| - | ===== Razer Core X eGPU ===== | ||
| - | I chose Core X over Core X Chroma when I ordered in November 2021 because the price difference between both cases was huge (220€ vs 365€) with the only benefit of an added 4 USB 3.0 ports and a 1Gbps Ethernet port. Although having those ports directly on the thunderbolt bus would be great and works well in Windows and MacOS it isn't so in Linux (as of 2020) due to a few bugs in the integration of the USB controller used in the Core X Chroma. | ||
| - | |||
| - | Another argument in favor of not choosing the Core X Chroma is that I believe it is best (in Linux that is, with current state of development) to separate power and eGPU on the dedicated thunderbolt bus and use another USB 3.0 adapter for Ethernet and eventually a few added USB ports. Such adapters are worth a lot less than the 150€ price difference between Core X and Core X Chroma and should work better together, as some users have reported issues with networking and USB hubs while tunneling PCIe to take advantage of the eGPU. That being said, the Thunderbolt implementation reserves a 10Gb/s bandwith specifically for other devices than PCIe (i.e. network, USB, etc.) | ||
