ATI muaj Radeon HD 5470: Nta

Nkag tau rau hauv Lub ib hlis ntuj 2010, ib tug video adapter rau mobile ATI muaj Radeon HD 5470 computers tau teem rau lub creation ntawm computational midrange. Tej laptops, ib txhais tes, muaj txaus kev kawm zoo thiab paub daws nrog rau feem ntau yooj yim paub tab tsis muaj teeb meem. Nyob rau lwm cov tes, muaj ib tug discrete graphics tso cai nyob rau ntawm lub sij hawm kom tau ib tug zoo "gameplay" nyob rau hauv feem ntau ntawm cov khoom ua si, tab sis tsis yog lub feem ntau zoo tshaj plaws ntawm lub tso tawm kom pom duab.

no adapter ya ntawm lub lag luam

Heev, heev uas yuav tsum tau yog muab tso rau pem hauv ntej rau mobile discrete graphics adapter. Nyob rau hauv ib tes, lawv yuav tsum tau ntawm siab zog efficiency. Yog hais tias tus mob no yog tsis raws li hais, cov autonomy ntawm tus ntaus ntawv yuav raug txo kom tsawg ho. Nyob rau lwm cov tes, qhov kev kawm lawv yuav tsum tau nyob rau ntawm ib taus thiab txawm muaj ib yam npoo. Laptop yuav nyob rau hauv ib tug txaus ntev kev pab cuam lub neej, thiab yog hais tias koj tsis txaus siab rau lub caij nyoog kawg no mob, nws yuav ceev nrooj ua obsolete. данной модели успешно применялись в сегменте ноутбуков среднего уровня в 2011 году. Nws yog ib tug harmonious ua ke ntawm high efficiency thiab tau kawm, thiab yog lub hauv paus ntawm ATI muaj Radeon HD 5470. Graphics Card ntawm cov qauv no muaj lawm siv tau ntse nyob rau hauv lub ya ntawm mid-range laptops nyob rau hauv 2011. Nws yog nyob rau no me me ua lag luam ntawm mobile discrete graphics phaib thiab cov kev txiav txim siab twb tswj.

Kev specifications ntawm tus tsuj roj

Nws moos zaus yog taag thiab muaj ib tug nqi ntawm 750 MHz. PCI-Express в модификации 16Х и версии 2.1 . Raws li ib tug kev twb kev txuas interface ntawm tus yees duab daim card mus rau lub system board yog yuav tsum tau siv nyob rau hauv PCI-Express 16X kev hloov kho thiab version 2.1. Nyob rau hauv kev xyaum kuj nrhiav laptops nrog versions ntawm lub interface 2.0 los yog 3.0, uas siv daim card no. Tab sis ntau npaum nce nyob rau hauv cov nqe lus ntawm kev ua tau zoo yog tsis muab. Nyob rau hauv thawj cov ntaub ntawv, tus tsuj roj lag luam yog txiav txo kom 2.0, thiab nws cov kev ua tau zoo yog poob. Nyob rau hauv lub thib ob cov ntaub ntawv yog tsis siv tag nrho cov kev pab ntawm lub motherboard, thiab vim hais tias ntawm no, qhov kev kawm ntawm ib tug computer system poob rau hauv qab no lawv tshaj plaws muaj peev xwm. CrossFire. Nyob rau theem ntawm cov kev kho vajtse specifications ntawm lub crossfire technology pab txhawb nqa tau tshaj tawm hais tias qhov no tsuj roj. Hais tias yog, tus tsuj roj yuav ua hauj lwm nyob rau hauv tandem nrog rau lwm cov adapters nyob rau hauv no series, thiab yog li yuav tsum tau ho ua rau kom cov kev ua tau zoo ntawm cov computer system.

ноутбуки с двумя дискретными ускорителями невозможно. Nyob rau hauv kev xyaum, kom tau raws li laptops nrog ob tug discrete accelerators tsis yooj yim sua. Raws li ib tug tshwm sim, qhov no technology nyob rau hauv lub ntiaj teb no ntawm mobile computers twb tsis tau txais tseem ceeb txoj kev loj hlob. Shader units hauv ib tug muab video ntaus ntawv 80 tau pom tau hais, thiab lawv zaus ntawm 750 MHz, thiab lawv ua nyob rau hauv synchronism nrog lub graphics processor. Rasterization modules nyob rau hauv no tsuj roj tsuas yog 8 daim. VGA ( максимальный формат картинки 1536х 2048) и два цифровых порта HDMI ( формат картинки — 1080р) и DVI (1600х2560). Daim ntawv teev cov kev txhawb video tso zis tej ntaub ntawv accelerators xws li analog VGA (nyiaj pab ntau tshaj hom duab 1536h 2048) thiab ob cov HDMI ports (hom duab - 1080) thiab cov DVI (1600h2560).

Fais fab kev noj, kub tswj

TDP rau tus tsuj roj twb tshaj tawm nyob rau theem ntawm 15 watts. Ib zaug ntxiv, xws li ib tug muaj hwj huam noj tus nqi yog tsis tau tso cai rau siv nyob rau hauv ua ke nrog nyob rau hauv xws li ib tug passive tshav kub tshem tawm system adapter. Tag nrho accelerators cov qauv no compulsorily nruab nrog active txias system. Cov nqi siab tshaj plaws ntawm kub rau no semiconductor dlaws tau teem rau ntawm ib ncig ntawm 70 ⁰ C. Txawm nyob rau hauv lub feem ntau complex duab tso zis hom, qhov no parameter tsis pub tshaj 62-65 ⁰ C. Tsuas yog nyob rau cov ntaub ntawv ntawm breakage ntawm lub thawv txias, nkag mus rau hauv lub txias system yuav ua tau tiav los ntawm no tswb tus nqi.
