CPU Binning

[stan92]

How does Intel sort out which cpu is a celeron, pentium, i3, i5 and i7? as they are all from the same wafer?

Generealy the cpu cant handle the extra load from cores or hyper threading without a ton of voltage so they just turn those off and call them what they are.

[ANUPLUCIFERGAMER]

maybe they have robots do that for them. or the latest lga method or something. if i'm right

[stan92]

so they test them in some magic way before they go into the box and shipped off? @Hunter259
 

@ANUPLUCIFERGAMER whats the latest lga mean?

Well at least you didnt make new topics about it.

Lets say intel makes a bunch of 4770k chips. Say  some of them aren't very stable with hyperthreading and so those becomes i5s. Say some of them are not good with 1 or 2 cores those chips become i3s. then the pentium are cpus that don't handle 1 or 2 cores and hyperthreading and the celerons are like the pentiums, but can't handle as high of a clock speed.

LGA technology of intel. they don't use those pins as AMD still uses it.

More specifically, they fuse off the extra stuff that doesn't work.

thankyou @Kirihuna

@Emperor_Piehead so my 3570k could be nearly as good as a 3770k?

The pins are in the CPU socket.

Not necessarily.

[stan92]

could someone elses be nearly as good? or are their bold lines of difference in their testing? does anyone know what is involved in the testing?

[Godlygamer23]

What do you mean by "nearly as good" anyways? Performance or overclocking?

[Leonard]

I was told that the ones nearest to the center of the wafer are the best of that crop and they just put them aside  for k sku and also different wafers have better characteristics than others so there center CPUs will overclock better than others.

[stan92]

@Godlygamer23 purely performance, no overlocking...

@Leonard so there are seperate wafers for celerons, then another for pentium and another for i3, another for i5, and another for i7's? also how big are the wafers? and are they cut into bits?

[s3ns3]

thankyou @Kirihuna

@Emperor_Piehead so my 3570k could be nearly as good as a 3770k?

or bad as a celeron ? it does have the same ivy core ... are you scared ??

 

you got what you paid for.so its just as good as any i5 ivy. at stock at least

[stan92]

@s3ns3 , how can i tell how good it is against other i5 3570k's stock?

[s3ns3]

well ,you can tell by looking at the name. if someone has an i5 3570K at stock,then it will be just as good as yours. because  the cpu is the same.it has the same jigahertz.they run the same cache. same architecture. same model . where am i going with this ?

[stan92]

@s3ns3 ok thankyou

I would thing there are different wafers for different line of CPUs from both vendors and the i3, i5, i7 thing is done on the same wafer but if a CPU is not good as a quad core they just "zap " off two cores and make it a dual core. I have no idea how big the wafers are and yes they are "cut into bits" from the silicon wafer to make each CPU. What i would like to now is how to check if a random CPU is close to the middle of a wafer. If you are really interested about the topic you should check out PCPER website for articles.
