I-Ampere idedela iprosesa engu-80-core ye-ARM: ishesha ize iye enkambweni eyi-128 ekugcineni kweye

Ukwakhiwa kwe-ARM manje sekuthandwa kakhulu. Akukhona ukuthi igqame ngokuphelele endle yamaselula, kodwa futhi kuyathuthuka esikhungweni sedatha, izinsizakalo zamafu, nezinkundla zekhompiyutha ezisebenza kakhulu. Abakhiqizi abaningi bakhiphe amaprosesa we-multM core, frequency ephezulu. I-upstart nayo iyisakhiwo sokwakha i-ARM, futhi ngisho ne-Apple isebenzisa ubuciko bokwakhiwa kwe-ARM ukukhulisa ama-chip ayo.

Namuhla, i-Ampere Computing (i-Ampere Computing) idedele isizukulwane sayo sokuqala se-Altra processors uchungechunge, ikakhulukazi kubahlinzeki bezinsizakalo ezinkulu zamafu, abaziwa ngokuthi ngumndeni wokuqala wama-80-basic native processor wefu, bazophuthuma kuma-cores angama-128 uma kuphela unyaka.

Iprosesa ye-Ampere Altra isuselwe ekwakhiweni kwebhizinisi le-ArM Neoverse N1, okwadutshulwa kane okwenziwe nge-super-scalar, futhi isekela isethi yemiyalo ye-ARM v8.2, futhi yadonsa kwezinye izici ze-ARM v8.3 kanye v8.5, enezingxenye ezimbili ze-SIMD 128 bits, isekela indawo ye-FP16 ezintantayo, i-INT integer arithmetic, i-TSMC 7nm inqubo yokwenza inqubo.

Wonke ama-cores axhunyiwe ochungechungeni ngenethiwekhi yegridi ye-Mesh. Umgogodla ngamunye unenqolobane yokufundisa esezingeni lokuqala engu-64KB, inqolobane yedatha yokuqala engu-64KB, kanye ne-1MB yesigaba sokugcina. Wonke ama-cores abelana nge-32MB yenqanaba lesithathu, nawo wonke amazinga e-cache asekela i-ECC.

Imemori isekela iziteshi eziyisishiyagalombili ze-DDR4-3200 ECC, ifinyelela kwababili esiteshini ngasinye, iziteshi ezingafika ku-16, namandla aphezulu we-4TB.

Ixhasa isiteshi esisodwa noma esilinganayo esisebenza ngokufana, ngalinye lihlinzeka ngamabhasi ayi-128 PCIe 4.0, angama-32 kuwo asetshenziselwa ukuxhumana kanye nama-96 angaphandle, isiteshi esithandanayo singanikeza i-192 PCIe 4.0.

Uchungechunge lwe-Altra lunikela ngamamodeli afinyelela ku-11, igama lemodeli lingabizwa ngokuthi imodeli yezimboni, igama lekhodi kanye nenombolo eyisiqalo kanye nemvamisa, elula futhi icacile, isibonelo, i-Flagship "Q80-33" ingumgogodla wama-80 (umucu wama-80), u-3.3 I-GHz, umsebenzi wokuqamba wokushisayo Ukusetshenziswa kwe-250W-Q ifana negama lekhodi "i-QuickSilver" (umlingiswa osheshayo wesilivere).

Amanye amanye ama-cores amathathu yi-3.0GHz / 210W, 2.6GHz / 175W, i-2.3GHz / 150W, kukhona futhi umgogodla angama-72, ama-cores amane angama-64, umgogodla ongu-48, umgogodla ongu-32, kanti ukusetshenziswa kwamandla kwamandla okuklama okushisayo okungenani yi-45W - -Ukusetshenziswa kwamandla okushisisa komoya okusetshenziselwa ama-cores angama-32 agcwele inkumbulo ye-4TB kuzonyukela ku-58W.

Okulandelayo, i-Ampere izokwethula uhlelo oluthuthukisiwe lochungechunge lwe-Altra Max, oluqoshwe ngekhodi "Mystique" (Umfazi womlingo omangalisayo), ukwakhiwa okusha kwe-chip kuseyinethiwekhi yegridi, inani eliphakeme lamakholi lifinyelela ku-128, inkumbulo, i-PCIe nokunye imininingwane ayiguquki, isampula kwikota yesine, ukukhiqizwa kwesisindo ngonyaka olandelayo.

Uma sibheka phambili, i-Ampere futhi idizayina nenkosikazi entsha yesizukulwane sesibili "Siryn" (Marvel uhlaka Sonic), inqubo yokukhiqiza ivuselelwa ngo-5nm, inani lamakholi selinqunyelwe (alishicilelwe), kulindeleke ukuthi lixhase i-DDR5, PCIe 5.0 , kanti i-chip test isithwetshiwe Kulindelwe ukuthi izofakwa isampula ngasekupheleni konyaka olandelayo.
