I ka pō nei, ua puka mai kahi palapala ʻenehana ma ka Pūnaewele e wehewehe ana i kekahi o nā hiʻohiʻona o nā kaʻina hana Ryzen 4000 i manaʻo ʻia i kūkulu ʻia ma ka microarchitecture Zen 3. Ma ka laulā, ʻaʻole ia i lawe mai i nā hōʻike kūikawā, akā ua hōʻoia i ka nui o nā manaʻo i hana mua ʻia. .
E like me ka palapala, Ryzen 4000 processors (codename Vermeer) e hoʻopaʻa i ka chiplet layout i hoʻokomo ʻia i ko lākou mau mua o ka hanauna Zen 2. ʻO nā mea hana nui o ka wā e hiki mai ana, e like me ka wā ma mua, e loaʻa i kahi chiplet I / O a hoʻokahi a ʻelua mau CCD ( Core Complex Die) - nā chiplets i loaʻa nā core computing.
ʻO ka ʻokoʻa koʻikoʻi ma waena o nā kaʻina hana Zen 3 ʻo ia ke ʻano o loko o ka CCD. ʻOiai i kēia manawa aia i kēlā me kēia CCD ʻelua quad-core CCX (Core Complex), ʻo kēlā me kēia me kāna ʻāpana cache 3 MB L16 ponoʻī, ʻo ka Ryzen 4000 chiplets e loaʻa i hoʻokahi CCX ʻewalu-core. E hoʻonui ʻia ka nui o L3 cache i kēlā me kēia CCX mai 16 a 32 MB, akā ʻaʻole maopopo kēia e alakaʻi i ka hoʻololi ʻana i ka nui o ka mana hoʻomanaʻo cache. ʻEwalu-core Ryzen 4000 series processors, e loaʻa iā ia hoʻokahi chiplet CCD i kēia manawa, e loaʻa iā 32 MB L3 cache, a me 16-core CPUs me ʻelua chiplets CCD e loaʻa iā 64 MB L3 cache, i haku ʻia i ʻelua mau ʻāpana.
ʻAʻohe pono e manaʻo i nā loli i ka nui o ka cache L2: e loaʻa i kēlā me kēia kaʻina kaʻina hana he 512 KB o ka cache pae ʻelua.
Eia naʻe, ʻo ka hoʻonui ʻana i ka CCX e loaʻa i kahi hopena maopopo i ka hana. Loaʻa i kēlā me kēia cores i Zen 3 ke komo pololei i kahi ʻāpana nui o ka cache L3, a ʻoi aku ka nui o nā cores e hiki ke kamaʻilio pololei, e kāpae ana i ka Infinity Fabric. ʻO kēia ke kumu e hōʻemi ai ʻo Zen XNUMX i ka latency kamaʻilio inter-core a hōʻemi i ka hopena o ka hana o ka bandwidth palena o ka Infinity Fabric bus o ka mea hana, ʻo ia hoʻi e hoʻonui ʻia ka hōʻailona IPC (nā kuhikuhi i hoʻokō ʻia i kēlā me kēia hola).
I ka manawa like, ʻaʻole mākou e kamaʻilio e pili ana i ka hoʻonui ʻana i ka helu o nā cores i nā mea hoʻohana mea kūʻai. E kaupalena ʻia ka helu kiʻekiʻe o nā chiplets CCD i ka Ryzen 4000 i ʻelua, no laila ʻaʻole hiki ke ʻoi aku ka nui o nā cores i loko o ke kaʻina hana ma mua o 16.
Eia kekahi, ʻaʻohe loli koʻikoʻi i manaʻo ʻia me ke kākoʻo hoʻomanaʻo. E like me kēia mai ka palapala, ʻo ke ʻano kākoʻo kākoʻo kiʻekiʻe loa no ka Ryzen 4000 e noho DDR4-3200.
ʻAʻole hāʻawi ka palapala i nā kikoʻī e pili ana i ke ʻano o ke ʻano hoʻohālike a me nā alapine o nā mea hana i hoʻokomo ʻia i loko. E ʻike ʻia ka ʻike kikoʻī hou aku ma ʻOkakopa 8, i ka manawa e mālama ai ʻo AMD i kahi hanana kūikawā i hoʻolaʻa ʻia i nā kaʻina hana Ryzen 4000 a me ka Zen 3 microarchitecture.
