What Is RAM Speed?

When it comes to RAM speed, there are several factors to consider. Let’s clarify these terms and understand their impact. The performance of your system RAM depends on various elements, including frequency, bandwidth, total number of channels, quantity, dual data rate (DDR), latency, and even the speed/gen of your processor.

When people talk about “RAM speed,” they usually refer to the frequency of the RAM, which represents the number of commands it can process per second. For the purpose of this discussion, we’ll focus on frequency. RAM frequency is measured in MHz and is typically mentioned right after the DDR version in the RAM specifications. For example, if you have 8GB DDR4-2400 RAM, it operates at a frequency of 2400MHz. RAM frequencies can range from 800MHz in older DDR2 modules to 6800MHz in DDR5.

It’s crucial to remember that system RAM doesn’t handle command processes like the CPU does. While a higher CPU frequency generally leads to better PC performance, the same cannot always be said for high-frequency RAM. Therefore, even though higher frequency RAM is technically faster, that extra speed often doesn’t translate into improved real-world performance.

By understanding the nuances of RAM speed and its various factors, you can make informed decisions when choosing RAM modules for your system. Keep in mind that overall system performance relies on a combination of factors, including CPU, RAM, and other hardware components.
