For comparing DDR3 and DDR4, just first see what is RAM, RAM is the memory of a computer that can be read and changed at any time. The information stored in this type of Memory is lost when the power supply to the PC or laptop is switched off. For comparing DDR3 and DDR4, It is known as the main Memory or temporary Memory or cache Memory or volatile Memory of the computer system. The full form of RAM is Random Access Memory. For comparing DDR3 and DDR4, this article will help you the most.

DDR3

DDR3 RAM is similar to DDR2 RAM, but uses roughly 30% less power and can transfer data twice as fast. While DDR2 memory can transfer data at up to 3200 mbps (megabytes per second), DDR3 memory supports maximum data transfer rates of 6400 mbps. Therefore, if two computers have the same processor clock speed, but different types of memory, the computer with DDR3 memory may perform faster than the computer with DDR2 memory. This prevents the RAM chip from being installed in a slot that does not support DDR3 RAM. Therefore, when upgrading your computer’s memory, make sure you get the appropriate type of memory for your computer. This means computers with DDR3 memory can transfer data to and from the CPU much faster than systems with DDR2 RAM. The faster memory speed prevents bottlenecks, especially when processing large amounts of data.

DDR4

DDR4 DIMMs are the first to have a curved bottom edge, which makes it easier to insert them into and remove them from RAM slots on a motherboard. DDR4 memory modules come in two primary form factors — DIMMs and SO-DIMMs. DIMMs are commonly generally used for desktop towers, while smaller SO-DIMMs are designed for laptops and all-in-one desktop computers. DDR4 is designed to replace DDR3, the previous DDR standard. Advantages include faster data transfer rate and larger capacities, thanks to greater memory density and more memory banks (16 rather than 8). DDR4 also operates at a lower voltage (1.2V compared to 1.5V), so it is more power-efficient. This prevents the memory from being a bottleneck as processing speeds and bus speeds increase. Faster speeds and increased memory bandwidth allow DDR4 SDRAM to keep up with modern processors, including multi-core CPUs.

Difference Between DDR3 and DDR4

Key Points in Brief

So if we talk about DDR3 and DDR4, we can see that they doesn’t have much difference and if we display in points it will be like :

1. The cost of DDR3 is lesser than DDR4.
2. DDR3 consumes more power than DDR4.
3. Speed of DDR4 is faster than DDR3.
4. DDR4 has no limit and this makes it more effective than DDR3.
5. DDR3 has lower latency than DDR4.
6. DDR4 has more latency than DDR3.

Let’s see the advantages of both:-

Advantages of DDR3:

• DDR3 transfers data at a higher rate, as much as 6400MBps
• It enables higher bandwidth or peak data rates.
• DDR3 uses less power consumption.
• DDR3 offers battery latency compared with DDR2.

Advantages of DDR4:

• It offers higher module density and also consumes very less power.
• DDR4 is well suited for high-speed games.
• This RAM offers greater DIMM capabilities.
• The data rate transfer is faster when compared with its earlier versions.
• DDR4 can transfer at higher speeds at very low voltage without any cooling requirements.
• The latency of DDR4 is better than any other DDR versions.
• DDR4 refreshes its content only by self-refresh, so it also consumes less power.

Features of DDR3:

•  Data transfer rate: 800 to 1600 MT/s (mega transfers per Second).
• Operating voltage: 1.8 V.
• Lower signaling standard Reduced power x8 prefetch.
• Dynamic ODT for improved write signaling.
• Fly-by architecture.
• Read/Write Levelling.
• Driver calibration.
• Device reset.
• DIMM address mirroring.
• Improved device pinout.

 Features of DDR4:

• Lower signalling standard.
• Reduced power x8.
• Dynamic ODT for improved write signaling.
• Fly-by architecture
• Read/Write Levelling.
• Driver calibration.
• Device Reset.
• DIMM address mirroring.
• Improved device pinout.
• Data transfer rate 2133 to 3200 MT/s.
