Qhov kev hloov pauv pom tau zoo tshaj plaws hauv cov txheej txheem tau teev tseg hauv cov lus, thaum piv nrog rau yav dhau los Skylake-X 200 series qauv, yog qhov nce hauv moos ceev. Nominal zaus tau nce los ntawm 600-200 MHz, thiab qhov siab tshaj plaws zaus ua tiav thaum turbo hom qhib tau nce los ntawm 300-1,375 MHz. Tsis tas li ntawd, cov tub ntxhais hluas cov neeg sawv cev ntawm koob tau nce qhov ntim ntawm peb-theem cache nco. Yav dhau los, nws raug xam raws li txoj cai ntawm "2 MB ib core," tab sis tam sim no txhua tus tub ntxhais tuaj yeem muaj txog li 7 MB ntawm cache. Thiab thaum kawg, PCI Express maub los ntawm yim-ntxhais Core i9800-44X tau raug kaw tag nrho, ua tsaug rau cov txheej txheem no muaj nyob ntawm nws qhov kev pov tseg tag nrho 10 txoj kab, uas yav tas los tsuas muaj nyob rau hauv processors nrog XNUMX lossis ntau dua cores.
Txawm li cas los xij, tag nrho cov kev hloov pauv zoo li no ua rau muaj kev nce hauv kev tsim hluav taws xob. Thaum thawj tiam Skylake-X muaj pob thermal txwv rau 140 W, cov txheej txheem tshiab nce TDP tus yam ntxwv rau 165 W. Hauv lwm lo lus, rau qhov nce zaus uas tau muab rau cov txheej txheem tshiab yam tsis muaj kev hloov pauv hauv 14-nm cov txheej txheem thev naus laus zis siv rau lawv cov khoom tsim, koj yuav tsum them nrog kev nthuav dav zog thiab thermal txwv.
Muaj tseeb tiag, Intel nws tus kheej tau lees tias qhov kev taw qhia thib peb ntawm cov thev naus laus zis ntau lawm, code-named 14++ nm, uas tam sim no siv los tsim Coffee Lake thiab Coffee Lake Refresh processors, ua rau nws muaj peev xwm ua kom cov yam ntxwv nrawm. Thiab yog tias tsis yog rau qhov no, qhov tso cua sov tuaj yeem siab dua. Tab sis tsis muaj laj thawj ntshai tias Skylake-X tshiab tuaj yeem ua rau muaj kev kub ntxhov. Txhim kho thermal interface cov ntaub ntawv nyob rau hauv lub tshav kub faib npog yuav tsum txo cov kev khiav hauj lwm kub ntawm tshiab processors. Qhov chaw ntawm yav tas los siv polymer thermal muab tshuaj yog coj los ntawm solder nrog pom tseeb dua thermal conductivity.
Tab sis txhua yam uas tau hais los saum toj no tsuas yog qhov kawg ntawm cov dej khov. Qhov tseeb yog tias qhov kev hloov pauv hauv cov lus qhia tshwj xeeb, thiab feem ntau yog qhov nce ntawm qhov ntim ntawm peb-theem cache nco, muaj ntau qhov kev npaj txhij txog. Tam sim no, los tsim HEDT processors, Intel tau pib siv cov khoom siv hluav taws xob semiconductor uas txawv me ntsis hauv lub ntsiab lus.
Qhov no txhais tau hais tias cov hauv qab no: HEDT processors yeej ib txwm ua ntau yam desktop ntawm server chips. Raws li kev lig kev cai, Intel coj cov kev hloov kho tshiab ntawm Xeon, hloov kho lub cim xeeb tswj thiab qee cov yam ntxwv rau lawv, thiab xa lawv mus rau ib puag ncig desktop. Nyob rau tib lub sijhawm, thaum rau nws cov khoom server Intel tau tsim peb cov qauv ntawm cov khoom siv hluav taws xob semiconductor: LCC (Low Core suav) nrog 10 cores, HCC (High Core suav) nrog 18 cores thiab XCC (eXtreme Core suav) nrog 28 cores, hauv desktop HEDT cov txheej txheem suav nrog tsuas yog cov qauv yooj yim ntawm cov muaju. Yog li, thawj tiam Skylake-X processors nrog 6, 8 thiab 10 cores siv lub LCC siv lead ua, thiab kev hloov kho nrog 12, 14, 16 thiab 18 cores siv HCC siv lead ua.
Hauv qhov tshiab Skylake-X, uas peb tab tom tham txog niaj hnub no, qhov qis kawg ntawm LCC siv lead ua tsis siv lawm. Tag nrho cov txheej txheem HEDT tshiab ntawm cuaj txhiab series, suav nrog yim- thiab kaum-ntxhais versions, yog raws li HCC siv lead ua. Ntawd yog, txawm tias Core i7-9800X lossis Core i9-9900X muaj peev xwm muaj 18 cores, tab sis ib feem tseem ceeb ntawm lawv raug kaw hauv cov khoom siv ntawm theem tsim khoom.
Qhov kev txiav txim siab no, coj txawv txawv thaum xub thawj siab ib muag, tau ua kom meej meej kom nce tus nqi ntawm cache nco hauv cov txheej txheem tshiab. Cov qauv sab hauv ntawm Skylake-X xav tias txhua lub hauv paus hauv computer tau faib ib feem ntawm lub cim xeeb nrog lub ntim ntawm 1,375 MB. Thiab yog tias tib lub Core i9-9900X tau siv qhov qis kawg LCC siv lead ua, cov txheej txheem no yeej tsis tuaj yeem tau txais ntau dua 13,75 MB ntawm L3 cache. Qhov loj dua HCC tuag yog hloov tau ntau dua hauv qhov no, nws muaj tag nrho ntawm 24,75 MB ntawm cache, thiab qhov ntim tau nce no yog ib feem siv hauv yim- thiab kaum-ntxhais txheej txheem ntawm nthwv dej tshiab.
Raws li qhov tshwm sim, txhua qhov Skylake-X tau koom ua ke hauv kev tsim, tab sis qhov tsis zoo ntawm qhov kev sib koom ua ke no yog qhov kev siv dav dav ntawm cov khoom siv hluav taws xob loj heev tuag nrog thaj tsam ntawm 485 mm2, uas yog ntau tshaj li ob thiab ib nrab npaug loj dua. qhov chaw tuag ntawm yim-core Coffee Lake Refresh. Qhov no txhais tau hais tias ib qho ntawm LGA2066 processors ntawm cuaj txhiab koob muaj tus nqi siab dua piv rau tib Core i9-9900K. Tab sis txawm hais tias qhov no, yim-ntxhais Core i9-9800X hauv daim ntawv teev npe tus nqi tsuas yog $ 100 ntau dua li Core i9-9900K. Yog li ntawd, nws yog ib qho tsim nyog los xav tias qhov tsim ntawm yim- thiab kaum-ntxhais processors raws li 18-core crystals tseem ua rau qee qhov kev lag luam rau Intel, piv txwv li, lub tuam txhab siv lub sijhawm no los muag cov khoom siv hluav taws xob semiconductor nrog ntau qhov kev tsim khoom. tsis xws luag, uas txog rau tam sim no nrhiav tsis tau ib tug tsim nyog siv.
Xav paub ntau ntxiv txog kaum-core Core i9-9900X thiab Core i9-9820X
Rau kev sim, peb coj ob lub kaum-ntxhais processors ntawm "nthwv dej tshiab" - Core i9-9900X thiab Core i9-9820X. Txawm hais tias cov CPUs no tau tsiv mus rau HCC siv lead ua tshiab, lawv tsis tau hloov pauv ntau npaum li piv rau Core i9-7900X. Feem ntau, thaum tso ob tiam ntawm processors rau yav dhau los versions ntawm HEDT platform, Intel hloov lawv mus rau ib tug tshiab microarchitecture, tab sis qhov no tsis tau tshwm sim tam sim no. Cov kev hloov pauv cuam tshuam tsuas yog cov lej tsis sib xws, tab sis zoo nyob rau hauv daim ntawv ntawm Core i9-9900X thiab Core i9-9820X ββpeb muaj yuav luag tib yam uas tau muab los ntawm kaum-core Core i9-7900X ntawm 2017.
Tab sis tiam thib ob Skylake-X tsis muaj teeb meem kev sib raug zoo: lawv ua haujlwm zoo heev hauv LGA2066 motherboards uas twb muaj lawm raws li Intel X299 system logic teeb. Zoo li lawv cov neeg ua ntej, lawv muaj plaub-channel DDR4 lub cim xeeb tswj, thiab cov khoom siv hauv PCI Express 3.0 maub los txhawb 44 txoj kab, uas nyob rau hauv txoj kev xav tuaj yeem muab faib ua ntau qhov chaw - los ntawm peb mus rau kaum ib.
Txawm li cas los xij, HCC semiconductor siv lead ua hauv qab ntawm Core i9-9900X thiab Core i9-9820X ββyog qhov txawv me ntsis ntawm cov muaju uas tau siv hauv cov laus Skylake-X ua ntej. Txawm hais tias qhov kev nqis tes ua tau khaws cia M0 tus lej, uas yog qhov zoo rau thawj cov qauv ntawm Skylake-X nrog ntau dua 12 cores, Intel tam sim no tau pib siv hloov kho lithographic qhov ncauj qhov ntswg hauv cov txheej txheem tsim khoom vim yog kev siv ntau dua 14++ nm. txheej txheem thev naus laus zis tsis yog yav dhau los 14+ nm txheej txheem thev naus laus zis. Qhov sib txawv tseem ceeb ntawm cov thev naus laus zis yog qhov loj me me ntawm cov rooj vag transistor, uas, raws li peb tau pom nrog Coffee Lake, muaj txiaj ntsig zoo rau qhov muaj peev xwm ntau.
Ntawm qib microarchitecture, tsis muaj kev hloov pauv txhua. Kuj ceeb tias, tus tshiab Skylake-X Refresh processors tsis txawm suav nrog kev kho kho vajtse los tawm tsam Meltdown thiab Spectre qhov tsis zoo. Thiab qhov no yog qhov txawv heev vim qhov tseeb tias nyob rau hauv cov khoom sib txuas Coffee Lake Refresh, tso tawm tib lub sijhawm, qee qhov thaj ua rau pom twb tshwm sim. Piv txwv li, niaj hnub LGA1151v2 processors raug tiv thaiv los ntawm Meltdown (Variant 3) thiab L1TF (Variant 5) tawm tsam ntawm qib kho vajtse.
Tab sis qhov ntawd tsis yog qhov txaus ntshai tshaj plaws. Qhov laj thawj tseem ceeb rau kev ntxhov siab yog qhov tsis muaj kev hloov pauv hauv lub tswv yim ntawm kev sib txuas cov khoom sib txuas ua ke rau hauv ib qho tag nrho. Skylake-X Refresh txuas ntxiv siv cov phooj ywg-rau-tus phooj ywg mesh network overlayed rau saum cov array ntawm processor cores. Cov txheej txheem kev sib txuas ntawm cov tub ntxhais no ua haujlwm zoo nrog kev nce ntxiv ntawm cov cores hauv cov neeg rau zaub mov processors, tab sis rau HEDT cov khoom uas tsis muaj tus lej ntawm cov cores nws yog qhov phem dua rau cov tsheb npav ib txwm muaj, ua rau muaj kev nce siab hauv latencies. . Ib qho ntawm txoj hauv kev los tawm tsam qhov tsis zoo no tuaj yeem ua kom nrawm Mesh kev sib txuas, tab sis ntawm no txhua yam tseem zoo li qub. Kev khiav hauj lwm zaus ntawm kev sib txuas hauv ob qho tib si yav dhau los thiab tam sim no Skylake-X tau teeb tsa ntawm 2,4 GHz, yog li L3 cache thiab lub cim xeeb ntawm LGA2066 processors tau pom qhov tsis zoo latency piv rau Coffee Lake Refresh loj. Muaj tseeb, qhov no yog ib feem them nyiaj los ntawm kev nthuav dav thib ob-theem cache, uas nyob rau hauv Skylake-X muaj qhov ntim ntawm 1 MB ib qho tseem ceeb, thiab tsis yog plaub zaug tsawg dua.
Tag nrho cov no tuaj yeem pom tau yooj yim los ntawm daim duab ntawm latency ntawm lub cim xeeb subsystem ntawm cov tiam tam sim no Skylake-X processors piv nrog Coffee Lake Refresh. Nws qhia meej txog qhov tsis muaj kev txhim kho hauv qhov xwm txheej latency ntawm HEDT processors tshiab.
