A processor is the brain of a computer which is a logic circuit that responds and processes the fundamental instructions that drive a computer. Fetching, decoding, executing and write back are the four key functions of a processor. Intel keeps on introducing advanced processors including its sixth generation Skylake Micro architecture and eighth generation Kaby Lake. It offers processors at different prices with a wide range of capabilities. Core i5 and i7 are popular and in trending. Here you are having a study of the difference between i7 processor vs. i5 processor. It might help you to choose the best for you.
Why shall i5 be considered?
Generally, Intel Core i5 processors are less expensive than Core i7 processors. An i5 processor is Intel’s mainstream processor line and lies between with more economical Core i3 chips and high performers’ i7 and i9 models. Nevertheless, know that each processor family will have different micro architectures and internal components can assemble an i5 model run faster than a particular i7 model. So, check with the specifications carefully.
Intel Core i5 processors are extremely capable for Laptop and Desktop. If you are using a computer for home application, internet browsing and some more light work, then Intel Core i5 processor is a wise choice.
Why shall i7 be considered?
Core i7 processor is faster and capable than Core i5. The latest i7 chips bring up to six cores and 12 threads which makes the i7 processor suit better for multitasking functions.
Core i7 processors are ideal for high-end gaming, Adobe’s Creative Suite, scientific work and multimedia consumption. If you find your laptop is slow while running the above-cited applications, then going for a Core i7 processor is a good option.
The differences and price
There is no huge difference between the U-series Core i5 and Core i7. There are no large architectural differences between i5 and i7. The i7’s base clock speed is faster than the i5. So you can smack to a higher clock speed on the i7 with the Turbo Boost than the i5. It put the i5 in the mainstream tier and the i7 in the fanatic tier. The price of i7 is significantly higher than i5.
In a research, a Video Transcoding tool was used to simulate heavy processing. For the particular research, the tool was applied to both the laptops to covert a 4K .mov file to a 1080p .mp4 file. Since it was a taxing process, both the laptops took its own time to convert it. Within 31 minutes and 27 seconds, Core i5 laptop completed the conversion whereas Core i7 completed the process within 30 minutes and 17 seconds. The Core i7 was faster by 1 minute and 10 seconds.
If you analyze power consumption between a Core i5 and Core i7, it is absolutely small. In a Laptop Mag Battery Test, the Inspiron with Core i5 processor lasted for 5 hours and 48 minutes. It was involved with continuous web surfing over Wi-Fi while a Core i7 lasted for 5 hours and 22 minutes. You will not get any major changes unless the i7 is pushed to its limits and run it at a higher clock speed.
If you are a serious game buff or video editor, then larger laptops with quad-core Core i5 or Core i7 that are the key parts of the HK/HQ series. In such series, the i7 chips can run eight threads whereas in the Core i5 models only four threads can run which might provide a larger delta in performance. Web browsing, streaming some videos and working on Word documents can be performed fairly with i5 processor. So, choose either the processors according to your need.
