DDR5 RAM: The PC’s Next-Gen Memory

If you are interested in DDR5 random access memory (DDR5 SDRAM) and want to learn more about it, you should not ignore this article. We will introduce you to the DDR5 RAM and the information related to it.

These days, you can find different types of RAM in the market, such as DDR3 RAM and DDR4 RAM. But few people understand and know DDR5 RAM – a new type of ram is about to enter the market.

DDR5 RAM released date

In a recent blog post, Corsair confirmed that DDR5 memory is coming soon. It may coincide with the release of Intel’s Alder Lake-S CPUs at the end of the year. 

AMD’s Zen 3+ processors are not able to support DDR5 RAM. AMD users have to wait until Zen 4 to land on shelves in 2022. 

DDR5 SDRAM (DDR5 RAM) stands for Double Data Rate 5 Synchronous Dynamic Random-Access Memory. It is the successor of the DDR4 RAM series, which is expected to double the bandwidth and reduce the power consumption.

DDR5 RAM performance

The DDR5 is designed to boost the performance twice of first-generation DDR4 modules.

The DDR5 bus 3200 RAM will increase the bandwidth to 1.36 times over the DDR4 bus 3200. However, the DRAM 5 chip is expected to reach a bandwidth of 4800MT/s or 1.87 times higher than the DDR4 3200 RAM. The official limitation of DDR5 RAM is 6500MT/s, but some models will be able to be even higher through overclocking.

SK Hynix has been working on DDR5 modules to provide 16GB (2GB) capacity per chip. The usage voltage dropped from 1.2V to 1.1V (compared to the DDR4 modules), allowing it to reduce power consumption. 

Moreover, DDR5 RAM includes two independent 40-bit channels on each module, which improves data processing efficiency and performance.

Should I buy DDR5 RAM?

The cost to upgrade to DDR5 is quite expensive at present since it is a new product hitting the market. However, it will decrease over time, and of the components that make up a PC, RAM is always cheaper.

On the other hand, once DDR5 becomes more and more popular, users will be able to save some money even if they opt for 8GB or 16GB storage. In addition, the bus speed of RAM has not been of interest to many users for a long time because they do not provide noticeable performance. Only when you play heavy gaming titles can you clearly feel its difference.

Until then, DDR4 is still an excellent kit for every PC build.
