What is a Core i3, Core i5, or Core i7 as Fast As Possible

- I love Intel as much as anyone.

They make cool products, they engage

in lots of community stuff, and I mean heck,

they're even a major sponsor of my other channel.

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 onboard 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 Ultrabook all the up to 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 the best 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, whatever 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.

Speaking if mean, Fractal Design is back buying up

all of my advertising inventory

for the sole purpose of making me do stupid crap

on camera for y'all instead of talking about

the great quality and clean Scandinavian design

of their PC cases, power supplies, and cooling products.

Mind you, I don't know who to be mad at this point,

because it was you, not Fractal

who posted, let's make him do the sponsor spot

on helium on their Facebook page!

I mean, thanks a lot guys!

I mean, genuinely thanks for watching, guys.
