Bwanji khalidwe mu masewera?

Onse zitsanzo monga kuthandiza DirectX 11. Pamene msika anayamba kuoneka yobiriwira zithunzi khadi chitsanzo, panali pafupifupi kanthu pa zimene zikanatha kuyesa mphamvu ya chipangizo ichi, koma ndi kutulutsidwa kwa GeForce GTX 470 vuto sanasinthe. Games kuti akhoza kuthandiza watsopano API, kanalekanitsidwa milandu, koma m'kupita kwa nthawi, ndithudi, linaperekedwa ambiri ntchito zosiyanasiyana, omwe kugwiritsa ntchito vidiyo khadi. Ngakhale masiku ano ntchito yake ndi mulingo woyenera kuti ambiri a masewera, ndipo ngati atsopano sangathe idzaseweredwe pa zofunika pazipita, sing'anga, kapena osachepera izo kukhala m'khola.

Monga mwachizolowezi, kampani anaganiza kubetcherana mokomera m'tsogolo ndi optimizing wanu NVIDIA GeForce GTX 470 ntchito ndi nthawi imene anapereka lotsiriza la DirectX, komanso akupenyetsetsa kwa GPGPU.

Kamangidwe ka Chip zatsopano

The chipangizo latsopano ntchito Chip ndi ndi zomangamanga atsopano otchedwa GF100. Koyamba, panali kusiyana kwambiri kuchokera kuloŵedwa m'malo, kapangidwe ka zinthu zatsopano anakhalabe scalar, kotero kuti sangachite analipo. Pang'ono anasintha zikuchokera mapurosesa ambiri cholinga anaganiza zimagwirizizirana ndi midadada mwachilungamo lalikulu. Mu zitsanzo za GT200 mayunitsi amenewa amatchedwa TPC, ndipo aliyense wa iwo m'gulu la Chalk zofunikira zonse zina pamafunika pamene ntchito ndi zithunzi, kupatulapo midadada rasterization. M'tsogolo, kampani mwamsanga anayamba kupanga kwambiri Mabaibulo kubwereketsa wa NVIDIA GeForce GTX 470, kumene midadada amenewa anali mwina sakukhudzidwa kapena kusinthidwa.

Aliyense chipika zoterozo za m'mbuyomu chitsanzo Chip pano atatu SM (akukhamukira multiprocessors), ndi mayunitsi kapangidwe asanu ndi atatu oyamba mlingo posungira 16 KB. Mu chipika zipangizo atsopano, munthu Raster Engine lakhala likugwiritsidwa ntchito ndi anayi SM, aliyense amene alipo yekha posungira ndi kapangidwe mayunitsi. Pa Chip chomwecho, pali imodzi midadada anayi kuchuluka kupereka wosuta pixels 32 pa wotchi.

akukhamukira multiprocessors

Ngati tikambirana chipangizo pa mlingo wa SM, kusiyana ndi yofunika kwambiri, kuyambira pamene iye anali kumasulidwa ku NVIDIA GTX 470, akatswiri ambiri amanena kuti pali wokulirapo SM ndi palokha. M'mbuyomu, m'badwo pano khadi 8 SP, komanso 2 SFU, koma tsopano chiwerengero chawo ndi chiŵerengero anasintha, umene aliyense chipangizo analipo pa 4 SFU, 32 CUDA Kore, 16 Ndipo Katundu / Store mayunitsi.

Aliyense wa multiprocessors izi mbadwo wachitatu panali angapo mapurosesa kapangidwe ndi kukumbukira nawo kuti amapereka hardware tessellation.

Chifukwa chakuti kapangidwe mapurosesa, komanso zogwirizana multiprocessors onse posungira kukumbukira kuti mtima mkati, ndi kutukula anatha kukwaniritsa ntchito kwambiri zosavuta zipangizozi. Komanso anaganiza ukasintha rework Kamangidwe mkati mwa zipangizozi, kuonjezera pafupipafupi cha ntchito yawo, kuphatikiza katatu buku mlingo wachiwiri kukumbukira ntchito mwakhama ndondomeko ya texturing.

kukumbukira wamba

Nawo kukumbukira wakhala pamodzi ndi posungira L1, chifukwa mu lolingana kukumbukira amakhala bwino anagawira kutengera mtundu wa ntchito amachitidwa pa nthawi chipangizo. Poyamba kukumbukira wamba m'gulu okha 16 KB Koma pakadali pano, malingana ndi mtundu wa ntchito, zida adzakhala kugawira 64 KB kuiwalidwa. Ngati pa nthawi, ambiri kuthetsa thupi, ndiye 48 KB wa khadi kukumbukira GTX 470 kugawira kwa L1. Ngati njira zosiyanasiyana wambirimbiri nthawi kufufuza mfundo zimenezi, amasungidwa kukumbukira nawo. Mwa zina zothandiza GPGPU komanso katatu chiwerengero cha L2 posungira mu GTX 470. Mankhwala zofunika kwambiri koposa anapita patsogolo poyerekeza ndi mpikisano.

tessellation

Tessellation ndi chimodzi mwa zinthu zofunika kwambiri za khadi Radeon HD 5000. Video khadi NVIDIA GeForce GTX 470 Nayenso bwino pansi kukhazikitsa aligorivimu izi.

The API DirectX 11, pali thandizo kwa ena "mapu kusamutsidwa" amene mawonekedwe buku. Motero, aliyense mapikiselo ili mu chifanizo cha kapangidwe ka, adzaona msinkhu wake. kapangidwe Izi umagwiritsidwa ntchito masewero pofuna kupanga chifaniziro mwatsatanetsatane.

Apa ndi pamene abwera ku tessellation, amene okonzeka ndi GTX 470. mwachidule za aligorivimu inasonyeza kuti zithunzi lonse aumbike ku malo limodzi. Njira imeneyi ntchito mosasamala mapu kusamutsidwa, koma zotsatira yochititsa chidwi chingapezeke ngati ali ntchito pamodzi. Nsonga za kupanga polygons adzatsika kapena kukwera pamwamba, kubweretsa dongosolo chitsanzo mwachindunji ndi chipinda khadi.

ndi ubwino wotani?

Ndipotu chitsanzo analandira zofanana mwamtheradi muyezo pole mkulu, kunyalanyaza nthawi yomweyo, otsika pole, T. Kwa. Iwo adzakupatsani zazikulu lolondola ndi mthunzi molondola, kuthera Motero kuti onse ukulu zinthu zochepa.

M'mawu ena, NVIDIA GTX 470 makhalidwe kuti mwamsanga kutsegula ndi makadi chitsanzo kukumbukira, pamene ina simusowa kuchita potsegula ndi katundu maofesi ndi milingo ina ya mwatsatanetsatane, chimene chidali choona kwa zipangizo mbadwo wakale. njira zonse akutsatiridwa kutembenuza mwachindunji mkati khadi pa njira zosiyanasiyana zimene amapereka scalability kwambiri. Malinga pamaso pa ufulu wonse kompyuta mphamvu kudzakhala pafupi ndi mapu kusamutsidwa ndi lolondola ena, chimene chiri chofunika kwambiri mwa mawu a zojambula ntchito GTX 470. ndemanga wogwiritsa amati luso kwambiri bwino ntchito chachikulu kompyuta pa kuphedwa kwa njira zovuta zithunzi.

Kodi ogwiritsa mukunena?

Feedback kuchokera kwa ogwiritsa, kusintha kompyuta yanu ndi khazikitsa mapu anafotokoza zikusonyeza kuti pambuyo Mokweza ndi kotheka kuika mu masewera onse zoikamo pazipita. masewerawo sanali inaonongeka, palibe mabuleki sanali anati.

Kumene, mayankho awa ndi khalidwe la 2010-2012, pa mphindi khadi salinso amapereka mwiniwake ndi mwayi ngati wopandamalire. Koma pa luso nthawi ankadumphira patsogolo, ndi kupita nawo masewera izi, zimene ngati khadi zithunzi zitha idzaseweredwe pa zoikamo osachepera.

3D Masomphenya

luso 3D lero analandira ambiri kwambiri, kuyambira matelevizioni ndi oyang'anira mathero. Ngakhale kampani AMD kalekale ikupereka magalasi ake, komanso mapulogalamu, zimene zimathandiza kanema khadi wopanga kusonyeza apamwamba zithunzi stereoscopic.

The GeForce GTX 470 mbali mulinso luso logwiritsa ntchito njira imeneyi, ndipo ngakhale kuti ali ndi chidwi ntchito chonse amaona wa kosewera masewero kapena kanema ndi zosiyana kwathunthu.

Achikhalire lonse zipangizo operekedwa ndi makadi osiyana kanema ndi API, ndi yovuta mokwanira kuphunzira owerenga wamba motero akuti ndi achabechabe mwamtheradi ngati palibe m'modzi adzawona ntchito. Ndi chifukwa chake NVIDIA wakhala analenga kugawanika osiyana ntchito ndi kutukula ano masewera. Kumene, tcheru nthawi zonse kuti ntchito bwino kwambiri, umene unakhazikitsidwa mogwirizana ndi matanthauzo opindulitsa, chifukwa pamapeto pake masewera yokha chimakhala mofulumira ndi kokongola kwambiri kukachitika kuti ali anapezerapo wosuta pa kompyuta ndi khadili.

dongosolo kuzirala

Kuonetsetsa kuzirala okwanira, khadi kampani zachitika ndi ozizira apadera, yemwe ali mmodzi wa wamphamvu kwambiri mwa zitsanzo zofanana pakuyenerera. chipangizo lakonzedwa mu mawonekedwe a chopangira mphamvu muyezo, koma ali ndi zinthu zingapo kuti ndithudi kuliganizira wapadera.

Pamene dongosolo maziko kwa galimotoyo makina ndi chivundikiro pulasitiki Ufumuyo. Kudzera apadera yopuma ikukhudzana kutentha kwaiye pa ntchito tchipisi kukumbukira ndi subsystems, imafalikira ndi chimango lapansi. Kuchokera GF 100, kutentha kuchotsedwa mothandizidwa ndi mapaipi asanu wapadera kutentha amakhudzana ndi Chip mwachindunji.

Direct kukhudzana mipope kutentha Chip kawirikawiri amagwiritsidwa ntchito yozizira kachitidwe, mapurosesa, ndipo ngati dongosolo sitinganene kuti mwachionekere kwambiri kuposa muyezo. Koma mu nkhani iyi zikunenedwa kuti, pamene anakamba, ndi GeForce GTX 470, ndi kutukula tcheru wapadera dongosolo yozizira.
