1、What Is DDR?
DDR, Double Data Rate, is a dynamic random access memory (DRAM) technology, which represents double data rate synchronous dynamic random access memory and improves the data transfer rate compared to traditional SDRAM (Single Data Rate). If the DDR installed on the device is too slow or has insufficient capacity, the required programs will not be able to run on the device.
In 2000, DDR memory was released. In the past ten years, most PCs have been running DDR4 memory, and now DDR5 is gradually becoming the new standard of this era.
It can be said that each iteration of DDR has improved performance compared to its predecessor, from the 2.7-3.2GB/s transfer rate of DDR1, to the 21GB/s of DDR4, to the 6.4Gbps of DDR5, significantly increasing the data processing speed. And provides the possibility for more complex computing tasks.
2、What Is DDR5?
DDR5 is the fifth iteration of DDR, with twice the bandwidth and capacity of DDR4. Applications can do more things at the same time and generally have more efficient computing. These enhancements make DDR5 an ideal choice for artificial intelligence (AI) and machine learning data-intensive workloads. Now that DDR5 has been on the market for three years, it is now cheaper and more widely used.
At the same time, DDR4 is gradually being phased out of the market. It is reported that Intel's next-generation Core series processors will no longer support DDR4, while AMD will abandon support for DDR4 when it releases its Ryzen 7000 series processors at the end of 2022.
But DDR4 is still a very fast memory module specification, and if you pursue cost-effectiveness, it is worth choosing to continue using DDR4.
3、The Difference Between DDR4 vs DDR5
(1) Memory Bandwidth
One of the main differences between DDR4 and DDR5 RAM is speed. The JEDEC specification for DDR4 runs at an effective speed of up to 3200MHz, higher than the initial 2133MHz at launch, while the default speed of DDR5 RAM is 4800MHz, with an effective operating speed of up to 6400Mhz.
Compared to DDR4, with DDR5, data transfer rates can be increased by 50%, and industrial pc manufacturers are continuing to discuss how to further increase bandwidth. In the future, DDR5 may run at 8000MHz or higher frame rates, more than doubling the data transfer rate of DDR4.
(2) Voltage
DDR4 operates at 1.2V, while each DDR5 module has its own PMIC (power management integrated circuit), which requires less power, and Vdd drops from 1.2v to 1.1v.
While a 0.1V power saving may not sound like a lot, it can actually reduce power usage by 20%, especially in industrial environments that require continuous operation 24/7, this energy efficiency can save a lot of money.
Also, using less power means less heat is generated, which helps improve the stability of the device, especially for embedded solutions.
(3) Capacity
DDR4 can support DIMMs with a capacity of up to 64GB. DDR5 can support 8 times the capacity of DDR4 - up to 512GB per DIMM, allowing a single user to handle larger, more memory-intensive projects.
However, most processors cannot support this yet. The best ones are high-end motherboards such as the Gigabyte Aorus Z790 Extreme X, which support up to 192GB of total memory and 48GB of independent memory modules.
As technology develops, we believe that it may only be a matter of time before CPUs can fully utilize DDR5 capabilities.
(4) Latency
RAM acts like temporary storage for a computer's CPU, allowing for quick access to regularly executed tasks, similar to when we open multiple applications on our phones. When we use one, the other applications remain running in the background, making it easy to quickly switch between them. The lower the latency, the faster the CPU accesses instructions temporarily stored in RAM to execute tasks.
With the continuous upgrade of DDR, each generation of memory has increased CL compared to the previous generation, and so has DDR5, but the clock cycle time has become faster. Combined with DDR5's huge advantage in ultra-large transmission speed, it almost eliminates the total latency gap.
(5) Performance
For heavy scene rendering or video file encoding, DDR5 has significantly higher performance. After testing, on a system equipped with DDR5, the lengthy test scene in Blender was rendered one to two minutes faster; on a system equipped with DDR5, the same video file encoded with Handbrake was also about a minute faster.
DDR5 is faster than DDR4 in the most intensive applications, but for everyday tasks, the difference in real life is small and DDR4 is sufficient to meet the needs. You can choose based on the specific application scenario.
4、Is DDR5 really that much better than DDR4?
Based on the above introduction, it is not difficult to see that DDR5 is indeed better in terms of functions and advantages. First, DDR5 is faster and can transmit data at a higher frequency, making the system more efficient when processing large amounts of data. Second, DDR5 has a higher bandwidth and can transmit more data at the same time, which is very beneficial for tasks that require large amounts of data processing, such as games and video editing. In addition, DDR5 is more energy-efficient and efficient than DDR4, and can reduce energy consumption while providing higher performance, which helps improve the overall efficiency of the system and battery life.
However, the price of DDR5 is relatively high. Overall, DDR5 is a better choice for users who pursue high performance and high efficiency, but for general users, DDR4 is still a more cost-effective option.
5. Is it worth upgrading to DDR5?
Now, DDR5 is faster than DDR4, and the latest motherboards and processors are gradually phasing out DDR4 memory. If you want to pursue the latest technology, you can upgrade to DDR5, but you also need to upgrade the motherboard and processor and ensure that there is enough power supply.
DDR4 is not outdated on the market, and there are more compatible devices than DDR5. DDR4's performance is still excellent for most tasks. If there is a problem with storage capacity, you can upgrade DDR4 memory to 32GB or 64GB modules. Increasing the bandwidth of memory will make a greater difference than switching to DDR5, and it is more cost-effective.
