DDR4 vs. DDR5 RAM: Which One is Right for You?

Choosing Ram depends on the requirement, DDR4 being cheaper but lacking a bit of performance on the other its vice versa DDR5 is expensive but performance is better but maybe you don’t require such performance hence look my article and chose what’s good for you.

By doing some research I tired to help you comparing different things like bandwidth, power consumption, performance etc.

DDR4 vs. DDR5 RAM Gaming FPS Comparison

GameDDR4 (3200 MHz)DDR5 (4800 MHz)
Cyberpunk 207760 FPS65 FPS
Call of Duty: Warzone120 FPS130 FPS
Fortnite144 FPS150 FPS
Apex Legends100 FPS110 FPS
Cyberpunk 207760 FPS55 FPS


DDR5 RAM has a higher bandwidth than DDR4 RAM. This means it can transfer data faster. DDR5 RAM has a theoretical maximum bandwidth of 6400 MT/s, while DDR4 RAM has a theoretical maximum bandwidth of 3200 MT/s.

Power consumption

DDR5 memory consumes less energy than DDR4 memory. This is because DDR5 RAM operates at a lower voltage. DDR5 RAM requires about 1.1V, whereas DDR4 RAM requires about 1.2V.


In some applications, DDR5 RAM has the potential to outperform DDR4 RAM. The specific application will determine the extent of the performance improvement. In some cases, DDR5 RAM can outperform DDR4 RAM by up to 10%.


DDR5 RAM is more expensive than DDR4 RAM. Because it is newer technology, this is the case. Although the price difference between DDR4 and DDR5 RAM is shrinking, DDR5 RAM remains more expensive.


DDR5 RAM is less widely available than DDR4 RAM. This is because DDR5 is the newer technology and is still being rolled out. However, the availability of DDR5 RAM is improving, and it is becoming more common to find DDR5 RAM for sale.


DDR5 RAM outperforms DDR4 RAM in several ways, including increased bandwidth, lower power consumption, and improved performance. However, it is more expensive and less widely available.

Your personal needs and budget will determine whether you use DDR4 or DDR5 RAM. If you’re building a new PC and want the best performance possible, DDR5 RAM is the way to go. There is no need to upgrade to DDR5 if you are on a tight budget or your current PC uses DDR4 RAM. DDR4 RAM is still a great option that will be supported for many years.

The other factors which may be important for you:

  • The applications you use. If you use applications that require a lot of data transfer, such as video editing or gaming, DDR5 RAM may be a good choice.
  • Your current financial situation. DDR5 RAM is more expensive than DDR4 RAM, so if money is an issue, DDR4 RAM may be a better choice.
  • DDR5 RAM is now available. DDR5 RAM is less common than DDR4 RAM, so if you need RAM quickly, DDR4 RAM may be a better option.
