NO...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.Thus Cache memory is not main memory of computer system.--- form Wiki
The time it takes to select a block in memory.
Latency
Latency. The main latency figure is CAS Latency, also called CL Latency is the number of clock cycles that a RAM chip has to wait after being read or written, before it is ready to be read or written again. A lower latency means less time the computer has to wait before it can do another memory operation.
"CL" stands for "Column Access Strobe Latency," which refers to the time it takes for a memory module to access data within a column. "RL" stands for "Row Access Strobe Latency," which refers to the time it takes for a memory module to access data within a row. These latency values are important in determining the speed and performance of memory modules.

I think...the above Question you asked in which case ..are you focessing over Graphics or Perfomace based..., Actually Cache is the Excellent Feautre in Processor....,HIgh Availablity of Cache Improves the Perfomance... 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.
CL: (CAS Latency) or Column Address Strobe Latency is a measurement of delay of the chip's process. So the lower the CL number the lower the latency will be. So your answer is cl5.
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).
CL is the same as CAS Latency and RL is the same as RAS Latency. They both pertain to the number of clock cycles it takes to write of read a colum or row of data off a memory module. Source:CompTIAA+ Guide to Managing and Maintaining Your Pc by Jean Andrews Pg.207
CAS Latency rating.
If you shopped for RAM put into your computer to make sure your gaming is the fastest it can be, then the lower the latency the faster the RAM. Latency is the time when the memory controller starts to grab a line of code, there is a delay and when RAM sends out the line of code there is another delay. The time is takes RAM to find and send code is called latency. So when shopping find RAM with the lowest latency.
