Title: OCulink all set to become mainstream thanks to upcoming Lenovo ThinkBook 14p 2024 with Meteor Lake
Post by: Redaktion on December 25, 2023, 17:39:45
Lenovo is apparently planning a refresh to the ThinkBook series next year with Intel Meteor Lake processors. The ThinkBook series will be comprised of the ThinkBook 14p, ThinkBook 16p, and the ThinkBook 13x convertible alongside a ThinkBook Plus Android tablet. The ThinkBook 14p is particularly interesting as it is touted to feature an OCulink port that offers a much faster connection to eGPUs over Thunderbolt 4.

Talking about 16GB/s and later talking about the speed depending on the implementation is pretty confusing.

Fact is: OCulink offers 4 lanes of PCIe and the standard at which it operates is flexible.
With 5.0 the speed is about 4x what thunderbolt 4 offers for PCIe devices.

OCulink supports "up to" 16 GB/s. The implementation is important as earlier Dell XPSs with Thunderbolt only offered 20 Gbps throughput although the standard itself can go up to 40 Gb/s. Implementation varies depending on a host of considerations including but not limited to power specs of the device, cable length, possible electromagnetic interference (as in the case of the GPD Win Max 2) etc.
