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.
Well threaded applications love the Core i7's Hyper Threading; 8 threads isn't just for servers anymore.
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.
Sorenson Squeeze: FLV Creation
Another video related benchmark, we're using Sorenson Squeeze to convert regular videos into Flash videos for use on websites.
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:

Are you on crack? Lynnfield is a Nehalem without the tri-channel memory controller... Lynnfield is cheaper by $100 at the same speed bin and runs cooler. Some benchmarks on ES put the Lynnfield faster than Nehalem counterparts where the single/dual threaded apps make use of the more generous turbo mode...Put the reefer down and actually read the article. Lynnfield is 2 months away and already crushing any Phenom II or Penryn and as fast as its Nehalem counterparts at $100 cheaper.

As weird as it seems TA152H is actually an i7 platform Fanboy!philosofool - Thursday, June 4, 2009 - link
Yeah: he's on crack.nitromullet - Thursday, June 4, 2009 - link
I was asking because I want the flexibility of Crossfire and SLI on the same motherboard, which is something the Lynnfield/P55 platform will not provide. I'm worried that Intel will phase out the 920's, and I'll be left having to a $600ish cpu to get into the X58 platform.
