Core Functions of DDR4 RAM

DDR4 RAM plays a vital role in system performance by bridging the gap between the relatively slow storage drives (HDDs/SSDs) and the fast processing capabilities of the CPU. When an application is launched or a file is opened, relevant data is loaded from storage into RAM, allowing the processor to retrieve and manipulate it almost instantly. This temporary storage ensures smooth operation, reduces lag, and enhances overall system responsiveness.

Key Features and Advantages of DDR4 RAM

Latency (CAS Latency)

Latency refers to the time delay between when the memory controller requests data and when the RAM delivers it, commonly measured in clock cycles as CAS (Column Address Strobe) latency. While DDR4 typically has higher numerical latency (e.g., CL15–CL19) compared to DDR3 (e.g., CL9–CL11), this is offset by its significantly higher clock speeds and data transfer rates.

Due to faster clock cycles, the actual real-world performance impact of higher latency is minimal. The improved bandwidth and efficiency of DDR4 ensure that despite higher cycle counts, the effective response time remains competitive or superior to older generations.
