Ikhadi levidiyo le-AMD liphinde laba yinkokeli kwimigodi ye-cryptocurrency ye-Ethereum. I-accelerator yemizobo yeflegi iRadeon VII ikwazile ukogqitha amakhadi evidiyo angaphambili asekwe kwiVega, kunye neRadeon Pro Duo esekwe kwiiFiji GPU ezimbini, kunye nenkokeli yangaphambili - iNVIDIA Titan V esekwe kwiVolta.
Ikhadi levidiyo leRadeon VII ngaphandle kwebhokisi, oko kukuthi, ngaphandle kokuguqulwa okanye utshintsho, iyakwazi ukubonelela ngesantya sokumbiwa kwemigodi ye-90 Mhash / s. Iphantse yaphinda kathathu ukusebenza kweRadeon RX Vega 64 ngaphandle kwebhokisi, kunye ne-29% ngaphezulu kweRadeon Pro Duo. Umahluko kunye ne-Titan V nayo ibalulekile - ikhadi levidiyo le-NVIDIA liyakwazi ukubonelela nge-hashrate ye-69 Mhash / s kwi-standard configuration.
Ukusebenzisa ii-manipulations ezahlukeneyo kunye neeparameters, unokwandisa i-hashrate yekhadi levidiyo ye-Radeon VII ukuya kwi-100 Mhash / s. Nangona kunjalo, kuya kuba ngcono kakhulu ukunciphisa ukusetyenziswa kwamandla ukusuka kwi-319 ukuya kwi-251 W, ngelixa ugqithise imemori ukusuka kwi-1000 ukuya kwi-1100 MHz, kunye nokunyanzela i-GPU ukuba isebenze kumbane we-950 mV kwi-frequency ye-1750 MHz. Ngaphantsi kweemeko ezinjalo, izinga lokuvelisa liya kuba yi-91 Mkhesh / s, kwaye ukusebenza kakuhle kuya kunyuka nge-21%.
Ewe kunjalo, kwamanye amakhadi evidiyo, usebenzisa i-optimizations unokufezekisa ukonyuka kwe-hashrate. Umzekelo, kwi-Titan V, ukulungiswa kusivumela ukuba sifikelele kwi-82 Mhash / s. Ngaloo ndlela, i-Radeon RX Vega 64 iyakwazi "i-ether ye-mining" ngesantya se-44 Mhash / s. Kuyafaneleka ukuba uqaphele ukuba kwi-NVIDIA GeForce GTX 1080 kunye ne-GTX 1080 Ti amakhadi evidiyo kukho iipatches ezikhethekileyo zesofthiwe ezibonelela ngokunyuka okukhulu kwe-hashrate kwi-40 kunye ne-50 Mhash, ngokulandelanayo, okanye nangaphezulu. Oku kunciphisa ukusetyenziswa kwamandla.
Xa kuthelekiswa ne-Titan V, i-Radeon VII entsha ayinayo kuphela ukusebenza okuphezulu, kodwa kunye nexabiso elikhangayo kakhulu - amakhadi evidiyo axabisa i-$ 3000 kunye ne-$ 700, ngokulandelanayo. Xa kuthelekiswa nezinye ii-accelerators zegraphic, iRadeon VII igqwesile ngokwendlela yokusebenza kunye nokusetyenziswa kwamandla. Ngokomzekelo, ezintathu iRadeon RX 570 okanye i-RX 580 ene-hashrate ethelekiswa ne-Radeon VII enye iya kudla amandla amaninzi. Kwimeko ye-GeForce GTX 1080 kunye ne-GTX 1080 Ti, imeko iyafana: ukusebenza okufaniswayo kunikezelwa ngokusetyenziswa kwamandla aphezulu.
Ndingathanda ukuhlala ngokwahlukeneyo apho umahluko omkhulu kangaka phakathi kweRadeon RX Vega 64 kunye neRadeon VII uvela khona. Konke malunga nememori kunye ne-bandwidth yayo. Ngoxa i-Radeon RX Vega 64 ine-8 GB HBM2 kunye ne-484 GB / s bandwidth, i-Radeon VII entsha ine-16 GB HBM2 kunye ne-1 TB / s bandwidth. Kwangaxeshanye, ukusetyenziswa kwamandla amakhadi evidiyo malunga kwinqanaba elifanayo, nto leyo eyenza Radeon VII isisombululo umdla kakhulu kwimigodi.
Nangona kunjalo, kukho ukungahambi kakuhle okucacileyo apha: inzuzo yezimayini okwangoku ayikho kwinqanaba eliphezulu, kwaye nangona i-hashrate ephezulu, akunakwenzeka ukuba kuya kwenzeka ukuba wenze inzuzo enkulu usebenzisa i-Radeon VII. Ukuba nje eli khadi levidiyo belikhona kunyaka onesiqingatha eyadlulayo...
