PAR2 Multithreaded Archive Recovery Performance
Par2 is an application used for reconstructing downloaded archives. It can generate parity data from a given archive and later use it to recover the archive
Chuchusoft took the source code of par2cmdline 0.4 and parallelized it using Intel’s Threading Building Blocks 2.1. The result is a version of par2cmdline that can spawn multiple threads to repair par2 archives. For this test we took a 708MB archive, corrupted nearly 60MB of it, and used the multithreaded par2cmdline to recover it. The scores reported are the repair and recover time in seconds.
An application needs to be more than multithreaded to take advantage of the 980X, it needs to demand more than four threads. And our PAR2 test is pushing it as is, there's no advantage to the 980X here.
WinRAR - Archive Creation
Our WinRAR test simply takes 300MB of files and compresses them into a single RAR archive using the application's default settings. We're not doing anything exotic here, just looking at the impact of CPU performance on creating an archive:
Our WinRAR test takes advantage of the larger L3 cache and thus we see roughly a 9% performance advantage for the 980X compared to the 975.
Microsoft Excel 2007
Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.
If you're running any sort of computationally intensive Excel macros, the 980X will deliver. The financial market just wet themselves.
Sony Vegas Pro 8: Blu-ray Disc Creation
Although technically a test simulating the creation of a Blu-ray disc, the majority of the time in our Sony Vegas Pro benchmark is spend encoding the 25Mbps MPEG-2 video stream and not actually creating the Blu-ray disc itself.
Even when the application doesn't scale perfectly with core count, we still see some impressive gains. Our MPEG-2 Blu-ray creation test showed a hefty 20% performance improvement over the 975. If you do any sort of video encoding or Blu-ray authoring, the 980X is perfect for you.
Sorenson Squeeze: FLV Creation
Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.
FLV authoring shows another healthy gain of 30% over the quad-core 975.

[QUOTE]With up to 6 cores running at 3.46GHz, Gulftown is not only the fastest CPU in Intel’s lineup, it’s also the fastest quad-core Intel makes.[/QUOTE]I think you meant to say it's also the fastest "single-core" Intel makes.

And for only one thouuuuusand dollars! What a deal!!
lol yeah, anyone who spent $999 on an X58 CPU can now spend $999 on a new cpu 18 months later. $2000 for two CPUs in the course of 18 months. How you can spin that as being a good thing boggles the mind. What a waste!

Well, maybe you spent the ~$280 or so on a 920 in November 08, which you could now upgrade to the 980X if you wanted. Considering Intel's past history of supporting new processors on older motherboards (see, for example, P965 and Penryn) it is nice that this is supported, even if the upgrade is extremely expensive.BelardA - Thursday, March 11, 2010 - link
Kinda sad and funny... when core 2 came out, it destroyed the P4 line and of course kicked AMD down bad.Even todays $65 intels and $45 AMDs (running about 2ghz) are still faster than those older Pentium EE chips. And what was sadder back then was that even AMD's $200 CPUs were still faster than the $1000 intels... unless your were doing 3D work and encoding video.
*sigh*
Thanks to intel's back-room deals with the major PC companies, the illegal activities has hurt competition. AMD is doing better today, but have little to work with. And we see what the lack of competition does such as ATI vs. Nvidia.

Why they keep the CPU frequency so high? All consumer quad cores go higher than 2.5GHz??? I really like Opterons, low frequency with more cores.Seriously I hope Phenom VI (I made it up, they may call it something else) could have a model of 6 cores with each running 1.2GHz.
My own usage is mostly programming in JEE + documentation, so I need more cores but not that fast, so I could save a few bucks on my electricity bill in a year. :)

You can always underclock/undervolt if you don't need the performance from the extra speed but want the power savings.Note that this is the "Extreme" version, so it makes sense to have the fastest speeds possible. The mainstream versions that are coming will probably have lower clock speeds.

Maybe I missed it - but would this have any predicted implications on the 920 price over this year span?I'm rebuilding a rig a component at a time and Im wondering if there would be much variance if I picked a 920 now or in Q4

"The first Core i7 did not power gate its L3 cache, Lynnfield added it and Gulftown has it as well."THANK YOU ANAND!!
No wonder this is my #1 favored site. :D

I don't know about anyone else, but I would have liked to have seen how this chip fares to overclocks of Intel's other Core i7 series. While I'm sure many people don't bother overclocking, I would wager that most people who visit this site do, and probably bought into the Core i7 920 series and overclocked it to 4 GHz or more. While I'm sure the Core i7 980X is a beast, I'd be more interested in seeing how it fares when overclocked parts are taken into account, because personally I see very little reason to make the jump from the 920 to the 980 after this review. 2 more cores are nice, but not when they are slower.B3an - Thursday, March 11, 2010 - link
Anand, can you please include newer software for some benches. For instance you are still using 3DS Max 9 which was released in 2006.The latest is 3DS MaX 2010 (version 12).
I only ask because i'm sure that anyone who can afford this CPU can ceratinly afford the latest 3D rendering/modelling software. And besides that they might have better support/performance for these type of CPU's.
