COMPARISON OF CPU

List of CPU among all laptop of each team member

· Intel Celeron Quad Core N2940 (up to 2.25GHz, 1MB L3 Cache) 

· Intel Quad Core N2940 (1.83GHz, 1MB L3 Cache)

· Intel Core i3-5005U 2 GHz, Dual-Core

· Intel Core i5 3317U 1.70GHz, Dual-Core

· Intel Core i5 5200U / 2.2 GHz Dual-Core

Before we compare the different type of processor, we should know what the core means. Every laptop is built with only one processor chip. That chip can have one, two, four, six, or eight cores. Each “core” is the part of the chip that does the processing work.

Speed

Quad Core > Dual Core

Although more cores will faster the processor, they are faster only if a program can split its tasks between the cores as not all programs are made to split tasks between cores.

Quad Core 2.25GHz > Quad Core 1.83GHz>Dual Core 2.2GHz> Dual Core 2GHz> Dual Core 1.70GHz

The clock speed of each core also is a crucial factor in speed, as is the architecture. A newer dual core CPU with a higher clock speed will often outperform an older quad core CPU with a lower clock speed. 

Power Consumption

Core I5 3317U > Core I5 5200U & Core I3 5005U > Celeron N2940

More cores also lead to higher power consumption by the processor. When the processor is switched on, it supplies power to not only one at a time but all the cores. Therefore, a quad core processor will draw more power from your laptop. However, Celeron N2940 Quad Core is less power consumption than the others although it has double number of cores than others. This is because it is built to minimize the power consumption and more advance than other processors. Core I5 5200U has been improved to consume less power than Core I5 3317U. This is one of the diffrence between fifth generation processor and third generation processor.

For Gaming, Video & Audio Editing

Quad Core > Dual Core

PC hardcore games mostly dependent on the graphics card to look good and more core processor also important too. Those professional who works with video or audio programs, more cores will be beneficial. This is due to the popular audio and video editing tools that take advantage of multi-threaded processing.

Based on the chart above, Celeron N2940 has the most number of cores among all CPU compared to Core I3 and Core I5 which are only 2 cores. It also has the highest operating frequency which is 2.25GHz which is higher 0.25GHz than Core I3, 0.55GHz than Core I5 3317U and 0.05GHz than Core I5 5200U. Moreover, the lowest power consumption is Celeron N2940 which is just need 7.5W to operate. Second lowest are Core I3 and Core I5 5200U which need 15W. Core I5 3317U is the highest thermal design power which is 17W. However, Celeron N2940 has less On-chip L2 + L3 cache memory(2.048MB) than Core I3(3.584MB) and both Core I5(3.584MB).

Therefore, it can be concluded that Celeron N2940 processor is the best CPU among the processors that listed above. This is because it is the fastest for programs that are made to split tasks between cores and less power consumption.
