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.
Our Par2 test actually puts both the 860 and 870 slightly ahead of the Core i7 975. It's clear that anything faster than a Core i5 750 in this case basically performs about the same. It looks like we're starting to be bottlenecked by our SSD.
Microsoft Excel 2007
Excel can be a very powerful mathematical tool. In this benchmark we're running a Monte Carlo simulation on a very large spreadsheet of stock pricing data.
Sony Vegas Pro 8: Blu-ray Disc Creation
Although technically a test simulating the creation of a Blu-ray disc, the majority of the time in our Sony Vegas Pro benchmark is spend encoding the 25Mbps MPEG-2 video stream and not actually creating the Blu-ray disc itself.
Again the Core i7 860 pulls slightly ahead of the 920 and falls short of the 870, right where we'd expect it to land.
Sorenson Squeeze: FLV Creation
Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.
The 860 and the 920 keep trading positions, but as you'd expect given the similar price points - the two perform about the same.
WinRAR - Archive Creation
Our WinRAR test simply takes 300MB of files and compresses them into a single RAR archive using the application's default settings. We're not doing anything exotic here, just looking at the impact of CPU performance on creating an archive:

Your prices are wrong. The 860 is $230, which makes it 0.97 SYSmarks per $.The 750 is $160, which means 1.36 SYSmarks per $ by your measurement.

I just love it when someone quotes some below cost, loss-leader sale price they heard about somewhere once to prove a value arguement.yacoub - Saturday, September 19, 2009 - link
You mean "on-going, still valid sale prices that you can get today".stanljl - Wednesday, September 23, 2009 - link
Most of the US doesn't live reasonable close to the 21 cities that have microcenters. In cause you haven't looked there really aren't that many locations so "on-going, still valid sale prices you can get today", really doesn't apply to the vast majority of the people in the country.strikeback03 - Monday, September 21, 2009 - link
It is a valid price, but please add the disclaimer "If you have a microcenter nearby" instead of just pretending those are widely available prices. I plan on buying a processor when I help my parents move down near Philly next month, otherwise I (like most) don't have a Microcenter anywhere nearby.formulav8 - Saturday, September 19, 2009 - link
Yeah with only 2% of the people able to get one at near that price. Quoting an obvious loss leader as valid pricing for those looking it nutty. Newegg or ZZF is a much better gauge of price.NA1NSXR - Saturday, September 19, 2009 - link
Who cares, let him pay up. Nothing on P55 has made me regret getting that $200 D0 920. Nothing. Not even close. The OC, heat, and platform pricing advantages all failed to materialize.The 920 is not a 2.66Mhz bloomfield. It is a 3.8GHz chip supporting the fullest featured consumer platform at the moment.

Where? Where? Where? From a reputable supplier and with in-stock delivery, of course.Newegg and ZipZoomFly: 860 $299
850 $199

Microcenter, for in-store purchase. I purchased an i7 860 last week for $229. The i5 750 is cheaper, $159 seems right.
