GDDR5 - zviri pamusoro vhidhiyo kadhi? Chizvarwa rechishanu DDR SDRAM ndangariro

Vaya vokutanga vakasarudza kuisa pamwe yako PC, kana kuti kunzwisisa izvozvo nechomukati, kutanga nechiso akawanda dzinovhiringidza mazwi. Kana isu kuzarura kombiyuta pakavha, tinoona yakawanda waya, ndiro, mafeni, kupisa rinosakara, etc. Kuti tidzivise kukonzera kamwe zvakare tenzi uye kwete kuonana neshamwari, nyore kunzwisisa.

Nhasi tichataura kudaro dzinonakidza pfungwa pamusoro, sezvo GDDR5. Kuti, vakawanda havazivi, vamwe vangafunga mamwe achiziva uye kunzwisisa. Kuti varege kuvhiringidza muverengi, zvinokosha kutaura pakarepo kuti GDDR5 - ndiye ndangariro. Nei ndezvaJehovha uye kwaakanga ari, tinenge kuziva zvakawanda.

Video ndangariro

Kwete Dump pamusoro asingazivi munhu kamwe boka mashoko, zviri nani kuti uende rumwe ruoko. Tose tinoziva pamusoro motherboard, iyo anoiswa mukati PC nyaya. Anofanira kwakabatana kuti processor, simba wedzerai, mavhidhiyo kadhi, RAM nezvimwe zvinhu. Kunze kuti pane ndangariro wegadziriro, anewo zvakafanana pfungwa, uye vhidhiyo kadhi.

Saka, pane izwi - Video ndangariro. Kutaura zvazviri, ndizvo zvakafanana kuti gondohwe, asi ndiye zvakananga kuchengetera chikamu kuti mashoko kuti kunodikanwa kuti kubereka chifananidzo chidzitiro. Kusiyana kuyeuka rose ezvinhu, zviri chete basa nehasha kuti vhidhiyo. Naizvozvo, vhidhiyo ndangariro chip anoiswa pamusoro Graphics kadhi.

kutanga

Tanga kuziva wako akasiyana RAM kunodikanwa yokutanga kushanduka. Mukuru chimiro "RAM" anonzi kuti kuyeuka DDR. Zvino, zvichida, hazvibviri kuwana motherboard iri mhando. Uchishandisa voltage aiva 2.5 volts. Chokwadi, achitarisa shure panguva dzose mhando kare, tinogona zvakachengeteka kutaura kuti DDR kuyeuka ukapisa zvikuru magetsi.

mhando

Tisati tadzidza nezvake chii chiri pamusoro GDDR5 Graphics kadhi, zvinokosha kunzwisisa kusiyana. Mhando okurangaridza nguva dzose, zvakanga zvisingaverengeki. Rondedzera nomumwe hazvina musoro, iwe unofanira saka kuenda zvakananga pfungwa.

Kazhinji, munhu chero mukana ndangariro DRAM yacho zita. It kutanga zvakazivikanwa nyika munguva Second World War. Asi kuratidzwa kwayo ano izvozvo akazviratidza muna 1966. Long nguva Developers uye vagadziri vakaedza kuvandudza ndangariro. Mumwe achifananidzira rokutanga vakava PM DRAM mukutanga 90-ies wekupedzisira remakore.

Asi Developers vakanga zvose nguva kuwedzera nokukurumidza uye bhuku "RAM". DDR SDRAM - After kuedza matanhatu, imwe mhando itsva ikaonekwa pamusika. Akava zvakasiyana yapfuura neshanduro Enhanced Data Rate (ruviri). Izvi mhando iri kutanga iiswe Graphics makadhi. Nokufamba kwenguva, mashoko Developers vakasarudza kushandisa RAM uye chipset.

hwaro

Zvinofungidzirwa kuti GDDR5 akazviratidza kuonga DDR SDRAM. Izvi shanduro iyo wechishanu waiva yakawanikwa kuti kushanda. softs izvi zvinoda yakakwirira bandwidth. The mugadzi kuti pfungwa iyi razova chechina-chizvarwa ndangariro. Vose vari kwakavakirwa DDR3. The Kukurukura chiteshi yava nekaviri, pane buffers noupamhi 8 matomu.

Zvinofadza kuti ichi mhando basa iri yakawanda vagadziri. Saka zvokutsvakurudza "denderedzwa" vaiva Hynix, Qimonda, Samsung uye JEDEC. Kushamisika ndechokuti kushanda navo uye kambani AMD. Zvakatora refu kwazvo nguva, uye kubvira pakutanga kuipedza akatora makore matatu. Panguva iyi Developers vakakwanisa kuzadzisa nemigumisiro yakanaka.

Zvadaro tinodzidza zvakawanda pamusoro GDDR5, chii uye kuti chii. Asi kwete vose vanogona kushandisa ndangariro ichi sezvo Specs vayo vachiri dzichiumbwa. Kubva ayo nzira machipisi kushanda pasi voltage pamusoro 1.5 V, uye arambe achirema yakanga 0.5-2 GB. maitikiro yavo kunosvika 4000 MHz, uye pashure penguva vakakwanisa kumutsa mufananidzo uyu kusvika 7000 MHz.

Akatoratidza akazviratidza ari arambe achirema 1 Gbit Chip muna 2009, papera gore - pagungano arambe achirema 2 Gbps. Zvapedzisira nzira yave inoumbwa 50-nm muitiro michina. By pakutanga 2015 kukura kwakaita kuti zvakaisvonaka zvabuda. Chip arambe achirema yakasvika 8 Gbps, uye nhema muitiro akanga achishanda kuti 20 nm. Ichi chinyorwa pedhi akauya vachitungamirirwa boka Korean Samsung.

Specification

Kuti udzidze zvakawanda pamusoro pamusoro GDDR5, kuti ndosaka tichifanira ndangariro ichi, zvakakosha kuti funga dzinokosha unhu, iyo zvino kushandiswa vagadziri zvose. Sezvo wava pachena musoro tsamba «G» ndiye anokonzera yokuti Graphics. Kureva, kwakadai ndangariro runodikanwa vhidhiyo kadhi.

GDDR5 akasunungurwa pasi Standardization. Nokutungamirira 8n mapurani, pamwe configuration yacho inowanikwa rinomutsa, uyewo zvemichina anovandudza unongotaura. Mumwe Chip ane makubhiti 32 matomu uye muviri akanga 170 vokukurukura. Process zvemichina ndiyo 40 nm.

Kakawanda kunogona tsunga ne parameters maviri. Kana rokutanga inoratidza kukosha 1250 MHz, wechipiri achava kureva kuva akaenzana 2500 MHz, kaviri. Manufacturers kazhinji dzinoratidza frequencies siyana, asi kuchinjwa mwero iri nguva dzose zvakafanana.

The chikuru mukana dzinokura kwave kuvandudza throughput. Kusiyana chizvarwa chechitatu video, yechishanu run rakanga mubhazi ikakuruma makubhiti 128/256. Munzira dzakawanda rakabatsira ndiponese vamwe zviratidzo. Saka, imwe 512 ikakuruma GDDR3 yaishandiswa matai. Uyu mufananidzo yakawedzera Chip saizi, ayo kavha, uye nokudaro mari muenzaniso yose. Video kadhi iri mhando kuparadzwa uye mukuru yakawanda simba.

okusuma

Zvino tinoziva GDDR5, kuti ndiye vhidhiyo ndangariro, basa achitungamirira vagadziri. Hazvishamisi, muenzaniso vhidhiyo kadhi wokutanga akazviratidza muna 2008, zviri kubva, AMD. Akava ATI Radeon HD 4870. It dzaitaurwa mushanduro maviri, izvo zvakasiyana Vhoriyamu 512 MB uye 1 GB.

Paiva yemashoko Nvidia Geforce. GDDR5 ichakwanisa azviise dzakatevedzana makadhi, pakati zvakanga :. GTX 550, zviri GTX 560, zviri GTX 580, zviri GTX 590, zviri GTX 660, zviri GTX 680, etc. Uyezve, kwakadai ndangariro zvino anowanikwa wechina shanduro Dreamcast kunyaradzana. Panguva iyoyo yakaiswa imomo sezvo negondohwe.

zvakawanikwa

Nokupfupikisa zvose pamusoro, zvakakosha kuziva kuti nguva yakawanda yapfuura kubva azviratidza RAM. Video ndangariro yave vakashanduka uye akaumba. Zvino rudzi wechishanu vasina zvikuru kukwira zvose. Tichishandisa achangobva akazozivikanwa rumwe rudzi - GDDR5X. Ndiye kaviri sezvo kutsanya. Kunyange zvakadaro, zviri zvikuru akabvunza GDDR5 ndangariro, kwete chete kuva chezvinonhuwira vhidhiyo kadhi, asi uyewo yoga RAM Chips.

Zvino mukuru kutyisidzira, izvo zvinogona kukonzera kunyangarika kwakadai ndangariro pamwe musika ndechokuti pokudenga ane kumwe kutanga uye kuvandudza. Uyezve, saka kure havana kukwanisa kugadzirisa dambudziko kumusoro simba rakawanda. Kunyange zvazvo tsika zvaiitwa shanduro iduku zvikuru, asi hapana risingabereki kugadzirisa. Uyezve, vakapiwa kuitika kune overclocking, dambudziko yakakwirira nesimba zvinodyiwa rokukurumidzira uye supercedes.
