File Compression/Decompression 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.

PAR2 Multithreaded Decompression Test

Here both the K-series SKUs are faster than the 980X. The Core i3 2100 manages a 13% lead over the Core i3 540.

In all of our compression tests, Sandy Bridge does very well. The 2600K is faster than the 980X in the real world compression tests, while the 7-Zip algorithm benchmark is fully threaded and shows you what would be possible with 6-cores.

    "perhaps we should return to just labeling these things with their clock speeds and core counts? After all, it’s what Apple does—and that’s a company that still refuses to put more than one button on its mice. Maybe it’s worth a try."

    I hate to sound like the resident Mac fanboy (I'm platform agnostic) but I want to point out:

    1. Apple sells by trim and display, they don't really make a big deal of the CPU (probably because they stick to low-end and midrange CPUs)

    2. They have been shipping multi-button mice for nearly six years now. Come on!

    - gtx460 image quality definitely the worst
    - 6870 image quality next
    - quicksync/snb image quality are the best (marginally better than 6870); I did notice some color loss in the flowers behind the umbrella when I zoomed in on the quicksync picture, so I'd have to give SNB the title in terms of quality. QuickSync gets the title in terms of performance.

    My last Intel cpu was a prescott 2.4ghz P4 OC'd to over 3ghz... back in 2004? My last 3 main system builds all AMD.... I was thinking about going to an X6 in the near future, now I guess maybe not. My price point is pretty much $200 for the cpu + motherboard so maybe I'll have to wait a couple months.

    Suddenly my 2 year old Phenom II seems very, very slow...

    I just received my 2600K. It only had the normal fan. No special heatsink/fan for the 2600K. The same heatsink as the rest....

    This is a fraud since I placed my decision to take 2600K instead of the 2500K based on the better heatsink and the cache.

    Same here.. Very disapointed as I would have purchased a better heatsink if I knew. I guess I'll just do the install with the standard crap HS and hold off on over-clocking until I get a better one.

    Many of us are using older equipment. And, for those of us with limited funds it would have been nice if you would have added the Intel Q9650 and run all game benchmarks at 3.4GHz [ the speed of the 2600K], except for the default 3.6GHz speed of the X4 975BE, leave it there.

    I have a QX9650 that I purchased from eBay and it does 4GHz+ with ease, in a Gigabyte P35-DS3R motherboard, even with my ancient cooler [Thermalright XP-90] that I pulled from a socket 478 motherboard [$5 adapter].

    Note: I lapped the XP-90 with a slight convex shape to better use with un-lapped CPUs.

    In any event, a "quick and dirty" or simple overclock would have yielded at least some usable information. To save time, no need to try to get the maximum speed from all components.

    As long as the CPUs were already overclocked, you could run all benchmarks at those speeds, not just games. Many of us overclock to get more for our money.

    You included the ancient Q6600 at it's slow default speed - in some of the benchmarks. Why didn't you include it in all benchmarks?

    Your normal benchmark page does not include a full, or nearly full, list of games and CPUs, so, comparisons are difficult to find, example here anandtech.com/bench/CPU/62

    Where does this leave those of us with older equipment that is still chugging along?

    DRM inside the cpu? People is blind?. The sad thing, everybody is going to buy this.

    I just bought a upgrade "kit" from an core 2 2.8 quad to i7 950 :(
    but I got 6 sata ports I noticed the new boards have 4+2
    will the more advanced boards have more ?

    I didn't see it discussed. Did I miss it?
