The Core i7 980X Review: Intel's First 6-Core Desktop CPU

The Heatsink
This is Intel’s retail LGA-1366 heatsink:
And this the heatsink that comes with the retail Core i7 980X:
It’s much larger than the standard i7 heatsink, but not quite as large as the tower coolers from Thermaltake or Zalman. It’s fairly quiet but at full speed it does have an annoying whir to it. Thankfully other than in a no-POST situation, I never heard it at that speed.
Installing the new heatsink is both more and less pleasant than the standard LGA-1366 cooler. You stick a plastic plate to the back of your motherboard that the heatsink screws into (that’s the pleasant part):
The screws are difficult to access thanks to the size of the heatsink itself, especially if you have a motherboard with heatsinks that crowd the CPU socket (and that’s the unpleasant part).
Currently the new heatsink is exclusively for the i7 980X. The rest of the lineup gets the plain old coolers.

it's a 2-p4 mcm at at a lower node with a lotof improvements over the older p4 manufacturing processes.
if i absolutely had to have netburst, that's what i would want.
i think it's really nice that Anand includes it in the comparison, because it gives a sense of history to the article, and it shows how much faster CPUs have gotten in such a short time.

Yep. It might be based on P4, but you can't really considered a P4. It was based on two cedar mill cores rather than smithfield with double the cache and a 200mhz bus speed jump.Dadofamunky - Thursday, March 11, 2010 - link
And exactly the same NetBurst architecture otherwise. And I'm sorry, but seeing that POS coming up with 40% against Gulftown signifies either one of two things: Gulftown isn't that much faster; or, the SysMark software distorts the relative performance results. That isn't a realistic portrayal of 'history.' SysMark 2007 badly needs an update. It isn't a realistic tool for the 4-to-6-core world.danielkza - Thursday, March 11, 2010 - link
Weird, other sites managed to squeeze up to 4.4GHz of the 980X on air, and 4.7GHz on WC. I thought initially of different stability requirements from both parts, but bit-tech ran all their benchmarks at both 4400MHz and 4720MHz. Maybe Anand's DX58 isn't holding up so well after all.http://www.bit-tech.net/hardware/cpus/2010/03/11/i...">http://www.bit-tech.net/hardware/cpus/2...-core-i7...

Anand only used a stock cooler to test. The intel coolers never have much head room in them. Luck of the draw in both mobo and CPU might be a factor but so is bit-tech's better cooling.chrisfam - Thursday, March 11, 2010 - link
Tomshardware got a 4.13 Ghz overclock with 1.4v and with Enhanced SpeedStep and Turbo Boost enabled. Neoseeker got a 4.16 Ghz overclock with just 1.35v. And both of these were with the stock heat sink.Anand Lal Shimpi - Thursday, March 11, 2010 - link
I've been working on a follow up to go deeper into our overclocked numbers. A motherboard swap later and a little bit of work appears to be paying off...I'm over 4.1GHz already :-)Update soon!
Take care,
Anand

Updated overclock (4.13 Ghz, 1.359V) is much better. Thanks for the update.Rajinder Gill - Thursday, March 11, 2010 - link
That's right, 3.7-3.8GHz is the full load limit of Intel's stock cooler with these beasts. We ran out of time to really push, but I'm sure we'll find out what these chips can do in due course.regards

Is the new tower cooler an improvement in any way over the old one? Is it quieter, as it doesn't seem to offer more OC headroom.Also, how does the CPU power consumption increase by 130W at load over idle, while system consumption only goes up 90W?
