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.

W3680 will be a workstation hexcore @ 3.2ghzIm guessing since its a 3600 series, it will be a 1 x QPI, so it will not work in tandium on a DP board.
Xeons are uber expensive tho.
And this one if its gonna be priced like the W3580's is gonna have a price of around 1499.
:X

I know the OC's were on stock cooling but being this chip starts out @ 3.33 ghz and having a smaller 32nm size, the OC capability seems very underwhelming. I heard this chip is good for extreme overclockers because they did away with the cold boot bug. This thing probably puts out to much heat for any current air or wc setup to get a good oc out. That being said i dont see replacing my D0 920 anytime soon.aigomorla - Thursday, March 11, 2010 - link
come to our cpu and overclocking forum.http://forums.anandtech.com/showthread.php?t=20576...">http://forums.anandtech.com/showthread.php?t=20576...
Or read one of my comments with a forum link.
I showed people what it can do on higher voltages, when you take heat away from the equation of being the limited value.

With the 800 dollar premium over an I7 920, why don't you just build a second 920 system instead!aigomorla - Thursday, March 11, 2010 - link

I welcome you guys to join our forums.
You'll see more info on stuff on the OC potentials in that preview.

Looks like the i7-860 is where gamers and people who run lots of multicore apps want to spend their money. Gamers will save $750 and will see almost no difference in performance.RaistlinZ - Thursday, March 11, 2010 - link
Yes, gamers will still be more than satisfied with their i7 920's @ 4Ghz. Especially considering those chips are only $200 at Microcenter these days.I just hope the upcoming Xeon CPU's will have more of a mainstream price.

I think the L4D performance is actually due to the extra cores, as source engine games have n-1 multithreaded scaling. It's been shown to have diminishing returns past 3-4 cores, so a 6% bump for an extra 2 cores makes more sense to me than the extra cache, considering no other games show this level of performance increasevailr - Thursday, March 11, 2010 - link
What happens if you put this 6 core CPU in a non-upgraded bios X58 board? Do you then have the minimal functionality to be able to flash the bios to the updated version? Or does the system fail completely, to even show anything on the video display?Just wondering...

If your bios can not handle gulftown, it will just refuse to post.eVGA boards are even more picky. If you somehow manage to get a hold of an A0 stepping gulftown, you can not use the same bios on a B0 or B1 gulftown.
The b0 and b1 are the retail versions, while the A series were pure evaluation / testing samples.
Some asus boards should support gulftown without bios updates, however its still recommended u get one.
And if u guys come into our forums, you will see i pushed one up to 4.4ghz with HT ON, @ 1.388 vcore, so i think my 980X is better then the one Raja has.
Sorry Raja.. :P
