an external monitor attached directly to the eGPU is required to maximise performance on the narrow 4Gbps eGPU bandwidth ( reference).16Gbps (x4 2.0) deemed necessary to hit 85% desktop-level performance ( reference). it’s 4Gbps of bandwidth delivers compromised performance compared to a desktop, 32Gbps-TB3, 16Gbps-TB2 or 10Gbps-TB1 Thunderbolt system.availability of an affordable EC2 eGPU adapter starting at US$6ĨGbps – x1 3.0 (6th gen i-core CPU or newer)ĢGbps – x1 1.1 (1st gen i-core CPU or older).Comparatively, Thunderbolt is PCIe interposer silicon so can present more challenging eGPU detection issues. is a direct PCIe interface often yielding a plug’n’play solution, or may require minor Windows error 12 tweaking.Important due to NVidia’s GTX10xx cards requiring this for functionality which prevents mPCIe/M2 wifi or PCIe SSD slot interfaces from being used to host a eGPU ( reference). 3rd/4th-gen quad-core systems still performance competitive against even the newest 7th gen quad-core equivalents ( example). Many are durable business grade systems being offloaded by companies, still in good condition, on the second hand market. ready availability of cost-effective EC2 candidate notebooks.Update: four (expensive) 7th/6th generation Lenovo workstations have a rare Expresscard 3.0 (8Gbps-EC3) port here. Here ◄ are eGPU.io user submitted EC2 eGPU implementations as an additional reference.

In this article you’ll find the pros, cons, adapters and a full listing of EC2 equipped notebooks including recommended notebooks provided to help decide if this is the right eGPU interface for you. Right: A HP 2560P 4Gbps-EC2 eGPU implementation using an ATX PSU to drive a NVidia cardĮxpresscard 2.0 (EC2 or 4Gbps-EC2) is a lower cost and lower bandwidth eGPU interface alternative to Thunderbolt found in older 2011-2013 PC notebooks.
