In this article, we’ll delve into the details to help you understand whether an i3 is indeed much slower than an i5.
Understanding the Basics: What Do i3 and i5 Mean?
Before we dive into the performance differences, it’s essential to understand what the “i” series means and how Intel differentiates between these processors.
Intel’s “i” series is a branding approach that categorizes their processors based on performance and features. The main difference between i3, i5, and i7 (and even i9) lies in their architecture, clock speed, number of cores, and threads.
- i3 processors are considered entry-level to mid-range and are suitable for general computing tasks, such as web browsing, office work, and streaming.
- i5 processors are mid-range to high-performance and are suitable for more demanding tasks like gaming, video editing, and software development.
- i7 processors are high-performance and are suitable for heavy-duty tasks like 3D modeling, video rendering, and data analytics.
Performance Comparison: i3 vs. i5
Now that we have a basic understanding of the “i” series, let’s compare the performance of i3 and i5 processors.
Clock Speed
One of the most significant differences between i3 and i5 processors is their clock speed, measured in GHz (gigahertz). Clock speed determines how quickly a processor can execute instructions. Generally, a higher clock speed means better performance.
i3 processors usually have a lower clock speed than i5 processors. For example, the 11th Gen Intel Core i3-1115G4 has a base clock speed of 3.0 GHz, while the 11th Gen Intel Core i5-1135G7 has a base clock speed of 2.4 GHz. However, the i5 processor has a higher turbo boost frequency of up to 4.2 GHz, whereas the i3 processor has a turbo boost frequency of up to 3.7 GHz.
Number of Cores and Threads
Another critical difference lies in the number of cores and threads. Cores are the processing units that handle tasks, while threads are the individual tasks that can be executed simultaneously.
i3 processors typically have 2-4 cores and 4-8 threads, while i5 processors usually have 4-6 cores and 8-12 threads. More cores and threads mean better multitasking capabilities and improved performance in tasks that utilize multiple threads.
Cache Memory
Cache memory is a small, fast memory that stores frequently accessed data. A larger cache memory can significantly improve performance.
i5 processors generally have a larger cache memory than i3 processors. The 11th Gen Intel Core i5-1135G7 has a 12MB cache memory, while the 11th Gen Intel Core i3-1115G4 has a 6MB cache memory.
