This wireless eGPU claims to deliver RTX 5090-like performance over Wi-Fi

Cyberpunk 2077 was shown running at more than 90 fps over Wi-Fi 7
First look: External graphics cards have so far been limited by their need for high-bandwidth ports such as OCuLink and Thunderbolt 5. WiCi aims to address the issue by transmitting a GPU's horsepower over Wi-Fi. The company claims that multiple devices on a network can share an eGPU's compute for gaming and AI workloads.

Raspberry Pi 5 runs Doom 3 at 4K using an external GPU

The Pi 5 can handle PCIe 3.0 speeds and fairly old AMD GPUs
WTF?! The Raspberry Pi 5's expanded PCIe functionality is one of its most enticing upgrades over its predecessors. Most owners likely use it to install fast storage, AI chips, or network cards, but modders have successfully connected it to dedicated graphics cards. Although the Pi isn't a gaming PC, installing a GPU on one could unlock interesting possibilities.

Thunderbolt alternative OCuLink tested for eGPUs, Nvidia's RTX 4090 benchmarked

In context: For those unfamiliar with OCuLink, it is an optical interface developed over a decade ago, primarily for servers. However, it has recently gained attention for consumer uses, such as external GPUs. OCuLink offers higher bandwidth compared to Thunderbolt 4 – up to 64 Gbps versus 40 Gbps. This increased bandwidth opens up the possibility better eGPU performance compared to Thunderbolt.

FEATURE By Tim Schiesser, TechSpot Hardware

Last year, we briefly looked at external GPUs when we reviewed the Aorus GTX 1070 Gaming Box attached to a Kaby Lake-powered ultraportable. Now that Intel's 8th gen CPUs are widely available in a range of ultrabooks, with significant performance gains in hand, it's the perfect time to revisit eGPUs and determine whether the hard CPU bottleneck still exists in most games.
