Laptop hardware decryption: What is the difference between DDR and LPDDR? Which one is better?

When buying a laptop, many people will choose a model with large memory. After all, large memory can bring higher operating speed, smoother multitasking performance, and stronger system stability. However, there are currently two types of laptops’ memory, DDR and LPDDR. Some people may be confused about this: What is the difference between this memory? Which one is better? Today, BMAX will talk about these issues with you.

First let’s understand the concepts of both.

DDR

DDR is the abbreviation of Double Data Rate. It is a memory technology currently widely used in the computer field. It has the characteristics of high bandwidth and high transmission efficiency. Generally speaking, in one clock cycle, ordinary memory only transmits data once, while DDR memory can transmit data twice. If ordinary memory is like a single-lane highway, then DDR memory is equivalent to a two-lane highway, with each lane allowing vehicles to pass at the same time. Therefore, DDR memory can complete twice as much work as ordinary memory in the same time.

LPDDR

The full name of LPDDR is Low Power Double Data Rate. It is a new memory technology that combines low power consumption, high bandwidth and high data transmission efficiency. It is generally used in mobile devices such as tablets and laptops. LPDDR memory also has a double data rate. It can significantly reduce energy consumption and extend battery life while providing excellent performance. After continuous use for a long period of time, the mobile device can still maintain sufficient power, so it can well meet the hardware configuration requirements of the mobile device.

It can be seen that although both DDR memory and LPDDR memory are advanced memories with double data rates, there are still obvious differences in design concepts.

The design focus of DDR memory is to provide excellent performance and bandwidth. Its power consumption is higher, and it can provide higher transmission speed and bandwidth than LPDDR. It can play a better performance in applications that require high-intensity computing, such as image design, video production, and games.

The design of LPDDR memory needs to ensure that while providing sufficient performance, it can achieve lower power consumption, so that mobile devices do not need to be charged frequently, and can easily cope with long-term operation, while avoiding overheating, ensuring that thin and light mobile devices can operate stably for a long time.

The different design concepts lead to different application scopes of DDR and LPDDR. DDR memory is often configured on high-end notebook computers with strong performance, while LPDDR memory is generally equipped on thin and light notebook computers. In addition, the two are also different in assembly form. LPDDR memory usually exists in the form of onboard memory, which means it is directly soldered on the motherboard and cannot be replaced. DDR memory can be onboard memory or slot memory. If it is slot memory, it can provide convenience for performance upgrades.

So, when buying a laptop, you can make a targeted choice based on the different features of them. If you often play games, or like to create videos and design images, and have high requirements for performance, then you can choose a mid-to-high-end laptop with DDR memory. If you often go for business trip and have high requirements for battery life, then a thin and light laptop equipped with LPDDR memory is more suitable for you.
