Graphics adapter GeForce GTX 745: zoo tagnrho nqi koj tshuav ntawm cov nqi thiab zoo

Zoo ua ke ntawm nqi thiab kev ciaj ciam ntawm lub hom phiaj tso cai rau kev siv ntawm video card GeForce GTX 745 nyob rau hauv lub nkag teb chaws-theem gaming tshuab. Ib txhia niaj hnub ua si nyob rau hauv nws yuav mus rau nruab nrab nqis, thiab ib co - nyob rau hauv yam tsawg kawg nkaus. Tsis tas li ntawd, ib txhia laus software daws nyob rau hauv cov ntaub ntawv no yuav tsum khiav nrog lub siab tshaj plaws zoo. Nws yog ib qhov tsuj roj yuav tsum tau tham tom qab.

tso rau Solutions

Lub GeForce GTX 745, feem ntau teem rau lub ya ntawm tsawg tus nqi nkag teb chaws-theem gaming computers. Nyob rau hauv cov ntaub ntawv no, nws tsis yog txaus thiab cia peb mus daws tau tej teeb meem, tab sis nws yuav tsis tau txaus rau qhov nruab nrab theem ntawm lub computer. Nyob rau hauv tas li ntawd, nws yuav tsum tau muab sau tseg tias nyob rau hauv ib tug dawb ua lag luam nws yog yuav luag tsis yooj yim sua mus nrhiav tau. Nws muaj peev xwm yuav xa kom sai li sai raws li ib tug loj scale thiab rau OEM assemblers ntawm computer systems. Yog li ntawd, nws yuav tsuas yuav muas raws li ib feem ntawm ib tug computer.

Graphics nti. nco subsystem

Lub GeForce GTX 745 yog raws li nyob rau hauv lub GM107 graphics processor, uas, nyob rau hauv lem, yog raws li nyob rau hauv lub Maxwell architecture. Qhov no nti yog ua nyob rau ntawm lub nqi ntawm 28 nm txheej txheem technology thiab rau nws cov pob zeb ntais substrate 1870 yog millionov transistor ntsiab. Qhov luaj li cas ntawm cov substrate nyob rau hauv cov ntaub ntawv no yog 148 hli ^2. Nws yog duab processor 384, lub moos zaus uas nyob rau hauv lub nominal hom yog 1033 MHz.

Rasterizing modules - 16, thiab texturing units - 24. RAM xws aims mus ua hauj lwm nyob rau hauv nrog txheem GDDR3 chips nrog ib zaus ntawm 1800 MHz. Nyob rau hauv tej rooj plaub, manufacturers qhia lub xub ntiag ntawm standard GDDR5 chips, tab sis txawm yog hais tias lawv yog tsim los pab, lub tiag tiag tus nqi ntawm yuav tsum raug txo kom lub siab tshaj plaws tau 1800 MHz. Hais tias yog, tej nce los ntawm kev siv ntawm ntau high-ceev nco yog. Tau video tsis tagnrho tej zaum yuav 2GB los yog 4 GB. Tag nrho cov me ntsis RAM tsheb npav yog 128 me me, uas lub cev txheej yog muab faib ua 2 feem ntawm 64 khoom. Thaum kawg, qhov no tso cai rau kom muab tau bandwidth ntawm 28,8 GB / s.

Zog efficiency. Switching. Xyuas thiab cov nqi

Forte architecture Maxwell, uas underlies cov GeForce GTX 745 yog lub zog efficiency. Nws TDP yog tsuas yog siv rau 55W, thiab qhov no tso cai rau nws tsis muaj ntxiv cords muab hwj chim adapter. Tsis tas li ntawd, lub txias system, txawm hais tias active, tab sis yuav siv sij hawm li tsuas yog ib qhov, xws li nws yog sufficiently compact. Qhov no board yog tsim los muab ntsia nyob rau hauv lub PCI E qhov ntawm lub motherboard los ntawm 16X. Tso zis ports ntawm peb graphics: VGA, DVI, thiab, ntawm chav kawm, HDMI. Lub xeev kev txhawb xws li ib adapter yuav tau muas rau 60-75 dollars, thiab nyob rau hauv lub tshiab lub xeev nws tsis tau yuav. Zog efficiency thiab tus nqi qis - nws txawj GeForce GTX 745. Xyuas faib xws cons nws: nruab nrab kev kawm thiab lub cev tsis mus yuav hauv kiab khw.

tau

Zoo kuas duab daws yog cov GeForce GTX 745. Nws yog feem ntau zoo tagnrho rau cov nkag-qib gaming tshuab. Nyob rau tej kev kho vajtse yuav feem ntau ntawm cov khoom ua si, tsis tsuas yog nyob rau high chaw. Tab sis xav tias yuav tus nqi nws yog ib zajlus kom.
