Not a surprise really. I wonder if PCIe might not be all Intel make it out to be?

meowCat said:How much is PCI Express faster than PCI? huh
no...ehZn said:...but in any case, do some research before posting plz. There's tons of information we don't need to post over and over about this.
And this explanation even ignores one of the best parts of PCIe: its serial, point-to-point (p2p ), switched nature, resulting in dedicated bandwidth per device. Whereas putting two PCI Gigabit NICs on a single PCI bus would pretty much saturate it, with PCIe each NIC would have its own channel ('bus') and would never have to fight for a chunk of bandwidth.Stiletto One said:I often tell people to do their research, but I also usually answer their questions first.
PCIe 1x = 250MB/s. PCI 16x = 16×250MB/s = 4000MB/s. Simple.
I don't remember where but it has been said that SLI will show up first on server MBs and then move into the consumer market which would make sense for a '05 Q1 release.oOo Foo said:I honestly can't see the transition to pci-e on AMD platforms taking that long. One really has to think that nVidia is pushing hard to get their SLI "nForce4" chipset out on to the market.....
It'll also mean that the Intel guys will be using PCIe first.CrimandEvil said:Although I'm a little disappointed (for the same reasons Elledan mentions) I'll also relieved. It gives PCIe time to mature alittle (as well as PCIe products to start showing up in good numbers) and me time to save some $$ for a whole new upgrade.
This is a common argument, but it's also completely false. We are reaching the limits of the AGP bus, only not in the way that many would expect. The point is that the AGP bus is asymmetrical, i.e., the amount of bandwidth to the videocard is far larger than the amount to the NB (and CPU). This means that a) it's easy to send data to the GPU, but far harder to retrieve anything, and b) videocards need far more RAM onboard to cache texture- and other data.Sc0rched said:I dont think either that PCIe will be fully capable till later when we reach the AGP max. Even right now (unless I am mistaken) that we dont even use up all the bandwith that AGP offers with the video cards.
You can't compare ISA and AGP in this manner. ISA was a general purpose bus, supporting any device compatible with the ISA-bus protocol. AGP only supports videocards.Plus my bet is that the companies will ever so slowly fade out AGP like they did with ISA. They kept making ISA motherboards/cards way after PCI came into play. The full benefit wont be avalible I would say even after Q1 of 05. Plus, if they are just getting the mobos out then for it on AMD, the next few gen. of cards will offer AGP because otherwise nVidia and ATi lose customers and money.

Fair enoughSc0rched said:Like I said unless I am mistaken... I wasnt sure for a fact, but I remebered reading somthing about it.
And my point was that it'll take far shorter for AGP to fade away. Not many people keep their old videocard when they upgrade their system, because by that time it doesn't even play the latest games at decent framerates, or they want to keep the old system in one piece (to sell it, or use it as a backup system, or make it the new system for the children, etc.).It might not last quite 5 years, but it will last a while longer. Corperations dont expect the everyone to go out and buy PCIe motherboards at one time, or not have a new video card. They will slowly fade it in over time. What I was trying to say is that PCI replaced ISA much like PCIe x16 is replacing AGP.
