Ingabe Isizukulwane Samuva se-PC Memory Impact PC siyoba kakhulu?
Imemori ye-DDR3 isetshenziswe emhlabeni wePC iminyaka eminingi manje. Eqinisweni, kubonakala sengathi yiwona omude kunazo zonke izindinganiso zokukhumbula amanani wedatha kuze kube yimanje. Lokhu kuye kwaba yintandokazi kubathengi ngoba kuye kwasho izintengo zememori ezingabizi kakhulu kodwa futhi kusho iminyaka embalwa edlule ukuthi amakhompyutha ethu aye avinjelwe ijubane lememori. Lokhu kubonakala ngokucacile njengoba siqala ukwenza imisebenzi enzima kakhulu efana nokuhlela ividiyo yedeskithophu futhi usebenzisa isitoreji esisheshayo njengamashayela wombuso oqinile .
Ngokukhululwa kwe-chipset ye-Intel X99 ne-Haswell-E nabaprosesa be-6th Generation Intel Core, i-DDR4 manje isezingeni elijwayelekile lokusetshenziswa kumakhompyutha abo. Izindinganiso zaqalwa emuva ngo-2012 kodwa sekuyiminyaka eminingana ukuthi lezo zindinganiso zigcine zenze imakethe. Ngakho ake sithole ukuthi yiziphi izinguquko lezinga lememori elisha elizolethela ku-PC.
Imishini esheshayo
Njengoba nje ngokusungulwa kwamazinga e-DDR3, i-DDR4 ngokuyinhloko ikwazi ukubhekana nesivinini esheshayo. Ngokungafani nokuguqulwa kwe-DDR2 kuya ku-DDR3, ukuhamba kwejubane kuzoba okunye ngoba sekuthathe isikhathi eside ukuthi i-DDR4 yamukeleke embonini. Imemori ejwayelekile ye-JDEC ejwayelekile ye-DDR3 manje isebenza ngo-1600MHz. Ngokuphambene, imemori entsha ye-DDR4 iqala ngo-2133MHz okukhulisa isivinini se-33%. Ngokuqinisekile, kunememori ye-DDR3 etholakala ngokusheshisa phezulu kuka-3000MHz kodwa lokhu kunememori engaphezu kwesikhashana ehamba phambili ejwayelekile kanye nezidingo zamandla aphakeme kakhulu. Izindinganiso ze-JDEC ze-DDR4 zibuye zichaze kuze kube yijubane le-3200MHz eliphindwe kabili umkhawulo wamanje we-DDR3 1600MHz.
Njengokunye ukuqhuma kwezizukulwane, ukukhula okukhulayo kusho nokunyuka kwama-latencies. I-latency ibhekisela ukuthi kuthatha isikhathi esingakanani ukuthatha umlawuli wememori ukuze uthathe ngokuyisisekelo umyalo wokufinyelela imemori futhi empeleni ufunde noma ubhale kumamojuli amemori. Ngokusheshisa kunememori, imijikelezo eningi ithambekele ukuthatha isilawuli ukuyihlola. Le nto ihamba ngesivinini sewashi ephakeme, ukuvama kokwandisa ngokuvamile akuthinti ukusebenza jikelele ngenxa yendlela yokukhuphuka yokukhulumisana kwedatha kwimemori ku-CPU.
Ukusetshenziswa Kwamandla Amandla
Amandla amakhompiyutha adla kuyinkinga enkulu ikakhulu uma ubheka imakethe yekhompyutha yeselula. Amandla angaphansi aphelile, isikhathi eside idivayisi ingasebenza kumabhethri. Njengesizukulwane ngasinye sememori ye-DDR, i-DDR4 iphinda inciphise inani lamandla adingekayo ukusebenza. Kule nkathi, amazinga we-voltage asehlile ukusuka ku-1.5 volts kuya ku-1.2 volts. Lokhu kungase kungabonakali njengokuningi kepha kungenza umehluko omkhulu nge-laptop systems. Njenge-DDR3, i-DDR4 cishe izothola izinga eliphansi le-voltage elivumela ngisho nezidingo zamandla aphansi kulawo mahlelo ahloselwe ukusebenzisa lolu hlobo lokukhumbula.
Ngingayithuthukisa i-PC yami kumemori we-DDR4?
Emuva ekushintsheni kusuka kwimemori ye-DDR2 kuya kwe-DDR3, ubuciko be- CPU ne-chipset buhlukile kakhulu. Lokhu kwakusho ukuthi amanye amabhodi wamabhodi kusukela ngaleso sikhathi ayenamandla okusebenzisa i-DDR2 noma i-DDR3 ku-motherboard efanayo. Lokhu kukuvumele ukuthi uthole uhlelo lwekhompuyutha yedeskithophu nge-DDR2 engabizi futhi bese uthuthukisa imemori ku-DDR3 ngaphandle kokufaka esikhundleni se-motherboard noma i-CPU. Lezi zinsuku, abalawuli bezinkumbulo bakhiwe ku-CPU. Ngenxa yalokho, ngeke kube khona ihadiwe lokuguquguquka elingasebenzisa kokubili i-DDR3 ne-DDR4 entsha. Uma ufuna ukuba nekhompyutha esebenzisa i-DDR4, kuzodingeka uthuthukise wonke amasistimu noma okungenani i- motherboard , i-CPU nenkumbulo.
Ukuze uqinisekise ukuthi abantu abazami ukusebenzisa inkumbulo ye-DDR4 ngamahlelo asekelwe e-DDR3, iphakheji elisha le-DIMM laklanyelwe. Ziyizilinganiso ezifanayo namamodeli adlule we-DDR3 kodwa inenani eliphakeme lezikhonkwane. I-DDR4 manje isebenzisa izikhonkwane ezingu-288 uma kuqhathaniswa nezikhonkwane ezingu-240 zangaphambilini okungenani kuma-desktop systems. Amakhompyutha we-laptop azobhekana nesayizi efanayo kodwa nge-260-pin SO-DIMM layout kuqhathaniswa nomklamo we-204-pin we-DDR3. Ngaphandle kwesakhiwo sephini, inothi yamamojula ayoba endaweni ehlukile ukuvimbela amamojula ukuba afakwe kwi-slots eyenziwe nge-DDR3.
