The Nehalem Preview: Intel Does It Again

Power Consumption
Built on the same 45nm process as Penryn, we expect Nehalem to have higher power consumption than Penryn but given Intel's target of a 1% increase in performance for no more than a 1% increase in power consumption per microarchitectural change - the results should be reasonable:
And reasonable they are; for a 20 - 50% increase in performance, total system power consumption only went up by 10%.

is it just me or does lga1366 bear more than apassing resemblance to amd's logo...if only they could have crammed it into 1337 pins - "nehalem - the 1337 chip"

I see that on the Daily Tech main page, the headline for this article now reads:"June 5, 2008
Post date on AnandTech's Nehalem preview, before it was ripped and republished on Tom's Hardware"
Does anyone know what happened? I cant find the same article on Tomshardware, I presume they took it down.

10 pages of comments and not one about the future of overclocking?No more FSB = no more overclocking??????
Enthusiasts might jump ship if overclocking usually brings 20% extra performance, all amd have to do is come within 10% on performance and below on price?

JebuzzzThis pretty much makes it pointless to purchase any high tier mobo and quad core today... It will be eclipsed in 6 months time...
Some of the numbers here make me wonder, "Are you f*cking kidding me?"

Anand, you could clear up some confusion if you could specify the version of windows you ran. The screen shots of some of your benchmarks show 64-bit Vista, yet your scores are inline with 32-bit Vista.... it makes a difference.JumpingJack - Friday, June 13, 2008 - link
Nevermind, page 2 shows 32-bit Vista... makes sense now. You should becareful when posting stock photos, the Cinbench reflects 64-bit.barnierubble - Sunday, June 8, 2008 - link
It appears to me that the Tick Tock cycle diagram is wrong.Conroe shooked the world in the second half of 2006, Penryn came in the second half of 2007, now 2008 we have Nehalem on the horizon set for the second half of this year.
Now that is 2 years between new architectures with the intermediate year bringing a shrink derivative.
That is not what the diagram shows; bracketing shrink derivative and new architecture in a 2 year cycle is clearly not fitting the reality.

Will the new IMC support ECC RAM? And if so, what are the odds the consumer versions will too? I've had a bit of bad luck with memory errors in the past. Since then I swear by ECC memory, even though it costs me a bit of performance. :)Natima - Saturday, June 7, 2008 - link
I just thought I'd point out that the Bloomfield chip reviewed (to be released in H2 2008) will infact dominate the gamer/high-end market.http://en.wikipedia.org/wiki/Nehalem_(microarchite...">http://en.wikipedia.org/wiki/Nehalem_(microarchite...
The smaller sockets will be for what I like to call... "office PC's".
And the larger socket for high-end servers.
A majority of custom PC builders will be able to buy & use Nehalems by the end of the year. Hoorah!

The article semi-implied that chips for the PC enthusiast would not be out until mid-2009. Just wanted to clarify this for people.
