Black Friday i7 LAPTOP BUYING GUIDE

What is a core i7 4790k, what does all of this even mean? As a customer, I would expect the product with the higher number to be the better one and therein lies the problem not all megahertz and gigahertz are created equal. In the early 2000s PR or performance rating naming scheme was introduced, where processors were given a four-digit model number. Enthusiasts believe this was based on the performance. It wasn’t until Intel introduced the core series, a line of CPUs that dramatically outperformed their predecessors at much lower clocks, that the megahertz war ended. Intel needed to shift their marketing away from frequency so here is what we have today.

BLACK FRIDAY CORE i3

A Core i3 will be your most basic option, with two processing cores. For better multi-tasking, it will have a smaller cache, it will consume less power and will generally perform worse than a Core i5, but it will cost less.

BLACK FRIDAY CORE i5

This leads us to the Core i5’s, they have two cores and hyper-threading while desktops mostly have four cores and no hyper-threading. But what they all have in common, is improved onboard graphics and turbo boost.

BLACK FRIDAY CORE i7

All Core i7s have hyper threading for heavy workloads. A Core i7 can have anywhere from two processing cores in an Ultrabook, all the way up to eight in a workstation. It might support anywhere from two sticks of memory, all the way to eight. It can have a TDP anywhere from around 10 watts, all the way to a hundred and thirty watts, so there is a lot of variety. Core i7 tend to have more cache, faster turbo boost and better onboard graphics than the lower tier processors. The best summary I can give is a core i7 represents the best thing Intel could build for a given use with the biggest drawback being the higher price tag. So, when you boil it down, that is all the i numbers represent, good, better, best within a given segment. Beyond that, on their own, they are pretty much meaningless. The numbers and letters afterwards mean something if you use the guide from before. The safest way to shop is to dig around and look at the features, core counts and clock speeds of the CPUs. You are comparing them to figure out how they stack up. As long as you compare within one brand and within the same product generation, those metrics will actually mean something.
