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.

I would love to see a task manager screenshot during the different multi-threaded benchmarks, also games, so we can see how it utilizes the six cores and two threads per core?drewintheav - Tuesday, March 16, 2010 - link
The INTEL i7 980X has dual QPI's and will run in a dual socket mainboard!!!Such as the EVGA W555 / Classified SR-2

Where did you get that information from? On intel website it says 1 QPI. from what I know and what always was the case all i7 series are single QPI's.THats why you have Xeon series with double QPI.
Please do not post incorrect information, because people get stuck with expensive equipment not able to use it properly.

This has got to be THE most worthless, useless, expensive pice of silicon I've ever seen. An average of 13% performance increase in SOME apps AND a decrease in gaming?Give me that 1k, and I'll get myself a GTX480, an SSD, and some DDR3 modules that will give me 2x, 3x or Xx times more performance in EVERYDAY use.
Thank goodness for CUDA, Stream, OpenCL and all that cr4p.

Aenslead,I think you're missing the whole point of this cpu. It wasn't built to go fast. It was built to due serious multi-tasking. The pro A/V crowd will buy these in droves.
I can't wait to get one for my digital audio system. It will be worth every penny.

I understand your point.I do video editing myself as well as some animation, but thanks to Furry Ball (Maya) and Elemental plugins for AE and Premiere, I've come to love GPU power more than ever.
I've seen what's comming for CS5 and I do not see CPU playing an important role there.
I see very few people, like yourself, actually finding bennefit from these product launches - same goes to PII X6, although I believe this one will be FAR better priced and far more atractive.
Best,

Wondering how the i7 980X would do against a 6 core Opteron,Tech Report did some benchmark numbers when the 6 core Opterons (server) first came out,going head to head againt Xeons..interesting results when you compare the new i7. This is a rough estimate, but if AMD's 6 core is based on the 6 core Opteron this could be interesting..

I'm somewhat confused as to why, on your review, the PII X4 965 seems rather greedy, but on Toms' review of the i7-980X, AMD's offering does much better.Toms' test setups for the X58:
Gigabyte X58A-UD5 (LGA 1366) X58 Express, BIOS F4
Corsair 6GB (3 x 2GB) DDR3-1600 7-7-7-20 @ DDR3-1333
Yours:
Intel DX58SO (Intel X58)
I'm going to presume Corsair DDR3-1333 4 x 1GB (7-7-7-20)
Toms' test setup for AM3:
Asus M4A79T Deluxe (Socket AM3) 790FX/SB750, BIOS 2304
Corsair 4GB (2 x 2GB) DDR3-1600 7-7-7-20 @ DDR3-1333
Yours:
Gigabyte GA-MA790FX-UD5P (AMD 790FX)
I'm going to presume Corsair DDR3-1333 2 x 2GB (7-7-7-20)
Toms' has the PII X4 965 idling 21W lower than the 980X and 32W lower at load (using Prime95), however you have the 965 idling 10W HIGHER and using 4W more at load. Is Prime95 just favouring AMD or is there some sort of problem with your 790 rig? I will concede that the AMD rig will be using less RAM on the Toms' setup which may account for some of the difference.
One thing to note: up the resolution on a CPU-limited title such as Left4Dead and the performance gap narrows markedly. Enable AA and there's no difference at all. For graphically intensive games and/or highest settings, it won't make sense to fork out $1000 no matter how good the CPU.
It'd be nice to see how good this CPU is with multiple graphics cards... :)
