Currently we are shipping with AVX disabled by default, and we always recommend customers reach out to us about any AVX workloads they want to run, as this is a much more complex instruction set and requires more fine tuning on a per customer basis. It generates more heat and consumes more power, which can introduce instability.
You can enable AVX and test your workload to see how this performs. You will need to monitor the following items and report back to us your findings to ensure the system is operating within acceptable ranges.
- Package power draw (can be measured via ‘turbostat’)
- PSU power draw (can be measured per module in the ‘sensor’ tab of IPMI)
- CPU package / core temps
- If possible, can you let us know a before-and-after for these stats also
You can enable AVX in the BIOS:
- Enter the BIOS by pressing «F2» during boot
- Navigate to «Ai Tweaker -> AVX Related Controls»
- Enable «AVX», «AVX512» as needed
- For light workloads, you will be able to leave the «Ratio Offset to per-core Ratio Limit» on «auto»
- For heavier workloads you may need to specify an offset. The values in the screenshot below are a good starting point.
Please note that Sapphire Rapids handles AVX workloads slightly differently to previous generations and instead splits AVX, AVX2, AVX512 workloads into light, medium, and heavy variations of each instruction set. See the table below for comparison. This means that a heavy AVX2 load may have the AVX512 offset applied for example.

По всей видимости, в скором будущем процессоры Intel Alder Lake полностью лишатся поддержки инструкций AVX-512. Это не такая серьёзная потеря для простых пользователей, как может показаться на первый взгляд, но сам факт отключения поддержки немного огорчает.
Это заметил и подтвердил ресурс Hardwareluxx. По его словам, производители материнских плат медленно, но уверенно выпускают обновления микрокода BIOS своих материнских плат, которые отключают поддержку AVX-512. В качестве примера были использованы материнские платы ASUS ROG MAXIMUS Z690 HERO и MSI MEG Z690 UNIFY.
На первой материнской плате изначально был BIOS версии 0702 с поддержкой AVX-512. Для их активации требуется выключить энергоэффективные ядра, после чего инструкции включались автоматически. После обновления BIOS до версии 0811 ситуация не изменилась.
На второй материнской плате для включения AVX-512 необходимо выключить E-ядра и включить поддержку инструкций в BIOS. Если на версии BIOS 1.13 всё работало нормально, то на 1.21 уже ничего не работает и активировать инструкции попросту невозможно.
Также ресурс подтверждает, что на материнской плате MSI MAG B660M MORTAR WIFI DDR4 изначально отсутствует поддержка инструкций AVX-512. Возможно, всё дело в предустановленной версии BIOS, однако если в случае Z690 остался бесполезный переключатель для включения поддержки инструкций, то на B660 он отсутствует вовсе.
Недавно мы опубликовали новость о том, что Intel отключила поддержку набора инструкций AVX-512 на процессорах Alder Lake с новыми версиями BIOS. Ранее мы не могли проверить функцию в лаборатории, но теперь мы подтвердили ее на практике.
Официально настольные процессоры Alder Lake набор инструкций AVX-512 не поддерживают, что объясняется отсутствием валидации Intel. Но функциональные блоки в производительных ядрах есть, и отключение в BIOS эффективных ядер приводило к активации AVX-512. Мы проверили эту возможность в наших тестах новых процессоров. Ходит много слухов по поводу того, почему набор команд AVX-512 официально не поддерживается. Но, по крайней мере, его можно было активировать указанным способом.
Факт заключается в том, что до сегодняшнего дня набор инструкций AVX-512 можно было активировать. Мы использовали в тестах процессоров Alder Lake материнскую плату ASUS ROG Maximus Z690 Hero с версией BIOS 0702. После отключения в BIOS эффективных ядер, производительные ядра начинали поддерживать AVX-512. И в некоторых тестах Core i9-12900K показывал преимущества от поддержки AVX-512. Мы также проверили материнскую плату MSI Z690 Unify, на которой с версией BIOS 1.13 тоже получилось включить AVX-512. Для этого в пункте «Advanced CPU Configuration» следовало выключить через «Per E-Core Control» все эффективные ядра. Затем в опциях разгона нужно было включить опцию «AVX-512 Support».
CPU-Z показывает наличие поддержки набора инструкций AVX-512:
Мы подготавливали платформу к тесту Core i5-12400, который получили сегодня, поэтому установили самую свежую версию BIOS 1.21, которая содержит те же самые функции. Мы отключили эффективные ядра и включили опцию AVX-512, но после загрузки поддержка набора инструкций AVX-512 исчезла:
Обновление BIOS содержит новую версию микрокода 18 вместо старой 15. Похоже, через микрокод Intel заблокировала активацию AVX-512. На материнской плате ASUS ROG Maximus Z690 способ активации AVX-512 оставался даже с последней версией BIOS 0811. Причем, как указывает ASUS, версия BIOS 0811 совместима со свей линейкой процессоров Alder Lake.
Мы поинтересовались у Intel, почему поддержка AVX-512 была отключена «задним числом». Однако пока не получили никакой официальной информации. На практике набор инструкций AVX-512 обычным пользователям вряд ли требуется, поскольку его поддерживают только профессиональные приложения. Но все равно несколько странно, зачем Intel потребовалось вносить подобную блокировку, тем более процессоры Alder Lake работали с AVX-512 вполне успешно.
Новый BIOS также заблокировал множитель на планке x51 при использовании AVX2. Процессор просто не выставляет более высокие тактовые частоты. И обойти блокировку через BIOS невозможно.

Включить AVX-512 на B660 невозможно вообще
В ходе тестирования материнской платы MSI MAG B660M MORTAR WIFI DDR4 мы попытались активировать AVX-512. Однако опций в BIOS для отключения эффективных ядер и активации AVX-512 просто не было. Можно было отключать одиночные ядра, но одно всегда оставалось активным. То есть включить поддержку AVX-512 не представляется возможным, по крайней мере, для ранее вышедших процессоров Alder Lake с эффективными ядрами. Будет интересно посмотреть, как все изменится ситуация в случае процессоров без ядер E.
Обновление: ASUS со следующим обновлением тоже уберет поддержку
Мы получили ответ от ASUS, на чьих материнских платах мы как раз успешно активировали AVX-512. Соответственно, версия BIOS 0811 все еще поддерживает AVX-512. Но следующие версии BIOS лишатся поддержки AVX-512 из-за нового микрокода процессоров Core 12-го поколения. Материнские платы на чипсетах H670, B660 и H610 изначально поставляются без поддержки AVX-512.
Обновление: ASUS отключает, MSI возвращает AVX-512
Через несколько недель мы вновь возвращаемся к теме AVX-512. Как мы и опасались, ASUS с версии BIOS 1003 установила новый микрокод Intel, поэтому активация функции AVX-512 в BIOS и отключение эффективных ядер не помогает. Набор инструкций AVX-512 больше на нашей материнской плате ASUS ROG Maximus Z690 Hero не работает.
Но MSI схитрила и добавила в версию BIOS A22 новый переключатель, который был протестирован на MEG Z690 Unify-X. Переключатель «AVX-512 Trial» активирует старый микрокод, инструкции AVX-512 вновь работают.
Производители материнских плат, а именно MSI в данном случае, продолжают искать способы обойти блокировку AVX-512. Пока неизвестно, будет ли похожая реализация от ASUS. По поводу материнских плат других производителей информации у нас нет.
Еще одна «фича», которую Intel вряд ли хотела получить в таком виде, касается разгона процессоров не-К поколения Alder Lake через базовую частоту. Мы успешно разогнали Core i5-12400 на материнской плате Z690, а также на модели B660 (тоже от ASUS), затем мы разогнали Core i3-12100F.
