What is Dell i5?

Dell i5 processor can perform with integrated memory. This feature helps in enhancing the productivity of the applications.

The memory speed associated with it boosts up to 1333 MHz. The processor has a comparatively high rate of rapid performance.

The maximum speed up to which it can work is approximately 3.6 GHz of CPU rate. The speed of working associated with computational systems gets enhanced with the help of the Turbo technology embedded in the Dell i5 processor.

The reliable working shown by the i5 processor is due to the 64-bit architecture. The CPU score for core i5 is 13,179. It was launched between January 2010 and April 2018.

The Time taken for video transcoding in the CPU of Dell i5 is 18 minutes and 28 seconds. Mid-range graphics are supported in this processor.

Dell i5 also involves some disadvantages for the users as it does not support the users to use technology for high data visualization. Thus, the users are not able to access high video graphics or images of high picture quality.

It has high power consumption and has high demands for advanced or newer motherboards. Dell i5 processor is vulnerable to voltages of high-end.

It is ideal for office work or gaming regularly.

What is Dell i7?

The i7 processor can enable 64-bit execution. It has the feature of 2 GH of front-side bus speed.

It enables a high rate of speed working along with the characteristic to enable multitasking during its usage. It supports the technology for hyper-threading.

The processor also can encourage the main memory of DDR3. The CPU score of core i7 is 13,335.

It was launched between September 2009 and April 2018. It can offer high processing speed and is associated with a quality cooling system.

Software needing high computations can be tacked by the four cores very adequately.

Dell i7 offers technology for high data visualization that enables users to access high-quality video graphics and high-quality images. The processor is appropriate for digital artists and gaming enthusiasts.

However, the i7 is comparatively more expensive than the Dell i5 and has high power consumption than other processors.

As these processors are compatible with DDR3 memory, it demands a new or advanced motherboard while working with DDR2.

Multithreading is not associated with software, and the users do not attain performance as expected. The I7 processor is chosen when the user requires supercomputing power in the server.
