    Without registers, CPUs won't be there. Not so with cache. Cache it just to speedup the fetching of data and instructions to be processed by the CPU using the locality of reference factor. CPU has no clue as to the existence or the size of the cache.

    Anyways...registers are not important in this case, because every CPU has registers that is enough to do what it is supposed to do (except certain RISC architecture CPUs which can create register stacks instead of memory stacks for instruction stacking)

    I would like to compare 7-zip performance with a Conroe CPU running at my specs. Mine is a Conroe-2M.

    I'm quite mixing up my basics. :(
    I was just trying to make an example for that cache is important argument.

    I agree that there will be no CPU without it's set of registers. Different processor architectures have different instruction sets. This might be useful in designing compression algorithms. I've heard that the architecture is closely observed in creating encryption algorithms and for creating encryption crackers (decryption).
    I'll very much like to do some compression tests on architectures like Sun SPARC, I also don't have much experience with AMD processors.

    The laptop I did the tests was a Core 2 Duo T5600 processor. (1.83GHz 667MHz FSB 2MB L2 cache)

    My tests were conducted on a 2.8GHz Core 2 Duo with 1600MHz FSB (overclocked as you can see :D) and 2MB L2 :(

    We will have the power of 1 teraflop within 3 years I think. The 80-core Intel behemoth :love: :love: What's amazing is how it uses less power than a contemporary Core 2 Duo at full load. This is 80 * 3.2GHz !!! :shocked:

    Yes that's super power at todays standards. Who knows what we are going to need in a few years. :)
    I'd like to see that with this:

    You girls always think wrong……………..(kawada hadeida manda)

    Some times it’s more important compression than time. (It’s true to me)
    Eg: Data backup process. Creating game collection CD, etc…

    When we need extreme compression, which will help us?

    Still didn’t get it……if…….forget it.

    If you have an old machine, It will take too much time to compress with programs like KGB UHA or WinRK. As I told earlier these programs are optimized for extreme compression ratios, not normal home use. Normal home use means things like packing some files to send through email (you can use even tar format). Windows does its own compression in NTFS drives to save disk space. Normal compression programs are optimized for the convenience of general use by the busy individual who can't wait hours until his pack of files are compressed or extracted. And also to give a fair compression ratio.

    You would be comfortable with programs like 7zip and winrar in general use. Don't try the high compression archivers unless you have a machine with high processing power and you are ready to spend some time. (patience will be very much appreciated :P)

    Don't hope programs like UHA to be user friendly, but WinRK might be a good choice for you to backup your games and music. :)

    There are only a few in this world who needs extreme compressions, scientists and researchers in labs (can be IT or non IT), businesses which are highly sensitive to data and which needs to manage a very large archive, government sector (law, police etc) and last. . . . . . . . . . . . .pirates! :lol:

    Do you belong to any of the above to need extreme data compressions. I also do backups of my data, but I'll not try to compress them with archivers, suppose you want a single file from a very large archive you have burned to a CD, (winzip seems ok, but rar will take too much time to extract the file), Also you may want to use your data on another OS like Linux, You will be in deep trouble since rar is not supported in Linux. In case of a CD of music tracks, you could have played it in a CD/DVD player if it's not archived.

    Remember, data must be backuped, but the golden rule is that the backup data must be easily retrievable anywhere anytime. So IMHO it's convenient to have your backup CDs/DVDs in raw format than archives. :yes:


    UHA is very popular among pirates who create game collections :P

    64bit for Core2 and 32bit for P3 and P4

    7zip gives you the choice for a 64bit/32bit version, winrar and winzip doesn't.
    hapoi...!~ nothing to say but motta *******

    oyage experiment ekata gaththu versions eka mokakda?

    that will give answer to your > :confused:
