Новый 22 nm техпроцесс благоприятно сказался на энергоэффективности процессора. Хотя TDP не изменился, потребление энергии и тепловыделение уменьшились. Ядра новой архитектуры немного мощнее, к тому же теперь их 10, а не 8. Увеличился и кэш третьего уровня, теперь он составляет внушительные 25 мб.
Появилась поддержка DDR3 (включая ECC) с частотой вплоть до 1866 Мгц, ранее такую частоту можно было получить только разгоном.
К сожалению, увеличения тактовой частоты не произошло, более того, она сократилась на 100 МГц и составляет теперь 2.5 ГГц против 2.6 у 2670 v1.
Производительность и разгон
Несмотря на меньшую частоту, в целом, производительность увеличилась примерно на 10-15%. Заметно выросло многопоточное быстродействие, благодаря увеличению количества ядер. Single-core производительность тоже стала посильнее, тут сыграл кэш и новая архитектура.
С современными играми процессор справляется хорошо, редкие исключения могут составить сильно процессорозависимые игрушки, но таких крайне мало. Количество кадров можно увидеть в видео. Стоит учесть, что процессор в небольшом разгоне, а видеокарта — nvidia 970, Xeon e5 2670 v2 может спокойно работать и с более мощными картами.

Недавно встал вопрос о приобретении нового компьютера для работы. Необходимо было обеспечить максимальную производительность в программах для научных расчетов. Поэтому было решено собирать двухпроцессорную систему на базе процессоров Xeon E5-2670, по 8 ядер каждый. Этот некогда дорогущий процессор сейчас можно найти на Ali за 85 долларов (реферальная ссылка).
Прежде чем мне удалось его получить прошло много времени и нервов. Первый продавец, у которого я заказал процессоры не отправил его в течении 10 дней и деньги вернулись на карточку (еще через неделю), второй продавец сказал, что отправил, дал фейковый трек-номер и не получив ничего через месяц был открыт спор, деньги вернули. Третий продавец уже оказался честным и я получил свои процессоры через неделю после отправки. Суммарно после первого заказа прошло уже 2 месяца. Сделал для себя вывод - не покупать товары, по которым вообщ
е нет отзывов у продавца или отзывов мало.
Материнскую плату
на 2 сокета 2011 покупал отдельно на www.computeruniverse.net
за 250$.
Наконец-то процессоры приехали, поставлены на свои места и можно приступать к тестам.
Конфигурация тестового компьютера:
- Процессоры Intel Xeon E5-2670 (2 шт)
- Кулеры ZALMAN CNPS10X Optima (2 шт)
- Мат. плата Asus Z9PA-D8
- Память 64 Гб DDR3 1333 Мгц
- Видеокарта GeForce GTX 660 2 Гб
- SSD Samsung 850 EVO 250 Гб
После установки процессора были сделаны тесты производительности с включенной технологией Hyper-Threading (делает из одного реального ядра 2 логических), тоесть система видела 32 ядра (2 проца * 8 ядер * 2 потока) и с выключенной HT, 16 ядер (2 проца * 8 ядер). Тесты показали, что более высокое быстродействие без HT. Отсюда вывод - если нет каких-либо специфических требований, технологию Hyper-Threading лучше отключить.
Тесты производительности
Для начала что нам скажет тест производительности
Windows 7
:
По всем параметрам максимум 7.9, по процессору - 7.8. Непонятно как так получилось.
Далее проверим процессоры утилитой
CPU-Z.
Общая информация:
Тест производительности:
Производительность на 1 ядро всего на 20% выше моего старого Core2Duo E8400 (обзор его апгрейда). Зато полная мощь впечатляет.
Проверим систему встроенным тестом WinRar , который тестирует скорость архивирования и отображает производительность в реальных задачах:
Тут производительность на 1 ядро почти в 2 раза больше, чем у моего старого E8400 (скорее всего дело в количестве кэша), при подключении всей мощности ожидаемый прирост.
Также прогоним популярный тест
Cinebench R15
, который тестирует скорость рендера.
Xeon на первом месте, в сравнении нет i7 6700, он примерно соответствует двум E5-2670, но стоит в 2 раза дороже.
Для тестирования быстродействия в повседневных задачах воспользуемся
PcMark 8
, который замеряет скорость отрисовки страницы веб-браузером, редактирования фото, отображения потокового видео, редактирования таблиц и т.д. в режиме Home.
Также замеряна скорость работы с
Word
,
Excel
и
PowerPoint
. PcMark 8 позволяет тестировать скорость работы этих пакетов, если они установлены на компьютере.
Тут результаты вполне заурядные, при домашнем/офисном использовании высокой скорости не будет, так как большинство приложений не оптимизированы под многоядерность.
В играх никаких тестов не проводил, так как компьютер исключительно рабочий, да и обзор посвящен процессорам, а не видеокарте.
Выводы
Для людей, которым необходимо большое количество вычислительных потоков
(рендер, расчеты и т.д.) данные процессоры являются оптимальным решением по соотношению цена/производительность
.
Для игр это абсолютно бесполезное приобретение
, так как в играх от процессора важна производительность на 1 ядро, которая тут не очень большая, а половина ядер Xeon"а в играх будет просто простаивать.
