Qualcomm Adreno 305: āhuatanga, mahi, arotake

He aha te mea he Qualcomm Adreno 305, torutoru mohio. A ara te hunga e whai etahi clue aha tenei mea, ko te, e kore e matau i nga wa katoa te mea i reira hoki. Mai te kau i roto i to tatou oraraa pakaru ki waea atamai, i ki te titiro hohoro hoki huarahi ki te whakawhanake i tētahi pūnaha iti. Heoi i reira ko nga pūtukatuka pūkoro me accelerators whakairoiro iti.

He aha te mea te reira?

Ko te kupu, he pūtukatuka whakairoiro, i te mea e kore anake i roto i te PC, engari ano hoki "noho iho" i roto i to tatou whakaaro pūkoro, pakari ki te mau tamataraa o nāianei. Ko te noa tino wai:

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

Ko te kamupene tino rongonui e kua kï kua pūmautanga me te mahi puta noa i smartphones me papa tenei. I mua i whakaaro te Adreno 305, he mea e tika ana ki te matau ki ta tawhā e āhuatanga e taua pūtukatuka.

tawhā

Na, ki te matau ki ta tatou e fehangahangai whakatere whakairoiro, a ki te mea te tahi mea e pā ana ki tona mahi, e hiahia ana koe ki te titiro i ngā kōwhiringa e toru:

• Ko te maha o ngā tapatoru ia te rua.
• Ko te maha o pika ia te rua.
• Ko te maha o tere ngā mahi ira.

O te akoranga, e taea te tātarihia te mōhiohio katoa anake i tohunga. Ka mea te kaiwhakamahi toharite e nga whika iti i runga i enei tawhā. Na kia whiwhi tika tika a ki to matou tauira pūkoro Adreno 305.

Qualcomm

Kua whakawhanakehia tēnei kamupene neke atu i te kotahi pūtukatuka pūkoro. Hei tauira, ka taea e maha smartphones whakamanamana o he tetahi o te hapu Snapdragon o tauira. Kei te hangaia te aho mō smartphones me papa, kei te mahi i te reira ki te hoahoanga ARM, me kōwae kōrero. Ko enei pūnaha pūkoro i runga i te toa maramara he chipset, ki e pā ana te hero o to tatou arotake.

Ko te tikanga, te aroaro te Snapdragon te i roto i te raupapa e rua, riro te tuatahi o nei nga taupū S1 / S2 / S3 / S4, me te tuarua - 2xx / 4xx / 6xx / 8xx. Ko reira te rua te raupapa ko Adreno 305. Ko reira "huna" i roto i te utuafare Snapdragon 400 me kua aroaro ki pinepine o akatuke'anga.

Snapdragon 400

Ko te tikanga, te hunga e timata ana ki te matau i te tauira o te pūtukatuka, chipset, matua, tüäpapa me era atu mea, ka kite tonu i te whakapati paru. Kei te kore māngai tenei hapu i tauira kotahi. He maha ngā putanga ki rerekē architectures, otaota me iarere. Ko whānui, ko te karihi 305-th whakairoiro ia o ratou. Ko reira i roto i te katoa, a reira, ko te taumira whakaatu tonu te taua - 1280x800.

minamina ana

Ko te tauira tuatahi, ko te "adrenergic" 305 riro tau 8225. hanga te chipset i runga i te hangarau tukanga 28 nm ki te hangarau mana iti. ka pūtukatuka uho-A7 i wha otaota ki te auautanga o te 1200 MHz. tautoko whakairoiro whakatere i te whānuitanga o ngā hononga ahokore: Mata, Nihokikorangi, Wi-Fi, GSM, HSPA + me GPRS. noho ana tēnei kōwhiringa i roto i maha tauira pūrere, i roto i nei - te Samsung nga tupuni te g5, te S3 ko Ripa 4, Sony Xperia M2, me te Microsoft te Lumia 640 XL.

Kei te tata kawea te whakarerekētanga e whai ake nei kahore he huringa i roto i te āhuatanga huri anake Adreno 305. PTM auau i 1.2 GHz ki 1.4 GHz, a haere ana i te whakatere ki Samsung nga tupuni S3 SS.

huringa

mohiotia te putanga tuatoru o te chipset i roto i te hauwhā wha o 2013. Ko reira ka e timata te reira production papatipu. timata hoki ngā pūrere tāpiri ki te rārangi mā te wha Nokia Lumia tauira chipset ki te whakamahi i roto i te tauira o smartphones Huawei, HTC me Acer. ke ano te wae hangarau te paku. auau hoki o 1.2 GHz, me te rārangi whakahoutia o whatunga ahokore tautoko: DC-HSPA + ko LTE. tukatuka te hangarau mahara, me te i te LPDDR2 LPDDR3.

Ko te tüäpapa hou

Ko te whakarerekētanga e whai ake nei o te chipset i arahina ki huringa faufaa. Ko te kupu, whakakapia tapawhā uho-A7 e rua Krait 200 e kua te auau o 1.2-1.4 GH. He raraunga i runga i te rōrahi i roto i te keteroki taumata tuatahi 32 KB, te tuarua - 1 MB. Whakapai i te hangarau mahara. I roto i te huringa pūtukatuka putanga whakamutunga wha ki te Krait 300 me mahi i te auau o 1700 MHz. I roto i tenei take, te wā i ia te rārangi o ngā pūrere e mahi ki te chipset, nui haere e 3-5 tauira.

whakarite

Whakatauritea ki Adreno 305 Adreno 225 - te noa tino. Ko e tika ana ki te meka i te putanga tawhito ko te haere tonu o te whakaotinga tenei. I roto i te meka, te tauira 305-th - tenei whakahou 225th. Ia te tuatahi puta i roto i te Pro Snapdragon S4, engari te angitu nui tutuki i roto i te whānau Snapdragon 400. takoto te minamina ana rerekētanga i roto i tona hurihuri. E tautoko ana i te maha nui o hangarau hou, he mea ohie ki te akakoromaki i te API, Direct3D 9.3, OpenGL ES 3.0 me CL 1.2.

whakamātautau

Ka taea e anake Mahinga Adreno 305 kia mana aianei e whakamātautau. O te akoranga, nui i te mea ta turanga whakanohoia chipset me pūtukatuka pehea te mahi i te reira tahi. auau karaka Core tae 450 MHz. flops tawhā roto 0.02 me tohu mana tukatuka GPU o te pūtukatuka.

0.8 GPixel / s - ko te tere o te pika. Tenei tawhā whakatau te maha o pika e kua whakaaturia ia te rua. Ka rite ki whakahuatia mua, tautoko te tauira 9.3 putanga o DirectX, e tino whakapiki i te whakairoiro i roto i ngā kēmu. Putanga o OpenCL 1.1 - ko te hangarau e taea etahi pūmanawa ki te whakamahi i whakatere whakairoiro mō ngā take kore-kauwhata.

TechProcess pata - 28 nm. Ina whakaritea ki te putanga i mua i-hou ko te ahua nui, engari i te 2013 ko reira āhuatanga chipset orurehau.

āhuatanga

Adreno 305 - ko te pūtukatuka ataata pai, i meinga rongonui i roto i te 2013 tenei. Ko reira ka e kua riro whakaaro pūkoro tere rawa ki tenei tauira. riro ia te hoahoanga shader kotahi. I te toharite tae te auau ataata 266 MHz, engari mohiotia i roto i te vairaa mau i kua whakaarahia ake ai ki te 450 MHz.

Ko te chipset he matua kotahi. whakamahinga Memory tae 256 MB. Roto pika tukatuka rua shader, kotahi āhuahanga pūtukatuka me shaders akitu. Mahinga tae 98 miriona tapatoru ia te rua, me te 2.5 piriona pika i roto i te wā kotahi.

Adreno 305 kia whakahaere pūmārō rōpinepine mahi ki mata-ki tonu image anti-aliasing, tuwhaina e te scene e toru-ahu i runga i te tāpa, hangaia e rama mahi taputapu ki Arepa Blanding ka riro Z moka ki moka-24. Na neke atu i te 50 waea atamai me papa ki te mahi tatini ki enei whakatere whakairoiro. Te nuinga o nga gadgets i o production.

Reviews

Kua Qualcomm kua mahi hoki i te roa te wa ki GPU Adreno. timata nga putanga tuatahi ki te puta i roto i 2009, ka kua riro kua runga te mākete me te aro kaiwhakamahi. Na i reira e whitu pūtukatuka ki tenei whakatere whakairoiro. I roto i te whānui, e kore ratou e rerekē i ia atu. I te tahi taime iarere wiri kite.

E tonu te iwi nei i waea atamai ki Adreno 305. Reviews te pūtukatuka ataata i roto i ngā rahinga iti. Kei te meinga te reira e te meka e ko te reira he wāhi o te pūrere pūkoro, na riro te reira i te arotake atamai, nui atu i ona wae takitahi.

Kei te mohiotia te reira e te tauira 2013, i riro i te chipset pā ki te wāhanga utu toharite, a whakakitea mahi pūmau, e kore nei e i tu i roto i ki te tahi mea taa ê. pai pūtukatuka ki tenei matua mahi, whakawhetai ki te kaha o ngā tikanga kikokore tiaki te mana motuhake o te pūrere mo te wa roa.

whakaaro te rerekētanga matua o te hoko i te pūrere taua e e taea te kaiwhakamahi e whakarongo ki te Snapdragon 400 kitea i runga i nga ngā Ipurangi, tirohia te katoa, me te tiki i te reira. Otiia i roto i te meka tahuri reira i roto i taua he ahua ngoikore i roto i ētahi wā tahuri atu ki te kore whakamātau te chipset. i meinga e te meka e te Snapdragon poto 400 taea maha tikanga i te torutoru whakarerekētanga, e, ahakoa ko reira Adreno 305, i taea e te tahi atu tohu rerekē tino ēnei raruraru.

Tairanga, he pai nga whakairoiro. e kore ia i unuhia tākaro rerehua, engari i runga i ngā tautuhinga iti akakoromaki i tata kaupapa katoa o te "Play Store". Ko te drawback matua o whakairoiro me pūtukatuka i Qualcomm whakaaro pukā tenei ra. Na inaianei, he maha kaiwhakanao pūrere pūkoro kore hua o tenei kamupene, ka hoatu hiahia ki Mali.
