        As the parent pointed out, AGP cards may come down in price. So if you just bought the latest Radeon 9800 at $500, you'll have to watch helplessly as others buy it at $50 bargain bin prices a couple years from now.

        To be fair, I disagree with the assessment. If AGP cards become rare, while people hold on to their AGP-supporting motherboards (especially those running Athlon64's), their value is going to rise. At least, it'll rise up to just before the point where it's cheaper for people to get a new mb (and RAM, and CPU) along with their video card.

          This is true anyway. This year's top of the line card will be the low-end "bargain card" in two or three years. Anytime you buy the top-of-the-line anything you have to be aware of that. The only difference in this is that you will need a new motherboard for the new cards. But since these cards aren't available yet, what's the big deal?

            Absolutely. Video cards are like sand in the wind. I'm not a gamer myself, so I get to be amused as my friends pay $500 for a card, then sell it on eBay 12 months later for $200 and buy another $500 card.

            I recently pulled a graphics card out of the trash box at work and we putting it into a test box. A friend laughed and said that he had paid several hundred bucks for that "top end" video card about 4 or 5 years ago, and now it wasn't even worth keeping out of the dumpster; any $30 cheapo would whip it these days.

            I also don't see how this hurts buyers of the latest AGP cards. It's not like you won't buy a new card when you build a new machine, anyway; by the time you build a new machine that $500 card will be a lamer POS anyway.

        ...but in case your multi-GHz processor will serve your needs just fine for several years, while your AGP card won't last you nearly as long, you'd wish you had an upgrade path, yes?

        That being said, not being an FPS freak I've found that by the time I'd like to replace the GFX card, there's also lots of other new things on the mobo, new CPU socket, new memory interface/speeds, RAID / SATA / GB LAN / dual LAN / Firewire / USB2 / Bluetooth / WiFi / PCI-X / whatever to justify upgrading the whole machine.

        Or, more to the trend, perhaps what you'd really like is to change form factor from ATX to a mirco-ATX or similar, get one of those mini-PCs.

        But, if what you do is gaming, judging by the hours some people I know spend, getting the latest GFX card every six months be "reasonable". Just compare it to how much money other people dump into hobbies like cars or skiing or whatever. If you do it all the time, you want some seriously good equipment even though you'll never "recover" the investment.

        And for those, it kinda sucks since they'll need a new computer to go with their spanking new GFX card. On the other hand, the AGP slot has been around for a long long time now, going from 1x->2x->4x->8x. Compared to pretty much every other interface, it's hardly surprising that it's time for some design changes.

      In a nutshell:

      PCI, AGP, and ISA are all parallel systems - you have a wire for each data bit.

      PCI express uses a VERY high-speed serial bus to carry the data. How high speed? One serial channel will carry more data than a standard 64 bit 66MHz PCI bus.

      The advantages to a serial system are:
      1. No timing skew. With a high speed parallel bus, you have to insure that all the data paths are the same electrical length, or else some bits get to the card before other bits, and you have to reduce the clock rate to prevent errors. With a serial system you have far fewer lines to worry about.
      2. Simpler board design. When you are dealing with a 64 bit data bus, 64 bit address bus, plus control lines, the board design gets a bit complex. With a serial system, you have less than ten lines per channel - a much simpler board layout.
      3. Serial systems usually use a MUCH lower signaling voltage, resulting in MUCH lower EMI and on-board noise.
      4. PCI express allows you to gang serial channels for more bandwidth. Video card saturating one channel? Use two.
      5. Unlike AGP, PCI express is a bus - so each device can busmaster to system memory or to other cards as needed. This helps you when your video card wants to store textures in system RAM rather than on-card. Imagine how much fun John Carmack could have with a video card that can support 1G of textures.
      6. It is far easier to design disconnects for a serial bus, thus allowing for PCI hotswap. In fact, the PC card group is working on a new standard for PC cards (nee PCMCIA) that brings 2 PCI-X channels to card - Cardbus on steroids.
      7. It is possible to route a PCI-express channel out of the computer case to an external chassis. While this is of limited use to the usual computer user, for guys like me [aeroflex.com] it is a boon to be able to have an external chassis that looks just like it is on the main system bus, because it IS.


      PCI express *could* allow you to have a computer that has bays that accept anything - hard disk, video card, extra CPU, NIC, whatever, and plug them it without restarting (unless you are running Windows (cheap shot, as I beleive MS is working on fixing that)). It will allow your video card to REALLY have fast access to system RAM, and especially in 64 bit systems, that could be a LOT of system RAM.

      Good stuff - I can hardly wait 'til it becomes commonly accepted.

        # PCI express allows you to gang serial channels for more bandwidth. Video card saturating one channel? Use two.


        Now, I'm no EE, but if you're trying to simplify the bus by making it serial instead of parallel, aren't you just reintroducing all of the problems by parallelizing it again? And now making it worse by having to sync the timing on two seperate buses? Just curious, if someone could explain...

          Actually, the single bandwith of one link isnt that big. See the story, they use 16Links for Graphics.

          But hypertransport is the same in that reagard. Its MUCH easier to run x links a y bits than one link with x*y bits.
          For Example, you have your own clock line for every link, so there is no need for temporal coherence between the links. At Ghz-speeds in copper on a pcb, a few millimeters lenght difference would be enough to kill your signal. But of course you cant put the lines to close to each other because of crosstalk, ect.
          With multiple seriel busses, you just give every link a big enough fifo at each end and no problems...

        As another poster stated, this in unlikely to happen.

        High-performance graphic cards will require a x16 slot, and most motherboards will only provide one x16, multiple x1 and maybe a couple of x4.

        Moreover the PCI-Express specs define power limits. All the Gfx vendors requested (and got) amazingly high power limits for graphic slots. Having two Gfx boards working at the limit would blow past the cooling abilities of most cases. While it will be possible for a PC manufacturer to provide multiple such slots, this will not happen in the value segment and may only be offered at a high cost premium (if at all).

        What I am hoping for is for "secondary" cards working from a 4x slot, with limited performance and limited consumption. I could use a (or two) secondary display(s) while using flight simulators (e.g., for auxiliary panels or peripheral vision).

        Note also that the PCI-SIG is close to making a decision on "second generation signaling rate". The debate is between 5Gb/s/lane (ie 2 times Gen I) or 6.25Gb/s/lane. A Gen-II 4x slot would provide enough bandwidth to feed a current high-end card.

    PCI-E is not about more performance. In fact, a well designed PCI-E card will not show any real deficit in performance vs. an AGP one, provided all other variables are identical.

    PCI-E is about making the video processor useful for more than just dumping graphics data. Modern graphics chips are essentially giant geometry calculators, and could be used for far more than they currently are. Due to the fact that PCI-E allows data to be communicated back to the system after it has been processed on the card, this opens up a whole new realm of possibilities. Many 'glitches' in current rendering techniques should dissapear now that the card can relay what the output looks like back to the game driver, allowing it to make on the fly corrections to the image.

    PCI-E is all about features, not performance. It should perform like any other interface really, maybe a couple percent faster due to the increased bandwidth, but nothing major. I doubt games will truly begin to take advantage of it for a couple years. Upgrading right now to get PCI-E is ridiculous, however buying a top of the line AGP card at this juncture is equally ridiculous...

      Using the host processor "to make on the fly corrections to the image" would be madness as you would have to transfer the whole frame buffer off the GFX card to host mem and then back again. An incredible waste of bandwidth when you can do pretty much most things with pixel shaders anyway, without the round trip.

Frame-buffer issues aside, things like Apple's Quartz Extreme are quickly re-defining what 2D is and isn't, thanks to new features that are a combination of 2D/3D. Expose is a prime example, requiring upwards of 64MB of VRAM in extreme cases(high resolution, a dozen+ windows to compose), and a full 128MB(the quantity of memory high-end cards come with) if you do that with 2 displays. Longhorn is expected to bring a similar situation to the table, so what's been true for nearly the last decade, isn't going to be true for much longer.
