California tuam txhab qhia txog kev lag luam thawj 80-core ARM server processor raws li 64-ntsis architecture .
Tau ntau xyoo tam sim no, cov kws tshaj lij tau kwv yees tias ARM platform yuav sib tw nrog x86 hauv cov chaw khaws ntaub ntawv, tab sis qhov no tsis tshwm sim. Thaum kawg ntawm 2019 muaj , AMD muaj 4,5%.
Txawm li cas los xij, tus tshiab ARM processor hauv SPECrate 2017 integer benchmark qhia tau hais tias kev ua tau zoo dua li qhov ceev tshaj plaws 64-core AMD EPYC lossis 28-core Xeon ntawm Cascade Lake tsev neeg. Qhov no twb yog ib qho kev thov loj (txawm tias cov txiaj ntsig ntawm qhov ntsuas tau me ntsis "twisted", saib hauv qab).
Qhov txiaj ntsig tseem ceeb ntawm ARM yog kev siv hluav taws xob, uas, los ntawm kev txhais, tsis tuaj yeem sib tw los ntawm x86 processors vim yog architecture. 80-core Ampere Altra muaj TDP ntawm 45-210 W thiab moos ceev ntawm 3 GHz.
Ampere ntseeg hais tias ib tug xov ntawm ib tug core es tsis txhob ntawm ob ua rau kom muaj kev ruaj ntseg ntau dua vim hais tias qhov tsim no zoo dua tiv thaiv ib tug cores los ntawm sab-channel tawm tsam xws li Meltdown thiab Spectre.
Lub processor yog tsim los rau cov neeg siv cov ntawv thov xws li cov ntaub ntawv analytics, kev txawj ntse, databases, cia, telecom stacks, ntug xam, web hosting thiab huab siv. Tshwj xeeb tshaj yog rau cov ntawv thov kev kawm tshuab, kev txhawb nqa kho vajtse rau FP16 (ib nrab tus lej) thiab INT8 (ib leeg-byte integer sawv cev) cov ntaub ntawv tau raug siv. Kuj tseem muaj kho vajtse acceleration rau AES thiab SHA-256 hashing.
Cov chips yog tsim los ntawm TSMC cog siv 7 nm txheej txheem thev naus laus zis. Thawj cov qauv CPU tau raug xa mus rau cov neeg siv khoom muaj peev xwm, thiab kev tsim khoom loj tau npaj pib thaum nruab nrab xyoo 2020.
Ampere CEO thiab yav dhau los Intel Thawj Tswj Hwm RenΓ©e James tau tsim Ampere Computing thaum Lub Kaum Hli 2017 ntawm lub hauv paus ntawm kev lag luam siv Micro Circuits Corporation (1979-2017), uas kuj tsim ARM server processors. Tshwj xeeb, hauv 2011 nws tau qhia txog 64-ntsis X-Gene platform raws li ARMv8-A.
James tam sim no sib txuas cov haujlwm ntawm CEO thiab Thawj Tswj Hwm ntawm Pawg Thawj Coj ntawm Ampere Computing nrog txoj haujlwm ntawm Tus Lwm Thawj Coj ntawm Pawg Neeg Saib Xyuas Kev Ruaj Ntseg Hauv Lub Tebchaws, uas qhia rau Thawj Tswj Hwm ntawm Tebchaws Meskas.
Kuv xav paub seb qhov kev sim tshiab los coj ARM processors rau lub lag luam server yuav ua li cas.
"Peb tso tawm cov processor nrog ntau tshaj plaws ntawm cov cores ntawm kev ua lag luam," James. "Tam sim no peb tau xa nws [rau kev sim] rau qee qhov chaw muab huab cua loj tshaj plaws hauv kev lag luam ... Kuv xav tias tib neeg yuav xav tsis thoob. [Cov thev naus laus zis dhau los] yeej ib txwm hloov los ntawm ib yam tshiab. Thiab yog hais tias tsis yog los ntawm ib lub tuam txhab uas twb muaj lawm, ces los ntawm ib tug tshiab. Nws zoo siab heev los ua haujlwm ntawm qhov kuv pom raws li theem tom ntej ntawm kev lag luam. "
Muaj ntau cov lus hais txog 64-ntsis ARM server chips nyob rau xyoo dhau los, thaum AMD thiab cov lus hais txog Applied Micro sim tsim cov txheej txheem zoo sib xws. Tab sis cov tuam txhab no ua tsis tiav. AMD kaw nws txoj haujlwm ARM, thiab Applied Micro cov cuab tam Macom tuam txhab. Hauv 2017, Carlyle Group yuav nws ARM processor faib. Qhov kev pom zoo raug kaw thaum kawg ntawm 2019, thiab James tau los ua CEO ntawm lub tuam txhab tshiab, tawm hauv nws txoj haujlwm ua COO ntawm Carlyle Group.
Ob Ampere server platforms: Mt. Jade thiab Mt. Daus
Ampere Altra's single-threaded cores thiab "ntxhiab, lub zog-npaum servers" uas tuaj yeem tsim los ntawm cov CPUs no yuav tso cai rau cov neeg siv khoom "ua kom muaj ntau qhov kev pabcuam uas lawv tuaj yeem xa mus rau hauv huab," lub tuam txhab tau hais.
Ampere Altra processor yog raws li lub platform . Cov lus pom zoo ntawm cov servers tshiab tau txais los ntawm engineers ntawm Microsoft Azure, Oracle, Canonical, VMware, Kinvolk, Packet, Lenovo, Gigabyte, Wiwynn thiab Micron, txhua tus tau hais hauv xov xwm tshaj tawm.
Server Mt. Jade rau ob processors (160 cores): cov ntaub ntawv tshuaj xyuas, database, web
Lub tuam txhab hais tias cov software tau npaj ua haujlwm nrog Ampere Altra: "Qhov loj tshaj plaws tam sim no yog tias yog tias koj saib txhua txheej, OS txheej, txhua yam ntawm Linux mus rau BSD rau Windows txhua tus txhawb nqa ARM," said Jeff Wittich Wittich, Senior Vice President ntawm cov khoom ntawm Ampere. - Rau virtualization, peb muaj kev txhawb nqa rau Kubernetes, Docker, VMware thiab KBM. Txhua yam tau txais kev txhawb nqa nyob ntawd. Ntawm daim ntawv thov, txhua yam uas ua haujlwm hauv huab hnub no twb ua haujlwm ntawm no. "
Server Mt. Daus ntawm ib lub processor: ntug kev suav, kev pabcuam kev sib txuas lus, lub vev xaib, khaws cov ntaub ntawv

Benchmarks
Jeff Wittich hais tias Ampere processor ua tau 4% zoo dua li AMD tus ceev tshaj EPYC processor hauv cov qauv ntsuas thiab siv 14% tsawg zog. Peb tab tom tham txog 64-core EPYC processor
7742 nrog TDP ntawm 225 W thiab tus nqi ntawm $ 6950. Qhov no yog qhov muaj zog tshaj plaws hauv EPYC 2 processor tsev neeg raws li Zen 2 microarchitecture. Tsev neeg tau tshaj tawm thaum Lub Yim Hli 2019.
Wittich kuj tau sib piv nrog 28-core Xeon processor ntawm Cascade Lake tsev neeg. Lub Ampere Altra processor ua tau zoo tshaj nws los ntawm "2,23 zaug hauv kev ua tau zoo thiab 2,11 zaug hauv kev siv hluav taws xob." Ntawm no qhov kev ua tau zoo tau muab piv nrog 28-core Xeon Platinum 8280 (205 W), thiab kev siv hluav taws xob tau suav nrog ib tus tub ntxhais.
Lub Ampere Altra processor tau tshaj tawm cov qhab nia siab dua 2017 hauv SPECrate 259 tus lej ntsuas. qhov no yog qhov qis dua rau qhov ua tau zoo ntawm ASUS RS720A-E9 (KNPP-D32) Server System (2.20 GHz, AMD EPYC 7601) thiab ASUS RS500A-E10 (KRPA-U16) Server System 2.25 GHz, AMD EPYC 7742.
Txawm li cas los xij, hauv kev sib piv kev ua tau zoo, Ampere tau siv qhov tseem ceeb ntawm 0,85 rau AMD cov txiaj ntsig vim yog kev siv AMD64 compiler suite los sau cov lej cim, piv rau GCC 8.2 nws siv nws tus kheej, txij li AMD C / C ++ compiler ua kom zoo dua. code tshaj GCC ntawm ARM.
Txawm hais tias xws li tweaks rau qhov ntsuas, Ampere Altra zoo li zoo nkauj heev nyob rau hauv cov nqe lus ntawm kev ua tau zoo thiab lub zog efficiency. Tus qauv 42U neeg rau zaub mov khib nrog lub zog 12,5 kW tuaj yeem ntim txog 3500 processor cores, txuag watts ib cores.
Thiab qhov no yog qhov pib xwb. Jeff Wittich tau hais tias hauv ib xyoos yuav muaj lwm yam khoom lag luam hauv khw, codenamed Mystique, uas Ampere yuav ntxiv cov cores ntxiv.
Mystique yuav txhawb nqa tib lub qhov (socket), yog li yuav tsis tas yuav hloov cov motherboard. Siryn SoC tiam tom ntej yog npaj rau tso tawm xyoo 2022.
Hauv xyoo tas los no, peb tau pom ntau qhov kev sim tso tawm ARM server processors los ntawm cov tuam txhab sib txawv: Broadcom/Cavium/Marvell, Calxeda, Huawei, Fujitsu, Phytium, Annapurna/Amazon thiab AppliedMicro/Ampere. Feem ntau ntawm cov kev sim no ua tsis tiav. Tab sis muaj cov cim qhia tias qhov xwm txheej hloov pauv. Lub Kaum Ob Hlis 2019, Amazon servers nrog 64-core ARM processors yog ib qho system-on-chip raws li tib core ARM Neoverse N1 core. Hauv qee qhov kev xeem, ARM piv txwv (M6g thiab M6gd) ua tau zoo dua, thiab qee zaum zoo dua, dua li x86.
Thaum lub Kaum Ib Hlis 2019, nws tau tshaj tawm tias Asmeskas pib Nuvia . Kev pib yog tsim los ntawm peb tus kws tshaj lij engineers uas tau koom nrog hauv kev tsim cov txheej txheem ntawm Apple thiab Google. Lawv kuj tau cog lus tias yuav tsim cov servers processors uas yuav sib tw nrog Intel thiab AMD. Los ntawm Nuvia tau tsim cov tub ntxhais processor los ntawm hauv av uas tuaj yeem ua rau saum ARM architecture, tab sis tsis tau txais daim ntawv tso cai ARM.
Tag nrho qhov no qhia tau hais tias RISC processors tuaj yeem nrhiav tau daim ntawv thov tsis yog hauv cov khoom siv mobile xwb, tab sis kuj nyob rau hauv servers, nrog rau hauv desktop computers thiab laptops. Los ntawm txoj kev, muaj lus xaiv hais tias .
Qhov tseeb, qhov tseeb iPad Pro qauv nrog ARM A12X processors yuav luag muaj zog npaum li 15-nti MacBook Pro nrog Core i7 thiab Core i9 processors, yog li qhov kev hloov kho no yuav yog qhov laj thawj heev.
