Pakutanga kwegore rinouya, AMD inoronga kuunza yekutanga Ryzen 4000 akateedzana processors - mobile hybrid chips yemhuri yeRenoir. Uye kana zvese zvaive zvakanyanya kana zvishoma kujeka neiyo processor chikamu - machipi achave neZen 2 cores, ipapo neakasanganiswa magiraidhi zvese hazvina kujeka. Nekudaro, ikozvino ruzivo rwakaonekwa paInternet maererano neakasanganiswa magiraidhi ayo maAPU achagashira. Uye ngationei nekukurumidza kuti iyi ichave mifananidzo ine Vega architecture.
Nzvimbo inozivikanwa yekudonha pasi pezita remanyepo Komachi yakaburitsa runyorwa rwema processor kubva kumhuri yeRenoir, kusanganisira Ryzen 5, Ryzen 7 uye kunyange Ryzen 9 chips, pamwe nenhamba yeRyzen Pro akateedzana modhi. Zvinofungidzirwa kuti mazita B10, B12 uye akafanana anoratidza kugadziridzwa kweakasanganiswa magirafu emachipi aya. Ndiko kuti, nhamba iri pano inoratidza nhamba yeCompute Units (CUs) yemifananidzo yakabatanidzwa. Semuenzaniso, Ryzen 9 ine "B12" mifananidzo inonzi ine gumi nemaviri CUs.
B12 = 12CU.
つまり、Renoir “Mobile” APUのiGPUは12CUですか.— 比屋定さんの戯れ言@Komachi (@KOMACHI_ENSAKA)
Ziva kuti ikozvino AMD mahybrid processors ane huwandu hwegumi nerimwe computing unit pane akasanganiswa magiraidhi. Kuwedzera kwenhamba yeCUs muchizvarwa chinotevera kuchafambiswa nekuchinja kune 11-nm process technology. Izvi zvinogona zvakare kubatsira kuwedzera wachi kumhanya kweiyo yakasanganiswa magiraidhi uchichengetedza yakaderera mashandisiro emagetsi, inova inonyanya kukosha parameter kune mobile processors.
Kune zvakare mazano ekuti kuwedzera kuVega 12, isu tinogona kuona mamwe epamberi "akavakirwa-mukati". Sezvakataurwa neanofarira komputa ine pseudonym Locuza, kana AMD ikaburitsa yakasanganiswa mifananidzo Vega 13, ipapo kutaridzika kweVega 15 kunogoneka.Chinhu ndechekuti muVega architecture, kune yega yega 32 KB yekuraira cache (L $) uye 16. KB yenguva dzose cache (K $) inogona kuverengera kusvika matatu maCU. Nekuda kweizvozvo, tinogona kuwana kusvika gumi nemaviri (12 × 4) kana kusvika gumi nemashanu (3 × 15) computational units.
Ehe, ruzivo rwese rwuri pamusoro apa runyerekupe chete panguva ino. Nekudaro, kana zvikazove chokwadi, saka muchizvarwa chinotevera che AMD hybrid processors tichawana zvakare yakasanganiswa Vega mifananidzo (GCN5), uye AMD ichashandisa yazvino Navi (RDNA) mumaGPU akabatanidzwa gare gare. Zvisinei, kubereka kunofanira kuwedzera zvakanyanya. Kana AMD ikashandisa kunyange gumi nemaviri CUs uye ichisimudza mafambiro, ipapo magirafu eRenoir processors achakwanisa nekuzvimba kupfuura iyo "yakavakirwa-mukati" Intel Iris Plus G12 muIce Lake chips, uye negumi neshanu CUs inogona kukunda iyo discrete mifananidzo. yeGeForce MX7 level.
