Peb tab tom tham txog multi-core CPUs los ntawm cov tuam txhab lag luam thoob ntiaj teb.

48 cev
Thaum kawg ntawm 2018, Intel Cascade-AP architecture. Cov txheej txheem no yuav txhawb nqa mus txog 48 cores, muaj ntau daim ntawv teeb tsa thiab 12 raws ntawm DDR4 DRAM. Txoj hauv kev no yuav muab cov qib siab ntawm kev sib luag, uas muaj txiaj ntsig zoo hauv kev ua cov ntaub ntawv loj hauv huab. Kev tso tawm cov khoom raws li Cascade-AP yog teem rau 2019.
ntawm 48-core processors thiab hauv IBM nrog Samsung. Lawv tsim chips raws li architecture . Cov khoom siv tshiab yuav txhawb nqa OpenCAPI 4.0 raws tu qauv thiab NVLink 3.0 tsheb npav. Thawj zaug yuav muab rov qab sib raug zoo nrog POWER9, thiab qhov thib ob yuav ua kom cov ntaub ntawv hloov pauv ntawm lub khoos phis tawj nruab nrab txog 20 Gbit / s. Nws tseem paub tias POWER10 muaj I / O thev naus laus zis tshiab thiab txhim kho lub cim xeeb tswj.
Thaum xub thawj, cov chips yuav tsum tau tsim nyob rau hauv GlobalFoundries siv 10nm txheej txheem thev naus laus zis, tab sis tom qab ntawd qhov kev xaiv tau ua los ntawm TSMC thiab 7nm thev naus laus zis. Kev txhim kho yog npaj kom tiav ntawm 2020 thiab 2022. Los ntawm 2023, lub tuam txhab tseem yuav tso tawm POWER11 chips, tsim siv 7nm txheej txheem thev naus laus zis nrog transistor ntom ntawm 20 billion.
Los ntawm , 48-ntxhais Intel cov kev daws teeb meem ua haujlwm peb zaug sai dua li lawv cov neeg sib tw AMD (nrog 32 cores). Raws li rau POWER10, tsis muaj dab tsi paub txog nws qhov kev ua tau zoo. Tab sis tias cov tiam tshiab ntawm cov processors yuav pom daim ntawv thov nyob rau hauv lub tshav pob ntawm analytics thiab loj cov ntaub ntawv tsom xam.
56 cev
Cov chips zoo sib xws tau tshaj tawm tsis ntev los no los ntawm Intel - lawv yuav raug tsim los siv 14-nm txheej txheem thev naus laus zis. Lawv txhawb Optane DC nco modules raws li 3D Xpoint thiab muaj thaj ua rau thaj rau Spectre thiab Foreshadow vulnerabilities. Cov khoom siv tshiab tuaj nrog 12 lub cim xeeb raws thiab ntau lub tshuab ua kom nrawm rau kev daws teeb meem hauv huab, nrog rau kev ua haujlwm nrog AI thiab ML systems thiab 5G tes hauj lwm.
Tus qauv flagship nrog 56 cores yuav hu ua Platinum 9282. Lub moos zaus yuav yog 2,6 GHz, nrog lub peev xwm overclock rau 3,8 GHz. Lub nti muaj 77MB ntawm L3 cache, plaub caug PCIe 3.0 kab, thiab 400W ntawm lub hwj chim ib lub qhov (socket). Tus nqi ntawm processors pib los ntawm kaum txhiab las.
Developers tias Optane DC yuav txo lub sijhawm rov pib dua ntawm cov tshuab computer los ntawm ob peb feeb mus rau ob peb feeb. Tsis tas li ntawd, lub nti tshiab yuav tso cai rau koj ua haujlwm ntau lub tshuab virtual hauv huab ib puag ncig. 56-core processor yuav tsum txo tus nqi ntawm kev tswj hwm ib leeg VM los ntawm 30%. Txawm li cas los xij, cov kws tshaj lij tias cov txheej txheem tshiab yog qhov tseem ceeb hloov kho tshiab ntawm Xeon Scalable. Lub microarchitecture thiab moos ceev ntawm lub nti tseem zoo ib yam.

64 cev
Xws li ib tug processor nyob rau thaum xaus ntawm lub xyoo tas los ntawm AMD. Peb tab tom tham txog 64-core Epyc server chips tshiab raws li 7nm txheej txheem thev naus laus zis. Lawv yuav tsum tau nthuav tawm xyoo no. Tus naj npawb ntawm DDR4 raws yuav yog yim ntawm qhov zaus ntawm 2,2 GHz, thiab 256 MB ntawm L3 cache tseem yuav ntxiv. Yuav muaj chips 128 PCI Express 4.0 txoj kab es tsis txhob version 3.0, uas yuav muab ob npaug rau qhov kev sib tw.
Tab sis ib tug xov tooj ntawm Hacker News cov neeg nyob tias kev loj hlob ntawm kev tsim khoom tsis yog ib txwm muaj txiaj ntsig zoo rau cov neeg siv khoom. Ua raws li kev nrawm ntawm lub zog, tus nqi ntawm cov processors kuj nce, uas tuaj yeem txo cov neeg siv khoom xav tau.
Lub 64-core processor kuj tau tsim los ntawm Huawei. Lawv Kunpeng 920 chips yog ARM server processors. Kev tsim khoom yog ua los ntawm TSMC siv 7nm txheej txheem thev naus laus zis. TaiShan servers twb tau nruab nrog cov khoom siv tshiab nrog lub moos zaus ntawm 2,6 GHz, kev txhawb nqa rau PCIe 4.0 thiab CCIX interfaces. Cov yav tas yog tsim los ua haujlwm nrog cov ntaub ntawv loj thiab cov ntawv thov hauv huab.
Huawei processors twb tau qhia txog 20% kev ua tau zoo hauv kev sim nrog TaiShan servers. Tsis tas li ntawd, nco bandwidth tau nce 46% piv rau lub tuam txhab cov khoom dhau los.
Tag nrho
Feem ntau, peb tuaj yeem hais tias kev sib tw hauv server chip lag luam hauv 2019 yuav siab. Cov neeg tsim khoom tau ntxiv ntau thiab ntau cov cores, equipping processors nrog kev txhawb nqa rau cov ntaub ntawv hloov tshiab raws tu qauv, thiab sim ua cov khoom lag luam multitasking. Vim li no, cov tswv tsev cov ntaub ntawv muaj ntau lub sijhawm los xaiv cov kev daws teeb meem uas haum rau cov hom kev thauj khoom thiab cov haujlwm tshwj xeeb.
