Qualcomm Adreno 305: features, kuita, wongororo

Chii Qualcomm Adreno 305, vashoma vanoziva. Uye kunyange vaya vane zvimwe chinotiudza chii ichi chinhu ndechokuti, havasi kunzwisisa chii chaiva kuti. Kubva nguva muupenyu hwedu kusvimha akangwara phones, aifanira kukurumidza kutsvaka nzira kuva shoma hurongwa. Saka paiva foni processors uye zviduku Graphics accelerators.

Chii?

Saka, munhu Graphics processor, izvo kwete PC, asiwo "akagara pasi" iri edu okuvaka mano, kuzvigona dzinoitwa matambudziko. Ndivanaani rakajairika:

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

Ndiwo zvikuru nevanhu makambani kuti kare nekusimba kugadzikana uye kuita mhiri smartphones uye mahwendefa. Tisati zvokuongorora Adreno 305, zvinokosha kunzwisisa chii parameters vanoonekwa ne processors akadaro.

Saka, kunzwisisa chii tinosangana Graphics akisarareta, uye kutaura chinhu pamusoro mabasa ake, unofanira kutarisa zvitatu:

• Kuwanda zvokuridza por wechipiri.
• Kuwanda pixels por wechipiri.
• Kuwanda zvinoyangarara pfungwa kwacho.

Chokwadi, kuti vose mashoko inogona vakaongorora bedzi unyanzvi. Paavhareji mushandisi vachati kuti zvishoma nhamba iri parameters izvi. Saka ngationei kuwana kodzero zvakananga edu okuvaka womuenzaniso Adreno 305.

kambani iyi yakatanga vanopfuura mumwe Mobile processor. Somuenzaniso, smartphones zhinji anozvikudza wokuva mumwe mhuri Snapdragon pakati yokutevedzera. The mutsetse rakagadzirirwa smartphones uye mahwendefa, zviri kushanda pamwe ruoko mapurani, uye kutaurirana modules. Zviri izvi Mobile enyika ari Chip chitoro ane chipset, iyo inoreva gamba kuti kwataita.

Kazhinji, Snapdragon chinopiwa zviviri series, okutanga akagamuchira maindex S1 / S2 / S3 / S4, uye wechipiri - 2xx / 4xx / 6xx / 8xx. Raiva akatevedzana wechipiri Adreno 305. Zviri "yakavanzwa" mumhuri Snapdragon 400 uye kwave kune vakawanda okunatsiridza.

Kazhinji, vaya vanotanga kunzwisisa muenzaniso processor, chipset, moyo, platforms uye zvimwe zvinhu, uye pakarepo kucherechedza tsvina minimini. mhuri iyi Rinomiririrwa kwete imwe mhando. Pane shanduro dzakati siyana architectures, cores uye frequencies. Asi chikuru, mumwe nomumwe wavo hwakajeka 305-fung neerekitironi. Zviri kwose, uye naizvozvo, vanoratidza chisarudzo nguva dzose chete - 1280x800.

utsva

Muenzaniso yokutanga "adrenergic" 305 vakagamuchira nhamba 8225. The chipset rakaitirwa 28 nm muitiro michina ine pasi simba michina. Processor akava Cortex-A7 pamusoro cores mana chete kakawanda 1200MHz. Graphics akisarareta anotsigira zvakawanda Wireless kwokubatana: unopinza, Makaralı, Wi-Fi, GSM, HSPA + uye GPRS. pfungwa iyi rakasimba zhinji mudziyo yokutevedzera, ramakagadzwa - ari Samsung Galaxy ari S5, iyo S3 uye Tab 4, Sony Xperia M2, uye Microsoft ari lumia 640 XL.

Zvinotevera nadzurudzo iri anenge akauya asina kuchinja unhu kushandura Adreno chete 305. CPU kakawanda kubva 1,2 GHz kusvika 1,4 GHz, uye akisarareta vakaenda Samsung Galaxy S3 SS.

kuchinja

Chechitatu shanduro chipset aizivikanwa rechina chikamu 2013. Panguva iyoyo akatanga vakawanda kugadzirwa. mano akawedzera kuti pamazita mana Nokia lumia mienzaniso chipset akatanga kushandiswa mune yemashoko smartphones Huawei, HTC uye Acer. The hwokugadzira zvinoriumba dzinoshandurwa zvakare zvishoma. Vakadzoka kakawanda 1,2 GHz, uye yoku- mazita Wireless network kutsigira: DC-HSPA + uye LTE. A ano ndangariro uye chinogadzirwa panguva LPDDR2 LPDDR3.

Kuchikuva itsva

Zvinotevera nadzurudzo pamusoro chipset kwakaita kuti zvinhu zviri. Saka, Quad Cortex-A7 kuchatsiviwa Dual Krait 200 ine kakawanda 1.2-1.4 GHz. Pane mashoko ari bhuku rokutanga chechetere cache 32 KB, wechipiri - 1 MB. Ndiwedzere kuyeuka kwemichina. Mumakore mana shanduro processor kuchinja kuti Krait 300 uye unoshanda ari kakawanda 1700 MHz. Muchiitiko chino, nguva imwe neimwe mazita mano kuti vashande pamwe chipset, yakawedzera 3-5 yokutevedzera.

kuenzanisa

Enzanisa pamwe Adreno 305 Adreno 225 - rakajairika. Izvi imhaka yokuti mukuru shanduro iri kuenderera yomuduku. Kutaura zvazviri, 305-fung womuenzaniso - ichi update 225th. Iye pakutanga akazviratidza muna Snapdragon S4 Pro, asi kubudirira mukuru kubudirira mumhuri Snapdragon 400. The musiyano utsva yacho modernity. It rinotsigira nhamba huru michina mitsva, zviri nyore kutsungirira API, Direct3D 9.3, OpenGL ES 3.0 uye CL 1,2.

yokuedzwa

Performance Adreno 305 anogona chete achasimbiswa ne nemiedzo. Chokwadi, zvakawanda zvinoenderana chii papuratifomu vakaisa chipset uye processor akunoita pamwe chete. Core wachi maitikiro rinosvika 450 MHz. Parameter flops uri mukati 0.02 uye rinoratidza GPU kubudiswa simba processor.

0,8 GPixel / s - ndiko kumhanya ari pixels. parameter ichi kuwanda pixels inoratidzwa pasekondi yoga yoga. Sezvambotaurwa, muenzaniso zvinotsigira 9.3 shanduro DirectX, izvo yekudyidzana anovandudza Graphics mumitambo. Version of OpenCL 1,1 - iri zvemichina kuti anobvumira vamwe Software kushandisa Graphics akisarareta vasiri graphical zvinangwa.

TechProcess tsanga - 28 nm. Tichienzanisa pre-ano shanduro ndiyo huru mufananidzo, asi 2013 zvakanga echimurenga chipset miganhu.

Features

Adreno 305 - iri rakanaka vhidhiyo processor, rwakazokura yakakurumbira 2013. Panguva iyoyo Mobile mano vava nokukurumidza vakapakata muenzaniso uyu. Akagamuchira rakabatana shader mapurani. Paavhareji vhidhiyo kakawanda rinosvika 266 MHz, asi chaizvoizvo vaizivikanwa nechekare kusimudza kusvika 450 MHz.

The chipset ane chete core. Memory kushandiswa rinosvika 256 MB. Inside maviri shader kubudiswa pixels, mumwe geometry processor uye vertex shaders. Performance rinosvika mamiriyoni 98 zvokuridza por wechipiri uye mabhiriyoni 2,5 pixels munguva imwe chete.

Adreno 305 anogona kuitisa tessellation Hardware ukashanda zvizere-screen Anti-aliasing mufananidzo, rwokuyera-dimensional matatu pachiitiko pamusoro usina kukonekita, kuvheneka pave Hardware anoshanda Alpha Blanding uye akagamuchira Z buffer pamwe 24-wedzeredzei. Zvino kupfuura 50 akangwara dzeserura uye mahwendefa ane gumi basa izvi Graphics akisarareta. Vazhinji midziyo kubva kugadzirwa.

Reviews

Qualcomm yave kushanda kwenguva refu nguva GPU Adreno. The shanduro yokutanga yakatanga kuonekwa muna 2009 uye akanga atora kare pamusoro pamusika uye vanoshandisa kutarisirwa. Zvino pane processors manomwe ichi Graphics akisarareta. Kazhinji, havaiti kwakasiyana nepedyo. Dzimwe nguva kuoneka vibration frequencies.

Kune vachiri vanhu vane akangwara dzeserura pamwe Adreno 305. Reviews vhidhiyo processor iri diki zvakawanda. It anokonzerwa chokwadi chokuti chinhu chinokosha pamusoro foni, saka awana smartphone nezvaro, pane ayo nomumwe zvinoriumba.

Zvinozivikanwa kuti muenzaniso 2013, iyo vakagamuchira chipset zvinoreva avhareji mutengo chidimbu, uye akaratidza yakatsiga chaitwa, izvo haana anobuda chinhu chinokosha. Processors iri makirisito vakashanda zvakanaka, nemhaka simba kusendama nzira kuchengetedza kuzvionera kuti mudziyo kwenguva refu.

The chikuru zvakaipira kutenga mudziyo akadaro anonzi kuti inodzidzisa anogona kuteerera Snapdragon 400 yakawanikwa paIndaneti nokurondedzerwa, ongorora zvose uye aritore. Asi chokwadi Zvakazoitika kuti chipset iri zvishoma kudzikira mune zvimwe zviitiko kutendeukira kuna bvunzo kutadza. matambudziko aya anokonzerwa chokwadi kuti uone Snapdragon 400 aigona kazhinji kureva okunatsiridza shoma, iyo, kunyange aiva Adreno 305, zvimwe zviratidzo aigona zvakasiyana-siyana.

Yose zvayo, nyika Graphics zvakanaka. Akanga asina kudhonzwa matoyi chinoshamisira, asi pasi pazviruva kutsungirira zvinenge mabasa ose "Play Store". The chikuru drawback pamusoro Graphics uye processors kubva Qualcomm vaiona overheating nhasi. Saka zvino, vazhinji foni vagadziri kuramba zvivezwa ichi kambani uye kupa kupfuura Mali.
