NVIDIA GeForce 820M - xyuas qauv, neeg xyuas thiab cov kws muaj txuj

GeForce 820M. Discrete graphics tsuj roj rau hauv nruab nrab hauv chav kawm ntawv ntawm mobile computers - ib tug GeForce 820M. Qhov no daim ntawv twb tso tawm nyob rau hauv thaum ntxov 2014 thiab tseem tseem mus yuav tau cov. Lub xub ntiag ntawm xws li ib tsuj roj tso cai rau lub laptop khiav feem ntau cov khoom ua si, txawm tam sim no, tab sis tsis nrog lub siab tshaj plaws qhov chaw.

niche adapter

Rau hnub tim, laptops, nyob ntawm seb lub peev xwm ntawm graphics raug muab faib raws li nram no:

1. Mobile nkag-qib system nrog ib tug tsawg kawg nkaus kev ua tau zoo theem ntawm ntau autonomy thiab kev ywj pheej tus nqi. Raws li ib tug txoj cai, xws li ib tug lub PC uas siv cov kev graphics card. Nyob rau hauv cov ntaub ntawv no, lub computer tso cai rau koj mus rau tsuas khiav lub feem ntau yooj yim thiab yam tsawg kawg xav ua si.

2. Mid-ntau laptops compulsorily nruab nrog discrete graphics subsystem, muaj ib tug txo autonomy thiab ib tug ntau dua theem ntawm kev ua tau zoo nyob rau hauv kev sib piv nrog mobile nkag-qib PCs. Nyob rau tib lub sij hawm, thiab tus nqi nce ho. Nws yog nyob rau hauv lub plawv ntawm xam thiab yog GeForce 820M.

3. Cov feem ntau tsim laptops yog nruab nrog high-kev ua tau zoo graphics accelerators. Tus nqi nyob rau hauv cov ntaub ntawv no lawv muaj ho ntau zog, tab sis autonomy yog tsawg heev. Kho vajtse xaiv xws xam tshuab cia kom daws tau tej teeb meem, xws li cov feem ntau xav tau ntawm qhov tseeb tiam ntawm cov khoom ua si.

Specifications graphics tsuj roj

это кодовое обозначение графического процессора, установленного в GeForce 820M. GF117 - yog codenamed graphics processor ntsia tau rau hauv lub GeForce 820M. Nta nws hais tias nws yog raws li nyob rau hauv lub architecture codenamed "Fermi". Tus heev tib yam semiconductor nti manufactured raws li cov qauv 28 nm txheej txheem. , 16 блоков TMU и лишь только 4 модуля ROP. Tus qauv ntawm xws li ib tug discrete graphics system muaj xws li shader modules 96, 16 thiab xwb TMU 4 ROP module blocks. Video processor moos zaus yuav varied rau hauv lub chav 719 rau 954 MHz, thiab blocks shader, nyob rau hauv lem, tej zaum yuav ua hauj lwm los ntawm 1438 MHz rau 1908 MHz. NVidia под названием GPU Boost, которая позволяет изменять частоту графического чипа в зависимости от степени сложности решаемо й задачи и уровня нагрева полупроводникового кристалла. Nyob rau hauv no yees duab card NVIDIA lub proprietary technology hu ua GPU Boost, uas tso cai rau koj yuav hloov lub zaus ntawm lub graphics nti, nyob ntawm seb cov neeg kawm ntawv kev nyuaj solved thawj qhov teeb meem thiab cov theem ntawm cov cua kub ntawm lub semiconductor nti. Direct Х версии 11.0 и OpenGL 4.5. Thaum lub software theem, txaus siab technologies xws li Direct X 11,0 thiab OpenGL 4.5.

nco subsystem

Basic configuration ntawm tus tsuj roj muaj 1 GB of RAM, thiab ib tug ntau tshaj version GeForce 820M - 2GB. Ib zaug ntxiv, muaj cov ntau high-ceev GDDR5 nyob rau hauv cov ntaub ntawv no muaj peev xwm yuav tsis muaj rau tej yam yooj yim yog vim li cas hais tias cov graphics nti yog aimed ntawm kev siv ntawm DDR3. Raws li ib tug tshwm sim, lub RAM xws nyob rau hauv cov ntaub ntawv no tau txo zaus. Raws, nyob rau hauv nrog cov video nti yuav siv GDDR5, tab sis ceev nreg yuav tsawg heev. Xijpeem nco bandwidth yuav muaj mus rau ib tug nqi siab tshaj plaws nyob rau hauv cov kev yees duab tsis DDR3.Razryadnost tsheb npav theem, qhov no tsuj roj - 64 me me, thiab lub cim xeeb moos - 2000 MHz.

Thaum tshav kub kub chaw

Thaum tshav kub kub pob GeForce 820M yog 15 watts. Raws li, qhov graphics tsuj roj yuav tsis tau active txias system thiab ntxiv hwj chim los ntawm lub hwj huam mov. Tab sis feem ntau manufacturers tseem Nkij los txuam rau cov phau ntawv sau active txias. Qhov no yog ua nyob rau hauv view ntawm lub fact tias cov ntawv feem ntau ceev thiab raws li ib tug tshwm sim, ib qho ntxiv thaum tshav kub kub lub dab ntxuav tes.

analogs

NVidia GeForce 820M превосходит по производительности любую интегрированную видеокарту от «Интел». Tam sim ntawd nws yuav tsum tau muab sau tseg tias qib ntawm kev kawm NVIDIA GeForce 820M outperforms tej kev graphics los ntawm lub "Intel". Piv txwv li, HD Graphics 4400 qauv yog 2.5 lub sij hawm qeeb qeeb tshaj tus hero ntawm no xyuas. Ib tug sib txawv me ntsis teeb meem no nrog cov khoom ntawm lub tuam txhab AMD. Nws hybrid processors yog nruab nrog ib tug haib ua-nyob rau hauv graphics subsystem thiab qhov sib txawv nyob rau hauv cov ntaub ntawv no yog yuav luag tsis muaj. Nrog discrete kev daws teeb meem ntawm no chaw tsim tshuaj paus yog ib tug ncaj competitor qauv Radeon R7 M360. Yog hais tias ib tug piv theem ntawm tus nqi yog lub graphics daws yog me ntsis kev kawm ntau. Nyob rau theem kev ua tau zoo sib npaug zos R7 thiab M360 GeForce 820M. Cov yam ntxwv lawv yog heev uas zoo sib xws.

Xyuas ntawm lub graphics card

Ntawm cov hoob kawm, tag nrho cov feem ntau xav tau cov khoom ua si tsis rub lub GeForce 820M rau siab kawg chaw. Xyuas yog tsuas yog cia li paub tseeb hais tias. Tab sis tsis txhob hnov qab tias nws yog nruab nrab-theem cov tshuaj. Yog li ntawd, qhov kev kawm ntawm nws nyob rau hauv nruab nrab theem, tus nqi piv rau kev nkag teb chaws-theem laptops saum toj no, thiab autonomy - ib tug me ntsis zuj zus. Cov mobile PCs muab xam txig ceev thiab ib tug zoo autonomy. Yog hais tias koj xav tau autonomy, ces xaiv ib tug tsis tshua kim phau integrated graphics, tab sis, yog hais tias koj xav tau nyiaj pab ntau tshaj kev kawm - peb yuav kim kim mobile computer nrog uncompromising kev kawm.
