Ikhadi levidiyo le-AMD seliphinde laba umholi ezimayini ze-cryptocurrency ye-Ethereum. I-accelerator yezithombe ezihamba phambili i-Radeon VII ikwazile ukudlula amakhadi evidiyo adlule asekelwe ku-Vega, ne-Radeon Pro Duo esekelwe kuma-Fiji GPU amabili, ngisho nomholi wangaphambilini - i-NVIDIA Titan V esekelwe ku-Volta.
Ikhadi levidiyo le-Radeon VII eliphuma ebhokisini, okungukuthi, ngaphandle kokuguqulwa noma izinguquko, liyakwazi ukuhlinzeka ngesivinini sezimayini esingu-90 Mhash/s. Lokho cishe kuphindwe kathathu ukusebenza kweRadeon RX Vega 64 ngaphandle kwebhokisi, kanye no-29% ngaphezu kweRadeon Pro Duo. Umehluko nge-Titan V nawo ubalulekile - ikhadi levidiyo le-NVIDIA liyakwazi ukunikeza i-hashrate engu-69 Mhash/s ekucushweni okujwayelekile.
Usebenzisa ukukhohlisa okuhlukahlukene ngamapharamitha, ungakhuphula i-hashrate yekhadi levidiyo leRadeon VII lifike ku-100 Mhash/s. Kodwa-ke, kungaba ngcono kakhulu ukunciphisa ukusetshenziswa kwamandla kusuka ku-319 kuya ku-251 W, kuyilapho uvala inkumbulo ngokweqile ukusuka ku-1000 kuya ku-1100 MHz, futhi kuphoqe i-GPU ukuthi isebenze nge-voltage engu-950 mV imvamisa ye-1750 MHz. Ngaphansi kwezimo ezinjalo, izinga lokukhiqiza lizoba ngu-91 Mkhesh/s, kanti ukusebenza kahle kuzokwenyuka ngo-21%.
Kunjalo, kwamanye amakhadi evidiyo, usebenzisa ukulungiselelwa ungakwazi futhi ukuzuza ukwanda kwe-hashrate. Isibonelo, ku-Titan V, ukulungiselelwa kusivumela ukuthi sifinyelele ku-82 Mhash/s. Ngokulandelayo, iRadeon RX Vega 64 iyakwazi βukumba i-etherβ ngesivinini esingu-44 Mhash/s. Kuyaqapheleka futhi ukuthi kumakhadi wevidiyo we-NVIDIA GeForce GTX 1080 kanye ne-GTX 1080 Ti kukhona ama-patches esofthiwe akhethekile ahlinzeka ngokunyuka okuphawulekayo kwe-hashrate ku-40 kanye ne-50 Mhash, ngokulandelana, noma ngaphezulu. Lokhu futhi kunciphisa ukusetshenziswa kwamandla.
Uma kuqhathaniswa ne-Titan V, i-Radeon VII entsha ayinakho ukusebenza okuphezulu kuphela, kodwa futhi intengo ekhangayo kakhulu - amakhadi wevidiyo abiza u-$ 3000 no-$ 700, ngokulandelana. Uma iqhathaniswa namanye ama-accelerator ezithombe, i-Radeon VII ihamba kahle kakhulu ngokusebenza kanye nokusetshenziswa kwamandla. Isibonelo, i-Radeon RX 570 noma i-RX 580 ene-hashrate eqhathaniswa ne-Radeon VII eyodwa izosebenzisa amandla engeziwe. Endabeni ye-GeForce GTX 1080 ne-GTX 1080 Ti, isimo siyefana: ukusebenza okuqhathaniswayo kunikezwa ngokusetshenziswa kwamandla okuphezulu.
Ngingathanda futhi ukuhlala ngokwehlukana lapho umehluko omkhulu kangaka phakathi kweRadeon RX Vega 64 neRadeon VII uvelaphi. Konke kumayelana nenkumbulo kanye nomkhawulokudonsa wayo. Ngenkathi i-Radeon RX Vega 64 ine-8 GB HBM2 enomkhawulokudonsa ongu-484 GB/s, i-Radeon VII entsha ine-16 GB HBM2 enomkhawulokudonsa ongu-1 TB/s. Ngesikhathi esifanayo, ukusetshenziswa kwamandla kwamakhadi wevidiyo cishe kusezingeni elifanayo, okwenza i-Radeon VII ibe isisombululo esithakazelisayo kakhulu sokumba izimayini.
Kodwa-ke, kukhona ukungahambi kahle okusobala lapha: inzuzo yezimayini okwamanje ayikho ezingeni eliphezulu kakhulu, futhi ngisho ne-hashrate ephezulu kangaka, akunakwenzeka ukuthi kuzokwazi ukwenza inzuzo enkulu usebenzisa i-Radeon VII. Ukube nje leli khadi levidiyo belikhona unyaka nengxenye edlule...
