At the most basic level, these numbers reflect where each class of Intel Core CPU sit relative to one another and are intended to give consumers an idea of the kind of performance they should expect from each. Essentially, the idea that Intel are looking to convey with this CPU classification system is that PC builders should expect:. Some are intended for us inside laptops, others are intended for use with desktop PCs.
Wattage is the big differentiator here, since CPUs inside mobile devices generally have to make do with less power draw,. However, to avoid confusion, let's start by exclusively talking about the desktop variants. 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. The last letter tells you what kind of processor you're dealing with — K means it can be overclocked easily, and Intel has a full guide to this.
There is another important consideration: graphics. Again, the i7 models typically outperform the i5 models, but if you're installing a separate graphics card to take the brunt of generating the visuals, then that will largely negate the differences. You can see that choosing between i5 and i7 isn't just a straight up choice between processors and prices.
If you're pushed into a corner at a very geeky dinner party and asked to explain the differences between Intel i5 and Intel i7, you can get away with saying the i7 processors are more powerful and more expensive. When it comes to actually buying a computer though, be wary of paying the extra cash for an i7 upgrade, because it's not always worth it — look up the performance of the processor model numbers you're considering on the web, in the tasks you're going to be doing, to help make a decision.

Writing by David Nield. Originally published on 27 July Recommended for you. What is Windows 11 SE? There are three main i5s right now: The i, , and Each of these processers comes in multiple variations. The K sports six cores and 12 threads, with a TDP of watts. It has a base clock of 3.
With those specs, the K is a monster CPU for gaming and capable enough to handle applications like Photoshop and Premiere. Rocket Lake only has a single i7 chip: The i Like the range of i5s, this processor comes in several variations with different features. 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.
