DIFFERENCE BETWEEN 90nm and 0.13

post #1 of 8
Thread Starter 
when buying a processor what the difference?? now i have a p4 2.6 and its 0.13.

the one i just ordered is p4 3.4 90nm.

good or bad?? what to look for??

90 micron and 130 micron is the size of the transistors used. Smaller, in general, means that more can fit on the same size die,generate less heat. This *should* make for higher clocks due to lower heat if everything else was held constant. They use less power,also.

That's good. It should mean that it's smaller so it uses less voltage and creates less heat. Presscotts still create heat though...
Not bad at all...

The Pentium 4 2.6 you are talking about is built on the 130 nanometer process (1 X 10 to the minus 9, or a billionth of a meter).
You have said that it is 0.13, thats in picometers (1 X 10 to the minus 12 or a trillionth of a meter)

The Prescott/Prescott 2M are built on a 90nm process or 0.09 picometers.

The smaller the die size the more transistors are able to fit on it. Decreasing the die size also allows for increased clock speeds and a reduction in voltage and thermal output. However for the Prescott the temperature actually increases, this is because the processor itself is actually quite unefficient in the temperature departement. Still a very good processor and I love them but they are just extremely hot and it can get annoying in that departement.

The 3.4 is a good processor and will allow you to select a x14 multiplier on a compatable board. This would allow you to hit very high bus speeds.
I would be watchful of the temperature though as it can get very high, keep it under 65C to be on the safe side

yea, basically the main difference (noticable difference) is that it uses less power and runs cooler. in general its better to get the smaller one, because heat is bad.

I might be incorrect, but it sounds like you're implying that the 90 nm process and 130 nm process is referring to the die size. If I'm reading that wrong,then forget this post. If however, you are implying that, that is incorrect. The 90 micron and 130 micron process is describing the transistor size. I became quite familiar with this while being an intern at National SemiConductor here in Puyallup,Washington (was formerly Matsu****a before NS bought the fab)

I am not refering to the die size of the processor (even though it did look a bit like it, need to fix up the post later). The 90nm/130nm does mean the size of the transistors i.e. the smaller the more can be put on

can we fit miniature cute widdle cows on the die too? i love cows..
