Sabbin bayanai akan Intel Lakefield XNUMX-core hybrid processors

• A nan gaba, kusan dukkanin samfuran Intel za su yi amfani da shimfidar wuri na Foveros, kuma aiwatar da aiwatar da shi zai fara a cikin fasahar aiwatar da 10nm.
• Za a yi amfani da ƙarni na biyu na Foveros ta farkon 7nm Intel GPUs waɗanda za su sami aikace-aikacen a sashin uwar garken.
• A wani taron masu saka hannun jari, Intel ya bayyana waɗanne matakai biyar na injin Lakefield zai ƙunshi.
• A karon farko, an buga hasashen matakin aikin waɗannan na'urori masu sarrafawa.

A karon farko, Intel yayi magana game da ci-gaba na ƙirar Lakefield matasan masu sarrafawa. a farkon watan Janairu a wannan shekara, amma kamfanin ya yi amfani da taron na jiya don masu zuba jari don haɗa hanyoyin da aka yi amfani da su don ƙirƙirar waɗannan na'urori a cikin ma'anar ci gaban kamfani a cikin shekaru masu zuwa. Aƙalla, an ambaci shimfidar sararin samaniya na Foveros a taron jiya a cikin mahallin daban-daban - za a yi amfani da shi, alal misali, ta farkon alamar 7nm GPU mai hankali, wanda zai sami amfani a sashin sabar a cikin 2021.

Don tsarin 10nm, Intel za ta yi amfani da tsarin Foveros 7D na ƙarni na farko, yayin da samfuran 2021nm za su matsa zuwa tsarar Foveros na ƙarni na biyu. A shekara ta XNUMX, ƙari, EMIB substrate zai haɓaka zuwa ƙarni na uku, wanda Intel ya riga ya gwada akan kayan aikin sa na shirye-shirye da na'urori masu sarrafa wayar tafi-da-gidanka na Kaby Lake-G na musamman, yana haɗa nau'ikan ƙididdigar Intel tare da guntu mai hankali na AMD Radeon RX Vega M graphics. Saboda haka, tsarin da aka yi la'akari da tsarin Foveros na na'urorin wayar hannu na Lakefield da ke ƙasa ya samo asali ne tun ƙarni na farko.

Lakefield: biyar yadudduka na kammala

A taron ga masu zuba jari Daraktan Injiniya Venkata Renduchintala, wanda Intel ke ganin ya dace a kira da sunan barkwanci "Murthy" a cikin duk takaddun hukuma, ya yi magana game da manyan matakan shimfidawa na masu sarrafa Lakefield na gaba, wanda ya ba da damar fadada fahimtar irin waɗannan samfuran idan aka kwatanta da Janairu. gabatarwa .

Duk fakitin na'ura mai sarrafa Lakefield yana da girman 12 x 12 x 1 mm gabaɗaya, wanda ke ba ku damar ƙirƙirar ƙananan uwayen uwa waɗanda suka dace da jeri ba kawai a cikin kwamfyutocin bakin ciki ba, allunan da na'urori masu canzawa daban-daban, har ma a cikin manyan wayoyi masu inganci. .

Mataki na biyu shine bangaren tushe, wanda aka samar ta amfani da fasahar 22 nm. Yana haɗa abubuwa na tsarin dabaru na tsarin, 1 MB cache mataki na uku da tsarin tsarin wutar lantarki.

Layer na uku ya karbi sunan dukan ra'ayi na shimfidawa - Foveros. Matrix ne na haɗin haɗin gwiwar 2.5D mai daidaitacce wanda ke ba da damar musayar bayanai da kyau tsakanin matakan da yawa na kwakwalwan siliki. Idan aka kwatanta da ƙirar gadar silicon 3D, bandwidth na Foveros yana ƙaruwa sau biyu ko uku. Wannan ƙayyadaddun ƙayyadaddun ƙayyadaddun wutar lantarki yana da ƙananan ƙayyadaddun wutar lantarki, amma yana ba ku damar ƙirƙirar samfurori tare da matakan amfani da wutar lantarki daga 1 W zuwa XNUMX kW. Intel yayi alƙawarin cewa fasahar tana kan matakin balaga wanda matakin yawan amfanin ƙasa ya yi yawa sosai.

Matakin na huɗu ya ƙunshi abubuwan haɗin 10nm: ƙirar Atom na tattalin arziƙi huɗu tare da gine-ginen Tremont da babban cibiya tare da gine-ginen Sunny Cove, da kuma tsarin ƙirar tsararraki na Gen11 tare da manyan abubuwan kisa na 64, waɗanda masu sarrafa Lakefield za su raba tare da dangin 10nm na wayar hannu na Ice Lake. A kan wannan matakin akwai wasu abubuwan da ke inganta haɓakar zafin jiki na gabaɗayan tsarin matakan da yawa.

A ƙarshe, a saman wannan "sanwici" akwai kwakwalwan ƙwaƙwalwar ajiya na LPDDR4 guda huɗu waɗanda ke da ƙarfin 8 GB. Tsawon shigarwarsu daga tushe bai wuce millimita ɗaya ba, don haka duk "shelf" ya zama aikin buɗewa sosai, ba fiye da millimita biyu ba.

Bayanan farko akan tsari da wasu halaye lakefield

A cikin bayanan ƙafa zuwa sanarwar manema labarai na Mayu, Intel ya ambaci sakamakon kwatancen na'urar sarrafa yanayin Lakefield tare da na'ura mai sarrafa 14nm dual-core Amber Lake. Kwatancen ya dogara ne akan kwaikwaiyo da kwaikwaya, don haka ba za a iya cewa Intel ya riga ya sami samfuran injiniya na na'urorin sarrafa Lakefield ba. A watan Janairu, wakilan Intel sun bayyana cewa na'urori masu sarrafa Ice Lake 10nm ne za su fara shiga kasuwa. A yau ya zama sananne cewa isar da waɗannan na'urori masu sarrafawa don kwamfyutocin za su fara a watan Yuni, kuma akan nunin faifan nunin Lakefield shima yana cikin jerin samfuran a cikin 2019. Don haka, za mu iya dogaro da farkon farawar kwamfutocin hannu na tushen Lakefield kafin ƙarshen wannan shekara, amma rashin samfuran injiniya har zuwa Afrilu yana da ɗan ban tsoro.

Bari mu koma ga daidaitawar na'urori masu sarrafawa. Lakefield a wannan yanayin yana da muryoyi guda biyar ba tare da tallafin zare da yawa ba; sigar TDP na iya ɗaukar ƙima biyu: biyar ko bakwai watts, bi da bi. A cikin haɗin gwiwa tare da mai sarrafawa, ƙwaƙwalwar LPDDR4-4267 tare da jimlar ƙarfin 8 GB, wanda aka saita a cikin ƙirar tashoshi biyu (2 × 4 GB), yakamata yayi aiki. An wakilta na'urori masu sarrafa Amber Lake da ƙirar Core i7-8500Y tare da muryoyi biyu da Hyper-Threading tare da matakin TDP wanda bai wuce 5 W ba da mitoci na 3,6/4,2 GHz.

Idan kun yi imani da maganganun Intel, na'ura mai sarrafa Lakefield yana ba da, idan aka kwatanta da Amber Lake, raguwa a cikin yanki na uwa da rabi, rage yawan amfani da wutar lantarki a cikin jihar mai aiki da rabi, karuwa a aikin zane da kashi biyu, kuma raguwar amfani da wutar lantarki sau goma a cikin rashin aiki. An gudanar da kwatancen a cikin GfxBENCH da SYSmark 2014 SE, don haka baya yin kamar yana da haƙiƙa, amma ya isa ga gabatarwar.
