Whats the difference between 45nm and 65nm processors

[makaveli-313]

So i recently asked about new processors and was told about these 45nm version of the same old dual core's.So far i know that because of less nm it overclocks higher

Not saying that better overclocks isnt awesome but is there any other advantage of buying a 45nm based processor compared to the older 65nm ?

Thanks in advance

They run cooler and they are faster than the old models. Not quite sure, but they should also use less energy than the earlier generation.

They do use less power and therefore produce less heat

read this review its really good and explains in detail the differences.

The problem is that the cheaper 45nm quad cores have a fixed multiplier of 7.5 and 8x, which would make them a bit less interesting for overclocking, even though they could probably handle 4ghz+. You'd need a FSB of 500+ to reach this however...

If we could only convince Intel to sell processors with unlocked multipliers at prices we could afford...

I agree! One of the fun things from years ago was easily being able to unlock multipliers

[DainBramage]

It's too bad Intel won't copy AMD and release some previous generation chips unlocked for low money. Can you imagine the fun we could have with some unlocked Conroe's?

That's what intel is afraid of.

alrit thanks guys

so they lock it on purpose? or is it because of warranty/gurantee/life expectancy issues with the chip?

The FSB is 1333 on a 45nm...making it faster than a 1066 on a 65. The e8400 is a bargain at $200. Agree?

[splave]

agree, but dont dont think the 45nm isnt going to run hot because it does lol 1.4v seems to be the limit whereas 1.55v seemed to be the 65nm limit. Then again you are starting at 1.125ish vs 1.3ish

[rupchurc]

Over all though the new 45nm are better then the 65nm, but by how much may not be as big as it sounds. But I do here that the e8400 are awesome!

Different processor architecture also supports different bios programming and features. (64 bit, 3d now, etc.) Bad examples but you know what i mean

Temp is only the measure of resistance basicly. Running at the same speed/temp with less power is a + for some. but not for me since my apartment includes utilities. Hello 45 minute burning hot showers everyday lol and me and all my roomates pc's running 24/7.

Margins like these need time to grow apart but they will.

I dont think they ever lock multipliers for this reason, only so people will actually pay extra money for the same chip but in a higher chip price range. Like how the e6600 and e6700 are exactly the same with different multi's but for a long time were more than 100$ difference in price.
