Kwimuka kwa data center kuri DDR5 birashobora kuba ingenzi kurenza izindi kuzamura.Ariko, abantu benshi batekereza gusa ko DDR5 ari inzibacyuho yo gusimbuza DDR4 rwose.Abatunganya byanze bikunze bahinduka hamwe no kuza kwa DDR5, kandi bazagira udushyakwibukaImigaragarire, nkuko byari bimeze kubisekuruza byabanjirije kuzamura DRAM kuva SDRAM kugezaDDR4.
Ariko, DDR5 ntabwo ihinduka ryimbere gusa, irahindura imyumvire ya sisitemu yo kwibuka.Mubyukuri, impinduka kuri DDR5 zirashobora kuba zihagije kugirango zemeze kuzamura urwego ruhuza seriveri.
Kuki uhitamo uburyo bushya bwo kwibuka?
Ibibazo bya mudasobwa byarushijeho kuba ingorabahizi kuva mudasobwa yatangira, kandi iri terambere byanze bikunze ryateje ubwihindurize muburyo bwimibare myinshi ya seriveri, kwiyongera kwububiko nubushobozi bwo kubika, hamwe nisaha yo hejuru yisaha yihuta hamwe numubare wibanze, ariko kandi itera impinduka zububiko. , harimo no kwemeza vuba aha tekiniki ya AI idashyizwe hamwe kandi yashyizwe mubikorwa.
Bamwe bashobora gutekereza ko ibyo byose bibaho murwego rumwe kuko imibare yose izamuka.Nyamara, mugihe umubare wibikorwa bya cores wiyongereye, umurongo wa DDR ntiwakomeje umuvuduko, bityo umurongo wa buri rugingo wagabanutse mubyukuri.
Kuva amakuru yagiye yiyongera, cyane cyane kuri HPC, imikino, code ya videwo, gutekereza kumashini, gutekereza cyane, no gusesengura amakuru, nubwo umurongo mugari wohererezanya kwibuka ushobora kunozwa wongeyeho imiyoboro myinshi yo kwibuka muri CPU, Ariko ibi bitwara imbaraga nyinshi .Gutunganya pin kubara nabyo bigabanya kuramba kwubu buryo, kandi umubare wimiyoboro ntushobora kwiyongera ubuziraherezo.
Porogaramu zimwe, cyane cyane-sisitemu yo hejuru cyane nka GPUs hamwe na AI yihariye itunganya AI, koresha ubwoko bwibikoresho byinshi byo kwibuka (HBM).Ikoranabuhanga rikoresha amakuru kuva chip ya DRAM yegeranye kugeza kuri processor ikoresheje inzira ya 1024-bit yo kwibuka, bigatuma iba igisubizo cyiza kubikorwa byibanda cyane nka AI.Muri iyi porogaramu, gutunganya no kwibuka bigomba kuba hafi bishoboka kugirango bitange byihuse.Ariko, nayo ihenze cyane, kandi chip ntishobora guhura na modules zisimburwa / zishobora kuzamurwa.
Kandi DDR5 yibuka, yatangiye gukwirakwira cyane muri uyumwaka, yashizweho kugirango itezimbere umuyoboro mugari hagati ya processor na memoire, mugihe ikomeje gushyigikira kuzamura.
Umuyoboro mugari n'ubukererwe
Igipimo cyo kohereza DDR5 cyihuta kuruta icy'ibihe byose byabanjirije DDR, mubyukuri, ugereranije na DDR4, igipimo cyo kohereza DDR5 kirenze kabiri.DDR5 itangiza kandi inyubako zinyuranye zubaka kugirango zishoboze gukora kuri ibi biciro byoherejwe hejuru yinyungu zoroshye kandi bizamura imikorere ya bisi igaragara neza.
Byongeye kandi, uburebure bwaturika bwikubye kabiri kuva kuri BL8 kugeza kuri BL16, bituma buri module igira imiyoboro ibiri yigenga kandi byikuba kabiri imiyoboro iboneka muri sisitemu.Ntabwo ubona gusa umuvuduko mwinshi wo kwimura, ariko urabona kandi umuyoboro wibukwa wubatswe urusha DDR4 nubwo nta giciro cyoherejwe cyo hejuru.
Ibikorwa byibukwa cyane bizabona imbaraga nini kuva muri DDR5, kandi byinshi mubikorwa byakazi byibanda kumurimo, cyane cyane AI, ububikoshingiro, hamwe no gutunganya ibicuruzwa kumurongo (OLTP), bihuye nibi bisobanuro.
Igipimo cyo kwanduza nacyo ni ingenzi cyane.Umuvuduko uriho wa DDR5 yibuka ni 4800 ~ 6400MT / s.Mugihe ikoranabuhanga rimaze gukura, igipimo cyo kohereza giteganijwe kuba kinini.
Gukoresha ingufu
DDR5 ikoresha voltage yo hasi kurenza DDR4, ni ukuvuga 1.1V aho gukoresha 1.2V.Mugihe itandukaniro rya 8% rishobora kutumvikana nkinshi, itandukaniro rigaragara mugihe baringaniye kugirango babare igipimo cyo gukoresha amashanyarazi, ni ukuvuga 1.1² / 1.2² = 85%, bivuze ko uzigama 15% kumafaranga yishyurwa.
Impinduka zubwubatsi zatangijwe na DDR5 zorohereza umurongo mugari hamwe nigipimo cyinshi cyo kwimura, nyamara, iyo mibare iragoye kuyigereranya utabanje gupima neza aho ikoreshwa ryikoranabuhanga rikoreshwa.Ariko rero na none, kubera ubwubatsi bwubatswe hamwe nigipimo kinini cyo kohereza, umukoresha wa nyuma azabona iterambere ryingufu kuri biti yamakuru.
Mubyongeyeho, module ya DIMM irashobora kandi guhindura voltage yonyine, ishobora kugabanya ibikenewe kugirango hahindurwe amashanyarazi yumubyeyi, bityo bitange izindi ngaruka zo kuzigama ingufu.
Kubigo byamakuru, ni imbaraga zingana iki seriveri ikoresha nigiciro cyo gukonjesha giteye impungenge, kandi mugihe ibyo bintu bisuzumwe, DDR5 nkuburyo bukoresha ingufu nyinshi birashobora rwose kuba impamvu yo kuzamura.
Gukosora amakosa
DDR5 ikubiyemo kandi amakosa yo gukosora amakosa kuri chip, kandi mugihe inzira ya DRAM ikomeje kugabanuka, abakoresha benshi bahangayikishijwe no kongera igipimo cyamakosa ya biti hamwe nuburinganire bwamakuru muri rusange.
Kuri seriveri ya porogaramu, kuri-chip ECC ikosora amakosa ya biti imwe mugihe cyo gusoma amategeko mbere yo gusohora amakuru kuva DDR5.Ibi bikuramo imitwaro imwe ya ECC kuva sisitemu yo gukosora algorithm kuri DRAM kugirango igabanye umutwaro kuri sisitemu.
DDR5 itangiza kandi kugenzura amakosa no gukora isuku, kandi nibishoboka, ibikoresho bya DRAM bizasoma amakuru yimbere kandi byandike amakuru yakosowe.
Vuga muri make
Mugihe isura ya DRAM mubusanzwe atariyo ngingo yambere ikigo cyitaweho mugihe cyo gushyira mubikorwa kuzamura, DDR5 ikwiye kurebwa neza, kuko ikoranabuhanga risezeranya kuzigama ingufu mugihe uzamura imikorere cyane.
DDR5 ni tekinoroji ishoboza ifasha abayitangiye hakiri kare kwimuka neza kubihimbano, byapimwe byamakuru yigihe kizaza.Abayobozi ba IT n'abashoramari bagomba gusuzuma DDR5 bakamenya uburyo nigihe cyo kwimuka bava DDR4 bakajya DDR5 kugirango barangize gahunda zabo zo guhindura amakuru.
