Posachedwapa pamwambo wochita bwino kwambiri pamakompyuta, wamkulu wa AMD wa Datacenter Group, Forrest Norrod, adagawana zambiri za mapurosesa omwe akubwera akampani yake. Makamaka, adanena kuti AMD tsopano ikupanga purosesa yatsopano yomwe imaphatikizapo kuyika DRAM ndi SRAM mwachindunji mu purosesa kuti igwire bwino ntchito.
Chifukwa chomwe AMD ikuyang'ana njira zatsopano zosinthira magwiridwe antchito a mapurosesa ake ndizosavuta - lamulo la Moore lafika polekezera. Zimakhala zovuta kwambiri kuchepetsa njira zamakono nthawi iliyonse, ndipo motero zimakhala zovuta kuonjezera chiwerengero cha transistors. Maulendo a wotchi nawonso afika pomaliza, ndipo ndizovuta kuwawonjezera pazantchito zazing'ono. M'malo mwake, munjira zaukadaulo "zosakhwima", ma frequency amatha kukhala otsika kuposa enieni. Chifukwa chake njira zatsopano zimafunikira kuti purosesa igwire bwino.
Chimodzi mwa izo ndi kugwiritsa ntchito "zomatira" za makhiristo angapo, ndiko kuti, ma CD-chip ambiri. Kupanga makhiristo angapo ang'onoang'ono m'malo mwa imodzi yayikulu kumakhala kosavuta komanso kothandiza kwambiri, motero ndikotsika mtengo. M'mapurosesa ake atsopano, AMD imagwiritsa ntchito makina otchedwa "chiplets". Mapurosesa atsopano a EPYC "Rome" amagwiritsa ntchito kuphatikiza makhiristo anayi okhala ndi ma cores ndi kristalo imodzi yokhala ndi chowongolera kukumbukira ndi mawonekedwe ena. Dongosolo lofananalo lidzakhala mu Ryzen 3000 yomwe ikubwera. Ndipo gawo lotsatira likhoza kukhala kuyika tchipisi pamwamba pa wina ndi mzake, m'matumba.
Monga opanga ena opanga semiconductor, AMD ikuyesetsa kusamukira ku zomangamanga za 3D kuti zithandizire kachulukidwe. Makamaka, AMD ikufuna kukhazikitsa makumbukidwe ozikidwa pa stack monga ikuwona ngati gawo lofunikira kwambiri posachedwa. Kampaniyo imagwiritsa ntchito kale kukumbukira kwa HBM2 ndi ma GPU ake. M'tsogolomu, AMD ikufuna kuyika tchipisi tokumbukira molunjika pamwamba pa tchipisi ta makompyuta (CPUs ndi ma GPU) kuti ipereke bandwidth yapamwamba motero ntchito yowonjezereka.
Lingaliro loyika kukumbukira pamwamba pa chip china silatsopano. Samsung yakhazikitsa kale zofanana, koma monga mukuwonera pazithunzi pamwambapa, kukumbukira komwe kuli pamwamba sikukulumikizidwa mwachindunji ndi chip china, koma kudzera pazowonjezera zina. Njirayi, ndithudi, imawonjezera kachulukidwe kayiyidwe, koma sichikhoza kupereka liwiro lalikulu lotengera deta. AMD ikufuna kukhazikitsa kukumbukira molunjika pa purosesa chip ndikuwalumikiza wina ndi mzake pogwiritsa ntchito TSV (kudzera pa silicon kudzera) kulumikiza kwamtundu. Izi zidzatsimikizira kuthamanga kwambiri kwa data pakati pa makhiristo awiriwa, zomwe zidzasintha ntchito. Njirayi imachepetsanso kugwiritsa ntchito mphamvu ndikuwonjezeranso kuchuluka kwa zonyamula.
Forrest Norrod sanafotokoze mwatsatanetsatane zomwe zikuchitika. Koma zikuwonekeratu kuti zomangamanga zomwe zimapangidwa ndi AMD, zomwe zimaphatikizapo kuyika kukumbukira pamwamba pazitsulo zowonongeka, zikhoza kukhala kusintha kwakukulu pakupanga ma processor a AMD. Dziwani kuti Intel tsopano ikugwiranso ntchito paukadaulo wa 3D chip placement, womwe umatchedwa 3D Foveros. Chifukwa chake m'tsogolomu titha kuwona mapurosesa a "volumetric" omwe azitha kupereka magwiridwe antchito atsopano poyerekeza ndi tchipisi tapano.
