"Performance Impact: OCulink's Effect on GeForce RTX 4070Ti SUPER vs. RTX 4090"
The introduction of the OCuLink connector has expanded external GPU options for consumer products, allowing direct connection to high-end desktop GPUs like the RTX 4070Ti SUPER and RTX 4090. However, recent tests show that when connected to a laptop and displaying images directly on the laptop monitor, the RTX 4070Ti SUPER experiences a 9.8% performance loss, while the RTX 4090 suffers up to a 22.6% loss. Connecting the discrete GPU directly to an external monitor provides better performance, with a lower loss of just 16.6%. The performance decrease varies based on the benchmark, but overall, external GPUs using OCuLink face similar bottlenecks as Thunderbolt-connected graphics, albeit with less performance penalty.
