache. If so, the processor immediately reads from or writes to the cache, which is much faster than reading from or writing to main memory. A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.

When evaluating CPU memory do you check the cache memory?
The only memory on the CPU is cache memory and it is only dependent on the CPU type and generation you use.
What are the type of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
Is cache on a CPU?
CPUs do have a cache (either L1, L2 or L3), but cache is not exclusively on the CPU.
Where the the L1 cache located?
L3 cache is located on the motherboard or in CPU housing.Hope this help.
What type of CPU cache memory may be found on the motherboard or along side the CPU core?
probably SDRAM
What do you know about cache?
cache is the type of memory within the CPU. It is extremely fast and is very small storage wise (it only comes in megabytes)
What is the relationship between a computer's CPU speed CPU cache and it's main bus speed with regard to the computer's performance?
For bulk memory-to-memory copy, the main bus bandwidth will dominate, and the other components must be able to keep up (to saturate the bus and the storage components behind it). For single-byte random reads, latency will dominate. We want read requests put on the main bus to be satisfied with low latency, but inevitably several CPU cycles will go past (stalls will happen) before the request is satisfied. A larger cache may be able to reduce the number of such requests, but the cache hit ratio is very very sensitive to the application workload, and in the worst case we will see a low cache hit ratio with extra latency while we suffer the expense of a large cache.
What is the function of CPU cache?
Many CPUs have what is known as a CPU cache. The function of this CPU cache is to speed up access to data.
What was the first Intel CPU to contain an external cache?
The first Intel CPU to feature external cache was the Intel Pentium Pro. External cache is also referred to as L2 cache, while internal cache is called L1 cache.
What is the objective of cache only memory architecture?
Cache memory is the high speed memories which are repeatedly requested by the Cache client (CPU). Whenever the requested data from the cpu is present in the cache, it directly supply the data and is known as cache hit(fast) and when the data is not accessible in cache then cache access the block of the main memory and feed to the CPU and it is termed as cache miss (slow).
