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

DivX 8.5.3 with Xmpeg 5.0.3
Our DivX test is the same DivX / XMpeg 5.03 test we've run for the past few years now, the 1080p source file is encoded using the unconstrained DivX profile, quality/performance is set balanced at 5 and enhanced multithreading is enabled:
Our DivX and WME tests are getting long in the tooth. Most serious encoding is done using H.264 now, but I included these results to show that even in lighter workloads the 980X can still manage to pull ahead of the 975. The 980X is 30% faster in our DivX encode test, and it completes the encode in less than a quarter of the time of the old Pentium EE 955.
x264 HD Video Encoding Performance
Graysky's x264 HD test uses the publicly available x264 codec (open source alternative to H.264) to encode a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
To see what 6 cores and 12 threads can do we needn't look any further than the second (encoding) pass of our x264 benchmark:
The Core i7 980X is nearly 50% faster than the Core i7 975, 76% faster than the i7 870 and over twice the speed of the QX9770. This is a greater performance jump than we've seen from any single architectural shift. If you are serious about video encoding, you want Gulftown.
Windows Media Encoder 9 x64 Advanced Profile
In order to be codec agnostic we've got a Windows Media Encoder benchmark looking at the same sort of thing we've been doing in the DivX and x264 tests, but using WME instead.
Our Windows Media Encoder 9 test is the lightest of our video encoding tests. Without stressing the additional cores, the 980X performs no different from the 975.

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... :)
