Introduction: The Role of RAM in Web Hosting

When selecting a web hosting service plan—like shared hosting, cloud VPS, or dedicated server hosting—one hosting server resource that often doesn’t get the same attention as CPU and storage is memory, or RAM. However, RAM is important to the overall efficiency of your website or application.

RAM is critical when it comes to processing incoming requests, storing cached data, running server-side scripts, and supporting database queries. In modern hosting environments, where the demands of content-heavy websites, eCommerce solutions, and real-time applications continue to rise, memory speed and efficiency can determine performance.

The jump from DDR4 to DDR5 memory is arguably one of the biggest generational upgrades in server hardware we have seen in recent memory. This blog aims to illustrate the differences between DDR4 vs DDR5 in a real-world capacity, while also identifying whether moving to DDR5 will benefit your hosting requirements.
