45nm question?

JLV2k5 · 01-10-2008, 12:29 AM

What exactly is the spec of 45nm or 65nm or whatever for processors? I know the 45nm are better. Someone reveal this to me please. Thank you.

Anyone? I heard there was a new line of this type of processor coming out soon. Comparable to the Core 2 Extremes that are out now, they are 45nm. I just don't know what this stat is exactly. Thanks

45nm. The processors run cooler, use less power, and have a 66% increase in cache.

I've always thought that the '45' in 45nm was the size of the wire that connected each individual transistor. Now that I think about it, that's probably not right. Can anyone correct me?

Do any of you guys know if the cost of the CPU will go up if I were to buy a 45nm to a 65nm. The reason is because if they go up alot I think I will just buy a 65nm one now.

the projected price on a dual core 45 nm processor is about the same price that the current 6750 is on newegg right now, so your best bet is to wait

Thanks. A lot of system builders are speaking of waiting another month or two to buy CPU due to the release of more 45nm chips. If anything, the 65nm processors will decrease in price due to being overpowered by the 45's. I am not planning on building a machine until this summer, so im sure i will end up with a 45 nm.

Thanks for the information.

45nm is the size of each transistor.

I was curious about this too. When I heard it I immediately thought nm must stand for nanometer (What else?). Nanometer being a measurement of distance, and such a small one at that, must have had something to do with the processors internal circuit. After eading the wiki article they explain it's the width of a transistor on the wafer, as omega says. There are also articles about manufacturers making 15nm, and even 13nm wafers....but it doesn't seem that they are commercially available yet.

Thanks guys.
