RIITOP OCuLink eGPU Dock Review

RIITOP OCuLink eGPU dock, 64Gbps SFF-8612, PCIe 4.0 x16 support, budget external GPU enclosure sold on Amazon

RIITOP is a smaller accessories brand selling budget OCuLink and USB4 eGPU docks directly through Amazon, offering full PCIe 4.0 x16 card support at 64Gbps OCuLink bandwidth for buyers who want the cheapest entry point into external desktop-card graphics.

Overview

RIITOP's OCuLink dock is a minimal, low-cost enclosure with no built-in PSU convenience or extra ports, built for price-sensitive buyers who already understand OCuLink's PCIe 4.0 x4 bandwidth trade-offs.

Comparison to Alternatives

It undercuts the AOOSTAR AG01/EG01 and Zima OCuLink dock on price by skipping a built-in PSU entirely, making it the most budget-oriented option in this catalog's OCuLink category, at the cost of the convenience and brand track record of AOOSTAR, UGREEN, or Zima.
