I would like to share my experince. Here is my system:
- Intel i7-3630QM 2.4~3.4 GHz 6MB Cache 4 Core 8 Threads 22nm
- Hyperx Impact 2x8 GB DDR3 1600 MHz ram (previously upgraded)
- dGPU Nvidia GT650M 2GB
- Hi-level 240 GB SSD + 1 TB HDD (previously upgraded)
New things for eGPU
- EXP GDC v8.5C mPCIe 50cm (I have bought it from local Turkey market (gittigidiyor.com). I supposed that it would come as v8.0, but the seller sent me the latest version)
- A used MSI RX 470 4GB DDR5 GPU.
- A brand new MSI RX 5500 XT 8GB DDR6 GPU. (for my desktop but tested with eGPU)
- Powerboost BST-ATX300 300W PSU
- Internal display 1600x900 pixels
A small hole was opened near the cover.
The cable was taped in case of the abrasion.
Made it strengthen with strong tape
I have discovered that the air flow of PSU makes the GPU cooler if it is placed closer. So I have designed a holding arms. Fans of the GPU runs rarely even if the load 100%. GPU temperature goes max 60 ºC. Around 57-60 ºC. I'm not sure if I put it into a box or just protect the fans.
It is suitable for both vertical and horizantal usage
I didn't see a super performance with RX 5500 XT as an eGPU. It is super on desktop but I don't recommend it fro eGPU for money saving. And also 4Gb is enough for many games. I have seen max 3.5GB usage only on Mount & Blade Bannerlord II. Otherwise mostly around 2-2.5 GB.
I must say that the turbo boosting is very pain in the ass for AMD GPUs. You have to add games and softwares individually into the graphic settings list.
Here is the test result with internal 1600x900 display @ ultra settings
- Battlefield 1 @ 30-35 fps (Vsync on, FXAA off)
- Heroes and Generals @ 40-60 fps (Vsync on, FXAA off, fast particles on)
- eFootall PES 2020 @ 30 fps (Vsync on)
- Euro Truck Simulator 2 @ 30-40 fps (Vsync on, Antialasing off, shadow quality low)
- Mount & Blade Bannerlord 2 Beta (Early access) @ 30-37 fps (Vsync off, FXAA off, shadow quality low)
I couldn't recorded because recording with full resolution at 30 fps makes FPS frop about 15-20. Because the CPU can't handle it.
