USB4 2.0 Tere Rua, Kua Tae Mai te Ao o Muri Mai
I te whakatinanatanga a ngā kaihanga papahoahoa PC40 Gbps USB4, kāore e taea e te iwi te kore e whakaaro he aha te whāinga e whai ake nei o tēnei paerewa hononga whānui? Ko te USB4 2.0 te mea e whakarato ana80 Gbpste whānui raraunga i ia ahunga me te tuku hiko 60W (PD) mō te hononga. Ka taea e te tuku hiko o te USB4 2.0 te eke ki te 240 W (48 V, 5 A). He maha ngā putanga o te USB, ka taea te kī he rerekē. Heoi, nā te whakakotahitanga āta o ngā atanga, kua tino heke te maha o ngā putanga USB. I te wā o te USB4, ko te atanga USB-C anake e toe ana. He aha i noho tonu ai he putanga 2.0? Ko te whakahoutanga putanga nui rawa atu o te USB4 2.0 ko tana tautoko i te tere whakawhiti raraunga tae atu ki te 80 Gbps, he nui ake i te atanga Thunderbolt 4. Me ruku hohonu ki ngā taipitopito.
I mua, i whakawhanakehia te paerewa USB4 1.0 i runga i te hangarau Thunderbolt 3, me te tere whakawhiti raraunga mōrahi o40 GbpsI whakawhanakehia te putanga 2.0 i runga i tētahi hoahoa paparanga ā-tinana hou, e whakapiki ana i te tere whakawhiti raraunga mai i te tihi o te 40 Gbps ki te 80 Gbps, e whakatakoto ana i tētahi tuanui mahi hou mō te pūnaha USB-C. Me mōhio ko te tere 80 Gbps hou e hiahia ana ki ngā taura hohe, ā, tera pea ka tautokona e ētahi hua teitei anake ā muri ake nei. Ko teUSB4 2.0Kua whakahoutia hoki te hoahoanga raraunga. Nā te hoahoanga paparanga ā-tinana hou e hangai ana ki te tikanga whakakōwae tohu PAM3 me te taura raraunga hohe 80 Gbps kua tautuhia houtia, ka taea e ngā taputapu te whakamahi katoa me te whai tikanga i te whānui o te hononga. Ka pā anō tēnei whakahoutanga kiUSB 3.2, te tuku ataata DisplayPort, me ngā hongere raraunga PCI Express. I mua, ko te tere whakawhiti mōrahi o te USB 3.2 he 20 Gbps (USB3.2 Gen2x2)I raro i te hoahoa raraunga hou, ka neke atu te tere o te USB 3.2 i te 20 Gbps, ā, ka eke ki tētahi whakatakotoranga teitei ake.
Mō te hototahitanga, ka hototahi te USB4 2.0 ki te USB4 1.0, USB 3.2, me te Thunderbolt 3, nō reira kāore he take e manukanuka ai ki ngā take hototahitanga. Hei tāpiri, kia pai ai te tere whakawhiti raraunga o te 80Gbps, he pūnaha hou, kaha hokiUSB-C ki te USB-CMe whai taura raraunga hei whakatutuki i tēnei tere. Ko te whānuitanga mōrahi o ngā taura raraunga USB-C ki te USB-C kore mahi me te ā-whakauru he 40Gbps tonu. Hei whakamārama ake i ngā kāwai o nāianei o te USB, kua tīmata te whakakotahi i te atanga USB mā te whakaingoa i runga i te whānuitanga tuku. Hei tauira, ko te USB4 v2.0 e rite ana ki te USB 80Gbps, ko te USB4 e rite ana kiUSB 40Gbps, USB 3.2 Gen2x2e rite ana ki te 20Gbps, e rite ana te USB 3.2 Gen2 kiUSB 10Gbps, meUSB 3.2 Gen1e rite ana ki te USB 5Gbps, me ētahi atu. Ka kitea ngā tapanga takai, ngā tapanga atanga, me ngā tapanga taura raraunga i te pikitia e whai ake nei.
I te marama o Oketopa 2022, kua tukuna kētia e USB-IF te whakatakotoranga USB4 putanga 2.0, ka taea te whakatutuki i te mahi tuku o te 80 Gbps. Ko ngā mea e pā anaMomo-C USBmeTukunga Hiko USB (USB PD)Kua whakahoutia hoki ngā whakatakotoranga. I raro i te whakatakotoranga USB4 putanga 2.0, ka taea hoki te whirihora i te atanga tohu USB Momo-C kia kore e ōrite te āhua, ka taea te tere mōrahi tae atu ki te 120 Gbps i te taha kotahi, me te pupuri tonu i te tere o te 40 Gbps i te taha kē. I tēnei wā, he maha ngā aroturuki 4K teitei e tautoko ana i te hononga raina kotahi USB-C mō ngā pona. Whai muri i te whakarewatanga o te otinga USB4 2.0 80 Gbps, ko ētahi4K 144HzKa taea e ngā mata tirotiro, ngā mata tirotiro 6K, 8K rānei te hono ngāwari ki ngā pona mā te USB-C. Kei te pupuri tonu te atanga USB 80 Gbps i te tauranga USB Momo-C hei whakarite i te hototahitanga ki ngā putanga USB 4 Putanga 1.0, USB 3.2, USB 2.0 me te Thunderbolt 3 o nāianei. Hei tāpiri, ko te "Tara Raraunga Momo-C USB 80 Gbps" i tukuna i te mutunga o tēnei tau e tautoko ana i te putanga tere-katoa o te tere 80 Gbps me te tautoko hoki i te mana utu o te 240W 48V/5A (USB PD EPR). Ko ngā pona o te whakatupuranga hou e tumanakohia ana ka whakarewaina i te mutunga o tēnei tau, i te tau e tū mai nei rānei, e tumanakohia ana ka tīmata te tautoko i te USB 80 Gbps. I tētahi taha, ka taea e ngā PC petipeti me ngā mata tirotiro te whakamahi pai ake i te mahi kāri whakairoiro; i tētahi atu taha, ka taea hoki e te PCIe totoka-waho te whakahaere ki te kaha katoa.
