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

Overclocking - Updated!
With six cores and 12MB of L3 cache on a relatively new 32nm process, it's not surprising that we weren't able to push our Core i7 980X too far. At stock voltage I was only able to reach 3.5GHz with turbo mode disabled using the stock cooler. I could get the system into Windows at ~3.7GHz, but not stable without additional voltage.
3.5GHz - Max overclock with stock cooling and stock voltage
Giving the chip extra voltage let me go up to 4.13GHz without sacrificing stability.
4.13GHz - Max overclock with stock cooling at 1.359V

Please test 7-zip compression with 7z 9.x which support lzma2 algorithm that can support 16 cores. It runs much faster than 7z 4.x on my i7 920.just4U - Thursday, March 11, 2010 - link
I've had the 920 for 13 months now and seeing this review makes me want to do a little dance. (I also have a PII 920 I like very much) The 920 holds up well I think overall.Some will b e horrified to know that I run it at stock. It can go quite high and I've got it set up with aftermarket cooling but I haven't really found a need to OC it as it. Someday I am sure I'll run it into the ground but not yet! A good purchase over a year ago, and still a worthy buy today.. or the 930 I guess since that's it's replacement.
Looks like it will be awhile before I move to 6cores. I wonder what AMD's offering will be like.

Ill be your dancing partner. It seems Intel is having a problem cranking up gaming performance after the Core2 series compared to other categories. Not having a fat cache limited Bloomfield performance and it seems a slower L3 cache is dragging down Gulftown.I'm not expecting the 47% gains like in ray-tracing, and in general Bloomfield/Gulftown has increased gaming performance; however, there are situations where a previous generation has a more suitable architecture. It would be nice to have a "BAM! CHECK ME OUT!" product such as Conroe where it absolutely swept everything, and for current gamers, Gulftown is not that. I'm sure however in the future having the extra cores will lend themselves more improvements though.

Come on people...You cant judge this CPU with games. It should be pretty obvious it wasn't going to do much in that area anyway.
Theres still loads of games that are poor at making use of quadcore let alone 6 core. Infact every single game i have uses less than 30% CPU usage on my 4.1GHz i7 920. Alot are under 15%. Thats just pathetic.
And only recently has quad started to make a decent difference over dualcore with some games.
I'm sure this CPU will have a longer life span for gaming performance when games actually start using PC CPU's better in the future, but thats probably years away as most games are console ports these days which are made in mind with vastly slower console CPU's.

I disagree. I don't thinkg this cpu will have a longer life span. My thinking is that when the current generation of cpu's finally start showing their age and can no longer cut it then you'd be upgrading anyway. Don't really matter if you have a 920, Q9X, a PIIX4, or even the 980X..... They are just that fast. Sure, some are faster then others but were not talking night and day differences here.
As an enthusiast and as someone who builds a great deal of computers I will likely have a new cpu long before I really need it. But that's more of a question of "WANT" rather then "NEED" You know?
Those sitting on a dual core and thinking of pulling the trigger on this puppy will be the ones who benifit from a purchase like this. The rest of us ... mmm not so much.

They can very well judge the CPU based on games, if games is what they do and the reason they'd consider upgrading. My most taxing application is gaming, and so I see little reason to move beyond my overclocked E8500.Otherwise, it's just trying to find a need for the solution, rather than the other way around. If I spent time doing tasks this CPU shined at, I'd be very excited about it.
Further to my point, I disagree with the article stating this is the best CPU for playing WoW. I would argue that a CPU costing 1/10 as much that still feeds your GPU fast enough to hit the 60 fps cap is a better CPU for playing WoW.

When a program like SysMark shows a crappy P4 getting 40% on average against the latest and greatest, it's definitely time for a new benchmark program. There's no way that P4EE ever comes that close in the real world. It's time to drop SysMark rom the benching suite. It's like using 3DMark03 for video card benchmarking.JonnyDough - Thursday, March 11, 2010 - link
That would be true, except that it isn't a Pentium 4, and this synthetic benchmark isn't supposed to be accurate, just give you an overall idea of how a CPU fares in relation to others. The Pentium 955 in question is a 65nm Presler core, not an old socket 478 chip...Dadofamunky - Thursday, March 11, 2010 - link
It's helpful to know what you're talking about before you correct me. Presler IS P4. and I noted it as a P4EE. And of course ignoring my point is not a good way to refute it.piroroadkill - Thursday, March 11, 2010 - link
Presler IS a Pentium 4
