Yes and No. On one hand it depends on the chip generation, operating system, driver and system configuration. Most of the current generation Intel GPUs have a hard limit at either 32 GB or half the amount of RAM installed in the system, whichever is lower (see [1]). On the other hand the operating system must have free RAM left when the GPU driver wants to allocate some more. Could you maybe post the output of the clinfo command (Linux distributions have it in their repositories, Windows version here [2] at the bottom)? On my ASUS notebook with an Intel Graphics 620 and 16 GB of RAM it reports ~6 GB for "Global memory size" and 2 GB for "Max memory allocation" when the system is idle. I see that most ThinkPad X1 Carbon with the Intel Graphics 520 seem to have shipped with 8 or 16 GB of RAM. Since the Intel OpenCL driver really seems to report slightly less than 512 MB in your case, there is probably a reason for that. kind regards, Simon [1] https://www.intel.com/content/www/us/en/support/articles/000020962/graphics-drivers.html [2] https://github.com/Oblomov/clinfo ___________________________________________________________________________ darktable developer mailing list to unsubscribe send a mail to [email protected]
