45nm question?

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
 
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. :)
 
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.
 
Yeah I heard the release date was soon. Thanks for the offical notice. I'll be waiting for the summertime regardless, so hopefully I'll end up with a better 45nm processor.
 
what i dont understand is why 45nm is any better?

is it cos you can fit more into the same size cpu or what?

and then couldnt you just use a bigger cpu?

hmmmm.

45nm is better for consumers because it uses less electricity (important in mobile devices), which in turn also produces less heat.

Manufacturers prefer 45nm over 65nm because it allows them to fit more CPU dies per wafer, which increases production yields while lowering the average price for a processor.
 
hey i have a question about the 45 nm procs, what chipset is needed to use them? i'd hate to buy a gigabyte p35-ds3l just to learn that the processor wont work lol

It will work, with a CMOS flash. For what I know:

P35's
P31's
X38's

Maybe 780i, I'm not sure :(

The P35 will work for sure, or else my P31-DS3L wouldn't have some in with a "45nm Ready" tag :P
 
Will this 45nm business be released on the quads anytime soon as well?...when?...after the dual cores?

If so, how much should we expect to see them selling for?...does this simply depend on all the usual factors?...i.e. SPEED!

The QX9650 is already out. Just under $1,000 at newegg. The others were suppose to be released this month, but Intel delayed the release. Some believe around Feb-March.

Here's an old price list. The prices will probably be a little higher than what's seen in the chart:

Ahh, thank you I didn't realise the QX9650 was 45nm.

Overclockers UK are selling the QX9650 at £700, which is $1400:

After converting prices from dollars to pounds, almost everything still seems to be much cheaper in the states. $1000 would be ~£500, which is still a big £200 difference. Is this cos you guys get the technology first?

I'm taking it the Q9550, Q9450, and Q9300 haven't actually been released yet then?...this is what you refer to as Feb-March times? The prices for them listed there don't seem that much higher than the Q6600, which over here is selling for £160 ($320), and the clock speeds are higher for the price, and being 45nm, the cooling will be better too?...maybe it might be worth waiting. How much higher d'ya spose the prices might go?

Thanks
