What Is Intel Core i5?

Developed and manufactured by Intel, the Core i5 is a computer processor, available as dual-core or quad-core. It can be used in both desktop and laptop computers, and is one of four types of processors in the “i” (Intel Core family) series. The first i5 processor was released in September 2009 and new generations of the i5 continue to be released (2020).

The Core i5 processor is available in multiple speeds, ranging from 1.90 GHz up to 3.80 GHz, and it features 3 MB, 4 MB or 6 MB of cache. It utilizes either the LGA 1150 or LGA 1155 socket on a motherboard. Core i5 processors are most often found as quad-core, having four cores. However, a select few high-end Core i5 processors feature six cores.

The most common type of RAM used with a Core i5 processor is DDR3 1333 or DDR3 1600. However, higher performance RAM can be used as well if it’s supported by the motherboard.

Power usage varies for the Core i5 processors:

  • Slower speeds (1.90 GHz to 2.30 GHz) use 11.5 W of power
  • Medium speeds (2.60 GHz to 3.10 GHz) use 15 W, 25 W, 28 W or 37 W of power
  • Faster speeds (3.20 GHz to 3.80 GHz) use 35 W, 37 W, 45 W, 47 W, 65 W or 84 W of power

Core i5 processors are commonly found in desktop computers for most everyday use and some higher performance needs. Some laptop computers feature Core i5 processors as well, to provide improved performance for heavier usage needs. At the lower speeds, battery usage is pretty conservative and can reach up to five hours or usage on a single charge. However, at higher speeds, battery usage is higher and may result in up to three hours or so of usage per charge.

What Need To Know Core i5

  1. Core i5 is a mid-range processor.
  2. Core i5 processor is dual-core or quad-core processor architecture. A core is usually the basic computation unit of the CPU.
  3. A total of four threads can run on Core i5 at the same time. It has four threads.
  4. Core i5 does not support hyper-threading. Hyper-threading enables a single core to serve multiple threads.
  5. Core i5 has allotted 3 to 8MB of the cache. A cache is a smaller, faster memory which stores copies of the data from frequently used main memory locations.
  6. The clock speed frequency of Core i5 1.2-3.8 GHz.
  7. Core i5 has maximum memory frequency, DDR3-1600.   
  8. Core i5 processors use the DMI bus type.
  9. The process of Core i5 is available in 32nm silicon.
  10. Core i5 supports high definition quality.
  11. Core i5 has the feature of turbo-boosting. Turbo-boosting feature enables the processor to increase the number of clock cycles dynamically when the need arises.
  12. The cost of Core i5 system is relatively less than the Core i7 system.

What Is Core i7?

Intel Core i7 is a line of Intel CPUs which span eight generations of Intel chipsets. They feature either four or six cores, with stock frequencies between 2.6 and 3.7 GHz. The first i7 processors were released in November 2008 and new generations of the i7 continue to be released (2020).

Variations of the i7 processor are manufactured for a variety of personal computing devices. Some high-performance i7 processors for desktop computers, such as the i7-8700K, are unlocked for overclocking. High-efficiency i7 processors (which conserve energy as much as possible, at the expense of some performance) are manufactured for desktop computers, laptops, and mobile devices.

An i7 is an ultra fast CPU for professional users that require excellent performance for multiple processes at once or advanced processes that make good use of multiple cores/threads (video editors, 3D artists, and professional twich users). Thus, the i7 processor is marketed primarily to gaming enthusiasts, and digital artists such as filmmakers and animators.

What Need To Know Core i7

  1. Core i7 is a high-end processor.
  2. Core i7 processor is dual core, quad-core and hex-core processor architectures.
  3. A total of eight threads can run on Core i7 at the same time. In other words, it has 8 threads.
  4. Core i7 supports hyper-threading for multitasking and high-end video games.
  5. Core i7 has allocated around 4 to 8MB of cache memory. Both RAM and Cache serve as holding areas for frequently used data. Without them, the CPU would have to keep on reading from the hard disk, which would take a lot more time.
  6. The clock speed frequency of Core i5 2.6-3.7 GHz. 
  7. Core i7 has maximum memory frequency DDR3-1333.
  8. Core i7 processors use the QPI bus type.
  9. The process of Core i7 is available from 14nm to 45nm silicon, in various generations implemented by different codenames.
  10. Core i7 supports HD 650 to HD 3000 quality offered by different companies at varied generations.
  11. Core i7 has the feature of turbo-boosting, but core i7 achieves maximum clock speeds.
  12. The cost of Core i7 system is relatively more than the Core i5 system.
