      Actually just one component of the northbridge, the memory controller, was moved into the CPU. Other things such as: AGP interface, interface to southbridge, etc (hmmm is there anything else?) still need to be on a separate chip.

      So add a fan on yourself if you want to OC.

      Most people don't want to OC. I've done it before and I won't do it again - the added speed isn't worth the instability. Especially if you're planning to keep using the computer for several years.

      As others have said, adding yet another fan is a detriment for normal use. It's another mechanical part that will fail - especially since most of the bundled fans are as cheap as they can afford to keep prices down.

      One of my buying criteria on a motherboard is passive cooling for the north bridge. I don't need the active cooling and I really don't need the added noise.

    My co-worker was telling me about this earlier this morning. I especially like the vacuum tubes for the audio on the motherboard. Audiophiles will be drooling over that. Do they make mobos now with that on them?

    On a side note, I like the number of pins on the cpu socket. Hammer is gonna be interesting to say the least.

      This might be ok for gaming, but having worked for a music software company in the past, we'd ALWAYS tell customers to stay away from mobos with onboard audio. Latency is usually very high which comes into play when recording and playing multiple tracks with live effects.

      I find it very interesting that they would put tubes on there for the center, satellite and stereo channels. From my experience rec.audio.* groups (sampling of the "high end" users that have computers), those that prefer the tube sound would probably not buy a mobo with that (preferring instead to waste $20k on an amp that would do it for them).

      Tube power amps sound just a little bit better than their solid-state counterparts. The place where tubes really shine is in Class A (non-push-pull) amplification, which is generally used in the preamp phase. It's here where tubes' famous even-order harmonics are produced -- it's these octave harmonics which make tube sound so sweet and agreeable to human ears. Taking audio from a regular computer sound card, audio which has been produced with a solid-state preamp, and pumping it through a $20k tube power amp is just what you called -- a waste. However, when tubes are intimately involved in the sound production within the computer and are used for preamplification, you can hook it up to a $150 solid-state power amp and it will sound better than sound from a regular soundcard.

      If we are talking about the same thing, I believe they have stated they are DE-EMPHASIZING the Clawhammer ... in other words, its still on track for release in the first half of 2003 (still way off compared to their roadmap, of course) with Opteron in the 2H03.

      Right now AMD is working towards profitability, meaning going after markets which are stronger (which are, right now, the value microprocessor market) thus the de-emphasizing of the latest and greatest.

  11. Why vacuum tubes? by f97tosc · · Score: 5, Interesting

    Certainly the true audiophiles often use tubes for their systems, but this does not mean that these are superior for all situations.

    What kind of sound will go through the system? A normal transistor has a 'snappier' sound to it, which is better for a lot of modern music, and I would imagine for sound effects in computer games.

    I guess if you want the best for your classical LPs then maybe this is something for you, er, no, then you would be better of to get a real amplifier.

    For those of us who like having a motherboard we can place into a system and not have to worry about parts failing on it, the wonderfully solid-state nature of passive cooling is impossible to beat. If I want more performance, I'll either pay more or wait a little while longer, thanks. I want stability and a minimization of moving parts in my PC, because moving parts = failing parts. Failing parts are expensive!

    How many active-cooling north bridge motherboards have you owned? I owned one. Its north bridge fan failed after only 3 months of constant use. Compared to every other motherboard I own, none of which require a fan (most don't even require a heatsink, and they power 1Ghz systems!), it was a terrible mistake purchase. I've since replaced it with a motherboard bought specifically because its north brigde used passive cooling. It's given no problems in the year+ of service it's given.

  15. Re:What are Vacuum tubes? by f97tosc · · Score: 5, Informative

    Out of plain curiousity (and probably because of inexperience) I'm curious on what exactly vacuum tubes are in relationship to sound, what advantages/disadvantages they offer and anything else interesting to know

    Vacuum tubes were used before the invention of transistors. They serve basically the same function, but are much bigger, draw more power and are slower in their response. For these reasons, they are hardly used any more.

    However, when they are used to amplify sounds, they give a somewhat different sound than do transistors. Many audiophiles argue that the vacuum tube sound is superior.

    However, and now comes my personal opinion, recently something of a hype has started around tubes. People who don't really know much about sound systems take tubes as a guarantee for getting superior performance. They fail to realize that the sounds are just different and which one is superior is largely a matter of personal taste - and what type of sound is being amplified. I am not at all convinced that tubes are better for sound effects in games, for example (as they have a slower response).

    I was under the impression that they were for the audiophiles who want better sound. That sort doesn't use the onboard sound, no matter how good it may be. It's pointless to use them on a motherboard. If someone really cares enough about sound quality to use vacuum tubes, they'll have their own sound card to use.

    Besides, they just look ugly. 3 big balls of glass sitting on your motherboard. And then when one blows, you'll have to replace it.

  18. Re:What are Vacuum tubes? by Animats · · Score: 5, Interesting
    The whole tube audio thing is a joke. First, the whole business of tube audio revolves around how clipping distortion occurs at saturation. If you're getting any measureable distortion from a low-power amplifier that follows a D/A, your circuit design is all wrong.

    Second, if you want some specific transfer function under overload, you can get it by design. There's a famous story about this. Some years back, Bob Carver, the well-known amplifier designer, took a tube amplifier that was well-regarded by the "high-end" audio nuts, and characterized its response with the usual test gear. He then designed a transistor amp with the same transfer function. In listening tests, listeners couldn't tell the difference.

    But his transistor amp didn't sell. He then, as a joke, designed the Carver Silver 7, the most overdesigned tube amp of all time. Three chassis per channel, chrome-plated everything, insane price of about $25,000. It got great reviews. "Amp of the Decade" from The Absolute Sound.

    "to have active cooling on the north bridge, too many new, high speed bus mobos are coming out right now with passive cooling that doesn't come close to making it easy to OC"

    The chipset "Northbridge" does not get over clocked with the CPU using hyper transport. The memory controller is on the cpu. So you can increase the speed of the CPU and memory without affecting the chipset "Northbridge" at all. I used quotes around Northbridge because all the features that most people think of as being part of the Northbridge are in fact incorporated into the CPU.

    "What, still only 32-bit PCI slots? :::yawn:::"

    This motherboard contains a hyper transport to 32 bit PCI chip. Hyper transport runs at 6.4GB/s. PCI 32 is 133 MB/s. The manufacturer chose to use 32 bit PCI because this is a commodity board. Theoretically, a motherboard could include 6 PCI-X busses supporting 6 cards each before saturating the hyper transport bus.
