If your CPU has six cores….you get the idea. If your CPU has four cores, it can handle four threads at once. If a CPU is a dual-core, then supposedly only two threads can be served simultaneously. In normal circumstances, only one thread can be served by one CPU core at a time. Hyper-Threading Credit: SuppliedĪlthough the analogy isn’t perfect, Hyper-Threading is basically the equivalent of something like turbo-boost when it comes to increasing the power of your CPU’s cores.
Meanwhile, 8th-Gen Coffee Lake i5 and i7 CPUs boast double their fourth-gen counterparts at 12MB and 16MB, respectively. In contrast, Intel’s more modern 8th-gen Coffee Lake i3 CPU feature either 6MB or 8MB. Intel’s 4th Gen Haswell Core i3 processors had either 3MB or 4MB of cache, Haswell Core i5s had either 4MB or 6MB of cache and Haswell Core i7 CPUs had a hefty 8MB of cache, except for the i7-4770R, which had only 6MB.

This is one major reason why an i7 outperforms an i5 - and why an i5 outperforms an i3. If RAM's value as a component is billed around its ability to minimise interaction with your PC's hard drive, the value of your CPU's cache is that it minimises interaction with your PC's RAM.Īs you might be able to guess, a CPU with a larger cache allows for more data to be accessed faster. A CPU’s Cache is just like RAM, only faster - since it’s built into the CPU itself. See, whenever a CPU finds that it keeps on using the same data over and over, it stores that data in its cache. Without them, the CPU would have to keep on rely on your hard disk drive for everything, which would slow everything down and causeeven simple tasks take a lot longer. Intel initially spent $250 million on the campaign, which targeted consumers rather than industry insiders.Īnother thing that sets Intel’s i3, i5 and i7 apart is cache size.īoth your computer’s RAM and its CPU cache serve as holding areas for frequently used data. Cache size Credit: Intel The Intel Inside marketing campaign began in 1991. An 4th-Gen Haswell i3 CPU like the Core i3-4330 has a higher base clock speed of 3.1Ghz.įortunately, since none of Intel’s Haswell Core i3 CPUs have Turbo Boost, the i5-4570T can outrun them whenever it needs to.īecause all of Intel’s Core i5 and i7 processors are equipped with the latest version of this technology - Turbo Boost Max Technology 3.0 - all of them can outrun any Core i3. Using the Core i5-4570T as an example, its maximum allowable processor frequency is 3.6GHz while its base clock speed is 2.9Ghz. This includes the number of active cores, the estimated current consumption, the estimated power consumption and the overall processor temperature. The maximum amount that Turbo Boost can raise clock speed at any given time is dependent on a number of factors. Intel’s Turbo Boost feature allows a processor to dynamically increase its clock speed whenever the need arises. Read more What laptop should I get?
