Intel’s 45nm– Hitting 4 GHz with Air Cooling - Overclock.net

Rarely have things looked as good for Intel as they do right now. Exactly 18 months after their introduction, Intel is updating its highly successful Core 2 CPUs. The chipmaker is shrinking the structures from 65 nm to 45 nm and is already preparing the next step – the transition to the Nehalem platform. However, that’s all still in the future and won’t come to pass until the end of 2008, at the earliest.

Even though the number of transistors has increased from 586 million to 820 million, power consumption has dropped by 39%

Wow.

Get a new GPU from NVIDIA, then one of these babies, and you are one happy camper~!

wow they were really scared to push a measly 1.4375 volts into the cpu??

I think its because these new chips are made of a smaller architecture... So 1.4375 might be like putting 1.6v on the 65nm chips...???

Just a thought...

Great post!
I found this very interesting point about the FSB speeds:

The Core micro-architecture was designed in such a way that it only needs to access the main memory very rarely. This is achieved by letting the processor loads data speculatively. The larger 12 MB L2 Cache (2 x 6 MB) reduces the processor’s dependence on the RAM even further.

This is why increasing the speed of the northbridge, which contains the memory controller, by ca. 25% to 400 MHz (1600 QDR) has practically no impact. A performance increase of 0.5% across our benchmark suite compared to FSB1333 is completely unnoticeable to any user.

Thus, the only thing a higher FSB will get you is a minor increase in power consumption by the northbridge as well as potential instabilities on the P35 and X38 chipsets, neither of which officially supports FSB1600.

At least in the desktop segment, it is obvious that FSB1600 will be offer more marketing potential than actual performance benefits.

I wish Tom knew that a: ( , ) does not equal a: ( . )

This looks very promising

I'll be sure to buy a quad core 45nm CPU when the time comes

Umm... huh? How is that obvious? Many of us here run 1600FSB without a hitch... I'm running at 1669 completely stable with a 680i no less, without any problems. Running 2000FSB is a problem, at least for me. lol

......in other countries everything is backwards. $2,000.00 to us is $2.000,00 to them =/ so i bet they say "i wish americans knew that a ( . ) doesn't equal a ( , )".......

rofl, i dont think so, im pretty sure a , when talking over $100 is normal (im in australia)

$100.00
$1,000.00

ect
