Recently, some computer enthusiasts have asked Xiaobian such a question: Is the new installed machine DDR4 or DDR3 memory good now? For this problem, many netizens will say that it is definitely a new generation of DDR4 memory, because it consumes less power and performs better. However, Xiao Bian believes that there are some misunderstandings here, because DDR4 and DDR3 memory are not compatible, and there are still price-performance differences between different hardware platforms. Therefore, this problem can be said that it is not the only answer.
Let me talk about the difference between DDR4 and DDR3 memory:
1. DDR4 is faster than DDR3 memory
The starting frequency of DDR3 memory is 800, the highest frequency is 2133, and the starting frequency of DDR4 memory reaches 2133, and the highest frequency reaches 3000. At present, the mainstream DDR3 memory is 1600 frequency, while the mainstream DDR4 memory frequency is 2133. Under the same capacity, DDR4 memory performance will be even better, with an increase of more than 20%.
2. DDR4 consumes less power than DDR3
The standard operating voltage of DDR3 memory is 1.5V, while DDR4 is reduced to 1.2V. The low-power DDR4 designed for mobile devices is reduced to 1.1V, and the lower operating voltage means lower power consumption.
In addition, the current price of DDR4 memory and DDR3 is basically the same, the same as 8GB of memory, the price is basically around 220-280 yuan, the price is basically the same.
8GB DDR3 1600 memory price
8GB DDR4 2133 memory price
Based on this, DDR4 memory has improved significantly compared to DDR3. It is no wonder that many netizens are calling for DDR4 memory in new installations.
DDR3 and DDR4 memory are not compatible
However, there is a problem to be noted here, that is, DDR4 memory and DDR3 memory are not compatible, and the memory slots of the two are different. This leads to not all motherboards supporting DDR4 memory, especially the majority of motherboards below 100 series. Does not support DDR4.
Therefore, when installing the new machine, we need to consider whether the motherboard supports DDR4 memory. In addition, not all CPUs support DDR4 memory. Only the six generations of processors introduced by Intel at the end of last year only support DDR4 memory. AMD currently does not support DDR4 memory for all processors, and it will not be until the end of the year to launch Zen processors. Join DDR4 memory support.
In addition, although DDR4 memory is much better than DDR3, if the selected CPU and motherboard do not support DDR4 memory, we can't use DDR4 memory, otherwise it will be incompatible and cannot be installed normally.
Finally, we need to consider a price/performance problem. Although the price of DDR4 and DDR3 memory is equivalent, the CPU and motherboard that need to be supported are different. For example, the new generation of 100 series motherboards and six generations of CPUs supporting DDR4 memory are more expensive than Intel's previous generation CPU. And 8 series motherboards are more expensive, if it is based on cost-effective or cost-saving considerations, the previous generation of platform computers with DDR3 memory may be more affordable.
Editor's note:
Regarding the current new installation is to choose DDR4 or DDR3 memory, in terms of memory itself, DDR4 memory with better price and better control of power consumption is a better choice. However, sometimes DDR4 memory is not what you want to use. It is not compatible with DDR3 memory slots. It can only be experienced on some new platforms. The installed budget is relatively expensive. If you stick to the previous generation platform, you can only choose it. DDR3, but the price/performance ratio will be slightly better, so it is mainly based on these two aspects.
