    Actually, XWMC is a funny thing. With as fast of a CPU as you've got, I fully expect XVMC is using up more CPU time than software decoding would (assuming non-highdef material).

    I did test it, and there is a small difference. Not big, but there. But you're probably right in that I could happily leave it all to the CPU and not notice anything. Might even save memory bandwidth come to think of it (onboard GFX). And yeah, aside from the odd demo I've tried very little HD content.

    The quality has nothing to do with XVMC

    Aye, I'm aware of that - I was just pointing out that XVMC is the sole use I have for GFX hardware (short of pumping the image out of the cable, anyway) whereas the tone of the article seems to suggest that using ATI/nVidia proprietary libs is the only way to go if you want "acceptable" quality output, when in fact everyone would get by just as well with onboard GFX and libavcodec. It seems to be whatever the hardware.info equivalent of a slashvertisement is called ;)

    Why no reviews of any of the many myriad MPEG2 decoders out there? It's like they're saying that the only way you can get super high quality DVD playback is to use a modern GFX card and a specialist decoder library.

    My MythTV system uses Xine to play DVD's via an nVidia 6150 chipset straight into the DVI input on my TV. It uses XVMC motion compensation to cut down on CPU usage (not that MPEG2 decoding and filtering uses much CPU at all these days - my AMD64 3500 sits at 1GHz and uses about 15-25% CPU playing back a DVD with postprocessing activated), and the quality blows anything else I've seen out of the water. Similarly, using ffdshow on my workstation in windows mode results in a really good picture.

    If you ask me, most people will be more than happy with the default decoder that came with PowerDVD or what have you. It seems silly to do a "PC's vs. DVD players" comparison and leave out what 80& of people are using. Are there any other MPEG2 decoder reviews around?

    I'm in total agreement with you on this. My desktop has 256MB swap and 1GB of RAM. The only time Linux has ever touched swap was when I was importing 8GB of Eudora psuedo-MBOX files into KMail (I forget the exact command I was using). At the time I had 2GB of swap (rule of thumb, right?), and the import process swallowed it all up. I didn't notice in time and the system became completely unresponsive; not even a Ctrl-Alt-Backspace worked. I couldn't ssh into the machine either. Eventually the process died, but it took a good 30 minutes.

    My MythTV backend with 2GB of RAM touches maybe 5-10MB of it's 2GB swap at the worst of times, even with quite a few memory hungry apps (Opera, amarok, myth transcodes) running as long as the system is up and pre-emptive swapping turned on.

    When a process goes nuts, I want it to be killed ASAP. Leaving it to fill up xGB of swap and bring the server to its knees for x minutes is silly. I admit that in machines with less RAM than mine swap is a great idea, but on modern machines the overhead for using virtual RAM seems much higher, and I get no obvious performance increase from it, even with 10k RPM drives. Since the 4GB barrier isn't a problem any more for server at work (64bit Debian, yay!), we just plumped for gobs of RAM instead of new servers every x years (since we don't do much that's CPU limited). Heck, I even have MySQL DB's mounted in tmpfs at home.

Last I heard, Debian were quite content for others to use this as a baseline to extend Debian into the user-friendly market, hence distros like Ubuntu.

    Like I keep saying over and over again - there's a place for Debian, just like there's a place for Ubuntu. A corporate server farm doesn't need a GUI installer - they have one of their code-fu's do a single install and then roll out an image to 300 empty boxes via BOOTP. Someone rolling out Debian on the desktop at a company would do much the same thing.

ANd now we're seeing that most of the big advances (new "enterprise" sockets, K8L stuff) are going to benefit the servers before they benefit Joe Public.

    AMD knows that, whatever market share it has in the desktop arena, Linux is a major player in the HPC and 2P+ spaces and knows that Linux sysadmins won't tolerate buggy chipsets or flaky binary drivers that may end up being unsupported under kernel 2.8 or whatever. Hopefully AMD has the nouse to do an Intel and make their chipsets open spec across the board a la Intel, enabling excellent support under Linux and any other OS that happens to come along. I know for a fact that sometimes shoddy chipset support under Linux has been a turnoff for me in the past and I've lusted after some of Intel's chipsets on my own A64 systems.

  20. Re:Not that far fetched. on ATI and AMD Seek Approval for Merger? · · Score: 1

    True dat. I've always loved AMD's own line of chipsets - IME they're never the fastest out of the bunch, but they're always rock-solid stable and (naturally) are open spec and so work perfectly in Linux, often before release. Much like Intel and their chipsets in fact.

    Contrast with ATI and nVidia chipsets (now that VIA, SiS and ULi are pretty much out of the market) - drivers are always binary blobs. True,you can generally run Linux on an nVidia chipset with open source drivers, even up to the reverse engineered ethernet controller, and suffer a negligible performance decrease over the nVidia code. But every account I've read of people trying to use recent ATI chipsets under Linux have been fraught with tales of lockups, appalling transfers speeds, hardware not functioning, clocks running way too fast, you name it. ATI's answer is "just re-install our driver after every kernel upgrade". Great.

    I don't doubt that AMD are capable of running their own chipset division, but they're a much smaller company than Intel especially in terms of fab capacity and until recently were only just keeping up with demand. But will they even entertain the possibility of "enterprise" chipsets any more if they're taken over by our closed source overlords?

    And before you bemoan me for bringing up the Linux argument "no-one uses Linux! AMD doesn't care! Open drivers can rot for all they care!" - I'll tell you now that they damn well do care. Opteron and servers are their fastest growing markets, and will most likely continue to be so long as theirs is the only x86 arch that scales to 4, 8 or more CPU's efficiently. Linux and other OSS OS' are a *very* big slice of this market. Maybe we'll be lucky and ATI will allow them to produce an open spec "enterprise" chipset with the exact same functionality as ATI's new UberGamer 733T-XL, only at twice the price of the closed spec part. Yippee.

    Call me paranoid, but IMHO this merger (if it is indeed anything more than conjecture) could spell very bad things for AMD and I'm convinced we need AMD to stop Intel pulling another Netburst on us.

    Of course, there's always th eossibility of ATI doing cool things like making a skt940 chip that acts as a dedicated H264 encoder or some such stuff, but since the specs are all open they could do that without taking over the company.

    To sum up: is there any point to this merger from the customers perspective? Not that I can see. IMHO we don't have enough players in the CPU and GPU market as it is.
