Are i7 laptops better than i3 or i5 laptops?
Generally yes, but it depends on exactly which i3, i5 and i7 you are comparing.
Let me give you an example of how things can get confusing:
Currently, Intel sells the dual core i7 8500Y for ultrathin laptops. They also sell the i3 8100H which is a more powerful quad-core processor than the i7 8500Y and has more powerful integrated graphics.
The i3 8100H is also cheaper than the i7 8500Y, so a laptop with it will be cheaper too. So why is this? It’s good.. let me explain:
When looking at Intel processors, you can’t just look at the letters and numbers of i3, i5, i7 and i9, you also have to look at the other numbers and letters.
Here’s how to build model names for Intel Core processors. The most important thing to look at here is the generation indicator and product line suffix.
In the case of the i3 8100H, the generation indicator is 8, and one for the i7 8500Y, which means that they are part of the 8th generation of processors from Intel.
Now, let’s take a look at the product line suffix which can include none, one, or in some cases two letters. There are also cases where there are letters and numbers. Here are the most common suffixes for Intel laptop processors.
As we can see, “H” means that the processor has high graphics performance. Sometimes they put “H” only to indicate that the processor consumes more power than, say, the “U” processor.
HQ appears from time to time on some quad core processors without the “Q” for some reason only Intel knows about. But as you can see, the Y series of i7 8500Y is a series of “very low” mobile phone processors. This system has up to and including the eighth generation two cores that work well with hyperthreading that can use as little as 5W of power.
That means much better battery life and it means that it runs so well you can run the CPU without worrying about the chassis being critical. Gen 10 will bring 4-core processors to the Y series for the first time. The U-series up to the 7th Gen also had two cores at most, but now they are now going with 4 cores, and next year, there is even talk of a 6-core.
The U-series TDP is usually 15W, so a little than the Y series, but still works well. The i3 8100H is a “heavy” processor with a TDP of 45W.
This means that it is intended to be aimed at the most powerful, but large, desktop computers. i3, i5, i7 and i9 processors with H suffixes, and especially HK, are often found in large and large working laptops or gaming laptops.
I hope this helps you. Intel’s naming scheme can be confusing, so it’s understandable that choosing the right laptop can be tricky at times. Usually a higher number means better, but not always.
