Intel Core i7-820QM

Intel 820QM

Intel Core i7 820QM - производительный четырёхъядерный процессор, представленный в 2009 году. Он использует четыре физических ядра, способных производить вычисления одновременно в 8 потоков благодаря технологии Hyper-Threading.

Максимальная частота 820QM - 3.06 ГГц, она автоматически изменяется в зависимости от интенсивности вычислительной нагрузки. Процессор поддерживает работу с памятью DDR3-1066 и DDR3-1333, его тепловыделение (TDP) укладывается в 45 Вт.
