Qualcomm Adreno 305: omsebenzi osemqoka, ukusebenza, ncomo

Yintoni Adreno Qualcomm 305, bambalwa uyazi. Kwaye nkqu nabo banayo ebesithini le nto, musa akusoloko ukuqonda ukuba yintoni na. Ukususela mzuzu ebomini bethu baziphalaza smart phones, kwafuneka ukuba ukukhangela ngokukhawuleza iindlela ukuphuhlisa inkqubo lifinyele. Ngoko kwakukho iziqhubekisi mobile kunye accelerators imizobo ezincinane.

Yintoni na?

Ngaloo ndlela, a njengomqhubekisi indlela yemizobo, nto leyo kuphela PC, kodwa "wahlala phantsi" kwizixhobo zethu mobile, uhlangabezana njani nale mingeni owayephila. Ngoobani aba common kakhulu:

• PowerVR;
• Mali;
• Adreno;
• GeForce ULP.

Le iinkampani kakhulu zithandwa esele ubungqina bokuba uzinzo kunye nokusebenza liphela Smartphones kunye namacwecwe. Phambi kokuqwalasela Adreno 305, kubalulekile ukuqonda oko parameters luphawulwa Processors ezinjalo.

parameters

Ngoko ke, ukuze uqonde into esijamelana nazo namafutha imizobo, yaye ukuba athethe into malunga umsebenzi wakhe, kufuneka ujonge ezintathu:

• Inani zoonxantathu ngomzuzu.
• Inani pixels ngomzuzu.
• Inani lencopho imisebenzi ngongoma.

Kakade ke, ukuba lonke ulwazi zihlalutywe kuphela ziingcali. Umsebenzisi avareji iya kuthi ukuba amanani omncinane kwezi parameters. Ngoko ke unelungelo ngqo imodeli yethu mobile Adreno 305.

Le nkampani iye yaphuhliswa kumqhubekekisi ngaphezu kwesinye mobile. Ngokomzekelo, Smartphones ezininzi liyi yokuba omnye Snapdragon usapho imifuziselo. Umgca yenzelwe Smartphones nezidanga, ukuba usebenza izakhiwo ARM, kunye neemodyuli zonxibelelwano. Kuyinto le nkqubo mobile kwi ivenkile chip a chipset, apho elibhekisela iqhawe ngokutsha wethu.

Ngokubanzi, i-Snapdragon linikwa kwi series ezimbini, ngolokuqala elithole nezalathiso S1 / S2 / S3 / S4, kwaye eyesibini - 2xx / 4xx / 6xx / 8xx. Yaba oluthi lesibini Adreno 305. Kuyinto "ezifihliweyo" kwintsapho Snapdragon 400 kwaye sele thaca ngayo zokuguqulwa.

Snapdragon 400

Ngokuqhelekileyo, abo baqala ukuqonda imodeli kumqhubekekisi, chipset, core, amaqonga kunye nezinye izinto, nangoko uya kuqaphela iqhinga emdaka. Le ntsapho imelwe hayi lwenkqubo. Kukho iinguqulelo eziliqela kunye lwazi bolwakhiwo lwempahla ezahlukeneyo, umphakathi kunye ezitsho. Nakuba kunjalo, ngamnye kubo inucleus graphic 305-th. Kuba bonke, yaye ngoko, isisombululo ukubonisa ihlale ifana - 1280x800.

izinto ezintsha

Umfuziselo lokuqala "adrenergic" 305 wafumana inani 8225. Le chipset senziwe kwi inkqubo 28 NM ubugcisa kunye nobugcisa ngamandla eliphantsi. Iprosesa waba neuron-A7 kwi umphakathi amane rhoqo ka 1200 MHz. Graphics namafutha ixhasa uluhlu imishini esebenza: EDGE, Bluetooth, Wi-Fi, GSM, HSPA + kunye GPRS. Olu khetho liqinile imifuziselo isixhobo abaninzi, ekuthe phakathi kwawo - i Samsung Galaxy i S5, i S3 kunye Tab 4, Sony Xperia M2, kwaye Microsoft i Lumia 640 XL.

Ukuguqulwa kulandelayo phantse wazisa akukho lutshintsho iimpawu ukutshintsha Adreno kuphela 305. CPU frequency ukusuka 1.2 GHz ukuya 1.4 GHz, kunye namafutha waya Samsung Galaxy S3 SS.

utshintsho

Inguqulelo yesithathu chipset yayisaziwa kwikota yesine ka-2013. Kwaba ngoko ukuba yaqala imveliso mass. Izixhobo yongezwe kuluhlu amane Nokia Lumia iimodeli chipset baqalisa kusetyenziswa imifuziselo Smartphones Huawei, HTC kunye Acer. Icandelo technical itshintswa kwakhona kancinci. esasidla Kwabuya 1.2 GHz, kwaye uluhlu oluhlaziyiweyo iinethiwekhi ze-wireless axhasayo: DC-HSPA + ne lte. A technology memory kwaye adluliselwa i LPDDR2 LPDDR3.

Inkundla entsha

Ukuguqulwa ilandelayo chipset zikhokelele utshintsho esisiseko. Ngenxa yoko, quad uthinte-A7 ithathwa yi Krait ezimbini 200 ene-rhoqo 1.2-1.4 GHz. Kukho data kwi lesixa cache kwinqanaba lokuqala 32 KB, okwesibini - 1 MB. Ukuphucula ubuchwepheshe memory. Kwinguqulelo emine edlulileyo utshintsho iprosesa ukuba Krait 300 kwaye isebenza kumaza ka 1700 MHz e. Kulo mzekelo, sihlandlo ngasinye noluhlu izixhobo ezisebenza kunye chipset, banda imifuziselo 3-5.

uthelekiso

Thelekisa ne Adreno 305 Adreno 225 - i ixhaphakileyo. Oku kungenxa yokuba inguqulo endala yi nokuqhubekeka mncinane. Enyanisweni, imodeli 305-th - eli update 225th. Yena kuqala ukuvela kwi Snapdragon S4 Pro, kodwa impumelelo enkulu afunyenwe kusapho Snapdragon 400 ezintsha umahluko ilele modernity yayo. Ixhasa inani elikhulu zobuchwepheshe obutsha, kulula ukumelana API, Direct3D 9.3, OpenGL ES 3.0 kunye CL 1.2.

uvavanyo

Performance Adreno 305 ibenako ukungqinisiswa kuphela iimvavanyo. Kambe ke, oku kuxhomekeke koko eqongeni obekwe chipset kunye iprosesa esebenza ngayo kunye. Core clock frequency ifikelela 450 MHz. flops Ipharamitha ungaphakathi 0,02 kwaye ibonisa amandla GPU processing of kumqhubekekisi.

0,8 GPixel / s - ke isantya pixels. Le parameter kugqiba inani pixels eboniswa ngomzuzwana. Njengoko kuchaziwe ngaphambili, imodeli ixhasa 9.3 inguqulelo ye iDirectX, nto leyo iphucula kakhulu ngemizobo imidlalo. Version of OpenCL 1.1 - yinto iteknoloji evumela ezinye software ukusebenzisa namafutha yemizobo iinjongo non-mfanekiso.

TechProcess kernel - 28 NM. Ethelekiswa version pre-mihla oyintsobi elikhulu, kodwa ngowama-2013 kwaba imilinganiselo chipset olululo.

iimpawu

Adreno 305 - oku umqhubekekisi ividiyo elungileyo, eyaba ethandwayo ngo-2013. Kungelo xesha olwenziwa zizixhobo eziphathwayo sele ngokukhawuleza zixhotyiswe nale modeli. Yena ufumana shader bokwakha emanyeneyo. Kwi-avareji amaza ividiyo ifikelela 266 MHz, kodwa eneneni ayesaziwa sele ngokuvusa ukuya ku 450 MHz.

Le chipset sele engundoqo enye. Ukusebenzisa Inkumbulo ifikelela-256 MB. Ngaphakathi pixels processing shader ezimbini, enye geometry iprosesa kunye shaders enekona. Performance ifikelela oonxantathu million 98 ngomzuzwana kunye pixels 2.5 billion kweli xesha linye.

Adreno 305 ukuze aqhube tessellation yentsimbi usebenza nge full-screen umfanekiso anti-olululo lobungakanani, yahlula umbono-onamacala amathathu tile, ukukhanyisa idala zekhompyutha isebenza alpha Blanding waza wafumana Z buffer kunye bit-24. Ngoku ngaphezulu kwama-50 phones smart kunye namacwecwe kunye nomsebenzi kweshumi nezi namafutha mifanekiso. Uninzi izixhobo ngaphandle kwemveliso.

Qualcomm sele usebenza ixesha elide kunye GPU Adreno. Iinguqulelo yokuqala ukuvela ngo-2009 kwaye sele wangena ezihlangwini emarikeni kunye abasebenzisi ingqalelo. Ngoku kukho iziqhubekisi ezisixhenxe nale namafutha mifanekiso. Ngokubanzi, ukuba akukho kwahluka enye kwenye. Ngamanye amaxesha amaza lokungcangcazela buqapheleke.

Kukho abantu abaye smart phones kunye Adreno 305. Ukuphonononga kumqhubekekisi ividiyo hi mpimo lowutsongo. Oku kubangelwa yinto yokuba yinxalenye ebalulekileyo ifowuni ephathwayo, ngoko ke ufumana i-ncomo smart, kunokuba amabakala alo ngamnye.

Yinto eyaziwayo ukuba umfuziselo 2013, elithole chipset ibhekisa kumndilili kwicandelo ixabiso, waza wabonisa yokusebenza ezinzileyo, nto leyo engazange avelile into ekhethekileyo. Iziqhubekisi nalo ezingundoqo asebenza kakuhle, sibulela amandla nobuchule Idla ukulondoloza ukuzimela kwefowuni ixesha elide.

Luncedo xa uthenga isixhobo eso kucingwa ukuba umsebenzisi ahlawule ingqalelo Snapdragon 400 afumaneka kwi ngokwenkcukacha Internet, ukuhlola konke nokuwenza. Kodwa enyanisweni kwenzeka ukuba chipset thile buthathaka kwezinye iimeko Tyhila ukuba ukusilela uvavanyo. Ezi neengxaki ezibangelwa kukuba a Snapdragon emfutshane 400 kusoloko kuthetha kokulungiswa embalwa, leyo, nangona Adreno 305, neminye imiqondiso ukuba ziyahluka kakhulu.

Ngokubanzi, yaba kwimizobo elungileyo. Wayengazi banduluka zokudlala ezintle, kodwa izicwangciso ezisezantsi ukumelana nazo phantse zonke iiprojekthi ze "Play Store". Eyona ethile engundoqo yemizobo iziqhubekisi ukusuka Qualcomm ingqalelo nobushushu namhlanje. Ngoko ke, abenzi abaninzi isixhobo mobile bayala iimveliso yale nkampani kwaye bakhethe Mali.
