Mini PC’s built with e-Gpu’s in mind have occulink but it’s limited to x8. BeeLink released the GTI with a full length slot but it’s also limited to x8.
The specs on these mobile CPUs seem to have enough lanes. Even adding up the radios, SSD, etc it seems like there should be enough for a full x16 eGpu. Can someone explain what the issue is?
Thank you!
Mostly due to market segmentation… If you need an x16 slot then they want you spending more.
The other reason is probably because most people just want their GPU to use x16 because big number = good but the performance impact of running at x8 is often impossible to notice without benchmarking. So if manufacturers can offer even a bit cheaper product by only supporting x8 then they will.
I think OCuLink is even lower than x8 with a max bandwidth similar to gen 4 x4.
A 4090 limited to x8 drops quite a bit of performance.
It just seems odd to me that a company like Beelink would go out of their way to design a motherboard (smaller than Mini ITX) that is the first mini PC to have a full PCI-E but then they limited it to x8. Odd indeed.
Sure but devices that need 16 lanes are not very common. An x8 electrical x16 slot covers most uses.
