does a PCI-e accel cards outperform PCI-accel?

[cajonezzz]

Just wondering if there was any functional difference between PCI-e based Accel cards and PCI-(x) ? any benchmarks done here?

PCIe have very slightly "less" power than PCIx.......


Differences Between PCIe and PCI-based Pro Tools|HD Systems

• The PCIe HD Accel card uses a combination of the chip-types used on the Core and
Accel PCI cards

• This gives the PCIe version more processing power than a PCI Core, "and a little less
than a PCI Accel."

• In larger systems (HD 3 and greater), this difference is insignificant.

• In smaller systems (HD 1, HD 2) there are some noticeable differences, but for many
typical sessions using a combination of different algorithms, the differences are
minor.

Yeah but the pcie core cards have more processing power than the PCIx core cards and can also run Accel only plug-ins.

Here's the tech doc's..

The way it was explained to me by Digi was if you go with an HD1 comparison, the PCIe will be more powerful than the PCI because the CORE card on the PCIe side is actually an Accel card, whereas the PCI version is not.

However, the PCIe is slightly less powerful than the PCI cards are and if you go with an HD|3 Accel rig, no matter if it's PCI or PCIe the power will be virtually identical between the two. So, it all evens out.
