Audio Cards - PCI-e Vs PCI 2.1

Steve Erickson, vice president for Creative's audio products , has explained why new powerful and high performance Sound Blaster Cards are not available in PCI-e technology:

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.
