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

Windows 7 Application Performance
We're testing out a few new additions to our Bench database, so what we've got here are some updated application tests run under Windows 7. The CPUs compared are going to be different since we don't have as much historical data, but we'll be building it up over the coming months.
x264 HD Encoding Performance
It's what you've all been asking for - our x264 encoding test with an updated version of x264. In this case we're using TechARP's x264-HD 3.03 bench and x264 version 1342.
7-zip Benchmark & Performance
We use WinRAR for our compression test under Vista, but more and more users are switching to 7-zip. The performance is more CPU dependent so we're going to look at it. First up is the built in 7-zip benchmark:
Here we're taking the same 300MB set of images from our WinRAR test and are compressing them using 7-zip. We divide file size by completion time to get compression speed in KB/s:
The actual 7-zip archive creation process is limited to two threads, and here the 980X actually falls behind the 975 presumably because of its higher latency L3 cache. The built in 7-zip benchmark can run across all 12 threads and thus performs much better on the 980X, serving more as a bandwidth benchmark than anything else.
Sonar 8 Multi-track Audio Export
We've had some requests for digital audio workstation benchmarks so we're adding a multi-track audio export from Sonar 8. Performance is expressed in KB/s:
Again, we see a small gain here thanks to the larger cache but the extra cores aren't doing much.

THG's power numbers are often screwed up, I would not trust them.Good sites for power numbers include this, TR, Xbitlabs, and lost circuits. I have never been able to come close to any of Tom's numbers even with identical HW.

how come anand says he's excited about it and then later he says he'd never spend money on itpersonally i wouldnt spend that much on a cpu but i think this thing would be a good chip for so long that if you did it wouldnt be a bad deal even at 1000. itll probably be the close to the fastest chip for the two years

I can't figure out why the i7 870 only gets 70.6 fps in WoW while the i7 920 gets 85.5 fps. Higher clock, higher turbo, same hyper threading, integrated PCIe lanes... yet the 920 is 21% faster.Someone enlightens me please :(

That's a good question .... it shouldn't.p05esto - Thursday, March 11, 2010 - link
I'm going through withdrawl. I've had my Core i7 920 since the day they were released and really want to upgrade, like yesterday. But I'm not spending $1k on a CPU, maybe $400 could work :) if they came out with something decent and overclockable to get near the extreme version. I feel like I'm stuck at the moment....I feel the need, the need for speed!!!bludragon - Thursday, March 11, 2010 - link
Well it's a beast, no doubt about that. But the most interesting info here is that sandy bride is debuting as a mainstream part. Has this ever happened with a new cpu before? Is this just because they are going to start with less cores, or have they taken some other architectural departure?RamarC - Thursday, March 11, 2010 - link

"I wonder where Intel will price the Core i7 970, allegedly also a 6-core Gulftown derivative"Hey Anand, if history is any indication, and there's no competition from AMD, I'll bet you a dollar that the 970 will retail for around $850 - the same price of the venerable mainstream Q6600 that was released a few months after the $999 QX6700... ;)

i heard it was gonna be near the 600 mark.It wont be cheaper then the 960, and it wont be more expensive then a 980X.

You start by saying, "I have to say that Intel's Core i7 980X is the first Extreme Edition CPU that I've ever gotten excited about. ... The 980X gives you its best regardless of what you throw at it. ... If money were no object, the Core i7 980X is clearly the best you can get."But then you conclude with a much more somber, "The Core i7 980X is such a difficult processor to recommend."
What really threw me for a loop, though, was this comment: "You could pick up a dual-socket Xeon board and a pair of quad-core Nehalem Xeons for a bit more than a X58 + 980X"
There are so many problems with that statement :( It's very un-anand-like.
Foregoing any assumptions about what you mean specifically, I haven't seen any 3.0+ GHz XEONs sub $1,000. Even then, I'm not convinced a dual-quad would even outperform the 980 unless you went with a couple of EPs, and that's way off the price mark. Your conclusion ends with a mild suggestion towards a platform you didn't benchmark. The 980 can put you at 3.6 GHz in a single-threaded app which you can't get from a dual-XEON.
The 980 truly is the best of both worlds, as you initially indicated.
Given that that the 960 is 3.2 GHz @ 4 cores is running ~$600, you can snag a whole 2 more cores, a speed boost, AND other 980-only perks for an extra $400. Think back to what the EE got you at its debut - another 10%-20% clock and an unlocked multiplier for something like a 100% markup over the next highest model.
This chip really seems like a bargain, but that's my opinion. I'm considering the 980X over a new 930 build just for the longevity it provides. It's just SO much power for the money. The simple fact that it puts it in the same league as a dual-quad XEON raises the hair on the back of my neck :)
Can you elaborate on a XEON system that would be comparable in performance and price to the 980? Maybe that would be a good article. I wonder what kind of performance hit you take with the QPI between two chips versus what you get with the 980. Skilltrail did okay, but the FB-DIMMs really hurt gaming. I think a 980 v. XEON would be a great article.
