This may be why the idea of 'low latency' seems so counter-intuitive. When the memory controller tells the memory to access a particular location, the data must go through a number of clock cycles in the Column Address Strobe (CAS) to get to its desired location and complete the command. If you're interested in how much memory your computer should have, Many users believe CAS latency is an accurate indicator of real world latency performance, Many users also believe that because CAS latencies increase with speed gains, some of the speed gets nullified, Semiconductor engineers know that CAS latencies are an inaccurate indicator of performance, Latency is best measured in nanoseconds, which is a combination of speed and CAS latency, Both speed increases and latency decreases result in better system performance, Example: because the latency in nanoseconds for DDR4-2400 CL17 and DDR4-2666 CL19 is roughly the same, the higher speed DDR4-2666 RAM will provide better performance, Example: if the speed rating of a standard module and a gaming module is the same (i.e. These CPU processes could easily drive times up to milliseconds, he said. A lower-memory nanosecond specification means the computer can access its memory faster and generally operate at a higher speed to produce its output. An arrow goes from the laptop to a server, and is labeled as "30 ms". Could a subterranean river or aquifer generate enough continuous momentum to power a waterwheel for the purpose of producing electricity? You can find information about RAM frequency and CL timing on labels stuck on RAMs or the product page for RAM on any ecommerce store where you buy RAMs. The higher the clock speed, the more operations the CPU can execute per second. Time is defined as the period over which events occur. The computer clock speed is normally calculated in gigahertz (GHz) or megahertz (MHz). We also measure bit rate in smaller units like kilobits (, Ever heard the term "broadband Internet"? By optimizing the balance between the maximum speed your processor is capable of and the lowest latency memory available within your budget, you are able to achieve a higher level of performance using newer, faster, and more efficient memory.
