Dual-core refers to a CPU that includes two complete execution cores per physical processor. It has combined two processors and their caches and cache controllers onto a single integrated circuit (silicon chip).
what is core i5?
Developed and manufactured by Intel, the Core i5is a computer processor, available as dual-core or quad-core. It can be used in both desktop and laptop computers, and is one of three types of processors in the "i" series (also called the Intel Core family of processors).
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 the motherboard supports it).
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 is core i7?
The Intel i7 processor is Intel's top end processor, with several variations available. The i7 processor is available for both desktop computers and laptop computers, available in many different gigahertz speeds and several socket types. There have also been several generations of the i7 processor released as well. Whatever the needs of the user are, an i7 processor is available to meet those needs.
The i7 processor is a popular choice in the consumer and business market for a wide range of uses and are available in speeds as low as 1.07 GHz and as high as 3.6 GHz. The first i7 processor was released in November 2008, and since then, there have been over 60 versions released for desktop and laptop computers. The i7 ranges from 4-10 cores based on the model. Benchmark tests done on the i7 processor produce some of the best marks and ratings in the industry.
what is core i3?
Developed and manufactured by Intel, the Core i3is a dual-core computer processor, available for use in both desktop and laptop computers. It is one of three types of processors in the "i" series (also called the Intel Core family of processors).
The Core i3 processor is available in multiple speeds, ranging from 1.30 GHz up to 3.50 GHz, and features either 3 MB or 4 MB of cache. It utilizes either the LGA 1150 or LGA 1155 socket on a motherboard. Core i3 processors are most often found as dual core, having two cores. However, a select few high-end Core i3 processors are quad core, featuring four cores.
The most common type of RAM used with a Core i3 processor is DDR3 1333 or DDR3 1600.
Power usage varies for the Core i3 processors:
- Slower speeds (1.30 GHz to 1.80 GHz) use 11.5 W, 15 W or 25 W of power
- Medium speeds (2.00 GHz to 2.50 GHz) use 28 W, 35 W or 37 W of power
- Faster speeds (2.90 GHz to 3.50 GHz) use 35 W, 37 W or 54 W of power
Core i3 processors are often used in laptop computers, due to their lower heat generation and conservative battery usage. Some laptops can be used for up to five or six hours on a single battery charge when running a Core i3 processor.
