But for most consumer desktop platforms, I believe the current state-of-the-art is a PCIe 3.0 x16 link that motherboard vendors can choose to do what they please with. Without knowing more about your application, I can't comment further, but generally the PEG lanes should be used for very bandwidth-hungry devices like GPUs or a PCIe packet switch that has many downstream devices.įor Xeon-based platforms, the numbers are very different - I believe now you can purchase a model with upwards of 40 lanes from the CPU. PCIe Device PCH CPU PCIe Root Complex.So, to summarize, you could design a product such that: They still deliver the performance you would expect, but they are generally x1 or x2 in width as the DMI link is a bottleneck. Other PCIe lanes on a platform are generally offered up by the PCH (aka southbridge), which is connected to the CPU via a DMI link. The key difference is that the PEG lanes offer the shortest possible 'hop' to the PCIe root complex. Industrial computers may route this link to a large PCIe switch which then breaks out into many smaller ports - this is what products I used to work on did. Your average desktop computer motherboard will route the PEG lanes from the CPU to either a single x16 slot, or twin x8 slots, obviously intended for GPU applications. This is generally the largest-width, fastest interconnect available. Generally, the PEG is implemented as a x16 link that can be (at least around Nehalem) also bifurcated into 2 x8 lanes - new models may support additional configuration. Since Sandy Bridge, the PCIe RC is a first-class member (so to speak) and enjoys connectivity to the high-speed interconnect on the CPU die (that also includes the DRAM controller, etc.). On most desktop x86 platforms, the PCI Express root complex is located inside the CPU itself, on-die. I Google searched 'COM Module Type 6 PCI Express' and it appears you're talking about the ADLink modules sold here, which are Intel based.
