Why i7 processor is faster than i5

The difference in power consumption between a Core i5 and a Core i7 is fairly small. In our spreadsheet test, laptops pair 20, names and addresses in OpenOffice. The machine with an i5 CPU took 4 minutes and 4 seconds, while the i7 laptop took 3 minutes and 43 seconds. Finally, we put the laptops through some gaming and overall graphics tests. Perhaps because both processors have the same Intel HD graphics, the differences were really small. It has less cache than the i7s and comes with a lower clock speed, though it still comes with four cores and eight threads.

As with desktop chips, Core i7 CPUs tend to be a lot more expensive. Minus a change in cache size — from 8MB on the i5s to 12MB on the i7s — the two ranges are mostly the same. A higher clock speed is better, but you can get by with a lot less especially considering how much more expensive i7s can be in mobile configurations. If you have the extra cash, though, an 11th-gen i7 is a great option. The iG7 consumes the same amount of power as the iG7 while boasting a higher boost clock speed, making it ideal for high-performance thin and light laptops.

To make things even more confusing, Intel also offers 10th-generation Core i5 and Core i7 Comet Lake chips. However, Intel is a lot closer to matching entry-level gaming laptops with Xe, climbing toward 60 frames per second at medium settings in games like Battlefield V and Civilization VI.

The HK rules the roost in the mobile space, packing eight cores and 16 threads into a laptop CPU. It comes with a base clock of 2. Some laptops, like the massively expensive Alienware Aream , actually come with a desktop i9. Not only is the K cheaper, but it also has fewer issues with power and thermals, and it comes with two more cores and four more threads.

If you have workloads that can use the extra power of an i7, consider springing for an i9 especially if you can get a last-gen chip on sale. Laptops are a different beast. Your processor can process more information at once, thanks to more threads and cores. Instead of stressing a single core or thread, the processor spreads out the workload. If you are playing solitaire, then you will not see much between Core i3 and Core i5 processors.

However, If you are editing multiple files in Adobe Photoshop, you can see that Core i5 performs the same task faster compared to old generation processors. Core i7 is a family of high-end performance x86 bit processors developed by Intel. It is designed for high-end desktops and laptops. It is the first processor generation using Nehalem Microarchitecture. However, using Core i7 makes sense only for users who need to use high-resolution software like AAA video games, video editing, or want to render 3D objects.
