In terms of performance, Hyper-Threading speeds up multi-tasking and multi-threaded applications. It's not as fast or as efficient as extra 'real' cores, but it's an improvement over a single Core. Core i3 and i7 processors have this technology, Core i5 processors do not. The faster the clock speed in MHz, the faster each core can run. This can create some variances in performance. For example, a Core i Haswell processor runs at 3.
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.
The physical cores largely determine the speed of a processor. But with how modern CPUs work , you can get a boost in speed with virtual cores, activated through hyper-threading. In layman's terms, hyper-threading allows a single physical core to act as two virtual cores , thus performing multiple tasks simultaneously without activating the second physical core which would require more power from the system.
If both processors are active and using hyper-threading, those four virtual cores will compute faster. However, do note that physical cores are faster than virtual cores. The difficulty is that there is no blanket approach from Intel regarding hyper-threading on its CPUs.
In short, you'll have to check the individual CPU for its hyper-threading potential, as Intel appears to chop and change with each processor generation. One thing is for sure: the fastest Core i9 series does support hyper-threading. All of the latest Intel Core processors now support Turbo Boost frequencies.
Previously, Intel Core i3 owners were left out in the dark, forced to suffer with their regular CPU speeds. Turbo Boost is Intel's proprietary technology to intelligently increase a processor's clock speed if the application demands it. So, for example, if you are playing a game and your system requires some extra horsepower, Turbo Boost will kick in to compensate.
Turbo Boost is useful for those who run resource-intensive software like video editors or video games, but it doesn't have much of an effect if you're just browsing the web and using Microsoft Office.
The cache is the processor's own memory and acts like its private RAM. Upgrading to a newer CPU with a larger memory cache is one of the upgrades that will benefit your PC the most. Just like with RAM, more cache size is better. So if the processor is performing one task repeatedly, it will keep that task in its cache.
If a processor can store more tasks in its private memory, it can do them faster if they come up again. Ever since graphics were integrated on the processor chip, integrated graphics have become an important decision point in buying CPUs. But as with everything else, Intel has made the system a little confusing. Intel Graphics Technology is the umbrella term covering all Intel integrated graphics.
Within that, there are different generations of Intel integrated graphics technology, confusingly referred to by both series names and generational names.
Still following? The best advice for how to interpret these? One should look beyond the Core i branding and check the number of cores, Clock Speed, Turbo Boost and Hyper-Threading to truly understand the magnitude of power it generates.
Different processor families have different levels of efficiency, so how much they get done with each clock cycle is more important than the GHz number itself. Desktop chips follow a more logical pattern as compared to laptop chips, but many of the technologies and terms, we are about to discuss, such as cache memory, the number of cores, Turbo boost and Hyper-Threading concepts is same.
Similar is the case with the Mobile processors. Concepts and Technologies Total number of cores present: Out of all differences between the intel processor ranges, this is one that will affect performance the most.
Having several cores can also drastically increase the speed at which certain programs run. The Core i3 range is entirely dual core, while Core i5 and i7 processors have four cores. It is difficult for an application to take advantage of the multicore system.
Each core is effectively its own processor — your PC would still work slowly with just one core enabled. Having multiple cores means that the computer can work on more than one task at a time more efficiently. Skip to content.
