Yintoni ikhadi mifanekiso yekhompyutha

Ngamanye amaxesha, le web inokufumaneka lo mbuzo, "yintoni ikhadi yemizobo." Nangona kubonakala ezingenamsebenzi, Noko ke, umntu owenza isigqibo ukuqonda okulufaneleyo intlonipho, njengoko efuna ukuqonda ukuba ifowuni ye computer.

Wonke umntu uyazi ukuba umsebenzi zonke izixhobo becomputing esekelwe ukumelwa yokubini inkcazelo. Ngubani na owakha wambona ukulandelelana amaqanda abo ephuma ephepheni okanye computer, uyazi ukuba kukho ukuqonda ukuba into phantse ayinakwenzeka. Oku kuchazwe lula, kuba onke la manani - uhlobo lwe micro-r for transistors. Yintoni na ke nesihlobo ngasentla, umbuzo wokuba yintoni ikhadi mifanekiso? Direct! Izinto uzibonayo ekhusini i ikhompyutha yedijithali imijelo data lwangaphakathi ziguqulwa zibe abalinganiswa abantu ukuluqonda. Ingxaki yale nkqubo yenguqu nje wabelwa ukuba ikhadi levidiyo.

Makhe ukuchaza ingqiqo ka "yintoni na ikhadi yemizobo." Video iadaptha (ikhadi graphics) - isixhobo yenzelwe ukubonisa nemizobo kwi kwikhusi (efana indlela imizila bomshicileli ephepheni). Ngaphezu koko, hayi zonke iinkcukacha digital, kwaye ngendlela ethile ilungiswe. Umzekelo, xa uzama ukubonisa kumsinga yedijithali wemiyalelo disk nzima nge ividiyo, akukho nto yenzekayo. Yonke idatha lwangaphakathi pre-eziqulunqwe CPU ngesixhobo nganye ithagethi: ukuba oluboniswe idilesi olifunayo ibhasi iboniswe njalo njalo.

Kodwa yonke le ilapha ngasentla isebenza kuphela kwicandelo software na, ke ngoko, ndicinga ukuze omnye-kabini, singakwazi ukuphendula ngokweenkcukacha lo mbuzo, "yintoni ikhadi yemizobo." Ngokomzimba, yinto ibhodi ukwanda Imigudu ibe kwisokethi ohambelana (slot) loMthetho motherboard (mainboard). Phantse zonke amaqhoshana yokuzonwabisa mihla zenzelwe i PCI Express.

Awona macandelo alandelayo ebhodini: umqhubekekisi indlela yemizobo, isilawuli, ividiyo khadi (RAM kunye ROM), i Isidibanisi ibhasi kunye neziphumo isinxibelelanisi, iDAC, inkqubo okupholisa, izinto ezihamba. Kwezinye iindlela, uluhlu ungadluliselwa ezinamacandelo ezongezelelweyo.

video i parameters becala ezimiselwe kumqhubekekisi ehlengahlengisiweyo graphic. deal yangoku iinkampani babo obunemveliso ezimbini - AMD (ATI), kunye NVidia. Isabelo nezinye ezincinane, nangona ezaziwayo-kakuhle Intel nayo uzama ibango isabelo sabo emarikeni.

iprosesa yemizobo (GPU) iye ukudala umfanekiso kwedatha enikiweyo yi isicelo. Inani transistors lidlula kweli nani kumqhubekekisi Central, nto leyo ibonisa yokusebenza yayo nanto. Hi ndlela leyi, le nto ngakumbi nangakumbi uyakwazi ukufumana iinkqubo ezizodwa ukuba enze izibalo kwi GPU. Ewe, kwaye izicelo yokudlala ngokusebenzisa amathuba enikiweyo (PhysX, DirectCompute) kudala wafunda indlela yokusebenzisa izibonelelo zalo izibalo, non-imifanekiso.

Le isilawuli inoxanduva intsebenziswano lememori kwakunye iibhasi bangaphakathi kunye nabangaphandle. Bit bit ibhasi lwangaphakathi - lelona nani yesibini emva ukubaluleka yokusebenza GPU. Ngoku kwasasazwa iimodeli 64, 128, 256 okanye ngaphezulu ziintanda. Zuza ngaphantsi kwe 128 ayikhuthazwa.

kufuneka lememori khadi yemizobo kugcino nokwenza imifanekiso okudalwe GPU, ukwalathisa imveliso kwikhusi. Luphawulwa uhlobo iitshiphusi ezifakwe (DDR - GDDR5) kunye nomthamo. Izisombululo fastest eza GDDR5. imidlalo Modern ifuna ubuncinane i-512 MB of umthamo (kuxhomekeke kwizicwangciso).

ikhadi nganye, njengokuba sele kukhankanyiwe, yenzelwe ivili ethile. Ngoku ngokubanzi PCI Express 16 Maxa wambi kukho PCI, kodwa kungona iindleko. Kwiminyaka emininzi eyadlulayo, iikhompyutha walawula i AGP ibhasi, kodwa Intel, njengesiqhelo, ngexesha ukutshitshisa kuyo.

O isinxibelelanisi ichaza i interface ngalo ukwazi ukuthumela i uphawu ukuya esweni. Ezininzi kubo: kuphelelwa D-INKQUTYANA, DVI digital, uqhagamshelwano lwetshiphu emsebenzi yanamhlanje, Bonisa Port, njalo-njalo.

Maxa wambi ikhadi yemizobo ziyinxalenye CPU; kulo mzekelo, isebenzisa inkqubo inkumbulo, kwaye Isidibanisi imveliso leyo soldered kwi motherboard. Ukusebenza kwezi izisombululo unika kunoogxa zangaphandle.
