Тест Intel Pentium G840

Скорость в играх

Производительность Intel Pentium G840 в играх и подобных приложениях, согласно нашим тестам.

Наибольшее влияние на результат оказывает производительность 4 ядер, если они есть, и производительность на 1 ядро, поскольку большинство игр полноценно используют не более 4 ядер.

Скорость в офисном использовании

Производительность в повседневной работе, например, браузерах и офисных программах.

Наибольшее влияние на результат оказывает производительность 1 ядра, поскольку большинство приложений использует лишь одно, игнорируя остальные.

Скорость в тяжёлых приложениях

Производительность в рендеринге, кодировании видео, работе с виртуальными машинами и базами данных.

Наибольшее влияние на результат оказывает производительность всех ядер и их количество, поскольку большинство профессиональных приложений охотно используют все ядра и соответственно увеличивают скорость работы.

Данные получены из тестов пользователей, которые тестировали свои системы как в разгоне, так и без. Таким образом, вы видите усреднённые значения, соответствующие процессору.

Скорость числовых операций

Мин.	Среднее	Макс.
46	1 ядро 68	74
79	2 ядра 130	147

Мин.	Среднее	Макс.
93	4 ядра 133	147
100	8 ядер 135	147

Для разных задач требуются разные сильные стороны CPU. Система с малым количеством быстрых ядер отлично подойдёт для игр, но уступит системе с большим количеством медленных ядер в сценарии рендеринга.

Мы считаем, что для бюджетного игрового компьютера подходит процессор с минимум 4 ядрами/4 потоками. При этом отдельные игры могут загружать его на 100% и тормозить, а выполнение любых задач в фоне приведёт к просадке ФПС.

В идеале покупатель должен стремиться к минимум 6/6 или 6/12, но учитывать, что системы с более чем 16 потоками сейчас применимы только в профессиональных задачах.

Данные получены из тестов пользователей, которые тестировали свои системы как в разгоне (максимальное значение в таблице), так и без (минимальное). Типичный результат указан посередине, в цветной полосе указана позиция среди всех протестированных систем.
