Intel Core 2 Extreme QX6800: The Fastest Desktop CPU, now with more cores

3D Rendering Performance
We've moved on to using 3dsmax 9, which allows us to run a 64-bit version of the program for our tests. The test scenario is still made up of the CPU rendering tests of the SPECapc 3dsmax benchmark. We report the rendering composite, which is simply the geometric mean of render times across seven benchmarks normalized to a set of reference scores. We ran 3dsmax 9 using its Direct3D driver given the poor state of OpenGL performance under Windows Vista.
Quad-core performance is even more pronounced in 3D rendering applications, with the QX6800 maintaining a 58% performance advantage over its dual core predecessor.
The price war continues with the 6000+ falling in between the E6600 and E6400 in performance, while the 5600+ outperforms both of its competitors.
Lightwave 3D 9.0 is available with 64-bit support, giving us another 64-bit 3D rendering test. We looked at performance under two scenes that ship with the program: Dirty_Building and Record_Player. We measured the time it took to render the scene in seconds, lower numbers are obviously better.
POV-Ray's ray tracing benchmark has been a popular CPU test for quite some time, and we turn to its 64-bit SMP beta to stress the CPUs here today:
Our final 3D benchmark is the 64-bit version of Cinebench 9.5, a fairly popular 3D rendering benchmark due to its ease of use and quick runtimes. We ran the multi-threaded CPU rendering test and reported the final score in CBmarks. Higher numbers are better:

It's one of the few games out there that benefit greatly from multi-core. It would have been interesting to see how this new CPU benefitted one of the most CPU-bound games out there right now.SilverMirage - Wednesday, April 11, 2007 - link
AT fails to be completely honest with the situation:1. AT conveniently publishes this on the exact day AMD's price cuts come into effect. That's interesting. Although AT mentions this, they could have mentioned that AMD's previous prices were not able to compete.
2. Benchmarking the 5000+ against the e6300 is inherantly biased since it will be the e6320 which is contending with the 5000+
"5000+ will have to contend with the E6300"
3. Now this depends a lot on the mobo, but I'd say that the conclusion from these benchmarks is that the E6320 and E6420 will be better for their price in a week or two.
he Athlon 64 X2 6000+ is a realistic alternative to the E6600/E6400, the 5600+ competes well with the E6400/E6300 and the 5000+ can hold its own against the E6300/E4300
(AT fails to mention again that the E6300 is an unfair comparison)

In the beginning of C2D launch we saw many reviews reducing the multiplier to see what 4mb of cache could do against 2MB of cache... it was only a few % depending on the type of apps... so stop the crap that a 6320 will outperform a 5000, same with the e6400 vs 5600. because for sure it will not!As for power consumption, yes a K8 consumes more power at load, It also consumes A LOT LESS in idle, how long is you're system idle a day? And buy a normal ATI chipset like the asus M2R32-MVP and the total power consumption at load will be less than the C2D system...
any system can be oc'ed.... one bether than the other. you are talking about 5% of users maximum. the allendale tend to oc worse these days......
nice review but start using the ATI chipsets also, they are equal performers against NVidia and cunsume a lot less and also cheap these days.

It is funny, you come here saying the Anandtech crew is full of BS, yet you do not bring any proof with you, so excuse me if I call BS on you. Things do not magically work one way, instead of another, JUST BECAUSE *you* say so.DeepThought86 - Tuesday, April 10, 2007 - link
I don't understyand why only the CPU prices are considered?? Shouldn't the overall cost including a motherboard be a much more realistic measure? What about a performance/overall (CPU+MB) cost metric be very usefulGriswold - Tuesday, April 10, 2007 - link
I just skimmed over the article, but where are the numbers for power usage?RedWolf - Tuesday, April 10, 2007 - link
One thing that is in AMD's favor is that Dell is now selling AMD machines. The college I work for is buying all AMD machines this year. Even the slowest C2D machines are a few hundred dollars more than AMD machines. All of our machines this year, including laptops, are Athlon X2 powered machines because the price was so attractive. I simply could not configure a C2D machine that came close. That price difference allowed us to go to 2 gb of ram and still be under C2D pricing for the same machine. Granted we aren't building enthusiast machines or buying for business but we are buying AMD and getting them at great prices.dm - Monday, April 9, 2007 - link
It is important to note that Intel is also coming up with a better Intel® Core™ 2 Duo E6300 and Intel® Core™ 2 Duo E6400, which are Intel® Core™ 2 Duo E6320 and Intel® Core™ 2 Duo E6420. Both have full 4MB L2 cache and will be a lot better performer. I have done quite a few tests with them here (and it includes Intel® Core™ 2 Duo E4400 as well):

You missed a wonderful processor, which is the quad core Intel® Xeon® X3210 (2.13GHz/8MB L2/1066MHz) which is an LGA775-socket compatible CPU and would appear to be binned to worked at a lower voltage. And according to guru3D (http://www.guru3d.com/newsitem.php?id=4949)">http://www.guru3d.com/newsitem.php?id=4949) the price will be hovering the $430 range. I have done some testing with this Intel® Xeon® X3210 here:
Part I (Stock Benchmark): http://fanboyreview.blogspot.com/2007/04/article-l...">http://fanboyreview.blogspot.com/2007/0...icle-lit...
Part II (Overclocked up to 63%): http://fanboyreview.blogspot.com/2007/04/article-l...">http://fanboyreview.blogspot.com/2007/0...e-little...
Anyway, overall, nice article!!!

Doing a google search, I see the price is around $750-800.. Too bad, you got me excited tooyacoub - Tuesday, April 10, 2007 - link
DM I didn't see any head-to-head comparison of 6300 to 6320 and 6400 to 6420 in your review of them. Am I reading your graphs wrong?
