Please Note: This is a Xilinx Hardware Evaluation Kit
The PassMark PCIe Gen3 Test Card is built with a Xilinx hardware evaluation kit. As such the warranty from Xilinx is 30days. These are expensive parts and are NOT suitable for high volume production line testing. We strongly recommend testing suspect PCIe slots with cheaper disposable hardware (e.g. GPU or NIC cards or short circuit tester) before using this card in a slot.
PCIe Gen3.0 is normally quoted as 8GBps per lane. Why can't the PCIe Gen 3 Card Test at these speeds?
Yes, PCIe Gen3.0 is normally quoted as 8GBps per lane, however, data rates will never reach these speeds on a real device because some signalling bandwidth is used by bit encoding, TLP, DLLP and PLP overhead. On a correctly functioning PC with a single PCIe device connected, you should typically see measured maximum speed results shown in the below table:
|PCIe Gen3 Lane Width||Expected Speed|
The PCIe Test Card has a maximum bandwidth of 5500 MBps, so the card cannot benchmark up to the PCIe gen 3.0 maximum x8 bandwidth of ~7880 MBps).
