i thought that the x-fi sound card is supposed to be pci-e x1. and how long will the original pci slot last
As far as PCI Express (PCIe) is concerned, which is the next bus, what we found is that the performance of PCIe is truly bad for audio. We are seeing four times degradation on the bus for audio. PCIe is designed for graphics and high data transfer, but audio sends very small packets and the overhead can be very big! Moving the data across PCIe is much, much higher than PCI. So what we have to do is go back to the drawing board and work on the transport part of the chip and re-design it to add more silicon to overcome some of the problems we had with PCIe. So for us to come up with a PCIe solution is going to take a while because we have to overcome the problems we're facing with that bus.

What's with the current trend of wanting new busses, when the current ones are not even getting saturated by the devices on them?

To be fair it is quite possible to saturate PCI these days.What's with the current trend of wanting new busses, when the current ones are not even getting saturated by the devices on them?

Well that sucks. The card is a ripoff anyway..
Especially since the PCI bus is shared; 1 X-Fi may not completely saturate it, but it adds up in the end.Originally posted by: BFG10K

Why did we move to SATA for HDD's when PATA was fast enough?

As for Creative's PCIe comments...wow, I had no idea things were so grim.

True, we barely maxxed out AGP 8X. We are nowhere near maxxing out PCIE 16x!
And yes, the PCI bus can get saturated. Back in my SCSI days I had 2 PCI SCSI cards that were driving 18 SCSI HDs, and if more than 6 drives were in use the PCI bus crawled. I used to run the adaptec HD speed utlity to test the speed of each drive and when I had all 18 being tested the throughput was something like 10 mbs, and these were SCSI 320 LVD drives!

has the agp 8x even been maxed out? i was under the impression the 7800gtx cards don't saturate the 8x bandwidth, but it was more of a move to push us enthusiasts into new boards, cpus and now ddr2.
AGP Bandwith is not shared with PCI devices. In most chipsets the AGP is connected directly to the Northbridge whereas PCI devices are connected to the south.Originally posted by: The Boston Dangler

I guarantee the 7800GTX cards will not max out an AGP bus. I predict close to 0%.
But seriously, if an AGP version of the 7800GTX were to come out, it would nearly max out the bus. Especially since it is shared with PCI cards.

I really doubt it is; CL dragged their feet in a similar manner when coming out with a PCI sound card.Originally posted by: Woodchuck2000
I'd be interested to know why it's worse than PCI for audio applications though.

I'm building a new PC soon, so I want the latest and greatest. If the X-Fi is $60 more than an Audigy 2 ZS, I think I'll buy it.

I think ZZF has the zs for like $48 after rebate or something. It was $43 before.
Just letting you know the A2s have some nice deals out now.
