1, Chii chinonzi DDR?
DDR, Double Data Rate, tekinoroji ine simba isina kujairika yekuwana ndangariro (DRAM), iyo inomiririra kaviri data rate synchronous dynamic random access memory uye inovandudza mwero wekufambisa data zvichienzaniswa neyekare SDRAM (Single Data Rate). Kana iyo DDR yakaiswa pachigadzirwa ichinonoka kana kuti isina kukwana, mapurogiramu anodiwa haazokwanisi kushanda pamudziyo.
Muna 2000, DDR memory yakaburitswa. Mumakore gumi apfuura, maPC mazhinji anga achimhanyisa DDR4 ndangariro, uye ikozvino DDR5 iri kuita zvishoma nezvishoma chiyero chitsva chenguva ino.
Zvinogona kutaurwa kuti kudzokororwa kwega kwega kweDDR kwakavandudza kuita kana kuchienzaniswa neyakatangira, kubva pa2.7-3.2GB/s danho rekufambisa reDDR1, kuenda ku21GB/s yeDDR4, kusvika ku6.4Gbps yeDDR5, ichiwedzera zvakanyanya kukurumidza kugadzirisa data. Uye inopa mukana kune mamwe akaoma kunzwisisa komputa mabasa.
2, Chii chinonzi DDR5?
DDR5 ndiyo yechishanu iteration yeDDR, ine kaviri bandwidth uye kugona kweDDR4. Zvishandiso zvinogona kuita zvimwe zvinhu panguva imwe chete uye kazhinji zvine hunyanzvi komputa. Izvi zvinowedzeredzwa zvinoita kuti DDR5 ive sarudzo yakanaka yeartificial intelligence (AI) uye muchina wekudzidza data-yakawanda mabasa. Iye zvino DDR5 yave pamusika kwemakore matatu, ikozvino yakachipa uye yakanyanya kushandiswa.
Panguva imwecheteyo, DDR4 iri kubviswa zvishoma nezvishoma mumusika. Zvinonzi Intel's inotevera-chizvarwa Core processors haichatsigire DDR4, nepo AMD ichasiya tsigiro yeDDR4 painoburitsa yayo Ryzen 7000 akateedzana processors pakupera kwa2022.
Asi DDR4 ichiri kukurumidza ndangariro module kutsanangurwa, uye kana iwe ukatevera mutengo-kushanda, zvakakodzera kusarudza kuramba uchishandisa DDR4.
3, Musiyano Pakati peDDR4 vs DDR5
(1) Memory Bandwidth
Imwe yemisiyano mikuru pakati peDDR4 neDDR5 RAM kumhanya. Iyo JEDEC yakatarwa yeDDR4 inomhanya nekumhanya kunosvika 3200MHz, yakakwira kupfuura yekutanga 2133MHz pakuvhurwa, ukuwo iyo default yekumhanya yeDDR5 RAM iri 4800MHz, ine inoshanda yekumhanya inosvika 6400Mhz.
Kuenzaniswa neDDR4, ine DDR5, mitengo yekufambisa data inogona kuwedzerwa ne50%, uye maindasitiri pc vagadziri vari kuenderera mberi nekukurukura maitiro ekuwedzera bandwidth. Mune ramangwana, DDR5 inogona kumhanya pa8000MHz kana yepamusoro furemu mareti, kupfuura zvakapetwa kaviri chiyero chekuendesa data cheDDR4.
(2) Voltage
DDR4 inoshanda pa1.2V, nepo imwe neimwe DDR5 module ine yayo PMIC (simba manejimendi akabatanidzwa redunhu), inoda simba shoma, uye Vdd inodonha kubva 1.2v kusvika 1.1v.
Nepo simba rekuchengetedza 0.1V risingaite senge rakawanda, rinogona kuderedza kushandiswa kwemagetsi ne20%, kunyanya munzvimbo dzemaindasitiri dzinoda kuenderera mberi kwekushanda 24/7, kuita uku kwesimba kunogona kuchengetedza mari yakawanda.
Zvakare, kushandisa simba shoma kunoreva kushoma kupisa kunogadzirwa, izvo zvinobatsira kuvandudza kugadzikana kwechigadzirwa, kunyanya kune yakadzamirwa mhinduro.
(3) Kukwanisa
DDR4 inogona kutsigira maDIMM ane huwandu hunosvika 64GB. DDR5 inogona kutsigira kasere pakukwanisa kweDDR4 - kusvika pa512GB paDIMM, ichibvumira mushandisi mumwechete kubata mapurojekiti akakura, akanyanya ndangariro.
Nekudaro, mazhinji ma processor haakwanise kutsigira izvi parizvino. Iwo akanakisa mabhodhi epamusoro-ekupedzisira akadai seGigabyte Aorus Z790 Extreme X, inotsigira kusvika ku192GB yendangariro yakazara uye 48GB yemamodule ekurangarira akazvimirira.
Sezvo tekinoroji ichikura, isu tinotenda kuti ingangove nyaya yenguva maCPU asati ashandisa zvizere kugona kweDDR5.
(4) Kunonoka
RAM inoita senge chengetedzo yenguva pfupi yeCPU yemukombuta, ichibvumira kuwana nekukurumidza kumabasa anogara achiitwa, akafanana nepatinovhura akawanda maapplication pamafoni edu. Kana isu tikashandisa imwe, mamwe maapplication anoramba achimhanya kumashure, zvichiita kuti zvive nyore kukurumidza kuchinja pakati pawo. Iyo yakaderera iyo latency, iyo inokurumidza iyo CPU inowana mirairo yakachengetwa kwenguva pfupi mu RAM kuita mabasa.
Nekuenderera mberi kukwidziridzwa kweDDR, chizvarwa chega chega chendangariro chakawedzera CL zvichienzaniswa nechizvarwa chakapfuura, uye ndizvo zvakaitawo DDR5, asi nguva yekutenderera wachi yave kukurumidza. Yakasanganiswa neDDR5's hombe mukana mune yekupedzisira-yakakura yekumhanyisa kumhanya, inoda kubvisa iyo yakazara latency gap.
(5) Kuita
Kune inorema chiitiko kupa kana vhidhiyo faira encoding, DDR5 ine yakanyanya kukwirira kuita. Mushure mekuyedzwa, pane system yakashongedzerwa neDDR5, iyo yakareba bvunzo chiitiko muBlender yakapihwa imwe kusvika maminetsi maviri nekukurumidza; pane sisitimu yakashongedzerwa neDDR5, iyo vhidhiyo faira yakavharidzirwa neHandbrake yaive zvakare ingangoita miniti nekukurumidza.
DDR5 inokurumidza kupfuura DDR4 mumashandisirwo akanyanya, asi kumabasa emazuva ese, mutsauko muhupenyu chaihwo idiki uye DDR4 inokwana kuzadzisa zvinodiwa. Iwe unogona kusarudza zvichibva pane chaiyo application mamiriro.
4, Ko DDR5 iri nani zvakanyanya kupfuura DDR4?
Kubva pane sumo iri pamusoro, hazvina kuoma kuona kuti DDR5 iri nani chaizvo maererano nemabasa uye zvakanakira. Chekutanga, DDR5 inokurumidza uye inokwanisa kufambisa dhata pamwero wepamusoro, ichiita kuti sisitimu ishande zvakanyanya kana ichigadzira yakawanda data. Chechipiri, DDR5 ine bandwidth yakakwirira uye inogona kutumira mamwe data panguva imwe chete, iyo inobatsira zvikuru kune mabasa anoda huwandu hwakawanda hwekugadzirisa data, semitambo nekugadzirisa mavhidhiyo. Pamusoro pezvo, DDR5 inowedzera simba uye inoshanda kupfuura DDR4, uye inogona kuderedza kushandiswa kwesimba uku ichipa kushanda kwepamusoro, izvo zvinobatsira kuvandudza kushanda kwese kwehurongwa uye hupenyu hwebhatiri.
Nekudaro, mutengo weDDR5 wakakwira zvakanyanya. Pakazere, DDR5 isarudzo iri nani kune vashandisi vanoteedzera kuita kwepamusoro uye kugona kwakanyanya, asi kune vashandisi vese, DDR4 ichiri sarudzo inodhura-inoshanda.
5. Zvakakosha kusimudzira kuDDR5?
Ikozvino, DDR5 inokurumidza kupfuura DDR4, uye mabhodhi emazuva ano uye ma processor ari kudzima ndangariro zvishoma nezvishoma. Kana iwe uchida kutsvaga tekinoroji yazvino, unogona kukwidziridza kuenda kuDDR5, asi iwe unofanirwawo kukwidziridza bhodhi reamai uye processor uye kuona kuti kune magetsi akakwana.
DDR4 haisati yapera nguva pamusika, uye kune mimwe michina inoenderana kupfuura DDR5. Kuita kweDDR4 kuchiri kwakanakira mabasa mazhinji. Kana paine dambudziko nekuchengetedza huwandu, unogona kukwidziridza DDR4 memory kuenda ku32GB kana 64GB module. Kuwedzera bandwidth yendangariro kuchaita mutsauko mukuru pane kuchinja kuDDR5, uye inodhura-inoshanda.
