ONEXGPU 2, an external graphics card with Oculink and USB4 based on the Radeon RX 7800M

The technology to have external graphics cards in laptops and other devices has existed for many years. The evolution of connection systems has made it possible to have greater bandwidths that reduce the performance penalty compared to direct PCI Express connection.

Oculink in a connection standard capable of achieving the same bandwidth as a PCI Express 4.0 x8 port thanks to a cable that combines optical connectivity with traditional copper. There are still not many graphics models available with this technology, and large manufacturers seem to prefer proprietary solutions.

The new ONEXGPU 2 It is a model that has been launched in funding campaign on indiegogo and that has a AMD Radeon RX 7800M with its 60 CUs, 4,840 SPs and 2,145 MHz of operation. It offers 12 GB of GDDR6 memory. It has a compact size and has its own cooling system and a 330W power supply more than enough to power this GPU (which has a maximum consumption of 180W in Boost mode).

It also includes “dock” functions, with a USB 3.1 type A HUB, two DisplayPort 2.0 and an HDMI 2.1. In addition, it can also work with USB4 40Gbps for those devices that do not have the Oculink port.

In addition, it has a microSD reader and up to an M.2 port for PCIe Express SSD.

However, the ONEXGPU 2 It does not escape one of the main problems of this type of external graphics cards: its price. Although we are talking about a laptop GPU, and not the top-of-the-range models, its official price when it goes on sale will be $999, with $839 for those who purchase it through a financing campaign.
