Lub rooj sib tham Semicon West 2019, muaj nyob rau hauv kev txhawb nqa ntawm Applied Materials, twb tau txais cov txiv hmab txiv ntoo hauv daim ntawv ntawm cov lus nthuav tawm los ntawm AMD CEO Lisa Su. Txawm hais tias AMD nws tus kheej tsis tau tsim cov txheej txheem ntawm nws tus kheej rau lub sijhawm ntev, xyoo no nws tau tshaj nws cov neeg sib tw tseem ceeb ntawm cov qib ntawm kev nce qib ntawm cov thev naus laus zis siv. Txawm hais tias GlobalFoundries tshuav AMD ib leeg nrog TSMC hauv kev sib tw rau 7nm cov qauv thev naus laus zis, kev ua tiav hauv kev ua tiav qib ntawm cov txheej txheem lithographic feem ntau yog vim AMD. Thaum kawg, lub tuam txhab txuas ntxiv tsim nws cov txheej txheem ntawm nws tus kheej, thiab TSMC tsuas yog muab los hloov cov haujlwm no rau nws cov peev txheej tsim khoom.
Raws li ib tug yuav txiav txim los ntawm fragmentary duab luam tawm nyob rau hauv Kev lag luam blogger David Schor, ntawm Semicon West lub rooj sib tham, Lisa Su tau kov cov teeb meem tam sim no ntsib kev lag luam semiconductor. Hauv AMD txoj kev nkag siab, nws tseem ntxov dhau los sau tawm qhov hu ua "Moore's Law" raws li kev xav tsis raug, txij li nws tau nce qib hauv thaj chaw lithographic uas tso cai rau lub tuam txhab ua ob npaug ntawm kev ua haujlwm ntawm cov txheej txheem dhau los ob thiab ib nrab xyoo dhau los. piv rau cov khoom ntawm kaum xyoo dhau los.
Txawm li cas los xij, cov txheej txheem thev naus laus zis hauv qhov xwm txheej no suav nrog tsawg kawg 40% ntawm qhov kev pab cuam rau kev ua haujlwm nce ntxiv, raws li AMD sau tseg ntawm tus swb. Yog tias peb ntxiv rau qhov no ntxiv 20%, muab los ntawm kev ua kom zoo ntawm qib silicon, peb tau txais tag nrho 60%. Kev hloov pauv ntawm qib microarchitecture suav txog 17% ntawm tag nrho qhov nce, kev tswj fais fab suav txog 15%, thiab compilers suav txog 8%. Txawm tias ib tug yuav hais li cas, tsis muaj kev vam meej hauv kev lag luam lithography, AMD yuav tsis muaj peev xwm ua tiav cov kev vam meej.
AMD kev tswj hwm kuj tseem sau lwm qhov sib txawv: cov txheej txheem kev ua haujlwm nyias nyias, cov khoom siv lead ua kim kim dua yuav tsim. Piv txwv li, ib tug siv lead ua siv lead ua nrog ib tug tub ntxhais cheeb tsam ntawm 250 mm2 thaum tsiv los ntawm 45 nm mus rau ib tug 5 nm txheej txheem technology yuav yog tsib lub sij hawm kim kim nyob rau theem ntawm ib tug tshwj xeeb nqi ib chav tsev. Yog li, txhawm rau tswj hwm tus nqi tsim nyog tau txais txiaj ntsig, processor chips yuav tsum ua kom zoo dua. AMD tab tom siv qhov kev tshawb fawb no los ntawm kev hloov mus rau kev siv lub npe hu ua "chiplets" - cov muaju me me ua ke ntawm ib qho substrate.
Qhov thib peb swb, ntes los ntawm blogger lub koob yees duab, tham txog kev faib cov neeg siv hluav taws xob hauv cov txheej txheem niaj hnub nrog kev sib koom ua ke siab. Tsuas yog ib feem peb ntawm kev siv hluav taws xob vim yog kev ua haujlwm suav. Tus so yog coj los ntawm cache nco, input/output logic, thiab ntau yam interfaces. TDP qib rau server CPUs thiab GPUs tau nce 2006% txhua xyoo txij li xyoo 7, raws li AMD. Kev ua tau zoo ntawm kev siv hluav taws xob tsis yog siab npaum li peb xav tau.
