Hi!
Has anyone tested the quality of the timing for visual stimulus presentation with an AMD advantage system with Ubuntu (or Windows)?
It would be great to hear about the results as we are considering to buy the following Laptop:
Lenovo Legion 7 16ARHA7 (82UH0008GE)
CPU: AMD Ryzen 7 6800H (8/16 · 3,2-4,7GHz · Radeon 680M 2,2GHz · 45W)
iGPU: AMD Radeon 680M (R6000 / 768 Shader / 2,2GHz)
dGPU: AMD Radeon RX 6850M XT (Laptop)
Thanks!
That laptop is a AMD dual-gpu laptop with very similar hardware to what was just handled in this thread:
As stated on our website, I do generally not recommend dual-gpu laptops of any make if avoidable, unless there is a good reason, but whereas they are generally or often unusable on MS-Windows, they can be made to work fine on Linux with some manual configuration and setup work, as demonstrated in the above linked thread. Still even on Linux a little bit more hassle than simply getting a single-gpu machine.
In general AMD gpu’s are not expected to have much of an advantage over NVidia on MS-Windows (whereas Intel gpu’s are entirely unusable on Windows timing-wise!). But on Linux they can have substantial advantages for visual timing, control, color precision, HDR, VRR, high quality open-source drivers. Also, I mostly only test on AMD, very rarely on NVidia.
