GDDR5 - layo eli ikhadi levidiyo? Isizukulwana yesihlanu DDR SDRAM memory

Abo bokuqala bagqiba ukuba kunye nePC yakho, okanye ukuba ukuqonda oko ngaphakathi, qala ngobuso a lot of amagama impenduka. Xa uvula i-inshorensi computer, sibona ezininzi iingcingo, iipleyiti, fans, olubi ubushushu, njl Ukuze uphephe ebangela kwakhona umninindlu ukuba ukuqhagamshelana abahlobo, lula ukuyiqonda.

Namhlanje siya sithethe ingcamango umdla enjalo, njengoko GDDR5. Oko kukuthi, abaninzi andazi, abanye angazenza ezinye zinolwazi nokuqonda. Ukuze ukuba ukubhidanisa umfundi, kuyimfuneko ukuba athi kwaoko ukuba GDDR5 - inkumbulo. Kutheni yeyethu kwaye apho akhoyo, siza ukwazi ngakumbi.

video memory

Ukuba alahle kumntu ningazi kanye neqela amagama, kubhetele ukuba ahambe kwelinye icala. Sonke siyazi malunga motherboard, nto leyo ibekwa kwimeko PC. Iya kuqhagamshelwa iprosesa, umbane, ikhadi levidiyo, RAM kunye nezinye izinto. Ngaphandle nje kokuba kukho inkumbulo inkqubo, naye abe efanayo, kwaye ikhadi levidiyo.

Ngenxa yoko, kukho ibinzana elithi - memory umboniso. Enyanisweni, iyafana naleyo RAM, kodwa inoxanduva ncakasana ukugcinwa elo inxalenye ingcaciso eyimfuneko ukuze ivelise kwakhona umfanekiso kwiskrini. Mu kuya kwa nshita imemori kwenkqubo yonke, oko ijongene kuphela kalukhuni zevidiyo. Ngoko ke, i chips ividiyo memory zibekwe kwikhadi yemizobo.

ekuqaleni

Qala kunye nengenelo yam kwamhla RAM ezahlukeneyo kuyimfuneko kunye ukuguqulwa yokuqala. Ifom endala "RAM" kucingelwa ukuba imemori ye DDR. Ngoku, mhlawumbi, akunakwenzeka ukufumana motherboard ngale hlobo. ombane zokusebenza waba 2.5 volts. Kakade ke, ejonga zonke iintlobo sele, sinako ngokukhuselekileyo bathi imemori DDR osetyenzisiweyo umbane kakhulu.

uhlobo

Ngaphambi kokuba sifunde ngoko na kwi GDDR5 ikhadi yemizobo, kufuneka ukuqonda iyantlukwano. Iintlobo memory for lonke ixesha, kwaba abaninzi. Chaza ngalinye akwenzi ngqiqo, ngoko kufuneka uye ngqo ingongoma.

Ngokubanzi, kukho imemori yofikelelo oluzenzekelayo DRAM got igama. Kuqala yaba ezaziwayo lihlabathi ngexesha Second World War. Kodwa ukubonakaliswa kwayo mihla kwabonakala ngo-1966. ababhekisi phambili ixesha elide kunye nabavelisi sazama ukuphucula memory. Enye lweentlobo yokuqala waba PM DRAM ngasekuqaleni-imi- 90 kwinkulungwane yokugqibela.

Kodwa ababhekisi phambili yonke ixesha ukunyusa isantya nomthamo "RAM". DDR SDRAM - Emva amalinge ezintandathu, uhlobo olutsha livela emalikeni. Waba ezahlukileyo iinguqulelo ezidlulileyo ephuculweyo Data Rate (kabini). Olu hlobo ke kuqala efakiweyo amakhadi imizobo. Ekuhambeni kwexesha, ababhekisi wagqiba ukusebenzisa RAM kunye chipset.

isisekelo

Kukholelwa ukuba GDDR5 iye wabonakala ngenxa DDR SDRAM. Le nguqulelo sesihlanu leyo aveliswe isicelo. Ezi softs zifuna ekwiqondo eliphezulu. Owandulela olu khetho liye laba yesine-isizukulwana memory. Zombini zisekelwe DDR3. Ijelo lonxibelelwano iye kabini, kukho ezingqubano ububanzi ziikhowudi 8.

Okubangel 'umdla kukuba olu hlobo lomsebenzi kwi eninzi abenzi. Ngoko ke uphando "isangqa" kwakukho Hynix, Qimonda, Samsung kunye JEDEC. Ukumangala into yokuba ukusebenza kunye nabo kunye nenkampani AMD. Kwathabatha ixesha elide kakhulu, yaye ukususela ekuqaleni ukuya zokuyigqiba kwathatha iminyaka emithathu. Ngeli xesha ababhekisi bakwazi ukuba bazuze iziphumo ezisemagqabini.

Emva koko sifunda okuninzi malunga GDDR5, yintoni na yaye oko. Kodwa asinguye wonke umntu unako ukusebenzisa eli khadi njengoko specs yayo nangoku bokwakha. Ukususela ekuqaleni chips yayo indlela esebenza ombane aphantsi 1.5 V, kwaye lexinene yaba 0.5-2 GB. esasidla awo 4000 MHz, yaye emva kwexesha elithile ikwazile ukunyusa eli nani ukuya ku 7000 MHz.

Yena sele Wabonakala ukuba ukuxinana 1 Gbit chip ngo-2009, emva konyaka - noxinano of Gbps-2. Le ndlela yokugqibela iye yasekwa yinkqubo-NM 50 technology. Ngu ekuqaleni kuka-2015 i-phuhliso kwaba nemiphumo emihle. chip mninzi bafikelela Gbps 8, kunye nenkqubo kungamampunge ndaqeshwa 20 NM. Le umphathi werekhodi weza phantsi kwesikhokelo inkampani Korean Samsung.

incazelo

Ukuze ufunde okungakumbi malunga of GDDR5, ukuba le nto kufuneka ukuba le inkumbulo, kubalulekile ukuba siqwalasele iimpawu ezingundoqo, ezisetyenziswa ngoku ngabo bonke abenzi. Njengokuba kuye kwacaca xa kwisihloko unobumba «G» inoxanduva ingqikelelo Graphics. Oko kukuthi, olu hlobo inkumbulo efunekayo ukuze ikhadi levidiyo.

GDDR5 ukhululwe phantsi emgangathweni. Phantsi kolwalathiso izakhiwo 8n, kunye uqwalaselo zojongano nemiba, kwakunye nobugcisa ephucula intsebenzo. Enye chip uba ububanzi ziikhowudi 32 umzimba waba 170 abafow. technology nkqubo NM 40.

Le rhoqo nga imiselwe parameters ezimbini. Ukuba lokuqala libonisa ixabiso 1250 MHz, le yesibini iya kulingana-2500 MHz, okt ngokuphindwe kabini. Abavelisi badla abonisa ezitsho ezahlukeneyo, kodwa kusoloko isantya transfer iyafana.

Inzuzo ephambili imikhwa ibe sokuphucula igalelo. Mu kuya kwa nshita isizukulwana yesithathu video, ekugqibeleni yesihlanu ebhasini bit nobubanzi 128/256. Ngeendlela ezininzi wanceda ezinye indicators. Ngenxa yoko, i-512 bit GDDR3 esetyenziselwa amavili. Le ubungakanani nani lanyuka chip, ukupakishwa wayo, kwaye ngaloo ndlela ke iindleko imodeli yonke. Video ikhadi nale hlobo osetyenzisiweyo kwaye imali kakhulu amandla.

ukuqaliswa

Ngoku siyazi ka GDDR5, oko kukuthi ividiyo inkumbulo, umsebenzi labavelisi phambili. Akumangalisi ke, imodeli yokuqala ikhadi ividiyo ibonakele ngo-2008, ivela, AMD. Waba ATI Radeon HD 4870. Yayichazwa kwiinguqulelo ezimbini, nto leyo eyahlukileyo umthamo we-512 MB kunye 1 GB.

Kwakukho imizekelo Nvidia Geforce. GDDR5 uya kubonakala kwangoko kuthotho amakhadi, phakathi ezo :. GTX 550, lo GTX 560, lo GTX 580, lo GTX 590, lo GTX 660, lo GTX 680, njl Ukongeza, olu hlobo memory lufumaneka ngoku kwinguqulelo yesine PlayStation console. Ngelo xesha yabekwa apho njengendawo RAM.

iziphumo

Ukushwankathela konke oku kungasentla, kubalulekile ukuqonda ukuba ixesha sele idlule RAM ukususela wabonakala. imemori vidiyo zazivelela ndakubumba. Ngoku isizukulwana sesihlanu akazange abe kwisantya ezininzi bonke. Kakhulu kutshanje waziwa olunye uhlobo - GDDR5X. Yena kabini ngokukhawuleza. Kunjalo, lo ngowona GDDR5 memory kakhulu ngenkani, kungekuphela nje njengenxalenye ikhadi levidiyo, kodwa nje chips RAM eyahlukileyo.

Ngoku ke ngozi oluphambili, nto leyo negalelo yokuduka olu hlobo lwe memory kunye imarike kukuba imemori akanayo enye ukuphuhlisa nokuphucula. Ukongeza, ngoko kude ke abazange bakwazi ukusombulula le ngxaki kunye ukusetyenziswa kwamandla eliphezulu. Nangona amanani asuka iinguqulelo ezidlulileyo zincinane, kodwa nto ayithethi ukuyisombulula. Ngaphezu koko, banikwa lo mkhwa kutshanje malunga overclocking, ingxaki ngesifo amandla eliphezulu ezingxamisekileyo kunye supercedes.
