48 cores

Qetellong ea 2018, Intel tsebisitsoe Mehaho ea Cascade-AP. Li-processor tsena li tla tšehetsa li-cores tse 48, li be le sebopeho sa li-chip tse ngata le likanale tse 12 tsa DDR4 DRAM. Mokhoa ona o tla fana ka boemo bo phahameng ba ho bapisa, bo thusang ho sebetsana le data e kholo marung. Ho lokolloa ha lihlahisoa tse thehiloeng ho Cascade-AP ho reriloe ka 2019.

sebetsa ho li-processor tsa 48-core le ho IBM le Samsung. Ba theha li-chips tse ipapisitseng le meaho MATLA 10. Lisebelisoa tse ncha li tla tšehetsa protocol ea OpenCAPI 4.0 le bese ea NVLink 3.0. Ea pele e tla fana ka tumellano ea morao le POWER9, 'me ea bobeli e tla potlakisa phetiso ea data lipakeng tsa likarolo tsa sistimi ea khomphutha ho fihlela ho 20 Gbit/s. Ho boetse hoa tsebahala hore POWER10 e na le mahlale a macha a I/O le li-control tse ntlafalitsoeng tsa memori.

Qalong, lichifi li ne li lokela ho etsoa GlobalFoundries ho sebelisoa theknoloji ea 10nm, empa joale khetho e ile ea etsoa molemong oa theknoloji ea TSMC le 7nm. Nts'etsopele e reretsoe ho phetheloa lipakeng tsa 2020 le 2022. Ka 2023, mokhatlo o tla lokolla lichifi tsa POWER11, tse entsoeng ka theknoloji ea 7nm e nang le transistor density ea 20 billion.

Ka data ea benchmark, 48-core Intel solutions e sebetsa ka potlako ka makhetlo a mararo ho feta balekane ba bona ba AMD (ka li-cores tse 32). Ha e le POWER10, ha ho letho le tsejoang ka ts'ebetso ea eona hajoale. Empa lebelletsoe hohore moloko o mocha oa li-processor o tla fumana ts'ebeliso lefapheng la analytics le tlhahlobo e kholo ea data.

56 cores

Li-chips tse tšoanang li sa tsoa phatlalatsoa ke Intel - li tla etsoa ho sebelisoa theknoloji ea ts'ebetso ea 14-nm. Ba ts'ehetsa li-module tsa memori tsa Optane DC tse ipapisitseng le 3D Xpoint mme ba na le likhechana tsa bofokoli ba Specter le Foreshadow. Lisebelisoa tse ncha li tla le liteishene tsa memori tsa 12 le li-accelerator tse ngata tse hahiloeng bakeng sa ho rarolla mathata marung, hammoho le ho sebetsa le litsamaiso tsa AI le ML le marang-rang a 5G.

Moetso oa li-flagship o nang le li-cores tsa 56 o tla bitsoa Platinum 9282. Lebelo la oache e tla ba 2,6 GHz, le bokhoni ba ho feta ho 3,8 GHz. Chip e na le 77MB ea cache ea L3, litselana tse mashome a mane tsa PCIe 3.0, le 400W ea matla ka soketeng. Theko ea li-processor e qala ho tloha ho lidolara tse likete tse leshome.

Bahlahisi ketekahore Optane DC e tla fokotsa nako ea ho tsosolosa lisebelisoa tsa k'homphieutha ho tloha metsotso e 'maloa ho ea metsotsoana e mengata. Hape, chip e ncha e tla u lumella ho sebetsa palo e kholo ea mechini e fumanehang sebakeng sa maru. Motlakase oa 56-core o lebelletsoe ho fokotsa litšenyehelo tsa ho boloka VM e le 'ngoe ka 30%. Leha ho le joalo, litsebi ba re hore li-processor tse ncha ha e le hantle ke mofuta o ntlafalitsoeng oa Xeon Scalable. Microarchitecture le lebelo la oache la chip li lula li tšoana.

64 cores

processor e joalo qetellong ea selemo se fetileng tsebisitsoe ho AMD. Re bua ka li-chips tse ncha tsa 64-core Epyc tse ipapisitseng le theknoloji ea ts'ebetso ea 7nm. Li lokela ho hlahisoa selemong sena. Palo ea liteishene tsa DDR4 e tla ba tse robeli ka sekhahla sa 2,2 GHz, 'me 256 MB ea cache ea L3 le eona e tla eketsoa. Ho tla ba le li-chips tšehetso 128 PCI Express 4.0 ho e-na le mofuta oa 3.0, e tla tla habeli ho feta.

Empa palo ea baahi ba Hacker News e dumelanghore kholo ea tlhahiso ha se kamehla e leng molemo ho basebelisi ba nang le bokhoni. Kamora ho potlakisa matla, theko ea li-processor le eona ea eketseha, e ka fokotsang tlhoko ea bareki.

Prosesa ea 64-core e boetse e ntlafalitsoe ke Huawei. Li-chips tsa bona tsa Kunpeng 920 ke li-processor tsa seva tsa ARM. Tlhahiso e etsoa ke TSMC e sebelisa theknoloji ea 7nm process. Li-server tsa TaiShan li se li kentsoe lisebelisoa tse ncha tse nang le maqhubu a oache a 2,6 GHz, tšehetso bakeng sa li-interface tsa PCIe 4.0 le CCIX. Tse morao li etselitsoe ho sebetsa ka data e kholo le lits'ebetso tse lerung.

Basebelisi ba Huawei ba se ba bontšitse keketseho ea ts'ebetso ea 20% litekong ka li-server tsa TaiShan. Ntle le moo, bandwidth ea memori e eketsehile ka 46% ha e bapisoa le lihlahisoa tse fetileng tsa k'hamphani.

Kakaretso

Ka kakaretso, re ka re tlholisano 'marakeng oa chip ea seva ka 2019 e tla ba holimo. Baetsi ba ntse ba eketsa li-cores tse ngata, ba hlomella li-processor ka tšehetso bakeng sa liprothokholo tse ncha tsa phetisetso ea data, le ho leka ho etsa hore lihlahisoa li sebetse ka bongata. Ka lebaka la sena, beng ba litsi tsa data ba na le menyetla e mengata ea ho khetha litharollo tse loketseng mefuta e itseng ea meroalo le mesebetsi e itseng.
