GDDR5 - kungcono ekhadini isiqophi? Isizukulwane yesihlanu memory DDR SDRAM

Labo bokuqala banquma ukubeka ndawonye PC yakho, noma ukuqonda ke ngaphakathi, qala nobuso eziningi ngokuya iyadida. Lapho sithulula ikhava ikhompyutha, sibona eziningi izintambo, amapuleti, abalandeli, ukushisa nokucwila, njll Ukuze kugwenywe ukucunula waphinda master hhayi ukuxhumana nabangane, kulula ukuqonda.

Namuhla sizoxoxa umqondo ezithakazelisa kangaka, njengoba GDDR5. Lokho, abaningi abazi, abanye bangase bacabange ezinye unolwazi futhi baqonde. Ukuze ukudida umfundi, kubalulekile ukusho ngesikhathi esisodwa ukuthi GDDR5 - kuyinto inkumbulo. Kungani kungokwalabo futhi ukuphi, sizobe ukwazi kabanzi.

inkumbulo Isiqophi

Hhayi ukuthi alahle nomuntu abangenalwazi kanye kweqembu imigomo, kungcono ukuya nge Ngakolunye uhlangothi. Sonke siyazi mayelana umbadlana, okuyinto ibekwa icala PC. Shall uxhumeke wokugaya, ugesi, isiqophi ikhadi, RAM nezinye izakhi. Ngaphandle kweqiniso lokuthi kukhona inkumbulo kohlelo, Ubuye umqondo ofanayo, futhi leso ikhadi vidiyo.

Ngakho, kukhona elithi - inkumbulo vidiyo. Empeleni, kuba sengathi iyafana ukuthi we-RAM, kodwa unesibopho ngqo isitoreji ukuthi ingxenye ulwazi oludingekayo ekukhiqizweni isithombe esikrinini. Ngokungafani inkumbulo lonke uhlelo, kumane wemfanelo cishe yevidiyo. Ngakho-ke, i-chips inkumbulo isiqophi ezibekwe ekhadini ihluzo.

ekuqaleni

Qala yabangane benu nge RAM ezahlukene kuyadingeka nge ukwehlukahlukana kuqala. Ifomu endala ka "RAM" ubhekwa inkumbulo DDR. Manje, mhlawumbe, akunakwenzeka ukuthola umbadlana nale hlobo. Operating voltage kwaba 2.5 volts. Yiqiniso, abheke emuva zonke izinhlobo kakade, singasho ngokuphepha ukuthi imemori DDR waqothula ugesi kakhulu.

zinhlobo

Ngaphambi kokuba sithole ukuthi ngalokho ivuliwe GDDR5 ihluzo ikhadi, kubalulekile ukuqonda ukwehluka. Izinhlobo inkumbulo kuze kube phakade, kwaba ezingenakubalwa. Yibhale phansi ngayinye akwenzi mqondo, ngakho kufanele ukuya ngokuqondile iphuzu.

Ngokuvamile, uHlelo Lwesiqondisi Kungena Esilula dram ithole igama. It kuqala laziwa emhlabeni ngesikhathi seMpi yoMhlaba yesiBili. Kodwa ukubonakaliswa walo wanamuhla lalibukeka ngayo 1966. Long isikhathi abathuthukisi kanye abakhiqizi bazama ukuthuthukisa inkumbulo. Omunye izinhlobo lokuqala baba PM dram ngasekuqaleni 90-yalolucwaningo kwekhulu elidlule.

Kodwa onjiniyela kwadingeka sonke isikhathi ukwandisa isivinini kanye ivolumu "RAM". DDR SDRAM - Emva kwemizamo eziyisithupha, uhlobo olusha luvela emakethe. Waba sihluke izinguqulo ezandulele Enhanced Idatha Ukukala (kabili). Lolu hlobo is kuqala ukufakwa ihluzo amakhadi. Ngokuhamba kwesikhathi, onjiniyela wanquma ukusebenzisa RAM chipset.

isisekelo

Kukholakala ukuthi GDDR5 ubonakele sibonga DDR SDRAM. Le nguqulo wesihlanu okuyinto kwaba eyenziwe isicelo. Lezi Softs zidinga komkhawulokudonsa okusezingeni eliphezulu. Owandulela lolu khetho isibe inkumbulo oyisizukulwane sesine. Bobabili zisekelwe DDR3. Isiteshi zokuxhumana isibe kabili, kukhona Buffers ububanzi 8 izingcezu.

Kuyathakazelisa ukuthi lolu hlobo umsebenzi omningi abakhiqizi. Ngakho ucwaningo "Umbuthano" babe Hynix, Qimonda, Samsung futhi JEDEC. The isimanga nakakhulu yiqiniso lokuthi isebenza nabo futhi inkampani AMD. Kwathatha isikhathi eside kakhulu, futhi kusukela ekuqaleni kuze uqede kwathatha iminyaka emithathu. Ngesikhatsi kulandzelwa lendlela, onjiniyela bakwazi ukufeza imiphumela emihle kakhulu.

Khona-ke sifunda okuningi GDDR5, ukuthi kuyini nokuthi lokho. Kodwa akubona bonke abantu zingase zisebenzise lokhu inkumbulo njengoba specs zalo namanje obumba. Kusukela ekuqaleni endleleni yayo chips elalakha voltage low 1.5 V, kanye kwabantu kwaba 0.5-2 GB. imvamisa yabo ifinyelela 4000 MHz, futhi ngemva kwesikhathi esithile ephethwe ukukhulisa lesi sibalo kuze kube 7000 MHz.

Uvele usezibophezele wavela kwabantu of 1 Gbit chip 2009, ngemva konyaka - at kwabantu of 2 Gbps. Inketho yokugcina sesakhiwe ngo-50-nm inqubo ubuchwepheshe. Ngasekuqaleni kuka-2015 ukuthuthukisa iholele emiphumeleni emihle kakhulu. chip ukuminyana safinyelela 8 Gbps, kanye nenqubo bumbela wayeqashwe for 20 NM. Lokhu umnikazi irekhodi wafika ngaphansi kobuholi inkampani Korean Samsung.

sebhithi

Ukuze ufunde kabanzi mayelana ka GDDR5, yingakho sidinga lokhu inkumbulo, kubalulekile ukuba sicabangele izici eziyisisekelo, okuyinto manje esetshenziswa zonke abakhiqizi. Njengoba siye saba sobala e isihloko incwadi «G» unesibopho nomqondo Graphics. Okungukuthi, lolu hlobo inkumbulo luyadingeka ikhadi vidiyo.

GDDR5 Isikhishwe ngaphansi Standardization. Ngaphansi kokuqondisa kweNdikimba izakhiwo 8n, nge ukucushwa kwe-Dynamics esibonakalayo, kanye nobuchwepheshe ukuthi ithuthukise ukusebenza. Omunye chip has a ububanzi 32 izingcezu kanye umzimba kwadingeka 170 oxhumana. Inqubo ubuchwepheshe 40 NM.

Imvamisa kungenziwa kunqunywa amapharamitha amabili. Uma kuqala kubonisa ukubaluleka 1250 MHz, kwesibili kuyoba ulingana 2500 MHz, okungukuthi ngaphambi kabili njengoba khulu. Abakhiqizi ngokuvamile abonisa amaza ezahlukene, kodwa izinga ukudluliswa ihlale ifana.

Inzuzo enkulu Amathrendi bekulokhu ukuthuthukisa throughput. Ngokungafani isizukulwane sesithathu ividiyo, ebaleka sesihlanu saba ububanzi ibhasi kancane 128/256. Ngezindlela eziningi kwasiza ngisindise abathile izinkomba. Ngakho, i-GDDR3 512 bit esetshenziselwa amathayi. Lesi sibalo anda ubukhulu chip, kwikhava yawo, futhi ngaleyo ndlela izindleko lonke imodeli. ikhadi levidiyo no lolu hlobo idliwe imali enkulu namandla.

ukwethulwa

Manje siyazi ka GDDR5, okungukuthi inkumbulo ividiyo, umsebenzi abakhiqizi eziholela. Akumangalisi ukuthi imodeli lokuqala ikhadi isiqophi uvele 2008, kuvela, AMD. Waba ATI Radeon HD 4870. Lokhu kwethulwa ezinguqulweni ezimbili, okuyinto kwahluka ivolumu 512 MB futhi-1 GB.

Kwakukhona amamodeli we Nvidia Geforce. GDDR5 ngeke ngokushesha avele uchungechunge amakhadi, phakathi eyayibonakala :. GTX 550, le GTX 560, le GTX 580, le GTX 590, le GTX 660, le GTX 680, njll Ngaphezu kwalokho, lolu hlobo inkumbulo manje okutholakala ku-version wesine PlayStation console. Ngesikhathi esifanayo yafakwa njengeziphakamiso RAM.

okutholakele

Kufinyeta bonke ngenhla, kubalulekile ukuqaphela ukuthi isikhathi esiningi isidlulile RAM kusukela yavela. inkumbulo Isiqophi uye savela futhi kwakhiwa. Manje isizukulwane lesihlanu azange abe ijubane kakhulu kubo bonke. Esanda kutholakala baba olunye uhlobo eyaziwa - GDDR5X. He is kabili njengoba fast. Noma kunjalo, i-yafuna kakhulu GDDR5 inkumbulo, hhayi kuphela njengoMhlengi ingxenye ikhadi vidiyo, kodwa futhi njengendlela ehlukene RAM chips.

Manje usongo main, okuyinto kungase kube nomthelela ukunyamalala lolu hlobo ngohlelo emakethe ukuthi imemori has kwenye ukuthuthukisa nokwenza ngcono. Ngaphezu kwalokho, kuze kube manje abazange ephethwe ukuxazulula inkinga nge high energy ukusetshenziswa. Nakuba amanani asuka izinguqulo ezandulele mancane kakhulu, kodwa lutho awusebenzi ukuxazulula. Ngaphezu kwalokho, unikezwa mkhuba yamuva maqondana Overclocking, inkinga ngamandla okusezingeni eliphezulu ukusetshenziswa esiphuthumayo futhi supercedes.
