Differences between i3 and i5
Contents
Intel Core i3 vs. Core i5[edit]
Intel's Core i3 and Core i5 are two lines of central processing units (CPUs) that represent different tiers in the company's processor offerings.[1][2] Generally, Core i5 processors include more performance-enhancing features and offer more processing power than Core i3 models from the same generation.[3] The specific features, such as the number of cores, clock speed, and cache size, vary between generations and individual models.[1] The primary distinctions often relate to core count, the inclusion of Turbo Boost technology, and cache size.[4]
Comparison Table[edit]
| Feature | Core i3 | Core i5 |
|---|---|---|
| Target Use | Entry-level computing, web browsing, office applications, and streaming media.[5][2] | Mainstream computing, multitasking, media creation, and gaming.[3][5] |
| Core Count | Typically feature fewer cores than i5 processors of the same generation. Modern i3 processors commonly have 4 cores.[4] | Typically feature more cores than i3 processors. Modern i5 processors commonly have 6 or more cores. |
| Hyper-Threading | Often included, allowing each physical core to function as two logical cores, or threads, to improve multitasking. | Often included, which effectively doubles the thread count relative to the core count. |
| Turbo Boost | Generally not available. Processors operate at their base clock frequency. | Generally included. This technology allows the processor to automatically increase its clock speed above the base frequency to handle demanding tasks. |
| Cache Size | Smaller L3 cache size, typically ranging from 6MB to 12MB in recent generations. | Larger L3 cache size, often ranging from 12MB to 24MB or more in recent generations, which helps with multitasking and repetitive tasks.[3] |
| Integrated Graphics | Includes integrated Intel UHD Graphics, sufficient for everyday tasks and light gaming. | Includes more advanced integrated graphics, such as higher-tier Intel UHD or Iris Xe Graphics, providing better performance in graphically demanding applications. |
| Price | Positioned as a budget-friendly and entry-level option.[4][1] | Positioned in the mid-range, costing more than i3 processors but offering greater performance.[4][3] |
Core and Thread Count[edit]
A key difference between the i3 and i5 series is the number of physical processor cores. Core i5 processors generally have a higher core count than their i3 counterparts from the same product generation.[1] For example, 10th-generation desktop i3 processors typically had 4 cores, while i5 processors had 6. More cores allow a processor to handle more tasks simultaneously, which can improve performance in multi-threaded applications like video editing and modern games.[3]
Both processor lines often feature Intel's Hyper-Threading technology. This allows a single physical core to be treated by the operating system as two logical cores, known as threads. Hyper-threading can increase efficiency by allowing the core to work on a second task while the first is temporarily stalled, improving overall throughput. For instance, a 4-core i3 processor with Hyper-Threading can process 8 threads. Similarly, a 6-core i5 with the feature can handle 12 threads.
Clock Speed and Turbo Boost[edit]
While base clock speeds can be similar between some i3 and i5 models, most Core i5 processors include Intel Turbo Boost Technology, a feature largely absent from the Core i3 line. Turbo Boost dynamically increases the processor's operating frequency when the workload demands higher performance, as long as the CPU is operating within safe temperature and power limits. This allows an i5 to achieve higher clock speeds for short bursts, improving responsiveness in demanding applications. Core i3 processors, without this feature, are limited to their specified base frequency.
Cache[edit]
Core i5 processors are equipped with a larger amount of on-chip cache memory (L3 cache) than Core i3 processors.[4] The cache is a small amount of very fast memory that stores frequently used data, allowing the CPU to access it more quickly than retrieving it from the main system RAM.[3] A larger cache can improve performance in tasks that involve repetitive data access, such as gaming and multitasking, as more information can be stored for immediate use.[3][5] For example, 10th-generation desktop i3 processors were equipped with 6MB of L3 cache, whereas their i5 counterparts had 12MB.
