Kodi HD 6670?

Radeon HD 6670 si chitsanzo asonyeza zakuti, ngati yaima sali mu malo oyamba mu masanjidwe ndipo pali zitsanzo wamphamvu kwambiri, monga HD 6790, ndipo ena. komiti iyi ndi Baibulo bajeti, anaikira makompyuta Masewero otsika mtengo, amene amalola kuthamanga chisanadze emptive ntchito zambiri zamakono mu sing'anga kapena zoikamo osachepera. Radeon HD 6670 ndi njira yabwino mtengo-amazindikira opanga masewera amene amakonda kupuma nthawi kuwayang'anira, koma musati kuthamangitsa zonse iliyonse zachilendo ndipo sindikufuna kuchita pa yako kompyuta "omnivorous" makina amene angathamange zonse pa izo anakhazikitsa.

Ngati poyamba ankaona chitsanzo m'njira, zonse mwakamodzi igwera mu malo. Radeon HD 6670 ndi zibwerere pakati pa awiri Mabaibulo a makadi zithunzi: matumizidwe ophatikizika amawu, nyimbo ndi zithunzi middling ndi accelerators Masewero weniweni. Kumene, ndi magulu osiyana kwambiri mankhwala, kuyambira yotsirizira amafuna apamwamba ntchito zotheka, pamene lachiwiri akhale chete, ndipo n'chifukwa miyeso yaying'ono, kuti athe adzaikidwa mu phukusi ka malo osiyanasiyana TV osati kumvutitsa Mwini mphekesera pa maholide.

Pa Mlengi chomwecho muyenera kuchita osakaniza makhalidwe onse zabwino ogula, kotero kuti kunapezeka wokongola chidwi khadi, kwambiri ndendende anaikira gulu yeniyeni ogula. Malinga ndi ndemanga, ngati inu muli munthu amene si nthawi zambiri kusewera osati kuthamangitsa ena zithunzi zapamwamba kwambiri zotsatira za Radeon HD 6670 - njira anu abwino.

zomangamanga

chitsanzo ichi anadutsa lonse miyezi 15 (HD 5570) pambuyo kuloŵedwa m'malo, umene ndi nyengo mwachilungamo kwambiri nthawi imeneyi. N'chifukwa chake poyamba ndi bwino kuganizira zimene zisinthe zachitika pomanga accelerator ndi monga Mlengi ndi anatha kuonjezera makhalidwe.

Mwakucimbidza Dziwani chakuti Radeon HD 6670 AMD anaganiza kuti kuchepetsa muyezo theka miyeso monga miyambo kutambasuka pafupipafupi. Choncho, mu m'badwo wotsiriza wa zithunzi khadi anaika Redwood GPU, pamene chitsanzo latsopano zachokera GPU Turkey. purosesa ichi poyamba pabwino ngati zatsopano, osati chabe kupereka ndi Baibulo kusinthidwa a ngale m'mbuyomu.

Mapurosesa zitsanzo yapita

Kukhala yokwanira bwino, icho chinali kugwiritsidwa ntchito pa yapita chitsanzo purosesa Redwood, ndi XT index, amene kumakumbukulidwa pa Mabaibulo akale a mapurosesa. Komanso chitsanzo ichi ndi pakati wakhalanso ntchito mu ndondomeko kupanga zitsanzo HD 5550 ndi HD 5570, koma pa nthawi yomweyo iwo kukhazikitsa chipangizo ndi index ovomereza. Kuyambira Baibulo wake wamkulu, Baibulo ili mwapadera yafupika pafupipafupi opaleshoni, pamene kusinthidwa zambiri junior Le adali nayenso chepetse chiwerengero cha yogwira mitima atilakwira.

Monga phata zapansi anali asanu likutipatsa mini SIMD masango, omwe m'gulu 16 akukhamukira Mipikisano ndondomeko. M'mawu ena, omwe lili asanu umodzi-mtsinje processing, ndi fanizo anasonyeza mwa AMD mu mndandanda wake wa thabwa ntchito. Aliyense limodzi nayenso ukugwira ndi midadada anayi kapangidwe.

Kodi kusiyana kwake?

Ndipotu, kunapezeka, moti pomalizira pake purosesa GPU Turkey ndi pafupifupi ofanana mu zomangamanga ndi chipangizo. Kapangidwe ka ntchito zawo ndi zayamba yemweyo, ndi chachikulu Pankhaniyi angatchedwe ndi ambiri SIMD-chipika zomangamanga ndi sidzasinthika, limene chiwerengero cha mapurosesa mtsinje anali m'thumba kuchuluka kwa 400 kwa 480. Komanso, anaimirira chiwerengero mayunitsi kapangidwe 20 mpaka 24, pamene rasterization chipika kasinthidwe ali yemweyo, ndipo manambala awo ali ofanana ndi 8 zidutswa.

Ndiko kusiyana konse, zomwe zimasonyeza kuti kompyuta gawo la ngale watha. Kukumbukira Mtsogoleri mu AMD Radeon HD 6670, monga mwa chitsanzo akale, kupereka uthenga GDDR5 tchipisi ndi pakati kudzera basi 128-bit, pamene zingwe za SIMD umisiri zotchinga ndi zonse zofanana. Dziwani chakuti pakati nazonso zida ndi zina opha Eyefinity, lomwe ndi wapadera Mlengi wa luso lakonzedwa kulumikiza ku khadi limodzi kwa oyang'anira angapo nthawi imodzi.

Ku mibadwomibadwo UVD khadi kanema wagawo akukumana wamakono pang'onopang'ono. Motero, Baibulo 2.0 polima mtundu thandizo MPEG-2, pamene kusintha kwa 2.2 kale mwasintha zazing'ono kuonetsetsa waphindu ndi wosavuta ntchito ndi codecs osiyana. Koma Radeon HD 6670, pa kafukufuku anasonyeza kuti latsopano chipika UVD 3,0 amatithandiza kuti MPEG-4 mamba, ndi kale anatha kuthandiza Blu-Ray 3D.

Popeza lalikulu kufanana yokwanira pakati Turkey ndi Redwood, chiwerengero cha transistors pa Chip wa chitsanzo latsopano wauka kwambiri - mpaka miliyoni 715 (pa mamiliyoni 627, kapena phindu 14%). Zonsezi zinachititsa kuti zimene komanso kuchuluka ndi dera la galasi loyambirira, lomwe tsopano ndi 118 mamilimita ² 110 mamilimita ² mmalo ^mwake, monga kale.

Ngati inu mukukhulupirira ndemanga, mu zomangamanga ndi Radeon HD 6670 si kutali kwambiri kuchotsedwa kuloŵedwa m'malo.

ndi ubwino wake chiyani?

Ngati ife kuganizira za ubwino chitsanzo ichi, Dziwani izi:

• chiwerengero cha mapurosesa mtsinje anali chinawonjezeka kuchoka mayunitsi 400 480, i.e. kuwonjezeka ndi 20% .;
• chiwerengero cha mayunitsi kapangidwe wakhala kuchuluka 20 mpaka 24, i.e. Pankhaniyi komanso kuwonjezeka ndi 20%;
• ngale zikugwira ntchito pafupipafupi alamuka 775 kwa 800 MHz (kuno kukula 3.2 okha%).

N'zoona kuti kusintha ngati sangathe adzatchedwa chosintha, kuti mukhale ntchito liwiro la chochitika kapena "masamu" duwa si noticeable kwambiri. Zabwino makokedwe mu nkhani iyi ndi kuti kuwonjezereka ntchito anali akwaniritsa ndi kuwonjezeka kochepa mu mowa mphamvu wawuka mwa yekha ena Watts 5. Monga mauniko, khadi iyi, ndipo pabwino monga Masewero accelerator, monga kuloŵedwa m'malo, zikhoza kugwiritsidwa ntchito popanda zingwe zoonjezera mphamvu ndi mfundo yofunika kwambiri kachitidwe lero ang'ono-kakulidwe.

chikumbukiro

Kukumbukira subsystem ndi kusintha onse amakhala aang'ono. Mu HD 5670 lachitsanzo ntchito GDDR3 tchipisi kapena GDDR5, pamene gawo loyamba si bwino kwambiri Baibulo, chifukwa zithunzi khadi mu namtindi wa milandu ankapulumutsidwa ku msika OEM, kumene kunali koyenera kuti abweretse makasitomala wosadziwa maina okweza. Mwachilungamo yopapatiza 128-bit basi si njira yabwino interacts ndi GDDR3 tchipisi mtundu, kuyambira bandiwifi 25 GB / s ndithudi sikokwanira kuonetsetsa ntchito wabwinobwino wa GPU kwenikweni zipatso. Pankhani ya ntchito GDDR5 vuto ndi kwambiri bwino, ndipo okwana mphamvu kale anamuukitsa kwa 64 GB / s.

zosinthika amagwiritsa ntchito lero khadi kanema AMD Radeon HD 6670, pamene kusinthidwa, zida ndi wosakwiya GDDR3 mtundu kukumbukira, akhala kwathunthu inathetsedwa. Makhalidwe pafupipafupi tchipisi ntchito pa zitsanzo onse ali ofanana ndi akupanga 4,000 MHz.

kuzirala

Ndithu n'zosadabwitsa, m'kati losavuta kutentha ntchito chipangizo ^pafupifupi 45 C, umene ndi chifukwa m'malo waukulu, popeza accelerator poyamba chimaoneka ntchito dongosolo chabwino kwambiri kuzirala. Pamene ntchito purosesa yogwira iyamba kusuntha kuchokera pansi-pafupipafupi mode zonse, ndi chimodzimodzi chimachitika ndi tchipisi kukumbukira chifukwa chake pamaso pa kutentha zimenezi.

Oika nkhawa (magazi mosaumilizidwa)

Mu kwambiri zinthu, kutentha 72 ^C, lomwe kale akuimira zotsatira zabwino kwambiri, makamaka poganizira kuti liwiro zimakupiza yekha pang'ono upambana 50% wa mtengo pazipita zotheka. Choncho, zithunzi khadi AMD Radeon HD 6670 ogwiritsa ndemanga amanena izo ziri chimodzimodzi zomwe si mkangano osati phokoso kwambiri pa ntchito ngakhale zipatso masewera ndi ntchito.

Ngakhale fani amakhala ndi awiri ka impeller ndi, n'zotheka mosavuta kanthu, ndi pa katundu kwambiri mlingo phokoso ndi DB 33,7 yekha. Kumene, sikutheka kuti khadi dzina chete, opereka ndemanga kuti inu mukhoza kumva izo bwino kwambiri.

analogs

Video khadi Radeon HD 6670 ali ndi makhalidwe zayamba mofanana chitsanzo cha HD 6570 lomwe ndi maliseche Baibulo ngakhale chitsanzo achikulire, koma ali pabwino chimodzimodzi. Zikatero, yomwenso chachikulu ndi pa n'kopindulitsa kwambiri kwa mtengo ogula ndi ntchito chipangizo.

GeForce GT 440

Komanso Dziwani kuti tidaipanga poyerekeza njira zawo, onse ndi kupikisana zitsanzo GeForce GT 440. Choncho, malinga ndi kuyezetsa pa masewera a nthawi chisankho ndi za 15-40% waphindu kutengera ndi inu kupereka zanu mmalo mwa mawu a masewera, zonse mwa mawu a zithunzi. Kuyenera ananena kuti, ngakhale ntchito bajeti mwa zipangizozi, adakhoza kuthamanga ngakhale kwambiri, wovuta kwambiri masewera a nthawi, lomwe kale akulankhula za chakuti ntchito zambiri zamakono, inunso athe kuthamanga osachepera zoikamo osachepera.

HD 6450

Ena ndemanga kunena kuti HD 6450 akufanana ndi Radeon HD 6670 ntchito, koma kwenikweni ndi chipangizo chosiyana. Choyamba ndi Dziwani mfundo kuti zachokera purosesa Caicos, lomwe makhalidwe ake pa katatu zosakwana zitsanzo achikulire, ngati iwo ali 160. okha amenewa chipangizo adzakhala okwanira mu mawu a mapurosesa mtsinje okha ena lophweka masewera, ndi chigamulocho otsika.

Pankhaniyi makhalidwe zikuyendera. Dziwani kuti poyerekeza ndi Radeon HD 6670 ndemanga akatswiri za chipangizo chimenechi zambiri taonera zambiri zimene mungachite zilipo, popeza ntchito mitundu yosiyanasiyana yokumbukira ndi pakati mafurikwense. Ngati ife kulankhula mwachindunji za zili mkati pogwiritsa, tikhoza kunena kuti chipangizo ndi zofanana mwamtheradi poyerekeza chitsanzo akulu, ndi kusiyana kokha kokha ntchito pakati pafupipafupi angatchedwe mu nkhani iyi.
