Why do intel chips vary in performance???

post #1 of 30
Thread Starter 
Just wondering what would cause a cpu to vary in performance so different if they are all made with the same schematics. Ie i7-920 to 960 all have the same architecture.

explain. because i heard when the come out of the factory their speeds are tested and then labeled according to what they get. why would this happen in a chip. explain scientifically

920 is clocked at 2.6GHz, and 960 is clocked at 3.2GHz.

Think of as 2 911 Porches. One is limited to 130 MPH, and the other is limited to 150 MPH.

OCing the CPU will get your speeds up.

Think of as 2 911 Porches. One has a turbo, and the other has 2 turbos.

Same car, but faster.
Crappy analogy.

Take the same two cars with the same turbo setup.
One is ECU limited from the factory to supply a certain amount of boost.

Both cars have the same potential, but the manufacturer makes more money by artificially limiting performance.

I remember reading on this very site that the 950 has a worse memory controller than a 920/930.

How can they be the same then?

This, by limiting what the chip does they can sell it cheaper as to fall in-line with pricing/performance. The cheaper chips allow for a larger target market.
