Huawei nhasi akafumura zviri pamutemo mureza wayo mutsva-chip chikuva Kirin 2019 990G paIFA 5. Chinhu chakakosha chechigadzirwa chitsva ndeye yakavakirwa-mukati 5G modem, sezvinoratidzwa muzita, asi nekuwedzera Huawei anovimbisa kushanda kwepamusoro uye kugona kwepamusoro kune chekuita nehungwaru hwekugadzira.
Iyo Kirin 990 5G single-chip chikuva inogadzirwa pachishandiswa yakavandudzwa 7-nm process tekinoroji uchishandisa EUV lithography (7-nm+ EUV). Panguva imwecheteyo, chigadzirwa chitsva ndechimwe chezvakanyanya kuoma processors emafoni, ane 10,3 bhiriyoni transistors.
Chekutanga pane zvese, Huawei anotarisa pachokwadi chekuti Kirin 990 5G ndiyo yekutanga pasi rose-chip smartphone chikuva chine yakavakirwa-mukati 5G modem. Mune ikozvino 5G smartphones, vagadziri vanoshandisa SoC ine yakavakirwa-mukati 4G modem uye yakaparadzana 5G modem. Zvechokwadi, bundle rakadaro rinopedza simba rakawanda (kusvika ku20%) pane imwe crystal, uye ine 36% yakakura nzvimbo.
Iyo modem muKirin 990 5G inokwanisa kugamuchira uye kutumira data nekumhanya kunosvika 2,3 uye 1,25 Gbps, zvichiteerana. 5G NSA uye SA modes inotsigirwa. Pamusoro pe5G network, kutsigirwa kwezvizvarwa zvakapfuura zvekutaurirana kweserura kwakachengetedzwa zvakare.
Iyo itsva neuroprocessor module NPU ine basa remabasa ehungwaru hwekugadzira. Inosanganisira maviri "mahombe" uye "diki" mabhuroko. Iwo ekutanga anogadzirwa paDa Vinci architecture uye akagadzirirwa kuita "anorema" mabasa. Iyo "diki" core, zvakare, inonyanya kushandisa simba. Kazhinji, Kirin 990 iri pamberi pevakwikwidzi vayo maererano neAI, yakadai seApple A12 uye Qualcomm Snapdragon 855, uye panguva imwechete inoshandisa simba shoma.
Kirin 990 ine masere processor cores, akakamurwa kuita masumbu matatu. Iro "hombe" cluster rinosanganisira maviri Cortex-A76 cores ane frequency ye2,86 GHz, iyo "yepakati" zvakare ine maviri Cortex-A76 cores, asi ine frequency ye2,36 GHz, uye "diki" cluster ine ina Cortex-A55 cores. ine frequency ye1,95 .980 GHz. Chaizvoizvo, zvichienzaniswa neKirin 990, chimiro hachina kuchinja, asi mafambiro akawedzera. Sekureva kwaHuawei, iyo Kirin 5 855G processor iri pamberi peSnapdragon 10 ne9% mumabasa ane tambo imwe chete uye 12% mumabasa ane tambo dzakawanda. Panguva imwecheteyo, chigadzirwa chitsva cheChinese chinoshanduka kuita 35-855% simba rakawanda kupfuura Snapdragon XNUMX.
Asi iyo graphics processor yakaitika zvakanyanya kukosha shanduko. Kana iyo Kirin 980 yakashandisa gumi-musimboti Mali-G10, saka iyo itsva Kirin 76 yatove negumi nematanhatu vhezheni yeMali-G990. Somugumisiro, maererano nekushanda kwemifananidzo, Kirin 16 iri 76% mberi kweSnapdragon 990, uye panguva imwechete inoshandisa 855% simba shoma.
Isu tinoona zvakare kuti Huawei akashongedza iyo processor nyowani ne "smart" cache, iyo inopa kuwedzera kwekuita kwe15%. Uye Kirin 990 yakagamuchirawo itsva Dual ISP image processing processor, inoshanda 15% nekukurumidza uye zvakanyanya, uye inoderedzawo ruzha mumapikicha nemavhidhiyo ne30 uye 20%, zvichiteerana.
Sezvineiwo, Huawei achaburitsawo Kirin 990 processor isina yakavakirwa-mukati 5G modem. Iyi chip icharatidzawo yakaderera frequency ye "pakati" uye "madiki" masumbu - 2,09 uye 1,86 GHz, zvichiteerana, uye NPU yayo ichave ne "hombe" imwe chete "diki" musimboti.
Yekutanga smartphone yakavakirwa paKirin 990 ichave mureza Huawei Mate 30, iyo icharatidzwa munaGunyana 19 pachiitiko chakakosha muMunich.
