Chii kombiyuta yacho Graphics kadhi

Dzimwe nguva, padandemutande anogona kuwanikwa mubvunzo "chii Graphics kadhi." Zvisinei, kunyange zvazvo zvichiita sokuti chiduku, munhu akasarudza kunzwisisa sezvarinokodzera kuremekedzwa, sezvo anoda kunzwisisa umhare pakombiyuta.

Munhu wose anoziva kuti basa zvose kadambari mano kwakavakirwa binary cherudo ruzivo. Ndiani akamboona kutevedzana kwezviitiko Kwemagandanga Achishandisa Kombiyuta hwokurara papepa kana pakombiyuta, anoziva kuti pane kunzwisisa kuti chinhu kwakaoma zvisingaiti. iri nyore Izvi zvinotsanangurwa, nokuti zvose izvi nhamba - rudzi Micro-Ops kuti transistors. Chii ukama pamusoro, mubvunzo kuti Graphics kadhi? Direct! Chii tinoona pamadziro chinhu womukati kombiyuta digitaalinen mashoko Hova dzikwanise kucherechedzwa kwevanhu vatambi. The dambudziko tishandurwe iyi chete basa vhidhiyo kadhi.

Ngationei Tsanangura pfungwa "chii Graphics kadhi." Video adhaputa (Graphics kadhi) - zano zvakagadzirirwa kuratidza Graphics pamusoro chidzitiro (akafanana sei aidhinda rinodhindira pamusoro paper). Uyezve, kwete mashoko ose digitaalinen, uye mune imwe nzira agadzirwa. Somuenzaniso, kana ukaedza kuratidza digitaalinen karwizi zvakaoma dhisiki mirayiro Via video, ipapo hapana chinoitika. womukati date zvose pre-kugadzirira nokuda CPU nerimwe chipfuro mudziyo: avakaita zvinodiwa kero bhazi zvinoratidzwa nezvakadaro.

Asi zvose pamusoro rinongoshandisirwa software chazvo, saka, tichifunga kuti munhu mumwe chete angoramba, hatigoni kuita zvizere kuti mubvunzo "chii Graphics kadhi." Panyama, chiri kuwedzera Board kuti plugs kupinda runoenzanirana panosangana (slots) ari motherboard (mainboard). Zvinenge zvose ano Video adapters zvakagadzirirwa kuti PCI Express.

Zvinotevera zvinoumba vari mungarava: a Graphics processor, controller, mavhidhiyo kadhi ndangariro (RAM uye ROM), bhazi connector uye goho connector, DAC, kutonhora maitiro, nechati zvinhu. Mune dzimwe mhando, mazita anogona kuwedzerwa Zvimwe zvinoriumba.

Video parameters vari zvikuru pakutsvaga akagadziridzwa kwakajeka processor. Kuyerera kwadzo kugadzirwa ngaakuitirei makambani maviri - AMD (ATI), uye NVidia. Mugove mumwe duku, kunyange zvazvo aizivikanwa Intel ari kuedza vanoti mugove wavo kumusika.

Graphics processor (GPU) rave kusika mufananidzo nemashoko kushanda. Kuwanda transistors kwazvo mufananidzo uyu ari nechepakati processor, ndiro anoratidza zvayo risingaenzaniswi unongotaura. Zviya, ndokusaka zvakawanda unogona kuwana unyanzvi hwakasiyana zvirongwa kuti aite Masvomhu pamusoro GPU. Hongu, uye uchitamba mutambo kushanda kuburikidza mikana inopiwa (PhysX, DirectCompute) kare kare vakadzidza sei kushandisa zviwanikwa zvayo kuti masvomhu, asiri kuri.

The controller iri tasked kudyidzana nendangariro uyewo nechinzwano kwokunze nemabhazi. Ikakuruma ikakuruma rekambani bhazi - ndicho nhamba yechipiri pashure chokupika GPU kukosha. Now akagovera yokutevedzera kubva 64, 128, 256 kana kupfuura matomu. Wana asingasviki 128 haisi inokurudzirwa.

Kuyeuka pamusoro Graphics kadhi inodiwa kuchengetera uye kubudiswa zvifananidzo zvakasikwa nokuda GPU, kutungamirira goho kuti chidzitiro. Dzinoratidzwa rudzi akagadzawo machipisi (DDR - GDDR5) uye vhoriyamu. The uchitsanya mhinduro kuuya GDDR5. mitambo Modern zvinoda zvinenge 512 MB cheBhuku (kunoenderana pazviruva).

kadhi nomumwe ari, Sezvambotaurwa rakagadzirirwa kuchiitirwa tai. Zvino zvikuru kushandiswa PCI Express 16. Dzimwe nguva pane PCI, asi dzakanga mutengo. Makore akawanda akapfuura, makombiyuta vushe AGP bhazi, asi Intel samagariro panguva yokubvisa nayo.

O connector rinotsanangura chinhu inowanikwa naro unogona kutumira chiratidzo kuna Monitor. Vanoverengeka vavo: yakatopfuura D-SUB, digitaalinen DVI, HDMI ano, Ratidza Port, uye zvichingodaro.

Dzimwe nguva Graphics kadhi iri chikamu CPU, muchiitiko ichi, icho anoshandisa hurongwa kuyeuka, uye goho connector iri soldered pamusoro motherboard. Chokupika zvinogadzirisa izvi anopa kwokunze dzomuzana.
