Graphics tsuj roj NVIDIA GeForce GT 640: specifications, xyuas thiab lub sij hawm

, конечно, выдающимися назвать нельзя, но его наличия в составе компьютера на момент начала продаж было вполне достаточно для запуска большинства игрушек на тот момент. Graphics card midrange 2012 tso tawm nrog pheej yig tus nqi thiab tsim nyog kev specifications - nws yog tag nrho hais txog lub NVIDIA lub GeForce lub GT 640. nta adapter, ntawm chav kawm, tsis tau hu ua koj, tab sis nws muaj nyob rau hauv nyob tus yeees ntawm cov computer thaum lub sij hawm ntawm pib ntawm kev muag khoom yog txaus khiav feem ntau cov khoom ua si nyob rau hauv lub sij hawm ntawd. Hais tias yog dab tsi no video card thiab nws cov tuition yuav ntxiv nws.

Niche graphics adapter

для стационарных системных блоков условно подразделяются на две большие группы: NVIDIA graphics accelerators California lub tuam txhab rau ntawv system blocks conventionally muab faib ua ob yam loj xws li:

• Hwm theem kev daws teeb meem nrog lub siab tshaj plaws ceev, muaj hwj chim noj thiab nqi. Kev specifications rau hauv no hwm, tseeb, tawm ntawm kev sib tw. Video card ntawm no pab pawg neeg muaj txoj kev xaiv tsiaj GTX.

• Qhov thib ob pab pawg neeg ntawm graphics phaib ntawm no ua chaw tsim tshuaj paus ntawm tej khoom xws GT. Nyob rau hauv cov ntaub ntawv no, lub video subsystem kev kawm ho hauv qab no cov kev specification - coj tus, tab sis tus nqi - ntau puas siv tau. Nws yog qhov no pab pawg neeg ntawm pab kiag li lawm thiab belongs rau lub NVIDIA lub GeForce lub GT 640. nta ntawm cov khoom no yog ib zaug dua tseeb.

adapter chaw

Zoo (rau xyoo 2012) twb xaiv nyob rau hauv NVIDIA lub GeForce lub GT 640. nta nyob rau hauv no computer Cheebtsam yog raws li nram no:

RAM graphics tsuj roj

Nyob rau hauv 2012, muaj ib tug gradual kev hloov ntawm ib hom ntawm RAM rau lwm tus neeg. вытеснялся из рынка GDDR5. Yuav kom ua tau ntau leej - GDDR3 GDDR5 squeezed tawm ntawm lub lag luam. Raws li ib tug tshwm sim, cov qauv no yuav muab nruab nrog ib tug graphics tsuj roj raws li cov thawj hom RAM, thiab lwm tus neeg. NVidia GeForce GT 640 — 2Gb. Qhov tsawg kawg nkaus tus nqi ntawm lub cim xeeb nyob rau hauv cov ntaub ntawv no yog 1 GB, thiab qhov ntau tshaj ntawm RAM rau NVIDIA GeForce GT 640 - 2GB. Nta video tsis xws qhia hais tias nws tau teem rau lub cim xeeb daim nrog kev khiav hauj lwm frequencies ntawm 1800 MHz. GDDR3. Raws li ib tug tshwm sim, optimally nyob rau hauv xws accelerators siv GDDR3. GDDR5 получить дополнительный прирост быстродействия было практически невозможно. Tab sis txoj kev siv cov GDDR5 tau ntxiv ceev nce twb yuav luag tsis yooj yim sua. Lub cim xeeb chaw tos tsheb loj nyob rau hauv no GPU yog 64 me me.

Thaum tshav kub kub tsuj roj hom

Thaum 49 W yog thaum tshav kub kub pob NVIDIA GeForce GT 640. card tib yam ntxwv feem ntau zoo ib yam li cov ntawv teev lus qhia uas nyob rau ntawm ib tug nqi ntawm no parameter, lub txias system tej zaum yuav passive. Tiam sis ntawm no, qhov no California-raws li lub tuam txhab tau txiav txim siab mus ua si nws muaj kev ruaj ntseg, thiab ua neej ntawd accelerators xws systems yuav txawm peem rau nrog ib tug active heatsink (ie, txias). Nyob rau hauv ib tes, qhov no mus kom ze pub rau suab tej teeb meem no tsis txhob overheating video accelerators, thiab lwm yam - ntxiv ntxiv rau tag nrho cov PC decibels ntawm suab nrov theem. ⁰ С. А вот минимальная мощность системы электроснабжения системного блока ограничивалась 300 Вт. Qhov siab tshaj plaws permissible kub rau qhov muab tsuj roj yog 95 ⁰ C. Tab sis qhov tsawg kawg nkaus fais fab mov system unit ntawm lub system twb tas rau 300 watts.

Lub ntsiab sib tw ntawm tus hero ntawm no los xyuas yog kev mus rau hauv lub CPU graphics phaib. Kev tsis lawv cov suab tib yam, raws li tau zoo raws li kev ua tau zoo. Txawm lub siab tshaj plaws pes tsawg tus ntawm lawv tib yam NVIDIA GeForce GT 640 - 2 GB. Cov yam ntxwv ntawm graphics processors muaj ib tug ntau ntawm dab tsi yog tseem yog tib lub. Lub ntsiab kom zoo dua ntawm ua-nyob rau hauv accelerators - yog hais tias lawv tau raug Ameslikas muaj li ntawm PC thiab muaj yog tsis muaj yuav tsum tau yuav nyias. Tab sis xws li ib tug discrete graphics yuav tsum ntxiv yuav ib tug ntxiv npaum li cas. Yog li ntawd, nws nrhiav tau yog tsis txhaum xwb nyob rau hauv cov ntaub ntawv ntawm lub system unit kho vim muaj ib tug malfunction ntawm uas twb muaj lawm graphics card nyob rau hauv lub shortest tau lub sij hawm thiab nrog tus nqi qis tshaj tau nqi.

Nqi. Xyuas

Nyob rau hauv lub tshiab lub xeev ntawm ib tug computer accessory yog tsis tau mus yuav: nws tau ntev tau rho los ntawm cov lag luam, thiab stocks - ntse muag. Lub xeev kev txhawb xws li ib tsuj roj yuav tsum tau muas ntawm ntau yam hauv internet khw ntawm ib tug nqi ntawm 3,000 mus 3,500 rubles. GT 640 в особом исполнении с улучшенной системой охлаждения. Xyuas ntawm lub feem ntau cov tswv ntawm lub computer Cheebtsam qhia, thawj, uas cov tib theem ntawm kev ua tau zoo yog niaj hnub integrated graphics subsystem thiab NVIDIA GeForce GT 640. ASUS (yam ntxwv ntawm cov khoom nyob rau hauv no hom yeej ib txwm ib yam dab tsi tshwj xeeb sib txawv los ntawm cov kev sib tw) tau tso tawm GT 640 nyob rau hauv ib tug tshwj xeeb version nrog ib tug paub txias system. GT 640-2GD3. Cov qauv no GT 640-2GD3. Raws li ib tug tshwm sim, cov adapters yuav ceev thiab tiav los ntawm no xyov koj qhov nce nyob rau hauv ceev nyob rau hauv kev sib raug zoo mus rau lub neej tshiab nimno integrated graphics. GT 640 и имеют схожую производительность . Raws li rau tus so, raws li tau sau tseg ua ntej lawm, cov kev tsis muaj tus kos graphics dub GT 640 thiab muaj zoo xws li cov kev ua tau zoo.

tau

Thaum lub sij hawm ntawm nws tso tawm tus tsuj roj tsim nyog nruab nrab hauv chav kawm ntawv yog NVIDIA GeForce GT 640. nta nws yeej tseem ceeb thiab tso cai rau koj mus khiav feem ntau uas twb muaj lawm cov khoom ua si nyob rau ntawm lub sij hawm. Tam sim no tus tsuj roj maj poob mus rau hauv lub ya ntawm nkag-qib cov khoom, thiab tam sim no nws muaj mus hais rau kev yees duab subsystem. Cov yav tas muaj ib tug tseem ceeb kom zoo dua: lawv muaj nyob rau hauv lub PC thawj, thiab rau lawv yog tsis muaj yuav tsum tau them nyiaj ntxiv.
