The eGPU, or external graphics processing unit, is a device that allows users to connect a desktop-grade graphics card to a laptop, effectively boosting its gaming or graphics performance. For years, eGPUs struggled with limitations like slow data transfer speeds and underwhelming performance, which made them less appealing. However, the introduction of Thunderbolt 5 has brought a new wave of interest in this technology. Ugreen, a hardware manufacturer, is capitalizing on this trend with its new LinkStation Pro, an upgraded version of its earlier eGPU model. The LinkStation Pro offers double the bandwidth of its predecessor, thanks to Thunderbolt 5, which provides data transfer speeds of up to 80 Gbit/s—twice as fast as the previous USB4 standard. It retains the semi-open aluminum case design of the original LinkStation, which helps with cooling and accessibility. The device also includes an OCuLink 64 Gbit/s backup port for laptops that support this type of connection. Inside, it can accommodate graphics cards up to 370 mm in length and 155 mm in height, including larger, triple-slot models. It features an integrated 850 W ATX 3.1 power supply, which eliminates the need for an external power source and can support high-end cards like the RTX 5090. Despite these improvements, the LinkStation Pro still connects to the graphics card via PCIe 4.0 x4, which is slower than the PCIe 5.0 x16 slots found in most desktop computers. This means that while performance gains are noticeable in some benchmarks, they may not be as significant with the very latest high-end graphics cards. The device also includes three Thunderbolt 5 ports and one USB-A 3.2 port, making it a versatile desktop hub. However, it lacks an M.2 slot for adding storage and an Ethernet port for wired internet connectivity. The LinkStation Pro is currently available for sale in China at a price of around 358 euros. There is no official release date for the product in Europe yet. Its use is limited to laptops and other devices equipped with Thunderbolt 5 or OCuLink ports, as older laptops with Thunderbolt 4 or USB4 40 Gbit/s will not be compatible. Mini PCs and some network-attached storage (NAS) devices can also benefit from this technology, expanding its potential applications beyond gaming laptops.
