CASH ONLYPICKUP ONLY (No delivery/No shipping) Pickup Location: Very close to North York Centre Subway Station Welcome to test: You are welcome to test the graphics card dock and check its functionality upon pickup to ensure everything works properly and to your satisfaction! Please feel free to contact me if you have any questions! The core advantages of OCuLink over Thunderbolt 4 lie in its higher effective data bandwidth, lower performance loss, and lower hardware deployment costs. 1. Higher Actual Data Bandwidth (No Protocol Segmentation): Thunderbolt 4 theoretically has a total bandwidth of 40Gbps, but the dedicated bandwidth allocated to PCIe data transmission is limited to 32Gbps. Pure PCIe Lane: OCuLink (PCIe 4.0 x4 specification) has a full 64Gbps effective bandwidth, twice the actual data bandwidth of Thunderbolt 4. 2. Minimal Graphics Card Performance Loss (No Chip or Conversion): Thunderbolt 4 signals require encoding by the motherboard's control chip during transmission and decoding at the external graphics card dock, resulting in higher latency and performance loss. Native Direct Connection: OCuLink directly brings out the motherboard's native PCIe lanes, representing a true hardware direct connection. When using a mid-to-high-end external discrete graphics card (eGPU), game frame rates and AI training efficiency are significantly higher than with Thunderbolt 4. 3. Lower hardware and accessory costs: No need for licensing or control chips. Thunderbolt 4 requires Intel certification and the graphics card dock motherboard must be equipped with an expensive Thunderbolt controller chip. Simplified structure: The OCuLink solution does not require complex control chips. Commercially available OCuLink graphics card docks or adapter boards have a simple structure, making them more affordable overall than Thunderbolt graphics card docks.
