The Sandy Bridge Preview

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.
Clock for clock there's very little advantage compared to Lynnfield, but compared to the i7 760 the Sandy Bridge advantage is no less than 35%.
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:
Without Hyper Threading, the Core i5 2400 equals the performance of the Core i7 880. Turn HT on, and this Sandy Bridge part that may end up costing ~$200 is nearly as fast as the $999 Core i7 980X.

Because the 980X is a 6 core and the 950 is a 4 core!It doesn't make sense to compare a 6 core to a 4 core when there's an $800 price difference.
A 1366 4 core (preferably at the same CPU speed) would make much more sense to see the differences in various architectures/sockets.

ok and the diff in performance would be what now? if they are showing you the diff and how well the new 2 gen cpu's are to even a $1000 cpu what makes you think that the Core i7 950 which is slower in performance then a 980X would fair? I mean it's common logic that if the 2nd gens can run almost on par in many bench test with a 980X then obv it's going to run better then the Core i7 950's.kake - Sunday, August 29, 2010 - link
Damn you Intel! Damn you to hell!!I have been living with an AMD Athlon XP 1800+ since 2003ish. This was mostly because I liked the Soundstorm that did a very good Dolby Digital Live output. For the last eight months I've been having to run it at about 2/3rds speed because all the caps on the motherboard burst, and it ran at 80C all the time. The GPU fan died and I wired a 80mm fan on top of it, but it had overheated once too often to do any 3D work. The DVD burner wouldn't read or write, the DVD reader wouldn't open except under duress. The SATA bus started to scramble any data read or written through it, the second LAN port (the good one) died, and the USB would usually demand a musical chairs routine with the mouse and keyboard to get them to work.
So last week I bought all the bits and built a very reasonably priced (370 with shipping and tax) i3-530 based HTPC. I've never seen anything so gorgeous as the first time I played Avatar in 1080p on the plasma.
And now you tell me all this?
Damn you Intel, I'm sick of progress.

There is a technological reason to bury 2 sockets that are still alive? they are screaming performance yet! i dont get what intel wants with this behavior, ¿Hate from the IT sector? i love the performance, but it is designed in a so closed and trickery way, and completely dropping two nice and stablished platforms, this thing wants to be hated. I hope amd destroys this crazy ideas of intel with llano oem sales, even being inferior in cpu performance.Googer - Monday, August 30, 2010 - link
What exactly does a Lifestyle processor do?mino - Monday, August 30, 2010 - link
Probably cuts your hair while playing Crisis :)Googer - Monday, August 30, 2010 - link

I understand what the difference between unlocked, regular, and power saving CPUs are. But what exactly does Intel mean by a Lifestyle processor? How is it different from the others? What exactly is a "Lifestyle CPU"?zepi - Monday, August 30, 2010 - link
What does the mystical "load power" mean? Does it mean running Prime95, Furmark, both or even something "real world" like Starcraft 2?
