What is icore and generations in laptop?
In: Technology
An intel processor has a name like this:
i7-9700K or
i5-8200Y
i7, i5 and i3 tell you the intended market segment for the CPU: i7 are performance models, with fully unlocked features. i5 are mainstream parts, with similar specs to i7, but usually lacking some features and slightly lower clock speed. i3 are cheaper parts, with fewer cores. Below i3 there are also celeron and pentium processors, which are the budget models meant for really cheap computers. On top of that, there’s now also i9, which is the high end with many cores.
Each year, intel brings out a new lineup of processors, which bring new features and better performance, occasionally more cores as well. This is the first digit of the number code: a 9700 CPU is from the 9nth generation. The number behind that tells you very little, other than more is usually better. Finally, the letter at the end tells you about special features: T or U means that they use low power, K means that it can be overclocked and H means that it has a more powerful GPU.
So when they tell you “9th generation i7 CPU”, you can assume that it’s a recent, fairly powerful CPU, without looking at the specs. If it’s “5th generation i3”, they’re trying to sell you five years old garbage.
While this is usually dependable, you should also look at the letter suffix of the model, since U CPUs in particular tend to be massively slower than their non-U counterparts.
