CUDA Device Query
Форум — Development
Приветствую!
Есть такая карточка у которой вроде бы 48 CUDA ядер
У Nvidia также написано, что задумано 48 CUDA ядер у этого чипа.
Однако /usr/bin/nvidia-settings говорит, что ядер 16.
И deviceQuery из CUDA-samples это подтверждает:

Result = PASSВопрос: Это офигевший вендор так кастрировал девайс, или я чего-то не понимаю?
