Kungani ikhadi basking

Kwabanye abanini iikhompyutha lobuqu sisityhilelo ngokwenene into yokuba nayiphi na ikhadi yemizobo kumo, zombini ezahlukene kanti edibeneyo chipset okanye CPU.

Kutheni le nto isenzeka? Ngesizathu esithile, ikhadi ividiyo isebenza kupholile? Zonke sichazwe kakhulu nje: isiseko yevidiyo kumqhubekekisi yemizobo mihla ubunjwe izigidi yezitshixo elektroniki - transistors. Nangona ukusetyenziswa yangoku nganye kuzo ayinamsebenzi, ixabiso lilonke wayo omkhulu kakhulu.

Njengoko sisazi kwikhondo physics, indlela ezikhoyo umqhubi yi ukunyuka kwamaqondo obushushu le yokugqibela. Isiphumo livela kakhulu ngokucacileyo ngakumbi kwi ezitsho eziphakamileyo, nto leyo ethatha indawo amakhadi. Oku baqa- kuphela ngokusebenzisa superconductors kwi zero epheleleyo.

Ngoko ke, ukuba ikhadi ividiyo eshushu, oko akubonisi nandzu.

Noko ke, ngokufuthi kakhulu ukubuzwa iiforam esi sihloko. Kutheni isihloko ngokubanzi kuxoxwa? Isizathu soku kukuba khadi elibaselwe ngumoji ngamanye amaxesha ngamandla kakhulu, Unandawoni umnini computer.

Nge eyakhelwe-ngaphakathi CPU iintlobo akukho ngxaki - omkhulu mihla injini ngokulula uthothe ngaphezulu kwe-100 watts igunya thermal, nto leyo ngaphezu ngokwaneleyo. Ngaphandle ngesantya zawo izihlandlo eziliqela ivelisa wombukeli-class amaqhoshana obubobu, ngoko ke nezihlandlo ukusebenza kunye nenani transistors ayilingene ukudala umthwalo omkhulu kunene ukusebenza kwenkqubo sokupholisa. Ngamanye amazwi, amaxesha amaninzi basks ikhadi yangaphandle, pluggable ukuya kwisokethi motherboard.

Enye le mibuzo enzima ukuba ayikwazi uphendulwe ngqo oku: "Yintoni na ke ubushushu ikhadi levidiyo uthathwa ukuba eqhelekileyo?". Ngaba kuphela kalukhuni ukugqiba ubushushu avumelekile. Simse - yiya kwi website kumenzi GPU kaThixo (hayi onke amakhadi yokuzonwabisa) kunye nenkcazelo modeli ethile ukufumana ixabiso lobushushu avumelekile. Ngoko kuyimfuneko ukuba luthathele ingqalelo ukuba ezikhoyo iteknoloji ukulungiselela ukuveliswa kwe transistors semiconductor akakwazi ukwenza ezimbini ngokupheleleyo twatse, ngoko amaqela kusoloko ke ube "agcwayele" parameter elincinane,, ngaphakathi lunganako ukungagqibeleli. Oku kukhokelela ekubeni ikhadi omnye kuqhubeka ukusebenza kwi degrees 70, kwaye enye efanayo, kuphela 60 Kungenxa yoko le nto, ukuba ikhadi eshushu, abanini ngokufuthi ukubonisa iindidi lobushushu amakhadi abo kumqolo kwimveliso. Xa kungekho ndawo nomvelisi data zokufudumeza vumelwano - ukufunda abasebenzisi 3-4 ibhengeze amaxabiso uze ubale umlinganiselo. Ukuba izicelo 'enzima "-ntathu (umdlalo computer) ukufudumeza awudluli degrees 70, akukho sizathu inkxalabo.

Ubangelwa lobushushu kuvuka ezimbalwa:

- ungcoliseko ikhadi levidiyo bubushushu echibini uthuli. Isibakala sokuba zonke iinxalenye computer kufuneka zihlanjwe ngothuli amaxesha 2-3 ngonyaka ngamnye, kodwa lo mthetho kunqabile ukuba - kungakho ingxaki;

- ifeni yokupholisa siyeka (ukuba ikhona);

- ukungafani ekhutshwe yombane umbane ofunekayo amaxabiso. iiyunithi umbane ikhompyutha cheap kufuneka itshintshwe rhoqo kwiminyaka 1-2, ngenxa yemida yabo libya ngokuhamba kwexesha kuqala ku "edadayo", ukuphazamisa ukusebenza onke amacandelo;

- omiswe of i Cola thermal. Phakathi kumphezulu kumqhubekekisi yemizobo kunye heatsink kukho imeko-bume eliphakathi - paste thermal. Ekuhambeni kwexesha, ithe iimpawu zalo kwaye kufuneka kufakwe;

- ukungasebenzi kwesixhobo sekhompyutha le ikhadi levidiyo. eqhelekileyo - capacitor idumbile electrolytic. Kwakhona, ezinye iimodeli kwinkampani nVidia (umzekelo, i-9600 GT) waduma ngenxa yokuba emva konyaka okanye imilenze emibini ezaphukileyo soldered iprosesa, lwafumana imiphumo engalindelekanga - ukusuka ukunyuka kwamaqondo obushushu, ukugqiba ukusilela chip;

- sizathu ecaca - Kusasazwa ephosakeleyo yokumpompoza lomoya ngaphakathi kwinkqubo. Ukuba inkqubo iyunithi ukuze ususe isiciko kwicala ubushushu ihlala phakathi uluhlu elamkelekileyo, kufuneka ucinge malunga fans ezongezelelweyo.
