PAR2 Multithreaded Archive Recovery Performance
Par2 is an application used for reconstructing downloaded archives. It can generate parity data from a given archive and later use it to recover the archive
Chuchusoft took the source code of par2cmdline 0.4 and parallelized it using Intel’s Threading Building Blocks 2.1. The result is a version of par2cmdline that can spawn multiple threads to repair par2 archives. For this test we took a 708MB archive, corrupted nearly 60MB of it, and used the multithreaded par2cmdline to recover it. The scores reported are the repair and recover time in seconds.
The multithreaded nature of this benchmark favors the Core i7 systems since they can work on more threads at the same time.
The Q9550S continues to hold the average power advantage.
And it's the lowest power quad-core here when we look at peak power consumption as well.
While the Q9550S is the most energy efficient of the quad-core Penryn based processors, the Core i7-920 is still more desirable from a performance per watt standpoint.

why was a normal 95W TDP Q9550 not included???Anand Lal Shimpi - Wednesday, January 28, 2009 - link
I didn't actually have a 95W Q9550 available (Gary has the one we used in our Phenom II review). I provided the Q9650 and the Q9450 so you can get an idea of where the Q9550 would fall.Take care,

I've got to agree with UltraWide.The news is Intel just came up with the S-line of procs.
But the test doesnt compare any S to non-S CPUs...
Isnt that what really matters? the perfomance and power consumption difference between the 95W and the new 65W is what I want to see.

finally nice to see the pick and choose Anandtech bench, need to take it out of beta, save me a trip to tomshardware.Calin - Wednesday, January 28, 2009 - link
Those processors are perfect as replacements in servers already validated for the 95W version of the same processor. While buying i7 would be better, maybe the i7 servers weren't validated (remember the 3 years of support for business-related hardware lines)danchen - Wednesday, January 28, 2009 - link
looking at the numbers, it doesn't look like its worth the extra money.Its like buying an "environmentally friendly" car - high initial investment, takes many years to get an ROI.
perhaps if you're the type who runs your computers 24/7, it may actually save you some bills in the long run.

Or... you could just undervolt your current CPU. Voilà.BTW, what is the default Vcore of these processors?

Depends on the model, but I assume you mean the likes of the Q9550. Those are 1.22V.http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">http://www.anandtech.com/cpuchipsets/showdoc.aspx?... shows a few.

"the publicly available x264 codec (open source alternative to H.264)"firstly x264 is only an encoder, and doesn't have an encoder included. x264 is an Open Source implementation of the H.264 standard. it's not an alternative to it.

sorry for the mistake, I meant to say it doesn't have a decoder included ;)
