内存两个8g和1个16g有什么区别(内存4个8g好还是2个16g好)

Is there a difference between two 8 memory modules and one 16g memory module? Two 8-channel memory modules are dual-channel and one 16g memory module is single-channel. The difference is in the following three aspects:

Difference 1. Different concepts

1. Dual-channel memory refers to A memory method that uses two memories of the same brand and the same specification and capacity. Generally speaking, dual-channel means that two memory controllers control two memories respectively. It is theoretically better than single-channel, so it has been widely used.

2. Single-channel memory can only be read or written at the same time. Just like the entrance and exit of a parking lot, only one car can pass in and out at the same time. When the traffic flow is small, it doesn't matter. But when there are more than 100 cars, they will wait for each other.

Difference 2. Different reading speeds

Single-channel memory can only read or write at the same time; dual-channel memory refers to Memory reading and writing use different channels, which can read and write at the same time, doubling the memory bandwidth. Due to the dual-channel memory structure, overclocking is difficult. For users who like DIY, overclocking also has certain limitations.

Difference 3. Different processing capabilities

Dual-channel has advantages over single-channel in terms of reading and writing. In daily opening of software or documents, it is definitely faster than single-channel. . For example, when running some large games, it is a bit difficult due to memory bandwidth issues, and the performance improvement of dual channels can be clearly felt.
