Therefore a PCIe x16 interface is capable of (8 GT/s * 16) – 2/130% or 15.7538 GB/s whereas a PCIe x4 interface is only capable of 3.938 GB/s. A PCIe Gen 3 interface has a per-lane data transfer rate of 8 gigatransfers per second (GT/s) but the bandwidth is reduced by 2/130 percent because it uses an encoding scheme. In a desktop PC, the discrete graphics card typically uses the PCIe x16 Gen 3 slot on the motherboard, and although Gen 4 slots are becoming available they are not necessarily required at this stage for gaming. Without going into too much detail a brief explanation of the underlying technology is useful in understanding why performance is impacted. Use a GPU in a ‘PCIe x16 to M.2 NVMe adapter’ installed in an M.2 NVMe slot and either reuse the NVMe SSD by installing it in a ‘USB to M.2 NVMe adapter’ connected via a USB port or use external storage connected via a USB port.Use a GPU in a ‘PCIe x16 to M.2 NVMe adapter’ installed in an M.2 NVMe slot and either reuse the NVMe SSD by installing it in a ‘Thunderbolt 3 to M.2 NVMe adapter’ connected via a Thunderbolt 3 port or reuse the NVMe SSD by installing it in a ‘USB to M.2 NVMe adapter’ connected via a USB port or use external storage connected via a USB port.Use a GPU in a ‘PCIe x16 to M.2 NVMe adapter’ installed in a ‘Thunderbolt 3 to M.2 NVMe adapter’ connected via a Thunderbolt 3 port or.Use a GPU in an ‘eGPU’ connected via a Thunderbolt 3 port or.

Unfortunately, not many Chinese-made mini PCs currently include a Thunderbolt 3 port however now that they have started to include M.2 NVMe ports this has created the possibility of adding a GPU using a ‘PCIe x16 to M.2 NVMe adapter’.Įxamples of the various options available for using a GPU with a mini PC including the choices of configuration and performance impacts especially on gaming are discussed below. Lower-priced laptops often share the same drawback and one of the ways that users have addressed their graphical need is by utilizing an external GPU (eGPU) however the commercially available ones are both expensive and require connecting via a Thunderbolt 3 port. However, one drawback is their limited graphical performance due to using CPUs with integrated graphics which results in the options for playing games being somewhat restricted and ‘AAA’ titles typically being unplayable. As such they are useful both in commercial settings such as digital signage as well as with consumers needing a small-footprint or VESA-mounted low-cost computer.
Mini PCs have grown in popularity in part due to their small form-factor offering low-powered basic computing with sufficient ports for connectivity.
