My god, IB bandwidths always confuse me. :-)
I thought IB SDR was 10 GB/s signal rate and 8 Gb/s data rate. How do
you squeeze ~1400 MB/s out of 8 Gb/s?
I see you offer Lx cards in PCIe 4x and 8x. Again, PCIe is encoded at
10bit/8bit so the data rate is 8 Gb/s. So the above value is for your
8x cards only, no? The thread is about your 4x cards, no?
Are there many PCIe Gen2 motherboards yet?
