Qualcomm Adreno 305: zizindikiro ntchito, ndemanga

Kodi ndi Qualcomm Adreno 305, ochepa mukudziwa. Ndipo ngakhale anthu amene ena yankho chinthu izi, si nthawi zonse kumvetsa chimene icho chinali chifukwa. Kuyambira nthawi mu moyo wathu anayamba mafoni anzeru, anali mwamsanga kupeza njira kupangika yafupika. Choncho panali mapurosesa m'manja ndi yaing'ono zithunzi accelerators.

Ndi chiyani icho?

Choncho, zithunzi purosesa, omwe si PC, komanso "anakhala" mu zipangizo athu mafoni, uzigwirizana ndi mavuto masiku ano. ndi amene ambiri:

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

Ichi ndi makampani otchuka kwambiri kuti kale kutsimikiziridwa bata ndi ntchito kudutsa mafoni ndi miyala. Musanawerenge ndi Adreno 305, m'pofunika kumvetsa zimene magawo yodziwika ndi mapurosesa zimenezi.

magawo

Kotero, kumvetsa zimene timakumana zithunzi accelerator, ndi kunena chinachake chokhudza ntchito yake, muyenera kuyang'ana zinthu zitatu:

• Chiwerengero cha Triangles pa mphindi.
• Chiwerengero cha pixels pa mphindi.
• Chiwerengero cha ntchito akuyandama mfundo.

N'zoona kuti mudziwe onse akhoza kusanthula yekha ndi akatswiri. Wosuta pafupifupi adzanena kuti ziwerengero pang'ono pa magawo awa. Choncho tiyeni tifike pomwe mwachindunji chitsanzo chathu mafoni Adreno 305.

Qualcomm

Kampaniyi zachitika purosesa kuposa wina pafoni. Mwachitsanzo, mafoni ambiri akhoza kudzitama za kukhala mmodzi wa Snapdragon banja zitsanzo. Mfundo lakonzedwa mafoni ndi miyala, chikugwira ndi dzanja zomangamanga, ndi zigawo kulankhulana. Ndi kachitidwe mafoni pa Chip sitolo chipset, kwa amene amanena za ngwazi za taphunzira.

Nthawi zambiri, anthu Snapdragon kwake awiri zino, yoyamba analandira zolozera S1 / S2 / S3 / S4, ndipo chachiwiri - 2xx / 4xx / 6xx / 8xx. Zinali mndandanda chachiwiri ndi Adreno 305. Ndi "zobisika" m'banja Snapdragon 400 ndipo waperekedwa kwa anthu ambirimbiri zosintha.

Snapdragon 400

Nthawi zambiri, anthu amene kumvetsa chitsanzo cha purosesa, chipset, pachimake, nsanja ndi zinthu zina, nthawi yomweyo zindikirani njomba zauve. Banja limeneli ukufanizidwa osati ndi chitsanzo chimodzi. Pali Mabaibulo angapo ndi mapangidwe osiyana, mitima ndi mafurikwense. Koma ndinganene, aliyense wa iwo ndi likutipatsa 305-TH phata. Ndi zonse, choncho, kuwonetsera kusamvana yofanana - 1280x800.

zachilendo

Chitsanzo choyamba ndi "adrenergic" 305 nambala 8225. The chipset anapangidwa pa 28 nm ndondomeko luso ndi luso mphamvu otsika. Purosesa anakhala kotekisi-A7 pa mitima anayi ndi pafupipafupi 1200MHz. Zithunzi accelerator amathandiza osiyanasiyana kugwirizana opanda zingwe: m'mphepete, Bluetooth, Wi-Fi, GSM, HSPA + ndi GPRS. Izi njira idatha mu zitsanzo zambiri chipangizo, Pakati - ndi Samsung Way ndi S5, ndi S3 ndi Tab 4, Sony Xperia m2, ndi Microsoft a Lumia 640 XL.

The kusinthidwa zotsatirazi pafupifupi anabweretsa palibe kusintha makhalidwe kusintha yekha Adreno 305. CPU pafupipafupi kuchokera 1.2 GHz kwa 1.4 GHz, ndi accelerator anapita ku Samsung Way S3 SS.

kusintha

Baibulo wachitatu wa chipset ankadziwidwira kotala chachinayi cha 2013. Zinali ndiye kuti anayamba kuŵeta. zipangizo anawonjezera kuti mndandanda ndi anayi Nokia Lumia zitsanzo chipset nawonso anayamba kugwiritsidwa ntchito zitsanzo za mafoni Huawei, HTC ndi Acer. Mbali luso ndi mavuto pang'ono. Anabwerera pafupipafupi 1.2 GHz, ndi mndandanda kusinthidwa Intaneti opanda zingwe akuthandiza: DC-HSPA + ndipo LTE. A luso kukumbukira ndi kukonzedwa pa LPDDR2 LPDDR3.

Nsanja latsopano

The kusinthidwa zotsatirazi chipset ndi zachititsa kuti kusintha ofunika. Choncho, Quad kotekisi-A7 m'malo mwa Krait wapawiri 200 amene ali pafupipafupi 1.2-1.4 GHz. Pali deta pa buku choyamba mlingo posungira 32 KB, wachiwiri - 1 MB. Sinthani luso kukumbukira. Mu otsiriza Mabaibulo anayi purosesa kusintha kwa Krait 300 ndipo umagwira ntchito pa pafupipafupi 1700 MHz. Pankhaniyi, nthawi iliyonse mndandanda wa zipangizo kuti ntchito ndi chipset ndi, chinawonjezeka ndi zitsanzo 3-5.

poyerekeza

Yerekezerani ndi Adreno 305 Adreno 225 - ambiri. Ichi ndi chifukwa chakuti akulu Baibulo ndi kupitiriza kwa wamng'ono. Ndipotu 305-TH chitsanzo - izi pomwe 225th. Iye poyamba anaonekera mu Snapdragon S4 ovomereza, koma bwino kwambiri zimatheka m'banja Snapdragon 400. The kusiyana zachilendo lagona modernity ake. Iwo amathandiza ndi ambiri umisiri watsopano, n'zosavuta kuthana ndi API ndi, Direct3D 9,3, OpenGL ES 3,0 ndi CL 1.2.

kuyezetsa

Magwiridwe Adreno 305 akhoza kulitsimikizira mayesero. Kumene, zimadalira zimene nsanja anaika chipset ndi purosesa momwe ntchito pamodzi. Kore wotchi pafupipafupi ukufika 450 MHz. phidigu chizindikiro ndi mwa 0,02 ndi limasonyeza GPU processing mphamvu ya purosesa lapansi.

0,8 GPixel / s - ndi liwiro pixels lapansi. chizindikiro Kudziwa chiwerengero cha pixels kuti amalembedwa pa mphindi. Monga tanena kale, chitsanzo amathandiza 9,3 buku la DirectX, amene kwambiri bwino zithunzi mu masewera. Version wa OpenCL 1.1 - ndi luso kuti amalola ena mapulogalamu ntchito zithunzi accelerator zolinga sanali mawonekedwe.

TechProcess ngale - 28 nm. Poyerekeza ndi Baibulo chisanadze ano ndi chithunzi chachikulu, koma ndi 2013 kunali ndale basi chipset miyeso.

Features

Adreno 305 - izi ndi zabwino kanema purosesa, amene anakhala wotchuka mu 2013. Zinali ndiye kuti mafoni zipangizo akhala mofulumira okonzeka ndi chitsanzo ichi. Iye analandira wogwirizana shader zomangamanga. Pafupifupi kanema pafupipafupi ukufika 266 MHz Komatu ankadziwika kale akudzutsa 450 MHz.

The chipset ali pakati umodzi. Memory ntchito ukufika 256 MB. Mkati awiri shader pixels processing, wina Masamu purosesa ndi vertex shaders. Magwiridwe ukufika Triangles miliyoni 98 pa mphindi ndi pixels biliyoni 2.5 mu nthawi yomweyo.

Adreno 305 angafunikire kuchititsa tessellation hardware ukugwira ndi Wodzaza odana aliasing image, ukugawa atatu azithunzi omwe tikunena zinachitika pa matailosi, ndi kuyatsa amalenga hardware ntchito ndi Alpha Blanding ndipo analandira Z gawo lotetezedwa ndi 24-bit. Tsopano oposa 50 mafoni anzeru ndi mapiritsi dazeni ntchito ndi zithunzi izi accelerator. Kwambiri ndi zipangizo kunja kupanga.

Reviews

Qualcomm wakhala akugwira ntchito kwa nthawi yaitali ndi GPU Adreno. Sewero loyamba anayamba kuoneka mu 2009 ndipo anali atayamba kale pa msika ndi owerenga tcheru. Tsopano pali mapurosesa asanu ndi izi accelerator zithunzi. Ambiri, iwo alibe amasiyana Chrixitu. Nthawi zina noticeable kugwedera mafurikwense.

Pali anthu amene ali ndi mafoni anzeru ndi Adreno 305. Reviews ndi purosesa kanema zedi yaing'ono. Iwo amayamba ndi chakuti ndi mbali yofunika ya foni, kotero izo zikuchoka ndemanga yamakono osati zigawo zake payekha.

Amadziwika kuti chitsanzo 2013, amene analandira chipset amatanthauza pafupifupi gawo mtengo, ndipo anasonyeza ntchito khola, sanali onekera ndi chinachake chapadera. Mapurosesa ndi pakati ichi ntchito bwino, chifukwa cha mphamvu ya njira Taphunzira kusunga kudziyimira pawokha chipangizo kwa nthawi yaitali.

The sangathe waukulu kugula chipangizo otere ankaona kuti wosuta akhoza kulabadira Snapdragon 400 anapezeka pa specifications Internet, tione onse adzautenge. Koma zoona kunapezeka kuti chipset penapake ofooka zina zinapezeka mayeso kulephera. Mavuto awa ankayambitsa ndi choona kuti achidule Snapdragon 400 akhoza zambiri zikutanthauza zosintha ochepa, zomwe, ngakhale kuti unali Adreno 305, zizindikiro ena osiyana kwambiri.

Cacikulu, ndi zithunzi anali wabwino. Iye anali anakoka zidole zokwera mtengo, koma pa zoikamo otsika kupirira pafupifupi ntchito zonse za "Play Store". The drawback chachikulu cha zithunzi ndi mapurosesa kwa Qualcomm ankaona kutenthedwa lero. Kotero tsopano, ambiri mafoni opanga chipangizo amakana mankhwala a kampani ndi kupereka mmalo Mali.
