The single-letter suffix on each model of processor denotes whether it can be overclocked K , or is low-power S or ultra-low power T. An opinion about the relative performance differences between each model of processor can therefore be quickly formed. In essence, Core i5 processors are designed to be more affordable, lower performing versions of the Core i7 parts. There will certainly be some overlap in performance between the highest-end i5 processors and the cheapest i7 versions, but in essence the Core i5 range has a smaller cache 6MB rather than 8MB , a fewer maximum number of threads 4 not 8 and the omission of Hyper-Threading HT Technology.
AMD Ryzen 7 G 3. The more cores a processor has, the more tasks known as threads can be served at the same time. Hypothetically, a dual-core processor can serve two threads at once while a quad-core processor can serve four and an octa-core processor can serve eight. In theory, this means that a PC powered by quad-core processor is able to operate and complete tasks with greater efficiency than one with a dual-core processor.
In addition to the number of Cores, the other metric that matters here is the clock speed of a given CPU. Measured in Gigahertz, clock speed measures the default or factory-set speed with which the processor normally operates. Many processors can be modified to go faster than that speed through overclocking but the normal clock speed is a good tool for measuring their relative performance power.
More like core count, higher is better here. A processor with a faster speed can operate more more efficiently compared to one with a slower speed. However, due to thermal restrictions, processors with more cores tend to operate at a lower clock speeds.
This is why having a PC with the most cores might not always be the thing you want. At this point, it's important to take the opportunity to start talking about how a number of factors can affect the overall processing power of a CPU. The number of cores involved shouldn't be your only consideration when you're trying to determine whether you should consider buying an Intel Core i3, Core i5, or Core i7 processor but it is useful as a place to start. You can't understand or appreciate the significance of stuff like Turbo Boost and Hyper-Threading without having some foundational knowledge of clock speed and core count.

It would be faster running a single-threaded application, which can only use one core, than a Core i, which only has a clock speed of 3.
However, running a multi-threaded application, the Core i5 would most likely be quicker, as its four real cores are better than the Core i3's two cores and Hyper-Threading. Turbo Boost is Intel's technology for automatically overclocking a processor, boosting its clock speed higher than the default setting.
The CPU monitors its temperature and, when it's running cool enough, will apply the overclock. Core i5 and i7 CPUs have this technology, Core i3 models do not. This means that you can use BIOS settings to up the clock speed of the chip, overclocking it yourself. We've seen big improvements in performance this way - we pushed the Intel Core iK chip to 4. All Intel processors have graphics chips in them. Pre-Haswell, the GPUs weren't particularly good for games, although they were fine for watching video.
With Haswell, came the Intel HD Graphics line, which is fine for a bit of light gaming; some cheaper models we'll show you how to check later have HD Graphics chips, which are fine for some older less-demanding games. Some of the more expensive chips have Intel Iris Pro chips in them. They're slightly faster in games, but can cope with 4K video, making them suitable for high-end video editing.
In all cases, if you're serious about playing games, Intel chips don't cut it and won't give you high-resolution, high-detail gaming. We recommend buying a dedicated graphics card instead. As always, there are some exceptions to the rules.
For example, the Core iT has two cores and Hyper-Threading. Fortunately, these models aren't generally available and we recommend avoiding any of these strange models unless you have a specific reason for wanting one.
