Re: PT Video Peripheral Advice BM vs AJA
Quote:
I have never had a problem running HDX2 and a Blackmagic Decklink card in the same TB2 sonnet enclosure. We would be talking two PCIe 2.0 x4 devices for HDX2 and a PCIe 2.0 x8 device for the Kona 4. All up, it is 8Gbps for downstream, and 8Gbps for upstream. TB2 has 20Gbps of bandwidth each way... If we were talking GPUs, I definitely wouldn't want a x16 device sharing a thunderbolt bus bandwidth with anything else but video playback cards don't seem to work anywhere near as hard computing hard data into visuals.

Are you perhaps confusing the base clock rate of PCIe 2.0 at 5.0Ghz, with the total bus bandwidth of PCIe 2.0 at 8Gbps for a 16 lane device? I'm sure Sonnet know a thing or two about this, which is why they have included two x8 PCIe 2.0 slots and one x4 2.0 PCIe slot in the TB2 enclosure. The suggested setup will work totally fine.

PCIe 2.0 x 16 is 8GB/s not 8Gbps, it's 80Gbps with TB2 being only 20Gbps And here you're doing the same with Mbps, which is megabits/S. MBps or MB/S is megabytes/S. A PCIe 2.0 lane is 500MB/s not 500Mbps, it's 5000Mbps. Quote:

Thunderbolt 2 is essentially a PCIe 2.0 x 4 connection, so a PCIe 2.0 x 8 electrical connection video card such as Kona 4 will not be able to achieve its maximum performance over that connect. That may not necessarily even be a problem in your usage case, YMMV. Pete |
