The U rating is only for mobile processors. KĪs you can see, the model number will typically be followed by one or a combination of the following letters: U, Y, T, Q, H, G, and K.
What Intel's Model Letter Suffixes Mean: U vs. Now while this doesn't make a huge amount of difference when you're choosing between an i3, i5, or i7 CPU, each of these CPU types comes with a different Hybrid Core configuration. This ensures that your computer makes efficient use of the available processor power. For example, when you're gaming, the P-Cores will handle your game while the E-Cores will work on background tasks, like your streaming app.Similarly, P-Cores are best used for single-thread and lightly-threaded tasks, like games and productivity apps, while it designates highly-threaded apps to the E-Cores. However, with the 12th generation Intel Core, we now get different Performance and Efficiency cores.What this does is that the processor uses Performance Cores (P-Cores) for priority apps running in the foreground while the Efficiency Cores (E-Cores) are used for background tasks. Intel's 12th Gen CPUs added another consideration for would-be users: Hybrid Cores. They may also come with a larger CPU memory cache than their counterparts, enabling faster overall performance. Most Core i9 CPUs are now 16-core beasts (doubling the octa-configuration of the previous generation) and come with a very high clock speed, enabling them to perform to a very high standard for prolonged periods.

The Intel Core i9 series is Intel's extreme performance line. The latest CPU generations have another tier above Core i7, the Intel Core i9. Each family, in turn, has its own line of Core i3, Core i5, and Core i7 series of processors. At the time of writing, Intel has launched its 12th-generation CPUs, named Alder Lake. Intel releases "families" of chipsets, called generations. Quad-cores are usually better than dual-cores and hexa-cores better than quad-cores, and so on, but it isn't always accurate depending on the CPU generation-more on these differences in a moment. Again, the Intel Core i7 CPUs outperform their Core i5 counterparts and are much faster than the entry-level Core i3 CPUs. The latest Intel Core i7 CPU generations include quad-core, hexa-core, and octa-core, and 12-core configurations. The latest i5 generation includes 10-core CPUs. Older generations of Intel Core i5 processors had a mixture of dual- and quad-core processors, but the later generations typically feature a quad- or even hexa-core (six) configuration, along with faster overclock speeds than the Core i3. It is a similar story for older Intel Core i5 CPUs. Older Intel Core i3 series had only dual-core processors, but more recent generations have a mixture of dual- and quad-core CPUs. Things go a little deeper.įirst, Core i7 does not mean a seven-core processor! These are just names to indicate relative performance. The trouble is knowing what to expect within each tier. An Intel Core i7 is better than a Core i5, which in turn is better than a Core i3.
