What is the difference between i3 vs i5 vs i7

Which One To Buy i3 VS i5 VS i7

i3 Or i5 Or i7

I love Intel as much as anyone. They make cool products, they engage in lots of community stuff, and I mean heck, But man, when it comes to confusing product naming schemes, I think Core i3, Core i5,Core i7 takes the cake. I mean, great question! 

What is a Core i7 479GK? What the heck does all of this even mean? We'll get to that. But first a bit of background about why we need product names for processors. Wouldn't it be simpler to just label them with how many gigahertz they run at and call it a day? Simpler, sort of, but at times actually even more confusing. For example, when the Pentium 4 launched an equivalently clocked Pentium 3 was actually faster because it could do more work with each cycle. 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 and rating products that way is about like rating the performance of a car based on what RPM the engine runs at. It's not actually a real indication of how fast the processor is! 

But it happened. Now one of AMD's attempts to move away from this started in the early 2000s with their P.R. or performance rating naming scheme where they're processors were given a four digit model number that enthusiasts believe was based on the performance AMD felt that they delivered compared to an Intel CPU of that clock speed. But this fixed nothing. They were still indirectly naming according to clock speed, and 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 because Intel needed to shift their marketing away from frequency. So here's what we have today. Other than the very bare bones Pentium skews, a Core i3 will be your most basic option with two processing cores and hyper-threading, ore about this feature here, for better multi-tasking. It will have a smaller cache,it'll consume less power, and it will generally perform worse than the Core i5, but it'll cost less. Which leads us to the Core i5. 

I wish I could say it was as simple as, well, Core i3s have two cores and core i5s have four cores. The number of cores equals N minus one where N in the number after the little i. (buzz)But it's not. Mobile Core i5s have two cores and hyper-threading while desktop ones,mostly, have four cores and no hyper-threading. But what they all have in common is improved on board graphics and turbo boost, more about this feature here, for temporary performance enhancements when your system needs a little bit more umph. And with umph in mind, Core i7s. 

Number one, all Core i7s have hyper-threading for heavy workloads and number two, that's the noise your brain is gonna make as I finish my explanation here. A Core i7 can run anywhere from two processing cores in an Ultra book all the upto eight in a workstation. It might support anywhere from two sticks of memory all the way to eight and it can have a TDP all the way from around 10 watts all the way to 130 watts. So there is a ton of variety here, and that's for a reason. Core i7s tend to have more cache, faster turbo boost, and better onboard graphics than the lower tier processors. And I guess other than that, 

The best summary I can give is this. A Core i7 represents thebest thing Intel could build for a given use case with the biggest drawback being the higher price tag. So when you boil it down, that's all the i, what ever numbers represent. Good, better, best within a given segment. Beyond that on their own, they're pretty much meaningless. The numbers and letters afterward sort of mean something if you use the guide from before. But the safest way to shop is to dig around in ARK and look at the features, core counts, and clock speeds of the CPUs you're comparing to figure out how they stack up, with the good news being that as long as you compare within one brand and within the same product generation, those metrics will actually mean something.
