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:

"Microcenter, for in-store purchase. I purchased an i7 860 last week for $229. The i5 750 is cheaper, $159 seems right."Yeah with 8.5 % tax that price is $250 + how much for gas?

For online purchases, you may still have to factor in sales tax and shipping. There's also the cost of having to wait.Between your current computer and the upgrade, what is the performance gap? For that gap, how much time could have been saved in your work? Because you saved time at work, how much $$ was saved?
Things can become complicated or we can just stick with the retail pricing at these stores and leave out the other factors.

The I7 860 is $290 at newegg with free shiping and no fees of any kind.In microcenter you have $230 + $20 tax + gas .The point is the differance is less than $40 with microcenter .You should always compare final price for the purpose of being fair. How long have you been waiting for I7 860 cpu to come out ? How much have you lost for that time ?So if you have been waiting 8 months how is 3 days going to be bad?If that is so bad how come you din't get 920 before?BlueBlazer - Saturday, September 19, 2009 - link
I think he's referring to this?http://www.microcenter.com/single_product_results....">http://www.microcenter.com/single_product_results....
Core i5 750 = $159.99

As well as this...http://www.microcenter.com/single_product_results....">http://www.microcenter.com/single_product_results....
Core i7 860 = $229.99
My +/- 1 cents..

This doesn't even factor in the savings on Watts used.jordanclock - Saturday, September 19, 2009 - link
But how many LOCs per fortnight can they process? Could you please provide your metrics in more understandable formats. At the very least I would like to see how many TuxRacer compiles per hogshead of cider (the good stuff, not the end-of-season stuff) we can expect.BlueBlazer - Saturday, September 19, 2009 - link
Skewing the numbers? Try..Intel E5300
142 / 69.99 = 2.02 SYSmarks per $

Where in the review is the PII X4 620?
