Lightweight External GPU is First to Use OCuLink Connector

GPD is crowdfunding campaign It is reported to design and build the world’s first external graphics processing system with AMD’s Radeon RX 7600M XT GPU inside, with OCuLink and USB4 interfaces to connect to the host. note check. Once this unit is developed and brought to market, he promises to be one of the industry’s smallest eGFX solutions.

At 225 x 111 x 29.8 mm, the GPD G1 claims to be the world’s smallest external GPU with laptop dock capability. The unit is powered by AMD’s Radeon RX 7600M XT notebook GPU with 2048 stream processors, 32MB Infinity Cache and 8GB GDDR6 memory, delivering up to 100% performance comparable to desktop Radeon RX 6650 XT or Radeon RX 6700 Promised to deliver 21.4 FP32 TFLOPS. , according to, only independent testing reveals its true functionality.

The unit features two DisplayPort 1.4a, one HDMI 2.1, an SD 4.0 card reader, three USB 3.2 Type-A, one OCuLink (SFF-8612) connector and one USB 4 (Type-C) port. It offers various ports including: . The box packs a tiny 240W GaN power supply, so it’s as small as no extra power brick and weighs only 0.92 kg.

Perhaps the most mysterious part of the GPD G1 is its interface. On the one hand, it has the ubiquitous USB4 interface, as it is compatible with many PCs already in use with Thunderbolt or USB4 ports. On the other hand, there is also an OCuLink connector that offers similar functionality, but is rarely found on laptops. In fact, when connected using an OCuLink cable, the GPD G1 even disables the USB Type-A port and SD slot as OCuLink is intended to support PCIe protocol only. USB4, on the other hand, both offer higher bandwidth and better features, so most GPD G1 users are likely to take advantage of this connection.
