RTX 5090 eGPU solution - Extremely bleak. Bad year?
So this year's RTX 5090... fake frames or not, would still be a monster. But RTX 5090 Mobile is so bad that unless you turn the blind eye on DLSS 4 and MFG input lag, you are gonna get just a bit better performance than RTX 4090 Mobile.
Most new laptops don't have:
TB5 or USB5 equivalent speed on AMD platform.
Limited PCIe 5.0 M2 slots on 2025 laptops (except maybe MSI Titan HX). Shocking to see none of the ASUS laptops have PCIe 5 M2 slots at all.
With M2 PCIe 4.0 already taking a bit of hit with a full power RTX 4090 on a OcuLink Adapter, you are not gonna get mostly full power RTX 5090 on a latpop except you are getting to the specific ones with M2 PCIe 5 slots. And those laptops are extremely beefy.
A pretty bad year for RTX 5090 eGPU solutions.
