What should i get i5 or i7

Core i5 Processor is dual-core or quad-core whereas Core i7 processor is dual-core, quad-core and hex-core processor architectures.

Hyper-Threading is not possible in Core i5 processor but it is possible in Core i7 processor. The clock speed of Core i5 is 1. The battery of Core i5 processor last for 14 hours and 45 but and the battery of Core i7 processor last for 10 hours and 49 minutes. Report a Bug. Previous Prev. Next Continue.

This means that a PC with a higher core-count is going to be better for tasks where multithreading is important, such as web servers, web browsers and some video games. The reason for this is that i3 processors are designed to hit a lower price-point more than they are push boundaries for performance. They tend to be found inside PCs that target a more budget-conscious market-segment where the need for a device to be affordable eclipses the demand for higher performance.

Part of this comes down to faster average clock speeds. Part of this comes down to additional cores. More cores means these CPUs can handle more threads at once and faster clock speeds mean they can complete tasks more efficiently.

At this point, you may be wondering just how important clock speeds are. The answer: pretty important. The first is that, in general, a higher clock speed is better. However, due to the thermal issues involved, processors with more cores tend to operate at a lower clock speed. Often-times, choosing a CPU involves choosing between a CPU capable of delivering faster clock-speeds or choosing one with more cores. Although a faster core might be more efficient than a slower one, it might not necessarily be better for the tasks you want to use your computer to be better at.

Many applications only run single-threads while others are designed to utilize multiple. For cases where the latter applies, such as video rendering and gaming, having more cores is going to offer up an enormous improvement over having faster ones. Rather than run out and dropping the cash on the CPU with the fastest clock speed you can find, it might be worth thinking about what the clock speed you actually need looks like.

To that end, it's worth looking up the recommend system specifications for the game or software you'll be running on your new PC. It should be the most readily available chip, and it supports overclocking. The K comes with a little more juice than the K. It has eight cores and 16 threads, a base clock of 3. Out of all the current desktop offerings, we recommend the iK most. It represents an excellent value, with enough power for gaming and light productivity tasks.

Intel currently offers its Tiger Lake processors for thin and light laptops. These chips pack in as much power as possible while keeping power and thermal demands low. The lineup is fairly straightforward. There are two i5 processors, the iG7 and G7, each of which comes with four cores and eight threads.

Similarly, there are three i7 processors — the iG7, iG7, and iG7 — and they all match the same core and thread count as the i5s. The difference: Each of the processors has a slightly different boost clock speed, starting at 4. Intel offers some variations of each of these processors for system makers and certain use cases.

The company expanded its Tiger Lake lineup in early with the iG7, iG7, and iG7. Like the other chips, the only thing that separates these processors is clock speed. Outside of thin-and-light laptops, Intel has its Tiger Lake H35 chips. The best of the bunch is the iH, which features four cores, eight threads, and a boost clock of 5GHz. Intel offers a single high-performance i5 in this range: The iH.

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.
