The Radeon 7770: zvinhu uye wongororo

Game Graphics adhaputa "nomwe nomwe vatatu" kubvira AMD kunzwa ose mafeni kuridza kukumikidza zvekuvaka-nyanyisa mitambo. By nezvekutanga ari Radeon 7770, ari mugadziri akaita chihombe danho kune munhu waunoda mutengi - akapa High-End mudziyo kirasi inokwanisika mutengo (8000 rubles) uye akaisa muna akisarareta bhajeti niche, zvishoma vakaomerwa unongotaura kwayo. Pfungwa yacho - kudzokorora vhidhiyo kadhi kuita, kudzidza zvinhu kubva vagadziri siyana, uye wongororo vazvo.

Two hama-Acrobat

AMD Radeon Graphics kadhi HD 7770 Series akaenda sale, pamwe ake udeshevlonnoy nadzurudzo HD 7750. Producer aida, saka pamwe chete GPU kutora mbiri dzakasiyana mutengo kirasi. Zvisinei, mutsauko chinokosha chokupika maviri Graphics makadhi uye musiyano duku mutengo zvakakonzera chokwadi kuti serisina nadzurudzo rakada isina musika kudiwa.

Zvino Radeon HD 7770 aigona rwakaonekwa kana kwete vhidhiyo kadhi vagadziri, uyo akaona guru zvinogona ari mudziyo kuti kumhanyisa, yekudyidzana kunowedzera mavhidhiyo waivako, ikasara kune High-End pamwero. Low simba zvinodyiwa uye vakadzikama kutonhora gadziriro sezvo nguva dzose kuvhuna zvinyorwa zvitsva mumunda uchitamba mutambo pamusika pasinei Graphics chinoumba uye kambani.

High waivako uchitamba mutambo Graphics kadhi inopa Radeon HD 7770 Graphics moyo unhu. Chip kugadzirwa ne Cape Verde 28 nanometer azoshandiswa rikurumidze uye akaisa bwendefa musi 123 mm ² uye transistors bhiriyoni nehafu. The itsva Graphics processor anokwanisa kushanda pane imwe kakawanda 1 GHz, uye achine zvinogona yokubudisa. Nokuti kuchinjwa mashoko anoenderana kuyeuka bhazi GDDR5, iyo inoshanda inokwana 128 matomu uye ane mungarava 1 gigabytes okuyeuka, kushanda panguva kakawanda 4500 MHz. Stream processor 640, unaku dzakabatana - 40.

Chimwe chikuru zviri mavhidhiyo kadhi iri pasi simba kuparadzwa - 80 watts or yepamusorosoro mitoro kuti panenge hafu kukura zvakafanana vakwikwidzi kubva Nvidia mugadziri. Uyewo pana Cape Verde Chip akatasva controller iyo resets kushoma kakawanda panguva simbe Video nemakadhi. Muzviitiko zvakadaro, simba rakawanda richava pamusoro 3 watts or.

Kujairirana chepakutanga

External Graphics kadhi AMD Radeon HD 7770 chakafanana pamusoro mudziyo. The nadzurudzo inoshanda kuti cheap car insurance maviri munyika Unit, uye unodzivirira casing ane kutonhora gadziriro rinotungamirirwa wokufema pcb. Kazhinji, kunenge kuti vhidhiyo kadhi uye kutonhora kwedzimba zviri unitary kuvakwa. Zvisinei, sezvataurwa munyaya yake review, vanoshandisa aipokana kutonhora rwuri kuti mune namahwindo casing anoiswa mukati bhodhi uye haana turbine - nayo chete yozodzokera redhiyeta. Yokururamisa neshungu mhepo chinowedzera huru kufefetedza grille, izvo inoremekedzwa chikamu yose mumwe fastening ndiro.

Chero mibvunzo kuti mugadziri varidzi monitors vekare, izvo zvinowanikwa pamusoro Graphics kadhi digitaalinen chete mavhidhiyo outputs (nokuti Mini DisplayPort, HDMI uye DVI). Pretty chinoshamisa mutongi zvakajeka akaderedza kufarira vhidhiyo kadhi iri Russian musika kombiyuta.

Zvinogona kuti fekitari overclocking

Vasati vatanga adzidze mano inopiwa nevamwe vagadziri ari Graphics kadhi pamusika, unofanira kunzwisisa hwokugadzira nezvaanogona nezvezvinotaurwa mavhidhiyo kadhi Radeon HD 7770. Magadzirirwo kuwedzera kumhanya ari Graphics chinoumba pano pakutanga. Saka, muna muitiro kuedza vhidhiyo kadhi takakwanisa overclock kuti Graphics processor kusvika 1170 MHz, uye ndangariro - kusvika 6120 MHz. Zvisinei, nokuti ichi, zvakanga zvakakodzera kuti kurera voltage kubva 1,1 V kusvika 1,2 V. Ipapo vhidhiyo kadhi muoti rinoratidza mukuru pakusimba pasina chitarisiko zvinoratidza uye matambudziko nevatyairi.

Mibvunzo inodzidzisa ungasangana mureza kutonhora maitiro isingagoni kukurira basa. Panguva yokuedzwa, mheremhere dzinoshandisa zvachose chinofukidza basa No zvose munyika Unit, asi Graphics makirisito tembiricha pamwe madhigirii asingasviki 70 Celsius haana akadonha. Pachishandiswa data, zvinganzi vakagumisa kuti kusarudza anodiwa Graphics kadhi nzira vaibayira musika vanofanira kuisa kwete chete pane overclocking zvinogona asiwo vakadzikama kutonhora hurongwa.

The Radeon HD 7770 kutengeswa pasi nesafiri Logo, ane zvakakomba prerequisites kuva pamusoro mutengesi pamusoro chokuratidza kuti "mutengo-unhu." Chokwadi kuti akaiswa mukati kutengeka chidimbu, vatengi vacho vakawanda bhajeti mano, asi fekitari overclocking mabasa anoisa Graphics kadhi iri chete chechetere pamwe High-End namano. The default Graphics chinoumba clocked panguva 1150MHz uye kuyeuka overclocked kuna 5000 MHz.

Sezvo tsika inoratidza ichi mukana chakavanzika shure Graphics kadhi yakazara kutonhora gadziriro iri kuiswa muna sesafaya murabhoritari. Kuti tinoonga chihombe aruminiyamu redhiyeta, anofukidza yose akadhindwa redunhu puranga, uye kupisa yemhangura kuchinjirwa sepombi anoparadzirwa zvakanaka kudziyisa, mavhidhiyo kadhi hazvirevi overheat. mhepo kuparadzirwa chendangariro chaizvo imwe dzinoshandisa kuti akatasva kubva kumusoro pamusoro varindi.

The Radeon 7770 mugadziri ASUS ichaongororwa yakanakisisa tenga pamisika kuita namano. Chinhu chiri fekitari overclocked, kuti pasi pasi garandi ari mutengesi. The Graphics Musimboti iri kuipa nzira iri clocked pana 1170 MHz, uye ndangariro - 4600 MHz. Excellent zvabuda. Uyezve vachisimudza waivako isina zvainoreva, kunyange zvazvo ndakagadza kutonhora gadziriro prerequisites nekuti ndiye: yemhangura chinoumba, aruminiyamu redhiyeta, rokudzivirira epurasitiki casing rimwe chete feni.

Zvinokosha kucherechedza kuti muRussia pane chimwe inoonekwa HD 7770 Graphics kadhi, ine pamusoro-bhodhi 2 GB of RAM. The mugadziri haana kuita overclock kuti GPU uye kuyeuka bhazi, tichisiya kutapwa yemberi muridzi. Nokuti kutonhora zviri Graphics kadhi inoungana rakafanana yapfuura mudziyo kutonhora hurongwa, zvisinei, zviri kare vakapakata mafeni maviri simba. Somugumisiro, mashoko GPU kumhanyisa anonzwisisa kuti kakawanda 1200 MHz, uye ndangariro unoshanda stably nokuda 5000 MHz.

Mutungamiri Taiwan musika

Video kadhi inobva Radeon 7770 pamwe chete kana maviri gigabytes okuyeuka panguva chete mutengo chinoitirwa Taiwanese kambani Gigabyte musika. Mugadziri vose mano yakawedzera kakawanda pakati GPU, akagara kuruoko kumativi 1100 MHz, uye akamutsa kuyeuka kakawanda kusvikira 5000 MHz. Somugumisiro, tinopfuurira kumhanyisa yekushanda haashandi, dambudziko rose iri pakutanga kutonhora hurongwa.

The Radeon 7770, Kucherov nechipiriso rinozivikanwa mugadziri pamusika wokuRussia, zvinoita sokunge munhu mukuru-mugumo mudziyo. Mbiri huru feni pamusoro redhiyeta goko zvakajeka achafara zvose zvinogona vatengi. Zvisinei, hazvina zvakakodzera kuti kukurumidza, nokuti boka asarudza kuenda rumwe nzira: pachinzvimbo munhangemutange mabasa ikakanda mabikirwo vakunde kudzikama ichishanda. Uye kuti iye akakwanisa 100%, nokuti miedzo zvakafanana mano nokuimba uye mafeni kunyange yepamusoro mutoro hazvirevi pfuura 26 db (yakanyarara pane ruzha kubva mwero CPU unotonhorera).

The mugadziri haana kuita kumhanyisa uye zvinopa zvigadzirwa sokuvakira AMD. Zvisinei, izvi hazvirevi kuti unogona kukanganwa pamusoro kuwedzera yauinayo. Graphic kuratidzwa kadhi chinoumba anokwanisa kushandisa stably panguva kakawanda 1100 MHz, uye ndangariro - 5200 MHz, rinotarira zvinogamuchirika kwazvo kana ichienzaniswa vakwikwidzi. Varidzi vanoti vanokwanisa kumhanyisa aripo, asi dambudziko - iri kumhanya limiter unotonhorera, kana iwe bvisa izvozvo, unogona zvakachengeteka kuvandudza chokupika kusvika 1200 MHz pamusoro core.
