It’s all well and good to know how well something performs, but learning how it works will help really under stand PCIe 3.0.

If you’re a recording engineer, you can record more audio at once, as that digital audio can be processed quicker than it ever could before. So how could all that affect you? Simple - if you’re a gamer, PCIe being able to handle more data at a quicker speed means that more intense graphic cards can be developed the require a higher data transfer speed to work properly. You can also plug a PCIe 3.0 card into a PCIe 2.0 slot - however again the card won’t work up to its full speed. This is above the maximum bandwidth of the bus segment connecting switches 5 and 7, and will result in performance issues (lower/stuttering frame rate transfer) or will require the data to be pre-scaled before its transfer to the output.Of course, it’s important to note that the 16GB/s speed is only achieved when a computer can handle it - otherwise, while the card will work fine, it won’t be as fast as it otherwise could be. As an example, in the above illustration, if the 3 Mura IPX Series cards on switches 1 and 2 are capturing data to be displayed on the Mura MPX Series card connected to switch 3, up to 9 GB/s of bandwidth may be required (depending on the number of inputs and their resolutions).

When possible, inputs should be captured as close to the display card as possible to minimize system latency and maximize overall system bandwidth. The manner in which inputs are mapped to output boards can also have an impact. Placing many capture cards on the same bus segment may create bottlenecks that can hinder performance and lower the overall capture rate. This is done by ensuring that capture cards are (as much as possible) not all placed on the same bus segments. When installing many cards in a system like this, it’s important to maximize transfer bandwidth.
