What's the bandwidth and form factor for PCIe x1 x4 x8 and x16?
April 26, 2023 by Pratik. A head-to-head speed comparison will indicate that PCIe is the obvious winner. With the current trending PCIe generation v4.0, you can get a throughput rate (speed) of about 2 GB/s on an x1 slot and about 32 GB/s on an x16 slot. Compared to this, the current SATA v3 only offers a max of 0.75 GB/s (6 Gigabits per second).
PCIe x1 vs x4 vs x8 vs x16 (Size, Bandwidth, Compatibility)
PCI. 133 or 266MB/s (depending on bus speed) PCI-X. 266-4,266MB/s (depending on bus speed) AGP 2x. 533MB/s. PCIe x1. 250MB/s (in each direction) PCIe x2. 500MB/s (in each direction) PCIe x4. 1,000MB/s (in each direction) PCIe x8. 2,000MB/s (in each direction) PCIe x16. 4,000MB/s (in each direction) PCIe x32. 8,000MB/s (in each direction)
PCI Express - Wikipedia
Though, in recent years, x1 slots have been taking on more demanding tasks, because an x1 slot on a PCIe gen 4.0 or 5.0 motherboard offers impressive speed. PCIe x4. This port is not so common on desktop range motherboards. Motherboard manufacturers usually prefer to put more PCIe x1 ports than x4 because there are not many expansion card ...
PCIE1.0-6.0 Interface Bandwidth & Speed Calculation - DiskMFR
Lindsay Hayes. PCIe X1 slots are used to connect expansion cards, like sound cards, USB port expansion cards, network cards, TV tuner cards, and even video capture cards to the motherboard. They're smaller compared to other PCIe slots, so are perfect for expansion cards that have lower bandwidth requirements.
PCI Express x1 Slot Speed | Tom's Hardware Forum
PCIe 1.0/2.0/3.0/4.0/5.0 Interface Speed Rate. PCIe Concepts. Transfer speed is GT/s, not Gbps, as the transfer contains overhead bits that do not provide any additional performance. For example, PCIe 1. x and PCIe 2. x use an 8B/10B encoding scheme, resulting in 20% (= 2/10) of the original channel bandwidth.
PCIe speed table (from gen 1 to gen 6) - NAS Compares
In the case of PCIe x1 devices, whether or not all of the bandwidth available is being used will depend on the device in question and even the generation of PCI Express being used, due to the generational differences between PCI Express bandwidth. What Devices Use PCIe x1 Slots? So, what are PCIe x1 slots used for?
What are PCIe X1 Slots Used For? Ultimate Beginner's Guide - DigiChasers
The bandwidth for each PCIe 4.0 lane is 2 GB/s. 2 GB/s per lane means that if you use a PCI-Express 4.0 x16 device, it would have up to 32 GB/s of bandwidth available to it. NVMe M.2 SSD cards use 2 or 4 lanes, which means they have 4-8 GB/s available to them with PCIe 4.0. Samsung 980 1 TB M.2 SSD Check Price on Amazon Amazon Affiliate Link.

As it's the shorter variant of x1, Mini-PCIe only contains a single Lane bus, but the bandwidth speed can vary according to the PCIe generation of your motherboard. However, once the users have understood the important aspects and major differences among each format and PCI Express version, then it becomes all easy to realize the difference.
