Adam Kos Apple yakaunza duo yeMacBook Pros iyo inosiyana kwete chete mudiagonal yezviratidziro zvavo. Zvinoenderana nesarudzo yako, unogona kuamisa nemachipi akasiyana. Tine maviri ekusarudza kubva pano - M1 Pro uye M1 Max. Yekutanga inogona kusanganiswa kusvika ku32GB ye RAM, yechipiri inosvika ku64GB ye RAM. Ivo vanosiyana zvakanyanya mukufambisa, nekutanga kupa kusvika ku200 GB/s, yechipiri 400 GB/s. Asi izvozvo zvinorevei?
Mumabhuku ekunyora ehunyanzvi, data rinofanirwa kukopwa nekudzoka kuburikidza nezvakataurwa naApple iratidziro inononoka. Nekudaro, iyo itsva MacBook Pro inozviita zvakasiyana. Yayo CPU neGPU inogovera inobatika block yeyakabatana ndangariro, zvichireva kuti ese mativi eiyo chip yekuwana data uye ndangariro pasina kutevedzera chero chinhu. Izvi zvinoita kuti zvese zviitike nekukurumidza uye zvakanyanya.

Kuenzanisa nemakwikwi
Memory bandwidth (memory bandwidth) ndiyo yakanyanya kumhanya iyo data inogona kuverengerwa kana kuchengetwa mu semiconductor memory ne chip/processor. Inopihwa muGB pasekondi. Dai taizotarisa mhinduro yeIntel, saka maCore X akatevedzana ma processors ane kubuda kwe94 GB/s.
Zvinogona kudaro kufarira iwe
Saka akahwina akajeka mukuenzanisa uku ndeyeApple's "Unified Memory Architecture," iyo inopa ndangariro kupfuudza kanokwana kaviri nekukurumidza sekukwikwidza kwakananga kweIntel parizvino. E.g. Iyo Sony Playstation 5 ine bandwidth ye448 GB/s. Asi ramba uchifunga kuti huwandu hwepamusoro hunoenderanawo nekusiyana kwakawanda muhurongwa uye software yebasa, pamwe nechimiro chesimba.

Kubva pamiyedzo Geekbench zvino zvinozoitika kuti M1 Max ine 400 GB/s inowana zvingangoita gumi muzana zviri nani akawanda-epakati zvibodzwa pane iyo M10 Pro ine mazana maviri GB/s. Nekudaro, iwe unofanirwa kuzvitongera wega kana kukosha uku kwakakodzera mari inokwanisika yekuwedzera. Michina miviri ine simba kwazvo uye zvinoenderana nemaitiro ebasa rako. Nekudaro, ichokwadi kuti iyo yepamusoro dhizaini ine mukana uri nani maererano neramangwana, apo ichave ichiri kukwanisa kuita nekukurumidza basa rakakwana kunyangwe mushure menguva yakareba. Asi pano zvinoenderana nekuti kangani iwe unoshandura nzvimbo yako yekushanda. Parizvino, zvinogona kutaurwa kuti 1 GB/s yakanyatsokwana kune mazhinji ebasa raungade kubva kuMacBook Pro itsva.

Neramangwana mupfungwa, ini zvechokwadi ndinoda iyo yepamusoro dhizaini pane chip. Ndine madhiraivha ekunze uye maNAS uye nezvimwe, saka ini handifanire kuivhara imomo. Asi ini ndagara ndichifunga kuti chip uye magiraidhi ndiyo ine simba zvakanyanya, saka ini ndicharambira nazvo.
