Khampani ea California e hlahisitse processor ea pele ea indasteri ea 80-core ARM e ipapisitseng le meralo ea 64-bit .
Ka lilemo tse 'maloa, litsebi li ntse li bolela esale pele hore sethala sa ARM se tla qothisana lehlokoa le x86 litsing tsa data, empa sena ha se etsahale. Qetellong ea 2019 moo , AMD e na le 4,5%.
Leha ho le joalo, processor e ncha ea ARM e bencheng e felletseng ea SPECrate 2017 e bonts'a ts'ebetso e betere ho feta 64-core AMD EPYC e potlakileng haholo kapa Xeon ea mantlha ea 28 ea lelapa la Cascade Lake. Ena e se e ntse e le tseko e tebileng (le hoja liphetho tsa benchmark li batla li "sothehile", bona ka tlase).
Monyetla o ka sehloohong oa ARM ke matla a matla, ao, ka tlhaloso, a ke keng a bapisoa le li-processor tsa x86 ka lebaka la meralo. 80-core Ampere Altra e na le TDP ea 45-210W le lebelo la oache la 3GHz.
Ampere e lumela hore khoele e le 'ngoe ea mantlha ho e-na le tse peli e kenya letsoho ts'ireletsong e phahameng, kaha moralo ona o sireletsa li-cores tsa motho ka mong ho tsoa litlhaselong tse lehlakoreng tse kang Meltdown le Specter.
Processor e etselitsoe lits'ebetso tsa seva tse kang analytics ea data, bohlale ba maiketsetso, database, polokelo, mehala ea mehala ea mohala, komporo ea moeli, ho amohela webosaete, le lits'ebetso tsa maru. Haholo-holo bakeng sa lisebelisoa tsa ho ithuta mochine, hardware e tšehetsa liforomo tsa data tsa FP16 (half-precision) le INT8 (single-byte integer). Ho boetse ho na le hardware e potlakileng ea AES le SHA-256 hashing.
Li-chips li entsoe ka mokhoa oa TSMC oa 7nm. Mehlala ea pele ea CPU e se e rometsoe ho bao e ka bang bareki, 'me tlhahiso ea bongata e reretsoe ho qala bohareng ba 2020.
CEO ea Ampere le mopresidente oa mehleng oa Intel Renée James ba thehile Ampere Computing ka Mphalane 2017 ho tsoa ho Applied Micro Circuits Corporation e senyehileng (1979-2017), eo hape e entseng li-processor tsa seva tsa ARM. Haholo-holo, ka 2011 e hlahisitse sethala sa 64-bit X-Gene se thehiloeng ho ARMv8-A.
Hona joale James o kopanya maemo a hae e le CEO le Molula-setulo oa Boto ea Batsamaisi ea Ampere Computing le boemo ba Motlatsi oa Molula-setulo oa Komiti ea Naha ea Boeletsi ea Ts'ireletso ea Mehala, e eletsang Mopresidente oa United States.
Kea ipotsa hore na teko e ncha ea ho tlisa li-processor tsa ARM 'marakeng oa seva e tla atleha hakae.
"Re lokolotse processor e nang le li-cores tse ngata ka ho fetisisa 'marakeng," James. “Joale re e rometse [bakeng sa liteko] ho tse ling tsa litsi tse kholo ka ho fetisisa indastering… Ke nahana hore batho ba tla makala. [Ho nka sebaka sa mahlale a fetileng] kamehla ho na le ntho e ncha. 'Me haeba e sa tsoe k'hamphaning e teng, joale e tsoa ho e ncha. Ho thabisa haholo ho sebetsa ho seo ke se bonang e le mohato o latelang indastering. "
Ho bile le lipuo tse ngata ka li-chips tsa 64-bit ARM lilemong tse fetileng, ha AMD le Applied Micro e boletsoeng ka holimo e ne e leka ho hlahisa li-processor tse tšoanang. Empa lik'hamphani tsena li ile tsa hlōleha. AMD e ile ea koala morero oa eona oa ARM, ha thepa ea Applied Micro Khamphani ea Macom. Ka 2017, Sehlopha sa Carlyle se ile sa reka karolo ea processor ea ARM ho eona. Tumellano e ile ea koaloa bofelong ba selemo sa 2019, mme James o ile a nka sebaka sa ho ba CEO oa k'hamphani e ncha, a siea boemo ba hae e le COO ho Carlyle Group.

Wittich o boetse a fana ka papiso le processor ea 28-core Xeon ea lelapa la Cascade Lake. Motlakase oa Ampere Altra o ile oa e feta "ka makhetlo a 2,23 ts'ebetsong le makhetlo a 2,11 ts'ebetsong ea matla". Mona, lipalo li ne li bapisoa le 28-core Xeon Platinum 8280 (205 W), 'me katleho ea matla e ne e baloa ho latela motheo o le mong.
Ho palo e felletseng ea SPECrate 2017, processor ea Ampere Altra ho tlalehoa e na le lintlha tse fetang 259. sena se tlase ho ts'ebetso e phahameng ea ASUS RS720A-E9(KNPP-D32) Server System (2.20 GHz, AMD EPYC 7601) le ASUS RS500A-E10(KRPA-U16) Server System 2.25 GHz, AMD EPYC 7742.
Leha ho le joalo, papisong ea ts'ebetso, Ampere e sebelisitse karolo ea 0,85 ho liphetho tsa AMD ka lebaka la ts'ebeliso ea sephutheloana sa pokello ea AMD64 ho bokella khoutu ea benchmark ha e bapisoa le GCC 8.2, eo e e sebelisitseng ka boeona, kaha moqapi oa AMD C/C++ o hlahisa ho feta. khoutu e ntlafalitsoeng ho feta GCC bakeng sa ARM.

Bongata ba liteko tsena ha boa ka ba atleha. Empa ho na le matšoao a hore boemo boa fetoha. Ka December 2019 Amazon li-server tse nang le li-processor tsa 64-core ARM ke system-on-a-chip mokokotlong o tšoanang le oa mantlha oa ARM Neoverse N1. Litekong tse ling, maemo a ARM (M6g le M6gd) a sebelitse hantle, 'me ka linako tse ling hantle ho feta x86.
Ka Pulungoana 2019, ho ile ha tlalehoa hore Nuvia ea Amerika e qalile .
